Green roofs: potential at LANL  

SciTech Connect

Green roofs, roof systems that support vegetation, are rapidly becoming one of the most popular sustainable methods to combat urban environmental problems in North America. An extensive list of literature has been published in the past three decades recording the ecological benefits of green roofs; and now those benefits have been measured in enumerated data as a means to analyze the costs and returns of green roof technology. Most recently several studies have made substantial progress quantifying the monetary savings associated with storm water mitigation, the lessoning of the Urban Heat Island, and reduction of building cooling demands due to the implementation of green roof systems. Like any natural vegetation, a green roof is capable of absorbing the precipitation that falls on it. This capability has shown to significantly decrease the amount of storm water runoff produced by buildings as well as slow the rate at which runoff is dispensed. As a result of this reduction in volume and velocity, storm drains and sewage systems are relieved of any excess stress they might experience in a storm. For many municipalities and private building owners, any increase in storm water mitigation can result in major tax incentives and revenue that does not have to be spent on extra water treatments. Along with absorption of water, vegetation on green roofs is also capable of transpiration, the process by which moisture is evaporated into the air to cool ambient temperatures. This natural process aims to minimize the Urban Heat Island Effect, a phenomenon brought on by the dark and paved surfaces that increases air temperatures in urban cores. As the sun distributes solar radiation over a city's area, dark surfaces such as bitumen rooftops absorb solar rays and their heat. That heat is later released during the evening hours and the ambient temperatures do not cool as they normally would, creating an island of constant heat. Such excessively high temperatures induce heat strokes, heat exhaustion, and pollution that can agitate the respiratory system. The most significant savings associated with green roofs is in the reduction of cooling demands due to the green roof's thermal mass and their insulating properties. Unlike a conventional roof system, a green roof does not absorb solar radiation and transfer that heat into the interior of a building. Instead the vegetation acts as a shade barrier and stabilizes the roof temperature so that interior temperatures remain comfortable for the occupants. Consequently there is less of a demand for air conditioning, and thus less money spent on energy. At LANL the potential of green roof systems has already been realized with the construction of the accessible green roof on the Otowi building. To further explore the possibilities and prospective benefits of green roofs though, the initial capital costs must be invested. Three buildings, TA-03-1698, TA-03-0502, and TA-53-0031 have all been identified as sound candidates for a green roof retrofit project. It is recommended that LANL proceed with further analysis of these projects and implementation of the green roofs. Furthermore, it is recommended that an urban forestry program be initiated to provide supplemental support to the environmental goals of green roofs. The obstacles barring green roof construction are most often budgetary and structural concerns. Given proper resources, however, the engineers and design professionals at LANL would surely succeed in the proper implementation of green roof systems so as to optimize their ecological and monetary benefits for the entire organization.

Energy Performance Aspects of a Florida Green Roof Part 2  

E-Print Network (OSTI)

Green roof installation in the United States is growing at a significant rate. There are a number of reasons for this growth including rainwater runoff reduction and aesthetic benefits. Energy performance evaluations of green roofs, the subject of this study, are also becoming available. This monitored study is an evaluation of summer and winter energy performance aspects of a green roof on a 2-story central Florida university building addition that was completed in 2005. An earlier report on this study was published through the 2006 Symposium on Improving Building Systems in Hot and Humid Climates. This report reviews these earlier results and provides second-summer results which show significant performance improvements for the green roof compared with the first summer results. One half of the two-story project buildings 3,300 square foot project roof is a light-colored, conventional flat membrane roof, the other half being the same membrane roof covered with 6 to 8 of plant media and a variety of primarily native Florida vegetation up to approximately 2 feet in height to create an extensive green roof. Analysis of 2005 summer data from the first year the green roof was installed indicates significantly lower peak roof surface temperatures for the green roof compared with the conventional roof and a significant shift in when the peak green roof temperature occurs compared to the conventional roof. Data analysis of the same 2005 period also shows lower heat fluxes for the green roof. Calculations show the green roof to have an average heat flux of 0.39 Btu/ft2hr or 18.3% less than the conventional roofs average heat fluxrate of 0.48 Btu/ft2hr. Analysis of 2006 summer data when the green roof was more established and conventional roof somewhat darker, shows even greater temperature and heat flux differences between the two roofs. The weighted average heat flux rate over the 2006 summer period for the green roof is 0.34 Btu/ft2hr or 44.1% less than the conventional roofs average heat flux rate of 0.60 Btu/ft2hr. An additional heat flux analysis was performed for an April 1st 2006 through October 31st 2006 monitoring period to provide an estimate of heat flux for an extended cooling season. The weighted average heat flux rate over the period for the green roof is 0.25 Btu/ft2hr or 45.7% less than the conventional roofs average heat flux rate of 0.46 Btu/ft2hr. Winter data again show substantially lower peak roof surface temperatures, higher nighttime surface temperatures and significantly lower heat flux rates for the green roof compared with the conventional roof. For periods during which the ambient air temperature was less than 55oF, the weighted average winter heat flux rate for the green roof is -0.40 Btu/ft2hr or 49.5% less than the conventional roofs average heat flux rate of -0.79 Btu/ft2hr. Because of air conditioning zoning limitations, an extensive energy savings analysis was not possible for this project. However, an energy savings analysis was performed using the roof heat flux results and equipment efficiency assumptions. Based on this analysis the total estimated cooling and heating season savings for the green roof compared with the conventional roof, if the entire 3,300 square foot project roof were green, would be approximately 489 kWhr/yr.

Rooftop Membrane Temperature Reductions with Green Roof Technology in South-Central Texas  

E-Print Network (OSTI)

Early green roof cooling and energy reduction research in North America took place in Canada and the northern latitudes of the United States, where green roofs reduced rooftop temperatures by 70% to 90%. Less is known about green roof technology in the southern Untied States; where energy demand for cooling buildings is high, and the urban heat island effect is more pronounced. This paper reports early findings for rooftop membrane temperature reductions from 11.6-cm-deep modular green roof trays, typical of large-scaled, low-maintenance applications. Measurements observed during May, 2010 reveal that temperatures below the modular planted green roof units were 82% to 91.6% cooler compared to the surface temperatures of the control roof membrane. These findings on low-input modular green roof trays reinforce other research findings that indicate green roof technology can dramatically reduce and modify temperatures on roof deck surfaces during peak energy demand periods in hot sunny climates.

Measuring mine roof bolt strains  

DOE Patents (OSTI)

A mine roof bolt and a method of measuring the strain in mine roof bolts of this type are disclosed. According to the method, a flat portion on the head of the mine roof bolt is first machined. Next, a hole is drilled radially through the bolt at a predetermined distance from the bolt head. After installation of the mine roof bolt and loading, the strain of the mine roof bolt is measured by generating an ultrasonic pulse at the flat portion. The time of travel of the ultrasonic pulse reflected from the hole is measured. This time of travel is a function of the distance from the flat portion to the hole and increases as the bolt is loaded. Consequently, the time measurement is correlated to the strain in the bolt. Compensation for various factors affecting the travel time are also provided.

Some cadmium sulfite solar cells and silicon solar cells are being tested as potential future roofing panels. Graphs showing the temperature variation of each material versus testing time are given for a heating and a cooling cycle. The environmental conditions of testing such as: solar insolation, apparent sky temperature, ambient air temperature, relative humidity and wind speed are also given. On the basis of preliminary results obtained during the testing of roofing materials, several mini-modules of an integrated collector/radiator/ roof element with the dimensions 0.6 m x 0.6 m (2 ft x 2 ft) were constructed and tested. The thermal response of the mini-modules under solar and nocturnal sky radiation is shown and the testing results are discussed. The spectral transmittance curves for nine transparent cover materials are also presented. The preliminary results indicate that solar radiation and nocturnal sky radiation could be used effectively by employing an integrated collector/radiator structure.

Pierce Digital Communications Specialist, Office of Public Affairs Lately, I've been hearing a lot about cool roof technologies, so I welcomed the chance to learn more at a recent seminar. Cool roofs, also referred to as white roofs, have special coatings that reflect sunlight and emit heat more efficiently than traditional roofs, keeping them cooler in the sun. Cool roofing technologies can be implemented quickly and at a relatively low cost, making it the fastest growing sector of the building industry. U.S. Department of Energy Secretary Steven Chu is among the many cool roof enthusiasts. The Secretary recently announced plans to install cool roofs

Advanced Energy Efficient Roof System  

SciTech Connect

Energy consumption in buildings represents 40 percent of primary U.S. energy consumption, split almost equally between residential (22%) and commercial (18%) buildings.1 Space heating (31%) and cooling (12%) account for approximately 9 quadrillion Btu. Improvements in the building envelope can have a significant impact on reducing energy consumption. Thermal losses (or gains) from the roof make up 14 percent of the building component energy load. Infiltration through the building envelope, including the roof, accounts for an additional 28 percent of the heating loads and 16 percent of the cooling loads. These figures provide a strong incentive to develop and implement more energy efficient roof systems. The roof is perhaps the most challenging component of the building envelope to change for many reasons. The engineered roof truss, which has been around since 1956, is relatively low cost and is the industry standard. The roof has multiple functions. A typical wood frame home lasts a long time. Building codes vary across the country. Customer and trade acceptance of new building products and materials may impede market penetration. The energy savings of a new roof system must be balanced with other requirements such as first and life-cycle costs, durability, appearance, and ease of construction. Conventional residential roof construction utilizes closely spaced roof trusses supporting a layer of sheathing and roofing materials. Gypsum board is typically attached to the lower chord of the trusses forming the finished ceiling for the occupied space. Often in warmer climates, the HVAC system and ducts are placed in the unconditioned and otherwise unusable attic. High temperature differentials and leaky ducts result in thermal losses. Penetrations through the ceilings are notoriously difficult to seal and lead to moisture and air infiltration. These issues all contribute to greater energy use and have led builders to consider construction of a conditioned attic. The options considered to date are not ideal. One approach is to insulate between the trusses at the roof plane. The construction process is time consuming and costs more than conventional attic construction. Moreover, the problems of air infiltration and thermal bridges across the insulation remain. Another approach is to use structurally insulated panels (SIPs), but conventional SIPs are unlikely to be the ultimate solution because an additional underlying support structure is required except for short spans. In addition, wood spline and metal locking joints can result in thermal bridges and gaps in the foam. This study undertook a more innovative approach to roof construction. The goal was to design and evaluate a modular energy efficient panelized roof system with the following attributes: (1) a conditioned and clear attic space for HVAC equipment and additional finished area in the attic; (2) manufactured panels that provide structure, insulation, and accommodate a variety of roofing materials; (3) panels that require support only at the ends; (4) optimal energy performance by minimizing thermal bridging and air infiltration; (5) minimal risk of moisture problems; (6) minimum 50-year life; (7) applicable to a range of house styles, climates and conditions; (8) easy erection in the field; (9) the option to incorporate factory-installed solar systems into the panel; and (10) lowest possible cost. A nationwide market study shows there is a defined market opportunity for such a panelized roof system with production and semi-custom builders in the United States. Senior personnel at top builders expressed interest in the performance attributes and indicate long-term opportunity exists if the system can deliver a clear value proposition. Specifically, builders are interested in (1) reducing construction cycle time (cost) and (2) offering increased energy efficiency to the homebuyer. Additional living space under the roof panels is another low-cost asset identified as part of the study. The market potential is enhanced through construction activity levels in target marke

Evaluation of Vegetative Roofs' Performance on Energy Consumption in Hot and Humid Climates  

E-Print Network (OSTI)

Green roofs have been widely used in Europe proved to be beneficial. However, in the US they are not widespread. Previous studies have concluded that the main obstacle that makes architects, developers, etc. reluctant to introduce vegetative roofs is their preference for the traditional roofing since it is a tried-and-true technology. A positive feedback on the performance of vegetative roofs will encourage developers and possibly government authorities to invest more in them. Therefore, a survey was conducted to determine the performance of green roofs in existing buildings in hot and humid climates. This paper presents the results of this survey of around 40 buildings. The methodology and pertinent questions are also presented. Due to the many parameters involved in determining the rate of energy consumption in a building, a definite conclusion regarding how much exactly they can effect on saving can not be drawn, however, the results showed that green roofs can result in saving in the annual energy consumption and using shrubs as well as increasing soil thickness were found to be most effective in reducing building energy consumption.

One Cool Roof One Cool Roof One Cool Roof November 9, 2010 - 10:28am Addthis Deputy Director Salmon Deputy Director, Resource Management The Office of Science occupies many buildings around the country, but it owns only two of them. One of them is making some news. The 134,629 sq. ft. (about 3 acres) roof of the Office of Scientific and Technical Information (OSTI) building in Oak Ridge, Tennessee is now officially a "Cool Roof" -- making it energy efficient in ways that darker roofs are not. Cool roofs are light in color, and therefore, reflect rather than absorb sunlight. The previous roof was black, but worse, it was leaky and those leaks, controlled for years in some very innovative ways by the OSTI staff, were going to cause significant problems if not addressed.

Passive solar roof ice melter  

Science Conference Proceedings (OSTI)

An elongated passive solar roof ice melter is placed on top of accumulated ice and snow including an ice dam along the lower edge of a roof of a heated building and is held against longitudinal movement with respect to itself. The melter includes a bottom wall having an upper surface highly absorbent to radiant solar energy; a first window situated at right angles with respect to the bottom wall, and a reflecting wall connecting the opposite side edges of the bottom wall and the first window. The reflecting wall has a surface facing the bottom wall and the window which is highly reflective to radiant solar energy. Radiant solar energy passes through the first window and either strikes the highly absorbent upper surface of the bottom wall or first strikes the reflecting wall to be reflected down to the upper surface of the bottom wall. The heat generated thereby melts through the ice below the bottom wall causing the ice dam to be removed between the bottom wall and the top of the roof and immediately adjacent to the ice melter along the roof. Water dammed up by the ice dam can then flow down through this break in the dam and drain out harmlessly onto the ground. This prevents dammed water from seeping back under the shingles and into the house to damage the interior of the house.

Evaluation of Roof Bolting Requirements Based on In-Mine Roof Bolter Drilling  

SciTech Connect

Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded deposits such as coal. In fact, all U.S. underground coal mine entries are roof-bolted as required by law. However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in real time during roof bolting operation. Based on this information, roof bolting design criteria for modern roof bolting systems will be developed for implementation in real time. For the prediction of roof geology and stability condition in real time, a micro processor was used and a program developed to monitor and record the drilling parameters of roof bolter. These parameters include feed pressure, feed flow (penetration rate), rotation pressure, rotation rate, vacuum pressure, oil temperature of hydraulic circuit, and signals for controlling machine. From the results of a series of laboratory and underground tests so far, feed pressure is found to be a good indicator for identifying the voids/fractures and estimating the roof rock strength. The method for determining quantitatively the location and the size of void/fracture and estimating the roof rock strength from the drilling parameters of roof bolter was developed. Also, a set of computational rules has been developed for in-mine roof using measured roof drilling parameters and implemented in MRGIS (Mine Roof Geology Information System), a software package developed to allow mine engineers to make use of the large amount of roof drilling parameters for predicting roof geology properties automatically. For the development of roof bolting criteria, finite element models were developed for tensioned and fully grouted bolting designs. Numerical simulations were performed to investigate the mechanisms of modern roof bolting systems including both the tension and fully grouted bolts. Parameters to be studied are: bolt length, bolt spacing, bolt size/strength, grout annulus, in-situ stress condition, overburden depth, and roof geology (massive strata, fractured, and laminated or thinly-bedded). Based on the analysis of the mechanisms of both bolting systems and failure modes of the bolted strata, roof bolting design criteria and programs for modern roof bolting systems were developed. These criterion and/or programs were combined with the MRGIS for use in conjunction with roof bolt installation.

As it turns out, the same principle works for roofs. Consider the results from a Lawrence Berkeley National Laboratory study in Austin, Texas, which measured a dark roof to average a whopping 43 degrees hotter than a light roof. The hotter the roof, the hotter the building becomes, and the more air-conditioning is needed - 11 percent, in that particular study. That in turn puts more carbon dioxide into the atmosphere. Higher atmospheric temperatures also affect atmospheric chemistry, causing higher ozone levels and more smog. Turning down the heat can be both inexpensive and simple, however: replace

Rain on the Roof-Evaporative Spray Roof Cooling  

E-Print Network (OSTI)

This paper describes evaporative spray roof cooling systems, their components, performance and applications in various climates and building types. The evolution of this indirect evaporative cooling technique is discussed. Psychrometric and sol-air principles are covered and a simplified method of evaluation presented. A life cycle energy savings example is discussed. Benefits of roof life and roof top equipment efficiency and maintenance are covered as well as water consumption and performance trade-offs with alternate methods of roof heat gain control. Testimonials and case studies are presented. The gradual migration of business, industry, and populace to the southern United States was largely brought on by the advent of the practical air-conditioner, cheap electricity, and the harshness of northern winters. But while "wintering at Palm Beach" has been replaced by "Sun Belt industries" ; the compression-refrigeration cooling cycle is about the only thing separating millions of southerners (native and adopted) from August heat stroke and the Detroit News employment ads. This migration has been spurred by economic recessions which hit harder at the competitively populated northern centers than at the still growing industries of the south. These trends are important illustrations of the concern for efficient cooling strategies. Not only are homes in hot climates vulnerable to the now not-so-low cost of electricity but large, compact. and heavily occupied buildings (offices, schools, hospitals, theaters, etc.) often must air-condition year-around. In 1968. air-conditioning was 3% of U.S. end energy consumption compared to 18% for space heating and 25% for transportation. By 1980, according to Electric Power Research Institute's Oliver Yu, air-conditioning use was 12.5% of all electricity generated and by the year 2000 is projected to reach 16.7% "as migration slows and the GNP reaches a stable 3% growth rate" (EPRI 1982 to 1986 Overview and Strategy). Of further significance is the effect of air-conditioning loads on the peak generating requirements of electrical utilities. Because utilities must build generating capacity to meet peak requirements, they normally charge a higher summer kWh rate (for residential) and levy a peak kW demand charge on a monthly or even annual "ratchet" rate (for larger service customers). The June '83 cover of Houston City Magazine, in reference to future electrical rates, promised: "Pay or Sweat". Typical of many cooling or heat gain prevention strategies being employed on "innovative" buildings in warm climates, evaporative spray roof cooling (ESRC) systems (not to be confused with roof ponds) are not new. Like ventilated structures, ice house roofs, enhanced ventilation, masonry walls, night sky radiation and ground contact cooling, evaporative cooling in many forms has been around for centuries. (See Solar Age, July '82 and February '81 for related articles). Even the development of roof spray systems is not as newly founded as one might suspect.

Science Conference Proceedings (OSTI)

Solar-reflective roofs remain cooler than absorptive roofs and thus conserve electricity otherwise needed for air conditioning. A currently controversial aspect of solar-reflective cool roofing is the extent to which an initially high solar reflectance decreases with time. We present experimental data on the spectral absorption of deposits that accumulate on roofs, and we attribute most of the absorption to carbon soot originally produced by combustion. The deposits absorb more at short wavelengths (e.g., in the blue) than in the red and infrared, imparting a slightly yellow tinge to formerly white surfaces. The initial rate of reflectance reduction by soot accumulation is consistent with known emission rates that are due to combustion. The long-term reflectance change appears to be determined by the ability of the soot to adhere to the roof, resisting washout by rain.

Cool Roof Calculator Cool Roof Calculator Cool Roof Calculator logo. Many reflective roof coatings and membranes are now available for low-slope roofs. These coatings help to reduce summer air-conditioning loads, but can also increase the winter heating load. The Cool Roof Calculator will estimate both how much energy you'll save in the summer and how much extra energy you'll need in the winter. Cool Roof Calculator provides answers on a 'per square foot' basis, so you can then multiply by the area of your roof to find out your net savings each year.

Modeling the effects of reflective roofing  

SciTech Connect

Roofing materials which are highly reflective to sunlight are currently being developed. Reflective roofing is an effective summertime energy saver in warm and sunny climates. It has been demonstrated to save up to 40% of the energy needed to cool a building during the summer months. Buildings without air conditioning can reduce their indoor temperatures and improve occupant comfort during the summer if highly reflective roofing materials are used. But there are questions about the tradeoff between summer energy savings and extra wintertime energy use due to reduced heat collection by the roof. These questions are being answered by simulating buildings in various climates using the DOE-2 program (version 2.1E). Unfortunately, DOE-2 does not accurately model radiative, convective and conductive processes in the roof-attic. Radiative heat transfer from the underside of a reflective roof is much smaller than that of a roof which absorbs heat from sunlight, and must be accounted for in the building energy model. Convection correlations for the attic and the roof surface must be fine tuned. An equation to model the insulation`s conductivity dependence on temperature must also be added. A function was written to incorporate the attic heat transfer processes into the DOE-2 building energy simulation. This function adds radiative, convective and conductive equations to the energy balance of the roof. Results of the enhanced DOE-2 model were compared to measured data collected from a school bungalow in a Sacramento Municipal Utility District monitoring project, with particular attention paid to the year-round energy effects.

Next Generation Roofs and Attics for Homes  

SciTech Connect

Prototype residential roof and attic assemblies were constructed and field tested in a mixed-humid U.S. climate. Summer field data showed that at peak day irradiance the heat transfer penetrating the roof deck dropped almost 90% compared with heat transfer for a conventional roof and attic assembly. The prototype assemblies use a combination of strategies: infrared reflective cool roofs, radiant barriers, above-sheathing ventilation, low-emittance surfaces, insulation, and thermal mass to reduce the attic air temperature and thus the heat transfer into the home. The prototype assemblies exhibited attic air temperatures that did not exceed the peak day outdoor air temperature. Field results were benchmarked against an attic computer tool and simulations made for the densely populated, hot and dry southeastern and central-basin regions of California. New construction in the central basin could realize a 12% drop in ceiling and air-conditioning annual load compared with a code-compliant roof and attic having solar reflectance of 0.25 and thermal emittance of 0.75. In the hot, dry southeastern region of California, the combined ceiling and duct annual load drops by 23% of that computed for a code-compliant roof and attic assembly. Eliminating air leakage from ducts placed in unconditioned attics yielded savings comparable to the best simulated roof and attic systems. Retrofitting an infrared reflective clay tile roof with 1 -in (0.032-m) of EPS foam above the sheathing and improving existing ductwork by reducing air leakage and wrapping ducts with insulation can yield annual savings of about $200 compared with energy costs for pre-1980 construction.

Low-slope roofing research needs: An ORNL draft assessment  

Science Conference Proceedings (OSTI)

The Low-Slope Roofing Research Needs Agenda is a resource document prepared by the Roofing Industry Research Advisory Panel. The document will aid the Panel in developing recommended research priorities and schedules for the Roof Research Center established by the US Department of Energy at Oak Ridge National Laboratory (ORNL). The Roof Research Center provides the roofing industry with a unique test facility capable of careful, on-line measurements on whole roof systems under controlled, simulated in-service conditions. This type of systems testing, however, is not well-developed in the roofing industry where, customarily, careful measurements are not only made to assess individual material properties under design conditions and systems testing generally is limited to ''performance testing''; that is, exposing roof systems to typical or accelerated environments and observing or measuring the time intergrated effects on various components. This document discusses the capabilities of the center and roofing research issues.

Weathering of Roofing Materials-An Overview  

Science Conference Proceedings (OSTI)

An overview of several aspects of the weathering of roofing materials is presented. Degradation of materials initiated by ultraviolet radiation is discussed for plastics used in roofing, as well as wood and asphalt. Elevated temperatures accelerate many deleterious chemical reactions and hasten diffusion of material components. Effects of moisture include decay of wood, acceleration of corrosion of metals, staining of clay, and freeze-thaw damage. Soiling of roofing materials causes objectionable stains and reduces the solar reflectance of reflective materials. (Soiling of non-reflective materials can also increase solar reflectance.) Soiling can be attributed to biological growth (e.g., cyanobacteria, fungi, algae), deposits of organic and mineral particles, and to the accumulation of flyash, hydrocarbons and soot from combustion.

A cooler roof means energy bills that are up to 10-15% lower because your air conditioner doesn't have to work as hard. Check out Google Earth - the 'view from above' of your favorite American city. And look at the roofs of the office buildings, warehouses, shopping centers, and even the homes.

Evolution of cool-roof standards in the United States  

SciTech Connect

Roofs that have high solar reflectance and high thermal emittance stay cool in the sun. A roof with lower thermal emittance but exceptionally high solar reflectance can also stay cool in the sun. Substituting a cool roof for a noncool roof decreases cooling-electricity use, cooling-power demand, and cooling-equipment capacity requirements, while slightly increasing heating-energy consumption. Cool roofs can also lower citywide ambient air temperature in summer, slowing ozone formation and increasing human comfort. Provisions for cool roofs in energy-efficiency standards can promote the building- and climate-appropriate use of cool roofing technologies. Cool-roof requirements are designed to reduce building energy use, while energy-neutral cool-roof credits permit the use of less energy-efficient components (e.g., larger windows) in a building that has energy-saving cool roofs. Both types of measures can reduce the life-cycle cost of a building (initial cost plus lifetime energy cost). Since 1999, several widely used building energy-efficiency standards, including ASHRAE 90.1, ASHRAE 90.2, the International Energy Conservation Code, and California's Title 24 have adopted cool-roof credits or requirements. This paper reviews the technical development of cool-roof provisions in the ASHRAE 90.1, ASHRAE 90.2, and California Title 24 standards, and discusses the treatment of cool roofs in other standards and energy-efficiency programs. The techniques used to develop the ASHRAE and Title 24 cool-roof provisions can be used as models to address cool roofs in building energy-efficiency standards worldwide.

A novel technique for the production of cool colored concrete tile and asphalt shingle roofing products  

SciTech Connect

The widespread use of solar-reflective roofing materials can save energy, mitigate urban heat islands and slow global warming by cooling the roughly 20% of the urban surface that is roofed. In this study we created prototype solar-reflective nonwhite concrete tile and asphalt shingle roofing materials using a two-layer spray coating process intended to maximize both solar reflectance and factory-line throughput. Each layer is a thin, quick-drying, pigmented latex paint based on either acrylic or a poly(vinylidene fluoride)/acrylic blend. The first layer is a titanium dioxide rutile white basecoat that increases the solar reflectance of a gray-cement concrete tile from 0.18 to 0.79, and that of a shingle surfaced with bare granules from 0.06 to 0.62. The second layer is a 'cool' color topcoat with weak near-infrared (NIR) absorption and/or strong NIR backscattering. Each layer dries within seconds, potentially allowing a factory line to pass first under the white spray, then under the color spray. We combined a white basecoat with monocolor topcoats in various shades of red, brown, green and blue to prepare 24 cool color prototype tiles and 24 cool color prototypes shingles. The solar reflectances of the tiles ranged from 0.26 (dark brown; CIELAB lightness value L* = 29) to 0.57 (light green; L* = 76); those of the shingles ranged from 0.18 (dark brown; L* = 26) to 0.34 (light green; L* = 68). Over half of the tiles had a solar reflectance of at least 0.40, and over half of the shingles had a solar reflectance of at least 0.25.

Aging and weathering of cool roofing membranes  

Science Conference Proceedings (OSTI)

Aging and weathering can reduce the solar reflectance of cool roofing materials. This paper summarizes laboratory measurements of the solar spectral reflectance of unweathered, weathered, and cleaned samples collected from single-ply roofing membranes at various sites across the United States. Fifteen samples were examined in each of the following six conditions: unweathered; weathered; weathered and brushed; weathered, brushed and then rinsed with water; weathered, brushed, rinsed with water, and then washed with soap and water; and weathered, brushed, rinsed with water, washed with soap and water, and then washed with an algaecide. Another 25 samples from 25 roofs across the United States and Canada were measured in their unweathered state, weathered, and weathered and wiped. We document reduction in reflectivity resulted from various soiling mechanisms and provide data on the effectiveness of various cleaning approaches. Results indicate that although the majority of samples after being washed with detergent could be brought to within 90% of their unweathered reflectivity, in some instances an algaecide was required to restore this level of reflectivity.

Cool roofs as an energy conservation measure for federal buildings  

SciTech Connect

We have developed initial estimates of the potential benefits of cool roofs on federal buildings and facilities (building scale) as well as extrapolated the results to all national facilities under the administration of the Federal Energy Management Program (FEMP). In addition, a spreadsheet ''calculator'' is devised to help FEMP estimate potential energy and cost savings of cool roof projects. Based on calculations for an average insulation level of R-11 for roofs, it is estimated that nationwide annual savings in energy costs will amount to $16M and $32M for two scenarios of increased roof albedo (moderate and high increases), respectively. These savings, corresponding to about 3.8 percent and 7.5 percent of the base energy costs for FEMP facilities, include the increased heating energy use (penalties) in winter. To keep the cost of conserved energy (CCE) under $0.08 kWh-1 as a nationwide average, the calculations suggest that the incremental cost for cool roofs should not exceed $0.06 ft-2, assuming that cool roofs have the same life span as their non-cool counterparts. However, cool roofs usually have extended life spans, e.g., 15-30 years versus 10 years for conventional roofs, and if the costs of re-roofing are also factored in, the cutoff incremental cost to keep CCE under $0.08 kWh-1 can be much higher. In between these two ends, there is of course a range of various combinations and options.

Visual Analytics for Roof Savings Calculator Ensembles  

SciTech Connect

The Roof Savings Calculator (RSC) has been deployed for DOE as an industry-consensus, web-based tool for easily running complex building energy simulations. These simulations allow both homeowners and experts to determine building-specific cost and energy savings for modern roof and attic technologies. Using a database of over 3 million RSC simulations for different combinations of parameters, we have built a visual analytics tool to assist in the exploration and identification of features in the data. Since the database contains multiple variables, both categorical and continuous, we employ a coordinated multi-view approach that allows coordinated feature exploration through multiple visualizations at once. The main component of our system, a parallel coordinates view, has been adapted to handle large-scale, mixed data types as are found in RSC simulations. Other visualizations include map coordinated plots, high dynamic range (HDR) line plot rendering, and an intuitive user interface. We demonstrate these techniques with several use cases that have helped identify software and parametric simulation issues.

Evaporative Roof Cooling - A Simple Solution to Cut Cooling Costs  

E-Print Network (OSTI)

Since the "Energy Crisis" Evaporative Roof Cooling Systems have gained increased acceptance as a cost effective method to reduce the high cost of air conditioning. Documented case histories in retrofit installations show direct energy savings and paybacks from twelve to thirty months. The main operating cost of an Evaporative Roof Cooling System is water. One thousand gallons of water, completely evaporated, will produce over 700 tons of cooling capability. Water usage seldom averages over 100 gallons per 1000 ft^2 of roof area per day or 10 oz. of water per 100 ft^2 every six minutes. Roof Cooling Systems, when planned in new construction, return 1-1/2 times the investment the first year in equipment savings and operating costs. Roof sprays are a low cost cooling solution for warehouses, distribution centers and light manufacturing or assembly areas with light internal loads. See text "Flywheel Cooling."

Effectiveness of Cool Roof Coatings with Ceramic Particles  

SciTech Connect

Liquid applied coatings promoted as cool roof coatings, including several with ceramic particles, were tested at Oak Ridge National Laboratory (ORNL), Oak Ridge, Tenn., for the purpose of quantifying their thermal performances. Solar reflectance measurements were made for new samples and aged samples using a portable reflectometer (ASTM C1549, Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer) and for new samples using the integrating spheres method (ASTM E903, Standard Test Method for Solar Absorptance, Reflectance, and Transmittance of Materials Using Integrating Spheres). Thermal emittance was measured for the new samples using a portable emissometer (ASTM C1371, Standard Test Method for Determination of Emittance of Materials Near Room 1 Proceedings of the 2011 International Roofing Symposium Temperature Using Portable Emissometers). Thermal conductivity of the coatings was measured using a FOX 304 heat flow meter (ASTM C518, Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus). The surface properties of the cool roof coatings had higher solar reflectance than the reference black and white material, but there were no significant differences among coatings with and without ceramics. The coatings were applied to EPDM (ethylene propylene diene monomer) membranes and installed on the Roof Thermal Research Apparatus (RTRA), an instrumented facility at ORNL for testing roofs. Roof temperatures and heat flux through the roof were obtained for a year of exposure in east Tennessee. The field tests showed significant reduction in cooling required compared with the black reference roof (~80 percent) and a modest reduction in cooling compared with the white reference roof (~33 percent). The coating material with the highest solar reflectivity (no ceramic particles) demonstrated the best overall thermal performance (combination of reducing the cooling load cost and not incurring a large heating penalty cost) and suggests solar reflectivity is the significant characteristic for selecting cool roof coatings.

Flexible shaft and roof drilling system  

DOE Patents (OSTI)

A system for drilling holes in the roof of a mine has a flexible shaft with a pair of oppositely wound, coaxial flat bands. One of the flat bands defines an inner spring that is wound right handed into a helical configuration, adjacent convolutions being in nesting relationship to one another. The other flat band defines an outer spring that is wound left handed into a helical configuration about the inner band, adjacent convolutions being nesting relationship with one another. A transition member that is configured to hold a rock bit is mounted to one end of the flexible shaft. When torque and thrust are applied to the flexible shaft by a driver, the inner spring expands outwardly and the outer spring contracts inwardly to form a relatively rigid shaft.

Inclusion of cool roofs in nonresidential Title 24 prescriptive requirements  

SciTech Connect

Roofs that have high solar reflectance (high ability to reflect sunlight) and high thermal emittance (high ability to radiate heat) tend to stay cool in the sun. The same is true of low-emittance roofs with exceptionally high solar reflectance. Substituting a cool roof for a noncool roof tends to decrease cooling electricity use, cooling power demand, and cooling-equipment capacity requirements, while slightly increasing heating energy consumption. Cool roofs can also lower the ambient air temperature in summer, slowing ozone formation and increasing human comfort. DOE-2.1E building energy simulations indicate that use of a cool roofing material on a prototypical California nonresidential building with a low-sloped roof yields average annual cooling energy savings of approximately 300 kWh/1000 ft2 [3.2 kWh/m2], average annual natural gas deficits of 4.9 therm/1000 ft2 [5.6 MJ/m2], average source energy savings of 2.6 MBTU/1000 ft2 [30 MJ/m2], and average peak power demand savings of 0. 19 kW/1000 ft2 [2.1 W/m2]. The 15-year net present value (NPV) of energy savings averages $450/1000 ft2 [$4.90/m2] with time dependent valuation (TDV), and $370/1000 ft2 [$4.00/m2] without TDV. When cost savings from downsizing cooling equipment are included, the average total savings (15-year NPV + equipment savings) rises to $550/1000 ft2 [$5.90/m2] with TDV, and to $470/1000 ft2 [$5.00/m2] without TDV. Total savings range from 0.18 to 0.77 $/ft2 [1.90 to 8.30 $/m2] with TDV, and from 0.16 to 0.66 $/ft2 [1.70 to 7.10 $/m2] without TDV, across California's 16 climate zones. The typical cost premium for a cool roof is 0.00 to 0.20 $/ft2 [0.00 to 2.20 $/m2]. Cool roofs with premiums up to $0.20/ft2 [$2.20/m2] are expected to be cost effective in climate zones 2 through 16; those with premiums not exceeding $0.18/ft2 [$1.90/m2] are expected to be also cost effective in climate zone 1. Hence, this study recommends that the year-2005 California building energy efficiency code (Title 24, Pa rt 6 of the California Code of Regulations) for nonresidential buildings with low-sloped roofs include a cool-roof prescriptive requirement in all California climate zones. Buildings with roofs that do not meet prescriptive requirements may comply with the code via an ''overall-envelope'' approach (non-metal roofs only), or via a performance approach (all roof types).

cool roofs on commercial buildings: conserving cool roofs on commercial buildings: conserving energy, saving money, and reducing emission of greenhouse gases and air pollutants Title Potential benefits of cool roofs on commercial buildings: conserving energy, saving money, and reducing emission of greenhouse gases and air pollutants Publication Type Journal Article Year of Publication 2010 Authors Levinson, Ronnen M., and Hashem Akbari Journal Energy Efficiency Volume 3 Pagination 53-109 Publisher Springer Netherlands ISSN 1570-646X Keywords cool roof, Heat Island Abstract Cool roofs-roofs that stay cool in the sun by minimizing solar absorption and maximizing thermal emission-lessen the flow of heat from the roof into the building, reducing the need for space cooling energy in conditioned buildings. Cool roofs may also increase the need for heating energy in cold climates. For a commercial building, the decrease in annual cooling load is typically much greater than the increase in annual heating load. This study combines building energy simulations, local energy prices, local electricity emission factors, and local estimates of building density to characterize local, state average, and national average cooling energy savings, heating energy penalties, energy cost savings, and emission reductions per unit conditioned roof area. The annual heating and cooling energy uses of four commercial building prototypes-new office (1980+), old office (pre-1980), new retail (1980+), and old retail (pre-1980)-were simulated in 236 US cities. Substituting a weathered cool white roof (solar reflectance 0.55) for a weathered conventional gray roof (solar reflectance 0.20) yielded annually a cooling energy saving per unit conditioned roof area ranging from 3.30 kWh/m2 in Alaska to 7.69 kWh/m2 in Arizona (5.02 kWh/m2 nationwide); a heating energy penalty ranging from 0.003 therm/m2 in Hawaii to 0.14 therm/m2 in Wyoming (0.065 therm/m2 nationwide); and an energy cost saving ranging from $0.126/m2 in West Virginia to $1.14/m2 in Arizona ($0.356/m2 nationwide). It also offered annually a CO2 reduction ranging from 1.07 kg/m2 in Alaska to 4.97 kg/m2 in Hawaii (3.02 kg/m2 nationwide); an NOx reduction ranging from 1.70 g/m2 in New York to 11.7 g/m2 in Hawaii (4.81 g/m2 nationwide); an SO2 reduction ranging from 1.79 g/m2 in California to 26.1 g/m2 in Alabama (12.4 g/m2 nationwide); and an Hg reduction ranging from 1.08 μg/m2 in Alaska to 105 μg/m2 in Alabama (61.2 μg/m2 nationwide). Retrofitting 80% of the 2.58 billion square meters of commercial building conditioned roof area in the USA would yield an annual cooling energy saving of 10.4 TWh; an annual heating energy penalty of 133 million therms; and an annual energy cost saving of $735 million. It would also offer an annual CO2 reduction of 6.23 Mt, offsetting the annual CO2 emissions of 1.20 million typical cars or 25.4 typical peak power plants; an annual NOx reduction of 9.93 kt, offsetting the annual NOx emissions of 0.57 million cars or 65.7 peak power plants; an annual SO2 reduction of 25.6 kt, offsetting the annual SO2 emissions of 815 peak power plants; and an annual Hg reduction of 126 kg.

Top-of-atmosphere radiative cooling with white roofs: experimental Top-of-atmosphere radiative cooling with white roofs: experimental verification and model-based evaluation Title Top-of-atmosphere radiative cooling with white roofs: experimental verification and model-based evaluation Publication Type Journal Article Year of Publication 2012 Authors Salamanca, Francisco, Shaheen R. Tonse, Surabi Menon, Vishal Garg, Krishna P. Singh, Manish Naja, and Marc L. Fischer Journal Environmental Research Letters Volume 7 Issue 4 Abstract We evaluate differences in clear-sky upwelling shortwave radiation reaching the top of the atmosphere in response to increasing the albedo of roof surfaces in an area of India with moderately high aerosol loading. Treated (painted white) and untreated (unpainted) roofs on two buildings in northeast India were analyzed on five cloudless days using radiometric imagery from the IKONOS satellite. Comparison of a radiative transfer model (RRTMG) and radiometric satellite observations shows good agreement (R2 = 0.927). Results show a mean increase of ~50 W m-2 outgoing at the top of the atmosphere for each 0.1 increase of the albedo at the time of the observations and a strong dependence on atmospheric transmissivity.

Analytical study of residential building with reflecting roofs  

SciTech Connect

This report presents an analysis of the effect of roof solar reflectance on the annual heating (cooling) loads, peak heating (cooling) loads, and roof temperatures of the residential buildings. The annual heating (cooling) loads, peak heating (cooling) loads, and exterior roof temperatures for a small compact ranch house are computed using the Thermal Analysis Research Program (TARP). The residential models, with minor modifications in the thermal envelope for different locations, are subjected to hourly weather data for one year compiled in the Weather Year for Energy Calculation (WYEC) for in the following locations: Birmingham, Alabama; Bismarck, North Dakota; Miami, Florida; Phoenix, Arizona; Portland, Maine; and, Washington, D.C. Building loads have been determined for a full factorial experimental design that varies the following parameters of the residential model: solar reflectance of the roof, ceiling thermal resistance, attic ventilation, and attic mass framing area. The computed results for annual heating (cooling) loads and peak heating (cooling) loads are illustrated graphically, both globally for all cities and locally for each geographic location. The effect of peak parameter is ranked (highest to lowest) for effect on annual heating and cooling loads, and peak heating and cooling loads. A parametric study plots the building loads as a function of roof solar reflectance for different levels of ceiling thermal resistances and for each geographic location.

Plain Talk About Condensation and Radiation Below Metal Roof Assemblies  

E-Print Network (OSTI)

During recent decades an increasing number of users have chosen metal roofing for various commercial, industrial and institutional buildings. Because of several advantages, construction of new pre-engineered and "hybrid" buildings has outpaced low-rise, nonresidential conventional construction since 1984. Unfortunately, some of these advantages may give rise to certain disadvantages in comfort, durability and operating costs (7). This paper provides a brief historical overview of common metal roof insulation methods as well as recent innovations for low cost/no cost performance enhancements. Following is a discussion of current industry trends and design considerations for those seeking to control the combined effects of conduction, convection, radiation and moisture migration in individual roof assemblies.

Preliminary Analysis of Energy Consumption for Cool Roofing Measures  

SciTech Connect

The spread of cool roofing has been more than prolific over the last decade. Driven by public demand and by government initiatives cool roofing has been a recognized low cost method to reduce energy demand by reflecting sunlight away from structures and back in to the atmosphere. While much of the country can benefit from the use of cool coatings it remains to be seen whether the energy savings described are appropriate in cooler climates. By use of commonly available calculators one can analyze the potential energy savings based on environmental conditions and construction practices.

Sustainable Retrofit of Residential Roofs Using Metal Roofing Panels, Thin-Film Photovoltaic Laminates, and PCM Heat Sink Technology  

DOE Green Energy (OSTI)

During September-October 2009, research teams representing Metal Construction Association (the largest North American trade association representing metal building manufacturers, builders, and material suppliers), CertainTeed (one of the largest U.S. manufacturers of thermal insulation and building envelope materials), Unisolar (largest U.S. producer of amorphous silicone photo-voltaic (PV) laminates), Phase Change Energy (manufacturer of bio-based PCM), and Oak Ridge National Laboratory (ORNL) installed three experimental attics utilizing different roof retrofit strategies in the ORNL campus. The main goal of this project was experimental evaluation of a newly-developed sustainable re-roofing technology utilizing amorphous silicone PV laminates integrated with metal roof and PCM heat sink. The experimental attic with PV laminate was expected to work during the winter time as a passive solar collector with PCM storing solar heat, absorbed during the day, and increasing overall attic air temperature during the night.

Cool roofs can also lower citywideambient air temperature in summer, slowing ozone formation and increasinghuman comfort.DOE-2.1E building energy simulations indicate that use of acool roofing material on a prototypical California nonresidential (NR)building with a low-sloped roof yields average annual cooling energysavings of approximately 3.2 kW h/m2 (300 kW h/1000 ft2), average annualnatural gas deficits of 5.6 MJ/m2 (4.9 therm/1000 ft2), average annualsource energy savings of 30 MJ/m2 (2.6 MBTU/1000 ft2), and average peakpower demand savings of 2.1 W/m2 (0.19 kW/1000 ft2). The 15-year netpresent value (NPV) of energy savings averages $4.90/m2 ($450/1000 ft2)with time-dependent valuation (TDV), and $4.00/m2 ($370/1000 ft2) withoutTDV. When cost savings from downsizing cooling equipment are included,the average total savings (15-year NPV+equipment savings) rises to$5.90/m2 ($550/1000 ft2) with TDV, and to $5.00/m2 ($470/1000 ft2)without TDV.Total savings range from 1.90 to 8.30 $/m2 (0.18 0.77 $/ft2)with TDV, and from 1.70 to 7.10 $/m2 (0.16 0.66 $/ft2) without TDV,across California's 16 climate zones. The typical cost premium for a coolroof is 0.00 2.20 $/m2 (0.00 0.20 $/ft2). Cool roofs with premiums up to$2.20/m2 ($0.20/ft2) are expected to be cost effective in climate zones 216; those with premiums not exceeding $1.90/m2 ($0.18/ft2) are expectedto be also cost effective in climate zone 1. Hence, this study recommendsthat the year-2005 California building energy efficiency code (Title 24,Part 6 of the California Code of Regulations) for NR buildings withlow-sloped roofs include a cool-roof prescriptive requirement in allCalifornia climate zones. Buildings with roofs that do not meetprescriptive requirements may comply with the code via an"overall-envelope" approach (non-metal roofs only), or via a performanceapproach (all roof types).

A whole building demonstration of re-cover over an existing wet roof  

SciTech Connect

Roof re-cover, the practice of installing a new roof over an existing failed roof, has become commonplace. The 1994 National Roofing Contractors Annual Roofing Survey reported that approximately 33% of current reroofing activity is re-cover. Market trends suggest that re-cover will become an increasingly more popular option. Moisture in the failed roof complicates the decision whether or not to re-cover and how to do the recover if that is the decision. If the root to be re-covered contains moisture that will not be removed during reroofing, this moisture must be able to escape from the roof system. Otherwise, moisture entrapped in the roofing system may eventually lead to the mechanical failure of fasteners and the roof deck, especially if it is metal. In 1991, the Oak Ridge National Laboratory (ORNL) surveyed its own roofing inventory and found that 164 buildings or 70% of the laboratory roof area needed reroofing. Because of the high cost of tear off and replacement, an alterative was sought. This paper describes the procedure employed to determine the suitability of a particular roof system on a laboratory building for re-covering. The procedure involves the use of field diagnostics, laboratory experiments and numerical simulations that demonstrate that the particular roof type can be re-covered. Furthermore, the building and roof system have been monitored for approximately 16 months after re-cover. The monitoring results are compared to the numerical simulations and demonstrate that the roof system is drying and that the reroofing strategy that they used is cost-effective.

Load test of the 277W Building high bay roof deck and support structure  

SciTech Connect

The 277W Building high bay roof area was load tested according to the approved load-test procedure, WHC-SD-GN-TP-30015, Revision 1. The 277W Building is located in the 200 West Area of the Hanford Site and has the following characteristics: roof deck -- wood decking supported by 4 x 14 timber purlins; roof membrane -- tar and gravel; roof slope -- flat (<10 deg); and roof elevation -- maximum height of about 63 ft. The 227W Building was visited in March 1994 for a visual inspection. During this inspection, cracked areas were visible in the decking, but it was not possible to determine whether these cracks extended completely through the decking, which is 2-in. thick. The building was revisited in March 1994 for the purpose of writing this test report. Because the roof requires personnel access, a test was determined to be the best way to qualify the roof. The conclusions are that the roof has been qualified for 500-lb total roof load and that the ``No Roof Access`` signs can be changed to ``Roof Access Restricted`` signs.

A Review of Methods for the Manufacture of Residential RoofingMaterials  

DOE Green Energy (OSTI)

Shingles, tiles, and metal products comprise over 80% (by roof area) of the California roofing market (54-58% fiberglass shingle, 8-10% concrete tile, 8-10% clay tile, 7% metal, 3% wood shake, and 3% slate). In climates with significant demand for cooling energy, increasing roof solar reflectance reduces energy consumption in mechanically cooled buildings, and improves occupant comfort in non-conditioned buildings. This report examines methods for manufacturing fiberglass shingles, concrete tiles, clay tiles, and metal roofing. The report also discusses innovative methods for increasing the solar reflectance of these roofing materials. We have focused on these four roofing products because they are typically colored with pigmented coatings or additives. A better understanding of the current practices for manufacturing colored roofing materials would allow us to develop cool colored materials creatively and more effectively.

The Equivalent Thermal Resistance of Tile Roofs with and without Batten Systems  

Science Conference Proceedings (OSTI)

Clay and concrete tile roofs were installed on a fully instrumented attic test facility operating in East Tennessee s climate. Roof, attic and deck temperatures and heat flows were recorded for each of the tile roofs and also on an adjacent attic cavity covered with a conventionally pigmented and direct-nailed asphalt shingle roof. The data were used to benchmark a computer tool for simulation of roofs and attics and the tool used to develop an approach for computing an equivalent seasonal R-value for sub-tile venting. The approach computed equal heat fluxes through the ceilings of roofs having different combinations of surface radiation properties and or building constructions. A direct nailed shingle roof served as a control for estimating the equivalent thermal resistance of the air space. Simulations were benchmarked to data in the ASHRAE Fundamentals for the thermal resistance of inclined and closed air spaces.

Comparative Summer Thermal Performance of Finished and Unfinished Metal Roofing Products with Composition Shingles  

E-Print Network (OSTI)

This paper presents an overview of results from experimental research conducted at FSEC's Flexible Roofing Facility in the summer of 2002. The Flexible Roof Facility (FRF) is a test facility in Cocoa, Florida designed to evaluate a combination of five roofing systems against a control roof using dark shingles. The intent of the testing is to evaluate how roofing systems impact residential cooling energy use. Recent testing emphasizes evaluation of how increasingly popular metal roofing systems, both finished and unfinished, might compare with other more traditional roofing types. All of the test cells had R-19 insulation installed on the attic floor except in the double roof configuration which had R-19 of open cell foam blown onto the underside of the roof decking. The test results were used to determine relative thermal performance of various roofing systems under typical Florida summer conditions. Measured impacts included changes to ceiling heat flux and attic air temperature which influences loads from unintended attic air leakage and duct heat gain. We also develop an analysis method to estimate total cooling energy benefits of different roofing systems considering the various impacts. The results show that all the options perform better than dark composition shingles. White metal performs best with an estimated cooling energy reduction of about 15%, but the spectrally selective metal shingles (12%) and unfinished Galvalume roofs (11%) do surprisingly well. Galvanized roofing did less well than Galvalume (7% reduction) and worse performance in the second year of exposure was observed due to corrosion of the zinc surface. The sealed attic with a double roof produced an estimated cooling energy reduction of only 2% -- largely due to increases in ceiling flux.

Measured energy savings of light colored roofs: Results from three California demonstration sites  

SciTech Connect

Measured data and computer simulations have demonstrated the impact of roof albedo in reducing cooling energy use in buildings. Savings are a function of both climate and the amount of roof insulation. The cooling energy savings for reflective roofs are highest in hot climates. A reflective roof may also lead to higher heating energy use. Reflective coatings are also used in commercial buildings to protect the roofing membrane, and hence, maintain and prolong the useful life of the roof. Reflectivity of coatings changes with weathering and aging which in turn could have an effect on building cooling-energy savings. For that reason, reflective roof coatings are not primarily marketed for their energy savings potential. To monitor the field performance of reflective coatings, the authors initiated a demonstration project where three commercial buildings in California were painted with light-colored roof coatings. The buildings are two medical care centers and one drug store. At all sites, the roof reflectance, both fresh and aged, and cooling energy use were monitored. In addition, they measured temperature throughout the roof systems and inside the conditioned space. In the monitored buildings, increasing the roof reflectance from an initial value of about 20% to 60%, dropped the roof temperature on hot summer afternoons by about 45 F. Summertime standard-weekday average daily air-conditioning savings were 18% (198 kWh) in the first medical office building, 13% (86 kWh) in the second medical office building, and 2% (13 kWh) in the drug store. The overall u-value of the roofs had dictated the impact of roof reflectance.

Thermal Performance Evaluation of Innovative Metal Building Roof Assemblies  

Science Conference Proceedings (OSTI)

In order to meet the coming energy codes, multiple layers of various insulation types will be required. The demand for greater efficiency has pushed insulation levels beyond the cavity depth. These experiments show the potential for improving metal building roof thermal performance. Additional work is currently being done by several stakeholders, so the data is expanding. These experiments are for research and development purposes, and may not be viable for immediate use.

Equilibrium thermal characteristics of a building integrated photovoltaic tiled roof  

SciTech Connect

Photovoltaic (PV) modules attain high temperatures when exposed to a combination of high radiation levels and elevated ambient temperatures. The temperature rise can be particularly problematic for fully building integrated PV (BIPV) roof tile systems if back ventilation is restricted. PV laminates could suffer yield degradation and accelerated aging in these conditions. This paper presents a laboratory based experimental investigation undertaken to determine the potential for high temperature operation in such a BIPV installation. This is achieved by ascertaining the dependence of the PV roof tile temperature on incident radiation and ambient temperature. A theory based correction was developed to account for the unrealistic sky temperature of the solar simulator used in the experiments. The particular PV roof tiles used are warranted up to an operational temperature of 85 C, anything above this temperature will void the warranty because of potential damage to the integrity of the encapsulation. As a guide for installers, a map of southern Europe has been generated indicating locations where excessive module temperatures might be expected and thus where installation is inadvisable. (author)

Load test of the 272E Building high bay roof deck and support structure  

SciTech Connect

The 272E Building high bay roof area was load tested according to the approved load-test procedure. The 272E Building is located in the 200 East Area of the Hanford Site and has the following characteristics: Roof deck -- wood decking supported by 4 x 14 timber purlins; Roof membrane -- tar and gravel; Roof slope -- flat (<10 deg); and Roof elevation -- maximum height of about 63 ft. The 272 Building was visited in August 1992 for a visual inspection. During this inspection, cracked areas were visible in the decking, but it was not possible to determine whether these cracks extended completely through the decking, which is 2-in. thick. The building was revisited in March 1994 for the purpose of writing this test report. Because the roof requires personnel access, a test was determine to be the best way to qualify the roof. The pre-test briefing consisted of filling out the pre-test checklist, discussing proper lifting techniques, reviewing the fall-protection plan, reviewing the job hazards analysis, and reviewing the robot travel path. The load-test results consist of visual observations and the test engineer`s conclusions. Visual observations found no adverse conditions such as large deflections or permanent deformations. No deflection measurements were recorded because the tar and gravel on roof get displaced by the robot tracks; the result is large variations in deflection measurements. The conclusions are that the roof has been qualified for 500-lb total roof load and that the ``No Roof Access`` signs can be changed to ``Roof Access Restricted`` signs.

Monitoring the Energy-Use Effects of Cool Roofs on California Commercial Buildings  

DOE Green Energy (OSTI)

Solar-reflective roofs stay cooler in the sun than solar-absorptive roofs. Such ''cool'' roofs achieve lower surface temperatures that reduce heat conduction into the building and the building's cooling load. The California Energy Commission has funded research in which Lawrence Berkeley National Laboratory (LBNL) has measured the electricity use and peak demand in commercial buildings to document savings from implementing the Commission's Cool Roofs program. The study seeks to determine the savings achieved by cool roofs by monitoring the energy use of a carefully selected assortment of buildings participating in the Cool Roofs program. Measurements were needed because the peak savings resulting from the application of cool roofs on different types of buildings in the diverse California climate zones have not been well characterized to date. Only a few occupancy categories (e.g., office and retail buildings) have been monitored before this, and those were done under a limited number of climatic conditions. To help rectify this situation, LBNL was tasked to select the buildings to be monitored, measure roof performance before and after replacing a hot roof by a cool roof, and document both energy and peak demand savings resulting from installation of cool roofs. We monitored the effects of cool roofs on energy use and environmental parameters in six California buildings at three different sites: a retail store in Sacramento; an elementary school in San Marcos (near San Diego); and a 4-building cold storage facility in Reedley (near Fresno). The latter included a cold storage building, a conditioning and fruit-palletizing area, a conditioned packing area, and two unconditioned packing areas (counted as one building).

Building Green in Greensburg: Kiowa County Courthouse  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Courthouse Courthouse The Kiowa County Courthouse, originally built in 1914, was one of the only buildings not completely destroyed by the tornado. However, it was severely damaged by a vehicle that crashed through the roof, allowing rain to fall inside for 3 days. Luckily, most of the County's paperwork was salvaged thanks to quick action taken by the community the day after the tornado. Completed in July 2009, the building was renovated with sustainable and energy- saving technologies while staying true to the structure's original design. It is designed to meet the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED ® ) Gold designation and is projected to be 37% more energy efficient than an ASHRAE 90.1-2004 energy code minimum courthouse.

Liquid water in low sloped roofs almost always causes problems. Roofs are designed only to control the migration of vapor, if at all. Small amounts of water leakage/penetration, may cause mold growth or catastrophic corrosion in current roofs systems. In a recent paper by the authors the effect of exterior surface emissive and absorptive properties was found to have a significant effect on the moisture performance of a roof that had a leak. Depending on the surface characteristics, roof systems can be designed to effectively manage water penetration, but at an energy cost. In the roofs system examined previously, air leakage was not included. In the present study, the authors reinvestigated the effect of water penetration and the influence of air leakage on the hygrothermal performance of a few selected roofs. The drying potential of a groove ventilated roof is examined. The performance concept is based on the fact that warming up of air in the groove increases it's ability to transport moisture to the outside. Solar radiation raises the temperature of air in the grooves and on average, during a sunny summer day 0.5 L of water can be ventilated out of the roof per 1m width of the roof. In this paper, one climatic condition was investigated; a hot and humid Climate representative of Houston, TX. The specific questions that the paper addresses are: What are the vapor and liquid control dynamic involved in the moisture migration of a roof in Houston TX? and how does airflow influence the performance of a roof that is initially wet ? A state-of-the-art numerical model was used to address these issues. Results showed that the drying potential depends on the ventilation rates. The roof system with ventilation grooves dried out faster from the initially wet stage than the roof without the ventilation grooves. The total increase in heat loss of the roof was found to be between 0 - 5 % depending on the thickness of the insulation. The ventilation can cool down the temperature of the roof in the middle of a hot and sunny day thus reducing the heat load to the inside.

Cooling energy savings potential of light-colored roofs for residential and commercial buildings in 11 US metropolitan areas  

SciTech Connect

Light-colored roofs reflect more sunlight than dark roofs, thus they keep buildings cooler and reduce air-conditioning demand. Typical roofs in the United States are dark, which creates a potential for savings energy and money by changing to reflective roofs. In this report, the authors make quantitative estimates of the impact of roof color by simulating prototypical buildings with light- and dark-colored roofs and calculating savings by taking the differences in annual cooling and heating energy use, and peak electricity demand. Monetary savings are calculated using local utility rates. Savings are estimated for 11 U.S. Metropolitan Statistical Areas (MSAs) in a variety of climates.

Asphalt Roofing Shingles Into Energy Project Summary Report  

DOE Green Energy (OSTI)

Based on a widely cited September, 1999 report by the Vermont Agency of Natural Resources, nearly 11 million tons of asphalt roofing shingle wastes are produced in the United States each year. Recent data suggests that the total is made up of about 9.4 million tons from roofing tear-offs and about 1.6 million tons from manufacturing scrap. Developing beneficial uses for these materials would conserve natural resources, promote protection of the environment and strengthen the economy. This project explored the feasibility of using chipped asphalt shingle materials in cement manufacturing kilns and circulating fluidized bed (CFB) boilers. A method of enhancing the value of chipped shingle materials for use as fuel by removing certain fractions for use as substitute raw materials for the manufacture of new shingles was also explored. Procedures were developed to prevent asbestos containing materials from being processed at the chipping facilities, and the frequency of the occurrence of asbestos in residential roofing tear-off materials was evaluated. The economic feasibility of each potential use was evaluated based on experience gained during the project and on a review of the well established use of shingle materials in hot mix asphalt. This project demonstrated that chipped asphalt shingle materials can be suitable for use as fuel in circulating fluidized boilers and cement kilns. More experience would be necessary to determine the full benefits that could be derived and to discover long term effects, but no technical barriers to full scale commercial use of chipped asphalt shingle materials in these applications were discovered. While the technical feasibility of various options was demonstrated, only the use of asphalt shingle materials in hot mix asphalt applications is currently viable economically.

Attic or Roof? An Evaluation of Two Advanced Weatherization Packages  

SciTech Connect

This project examines implementation of advanced retrofit measures in the context of a large-scale weatherization program and the archetypal Chicago brick bungalow. One strategy applies best practice air sealing methods and a standard insulation method to the attic floor. The other strategy creates an unvented roof assembly using materials and methods typically available to weatherization contractors. Through implementations of the retrofit strategies in a total of eight (8) test homes, the research found that the two different strategies achieve similar reductions in air leakage measurement (55%) and predicted energy performance (18%) relative to the pre-retrofit conditions.

Roof Integrated Solar Absorbers: The Measured Performance of ''Invisible'' Solar Collectors: Preprint  

DOE Green Energy (OSTI)

The Florida Solar Energy Center (FSEC), with the support of the National Renewable Energy Laboratory, has investigated the thermal performance of solar absorbers that are an integral, yet indistinguishable, part of a building's roof. The first roof-integrated solar absorber (RISA) system was retrofitted into FSEC's Flexible Roof Facility in Cocoa, Florida, in September 1998. This ''proof-of-concept'' system uses the asphalt shingle roof surface and the plywood decking under the shingles as an unglazed solar absorber. Data was gathered for a one-year period on the system performance. In Phase 2, two more RISA prototypes were constructed and submitted for testing. The first used the asphalt shingles on the roof surface with the tubing mounted on the underside of the plywood decking. The second prototype used metal roofing panels over a plywood substrate and placed the polymer tubing between the plywood decking and the metal roofing. This paper takes a first look at the thermal performance results for the ''invisible'' solar absorbers that use the actual roof surface of a building for solar heat collection.

A guidebook for insulated low-slope roof systems. IEA Annex 19, Low-slope roof systems: International Energy Agency Energy Conservation in Buildings and Community Systems Programme  

SciTech Connect

Low-slope roof systems are common on commercial and industrial buildings and, to a lesser extent, on residential buildings. Although insulating materials have nearly always been a component of low-slope roofs, the amount of insulation used has increased in the past two decades because of escalation of heating and cooling costs and increased awareness of the need for energy conservation. As the amount of insulation has increased, the demand has intensified for design, installation, and maintenance information specifically for well-insulated roofs. Existing practices for design, installation, and maintenance of insulated roofs have evolved from experience. Typically, these practices feature compromises due to the different properties of materials making up a given roof system. Therefore, they should be examined from time to time to ensure that they are appropriate as new materials continue to enter the market and as the data base on existing systems expands. A primary purpose of this International Energy Agency (IEA) study is to assess current roofing insulation practices in the context of an accumulating data base on performance.

An office building used as a federal test bed for energy-efficient roofs  

SciTech Connect

The energy savings benefits of re-covering the roof of an existing federal office building with a sprayed polyurethane foam system are documented. The building is a 12,880 ft{sup 2} (1,197 m{sup 2}), 1 story, masonry structure located at the Oak Ridge National Laboratory (ORNL), Oak Ridge, TN. Prior to re-covering, the roof had a thin fiberglass insulation layer, which had become partially soaked because of water leakage through the failed built-up roof membrane. The average R-value for this roof measured at 2 hr{center_dot}ft{sup 2}{center_dot}{degrees}F/Btu (0.3 m{sup 2} {center_dot}K/W). After re-covering the roof, it measured at 13 hr{center_dot}ft{sup 2}{degrees}F/Btu (2.3 m{sup 2}{center_dot}K/W). The building itself is being used as a test bed to document the benefits of a number of energy efficiency improvements. As such, it was instrumented to measure the half-hourly energy consumption of the whole building and of the individual rooftop air conditioners, the roof heat fluxes and the interior air and roof temperatures. These data were used to evaluate the energy effectiveness of the roof re-covering action. The energy savings analysis was done using the DOE-2.lE building simulation program, which was calibrated to match the measured data. The roof re-covering led to around 10% cooling energy savings and around 50% heating energy savings. The resulting energy cost reductions alone are not sufficient to justify re-covered roofs for buildings having high internal loads, such as the building investigated here. However the energy savings do contribute significantly to the measure`s Savings-to-Investment Ratio (SIR).

Jackson Park Hospital Green Building Medical Center  

SciTech Connect

Jackson Park Hospital completed the construction of a new Medical Office Building on its campus this spring. The new building construction has adopted the City of Chicago's recent focus on protecting the environment, and conserving energy and resources, with the introduction of green building codes. Located in a poor, inner city neighborhood on the South side of Chicago, Jackson Park Hospital has chosen green building strategies to help make the area a better place to live and work. The new green building houses the hospital's Family Medicine Residency Program and Specialty Medical Offices. The residency program has been vital in attracting new, young physicians to this medically underserved area. The new outpatient center will also help to allure needed medical providers to the community. The facility also has areas designated to women's health and community education. The Community Education Conference Room will provide learning opportunities to area residents. Emphasis will be placed on conserving resources and protecting our environment, as well as providing information on healthcare access and preventive medicine. The new Medical Office Building was constructed with numerous energy saving features. The exterior cladding of the building is an innovative, locally-manufactured precast concrete panel system with integral insulation that achieves an R-value in excess of building code requirements. The roof is a 'green roof' covered by native plantings, lessening the impact solar heat gain on the building, and reducing air conditioning requirements. The windows are low-E, tinted, and insulated to reduce cooling requirements in summer and heating requirements in winter. The main entrance has an air lock to prevent unconditioned air from entering the building and impacting interior air temperatures. Since much of the traffic in and out of the office building comes from the adjacent Jackson Park Hospital, a pedestrian bridge connects the two buildings, further decreasing the amount of unconditioned air that enters the office building. The HVAC system has an Energy Efficiency Rating 29% greater than required. No CFC based refrigerants were used in the HVAC system, thus reducing the emission of compounds that contribute to ozone depletion and global warming. In addition, interior light fixtures employ the latest energy-efficient lamp and ballast technology. Interior lighting throughout the building is operated by sensors that will automatically turn off lights inside a room when the room is unoccupied. The electrical traction elevators use less energy than typical elevators, and they are made of 95% recycled material. Further, locally manufactured products were used throughout, minimizing the amount of energy required to construct this building. The primary objective was to construct a 30,000 square foot medical office building on the Jackson Park Hospital campus that would comply with newly adopted City of Chicago green building codes focusing on protecting the environment and conserving energy and resources. The energy saving systems demonstrate a state of the-art whole-building approach to energy efficient design and construction. The energy efficiency and green aspects of the building contribute to the community by emphasizing the environmental and economic benefits of conserving resources. The building highlights the integration of Chicago's new green building codes into a poor, inner city neighborhood project and it is designed to attract medical providers and physicians to a medically underserved area.

Quantum Fisher information places the fundamental limit to the accuracy of estimating an unknown parameter. Here we shall provide the quantum Fisher information an operational meaning: a mixed state can be so prepared that a given observable has the minimal averaged variance, which equals exactly to the quantum Fisher information for estimating an unknown parameter generated by the unitary dynamics with the given observable as Hamiltonian. In particular we shall prove that the quantum Fisher information is the convex roof of the variance, as conjectured by Toth and Petz based on numerical and analytical evidences, by constructing explicitly a pure-state ensemble of the given mixed state in which the averaged variance of a given observable equals to the quantum Fisher information.

A summary is presented of a pilot aerial infrared roof top study conducted by the Minnesota Energy Agency. Infrared surveys of 27 Minnesota cities were conducted during the fall and winter of the 1976-1977 heating season. In addition, conventional daytime color photographs were taken of several cities. Film processing was done by the Environmental Protection Agency. The University of Minnesota conducted ground tests to verify the aerial infrared imagery. Thermograph dissemination centers were established in each city and training seminars and materials were prepared and delivered to dissemination center staff. A survey of homeowners who viewed their thermograph at a dissemination center were used to determine the energy savings resulting from the program. An Aerial Infrared Program Users Manual was prepared by the Energy Agency and the Remote Sensing Institute of Brookings, South Dakota.

Research on the Effect of a Planting Roof on the Thermal Load of a Business Building  

E-Print Network (OSTI)

A pair of comparative testing rooms (one with an ordinary roof and the other with a planting roof) was established in our laboratory, and in- situ measurement (in summer) data have been collected and treated. The indoor thermal environment was analyzed and the thermal load within each room was calculated Comparative analysis of thermal loads of these two rooms was done. Reduction of thermal load by the planting roof is clearly shown from our research work. A theoretical analysis of the effect of the planting roof on the room's thermal load was done, and theoretical relations between outdoor air temperature and indoor thermal load within certain region were established. The feasibility analysis of the application of our research work to the business building was also completed. The summer cooling load reduction characteristics, the energy saving characteristics on air conditioning system, the yearly electricity consumption reduction, the yearly consumption amount reduction of Primary Energy, the discharge amount reduction of sensible heat to outdoor atmosphere in summer, and the yearly discharge amount reduction of greenhouse gases to the outdoor atmosphere from air conditioning system due to the planting roof are also predicted. A corresponding economic analysis is also presented in this paper. The results show the advantages of the planting roof, and also promote the widespread application of the planting roof to business buildings.

Application of Spray Foam Insulation Under Plywood and Oriented Strand Board Roof Sheathing  

SciTech Connect

Unvented roof strategies with open cell and closed cell spray polyurethane foam insulation sprayed to the underside of roof sheathing have been used since the mid-1990's to provide durable and efficient building enclosures. However, there have been isolated moisture related incidents reported anecdotally that raise potential concerns about the overall hygrothermal performance of these systems. The incidents related to rainwater leakage and condensation concerns. Condensation concerns have been extensively studied by others and are not further discussed in this report. This project involved hygrothermal modeling of a range of rainwater leakage and field evaluations of in-service residential roofs using spray foam insulation. All of the roof assemblies modeled exhibited drying capacity to handle minor rainwater leakage. All field evaluation locations of in-service residential roofs had moisture contents well within the safe range for wood-based sheathing. Explorations of eleven in-service roof systems were completed. The exploration involved taking a sample of spray foam from the underside of the roof sheathing, exposing the sheathing, then taking a moisture content reading. All locations had moisture contents well within the safe range for wood-based sheathing. One full-roof failure was reviewed, as an industry partner was involved with replacing structurally failed roof sheathing. In this case the manufacturer's investigation report concluded that the spray foam was installed on wet OSB based on the observation that the spray foam did not adhere well to the substrate and the pore structure of the closed cell spray foam at the ccSPF/OSB interface was indicative of a wet substrate.

Design, effectiveness, and construction of passive-thermal-control roofing shingles. Technical final report  

Science Conference Proceedings (OSTI)

The concept of a passive thermal control roofing shingle, which is a shingle that reflects the summer sun and absorbs the winter sun, is discussed. Such a shingle will reduce summer cooling and winter heating costs and conserve electricity and natural gas or heating oil. Design calculations indicate that it is possible to design shingles for particular latitudes and styles of roof which absorb nearly all of the winter solar energy and reflect nearly all of the summer solar energy. Calculations of the energy savings and cost effectiveness of the passive thermal control roofing shingle indicate that it is most cost effective on all south facing pitched roofs regardless of heating fuel type, and on flat or east or west facing roofs that are heated with costly fuels such as electricity or heating oil. The shingle is most effective on poorly insulated structures. If the cost of the shingle is about one dollar per square foot it will be cost effective in these applications. Additional calculations demonstrate the feasibility of using the passive thermal control roofing shingle in conjunction with a heat pump to pump heat absorbed by the shingle into a well insulated structure. Construction of a variety of models of the passive thermal control roofing shingle illustrate numerous alternate methods of manufacture. A profile extruded, plastic, glazed shingle appears to be the most promising approach. Additionally, extruded plastic reflector assemblies of various kinds could be added to existing shingled roofs. Use of a glazed shingle can increase the effectiveness of the passive thermal control roofing shingle by reducing convective heat losses.

The Effects of Infrared-Blocking Pigments and Deck Venting on Stone-Coated Metal Residential Roofs  

Science Conference Proceedings (OSTI)

Field data show that stone-coated metal shakes and S-mission tile, which exploit the use of infraredblocking color pigments (IrBCPs), along with underside venting reduce the heat flow penetrating the conditioned space of a residence by 70% compared with the amount of heat flow penetrating roofs with conventional asphalt shingles. Stone-coated metal roof products are typically placed on battens and counter-battens and nailed through the battens to the roof deck. The design provides venting on the underside of the metal roof that reduces the heat flow penetrating a home. The Metal Construction Association (MCA) and its affiliate members installed stone-coated metal roofs with shake and S-mission tile profiles and a painted metal shake roof on a fully instrumented attic test assembly at Oak Ridge National Laboratory (ORNL). Measurements of roof, deck, attic, and ceiling temperatures; heat flows; solar reflectance; thermal emittance; and ambient weather were recorded for each of the test roofs and also for an adjacent attic cavity covered with a conventional pigmented and direct nailed asphalt shingle roof. All attic assemblies had ridge and soffit venting; the ridge was open to the underside of the stone-coated metal roofs. A control assembly with a conventional asphalt shingle roof was used for comparing deck and ceiling heat transfer rates.

Necessary conditions include: A plan that is realistic and sustainable; Partnership that share the efforts and benefits of Green results; and A continuous improvement process, i.e. the flexibility to evolve with a dynamic industry and market. A successful Green plan combines vision, initiative, and a willingness to invest in the right tools. To implement a successful plan, leaders have recognized that, in light of the barriers that exist, real progress cannot be made alone. Because of common interest, core stakeholders are natural and necessary allies. As the public acceptance of Green increases, core stakeholders are challenging the status quo. Consequently, stakeholders are not risking inaction, and are connecting to achieve the rewards of being Green.

Condensation Risk of Mechanically Attached Roof Systems in Cold Climate Zones  

Science Conference Proceedings (OSTI)

A white roof, cool roof, is constructed to decrease thermal loads from solar radiation, therefore saving energy by decreasing the cooling demands. Unfortunately, cool roofs with mechanically attached membrane, have shown to have a higher risk of intermediate condensation in the materials below the membrane in certain climates (Ennis & Kehrer, 2011) and in comparisons with similar construction with a darker exterior surface (Bludau, Zirkelbach, & Kuenzel, 2009). As a consequence, questions have been raised regarding the sustainability and reliability of using cool roof membranes in Northern U.S. climate zones. A white roof surface reflects more of the incident solar radiation in comparisons with a dark surface, which makes a distinguished difference on the surface temperature of the roof. However, flat roofs with either a light or dark surface and if facing a clear sky, are constantly losing energy to the sky due to the exchange of infrared radiation. This phenomenon exists both during the night and the day. During the day, if the sun shines on the roof surface, the exchange of infrared radiation typically becomes insignificant. During nights and in cold climates, the temperature difference between the roof surface and the sky can deviate up to 20 C (Hagentoft, 2001) which could result in a very cold surface temperature compared to the ambient temperature. Further, a colder surface temperature of the roof increases the energy loss and the risk of condensation in the building materials below the membrane. In conclusion, both light and dark coated roof membranes are cooled by the infrared radiation exchange during the night, though a darker membrane is more heated by the solar radiation during the day, thus decreasing the risk of condensation. The phenomenon of night time cooling from the sky and the lack of solar gains during the day is not likely the exclusive problem concerning the risk of condensation in cool roofs with mechanically attached membranes. Roof systems with thermoplastic membranes are prone to be more effected by interior air intrusion into the roof construction; both due to the wind induced pressure differences and due to the flexibility and elasticity of the membrane (Molleti, Baskaran, Kalinger, & Beaulieu, 2011). Depending on the air permeability of the material underneath the membrane, wind forces increase the risk of fluttering (also referred as billowing) of the thermoplastic membrane. Expectably, the wind induced pressure differences creates a convective air flow into the construction i.e. Page 2 air intrusion. If the conditions are right, moisture from the exchanging air may condensate on surfaces with a temperature below dew-point. The definite path of convective airflows through the building envelope is usually very difficult to determine and therefore simplified models (K nzel, Zirkelbach, & Scfafaczek, 2011) help to estimate an additional moisture loads as a result of the air intrusion. The wind uplifting pressure in combination with wind gusts are important factors for a fluttering roof. Unfortunately, the effect from a fluctuating wind is difficult to estimate as this is a highly dynamic phenomenon and existing standards (ASTM, 2011a) only take into account a steady state approach i.e. there is no guidance or regulations on how to estimate the air intrusion rate. Obviously, a more detailed knowledge on the hygrothermal performance of mechanically attached cool roof system is requested; in consideration to varying surface colors, roof air tightness, climate zones and indoor moisture supply.

Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool  

NLE Websites -- All DOE Office Websites (Extended Search)

Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool as You Thought it Was Speaker(s): Ronnen Levinson Date: June 30, 2009 - 12:00pm Location: LBNL Bldg. 66 Auditorium Solar reflectance is often used to estimate the solar heat gain and rate the "coolness" of roofs and pavements. A solar reflectance property measured by two popular ASTM standard test methods (E903, C1549) can underestimate the peak solar heat gain of a spectrally selective "cool colored" surface by nearly 100 W m-2 because it assumes that sunlight contains an unrealistically high fraction of near-infrared (invisible) energy. Its use in building energy simulations can overestimate cool-roof annual energy savings by more than 20%. I define a new and simple solar

Laboratory measurements of the drying rates of low-slope roofing systems  

Science Conference Proceedings (OSTI)

The service life of a roofing system typically ends when excessive amounts of water have entered the system. Roofing professionals determine whether the existing failed roofing system can be repaired or salvaged by recovering. A key element in this decision is whether the accumulated water will be able to leave the roofing system in a time frame that will prevent irreparable structural damage. There are several combined heat and mass transfer models that can be used to predict drying times for low-slope roofing systems. Very little experimental data exists that can be used to validate the performance of these models. To satisfy these needs, a series of laboratory experiments has been performed. Five test panels, comprised of a plywood deck, four types of roofing insulation, and a single ply membrane were installed in a climate simulator. The test panels were outfitted with temperature sensors and heat flux transducers, and were mounted on load cells. Water was added to the test panels and they were subjected to external diurnal cycles representative of summer and winter conditions for a southern US continental climate. The load cells supplied continuous records of the weights of the test panels; these data were used to compute the drying rates of the test panels. When these experiments were completed, the test panels were ``recovered`` with different thicknesses of insulation and the environmental conditions were reapplied to the test panels. This paper reports on the design and performance of these experiments. The data compiled during these tests supply insight into the effects of meteorological conditions, insulation R-value, insulation water vapor permeance, and roof recover on the rate that water will be removed from low-slope roofing systems.

The Trade-off between Solar Reflectance and Above-Sheathing Ventilation for Metal Roofs on Residential and Commercial Buildings  

Science Conference Proceedings (OSTI)

An alternative to white and cool-color roofs that meets prescriptive requirements for steep-slope (residential and non-residential) and low-slope (non-residential) roofing has been documented. Roofs fitted with an inclined air space above the sheathing (herein termed above-sheathing ventilation, or ASV), performed as well as if not better than high-reflectance, high-emittance roofs fastened directly to the deck. Field measurements demonstrated the benefit of roofs designed with ASV. A computer tool was benchmarked against the field data. Testing and benchmarks were conducted at roofs inclined at 18.34 ; the roof span from soffit to ridge was 18.7 ft (5.7 m). The tool was then exercised to compute the solar reflectance needed by a roof equipped with ASV to exhibit the same annual cooling load as that for a direct-to-deck cool-color roof. A painted metal roof with an air space height of 0.75 in. (0.019 m) and spanning 18.7 ft (5.7 m) up the roof incline of 18.34 needed only a 0.10 solar reflectance to exhibit the same annual cooling load as a direct-to-deck cool-color metal roof (solar reflectance of 0.25). This held for all eight ASHRAE climate zones complying with ASHRAE 90.1 (2007a). A dark heat-absorbing roof fitted with 1.5 in. (0.038 m) air space spanning 18.7 ft (5.7 m) and inclined at 18.34 was shown to have a seasonal cooling load equivalent to that of a conventional direct-to-deck cool-color metal roof. Computations for retrofit application based on ASHRAE 90.1 (1980) showed that ASV air spaces of either 0.75 or 1.5 in. (0.019 and 0.038 m) would permit black roofs to have annual cooling loads equivalent to the direct-to-deck cool roof. Results are encouraging, and a parametric study of roof slope and ASV aspect ratio is needed for developing guidelines applicable to all steep- and low-slope roof applications.

Frog (Rana clamitans) Frog (Rana clamitans) Hear what this frog's call sounds like! Calls courtesy of Dr. Alan J. Wolf, Center for Biology Education/Biology New Media Center Green frogs are fairly common. They are found in smaller permanent bodies of water, like shallow springs or streams. Green frogs call from early to mid-summer, and sometimes later in the year. They are fairly large (3 inches) and a dull green color. Patterns on older adults can be very different from each other. As green frogs age, the pattern goes from a random blotches (called "mottling") to being nearly invisible. Green frogs retain two very noticeable "dorso-lateral folds" that run from the head almost to the end of the body. This characteristic can help you identify green frogs in this area.

Thermal Performance of Exposed Composed Roofs in Very Hot Dry Desert Region in Egypt (Toshky)  

E-Print Network (OSTI)

Thermal performance for any building in hot dry region depend on the external climatic factor, the ability of the construction materials used in gained heat through day time and loss this heat through night time through the nocturnal radiation. Roof is considered the major part of the building envelop which exposed to high thermal load due to the high solar intensity and high outdoor air temperature through summer season which reach to 6 months. In Egypt the thermal effect of roof is increased as one go towards from north to south. This study evaluate the thermal performance of different test rooms with different roofs construction; uninsulated concrete, insulated concrete, double, plant, and active concrete roofs, constructed under the effect of external climatic condition of very hot and dry region in Egypt (Toshky region). The external climatic conditions and the temperature distribution inside the roof construction and the indoor air temperature were measured. The results of this study recognized that the thermal transmittance (UValue) has a major role in chosen the constructed materials. Also the thermal insulation considered the suitable manner for damping the thermal stresses through day time and makes the interior environment of the building near the comfort zone during most months of the year. Natural night and forced ventilation are more important in improving the internal conditions. The construction roof systems show that the indoor air temperature thermal damping reach to 96%, 90%, 89%, and 76% for insulated concrete, double, planted and uninsulated concrete roofs. The results also investigate the importance of using the earth as a cooling source through the active concrete system. Evaporative cooling and movable shading which are an integrated part of the guidelines for building design in hot dry region must be using.

Effects of temperature and humidity variations on the stability of coal mine roof rocks. Final report  

SciTech Connect

A high degree of correlation between strain developed in samples of roof rock and humidity changes was obtained in the laboratory. The strain developed across bedding planes was greater than strain developed parallel to bedding. In tests conducted underground, strain values were much lower and the data more scattered for similar humidity variations. Roof rock specimens reacted to a 10 pct change in humidity throughout a 7 to 10 day period before stabilizing, which seems to rule out daily humidity cycles as a factor in roof deterioration and indicates seasonal variations as a major cause. Very low annual temperature variations were recorded in active sections of the mine. At a 6 F annual variation developed strain would be only 10.5 microinches per inch, far below the strain magnitude for humidity variations and probably too low to be a factor in problems of roof deterioration. Laboratory strain tests on drill core samples were shown to be indicators of moisture sensitivity of roof rock, but neither chemical nor physical properties of the samples correlated with the strain data.

Application of Spray Foam Insulation Under Plywood and OSB Roof Sheathing (Fact Sheet)  

SciTech Connect

Spray polyurethane foams (SPFs) have advantages over alternative insulation methods because they provide air sealing in complex assemblies, particularly roofs. Spray foam can provide the thermal, air, and vapor control layers in both new and retrofit construction. Unvented roof strategies with open cell and closed cell SPF insulation sprayed to the underside of roof sheathing have been used since the mid-1990s to provide durable and efficient building enclosures. However, there have been isolated incidents of failures (either sheathing rot or SPF delamination) that raise some general concerns about the hygrothermal performance and durability of these systems. The primary risks for roof systems are rainwater leaks, condensation from diffusion and air leakage, and built-in construction moisture. This project directly investigated rain and indirectly investigated built-in construction moisture and vapor drives. Research involved both hygrothermal modeling of a range of rain water leakage scenarios and field evaluations of in-service residential roofs. Other variables considered were climate zone, orientation, interior relative humidity, and the vapor permeance of the coating applied to the interior face of open cell SPF.

Such 'cool' roofs achieve lower surface temperatures that reduce heat conduction into the building and the building's cooling load. We monitored the effects of cool roofs on energy use and environmental parameters in six California buildings at three different sites: a retail store in Sacramento; an elementary school in San Marcos (near San Diego); and a four-building cold storage facility in Reedley (near Fresno). The latter included a cold storage building, a conditioning and fruit-palletizing area, a conditioned packing area, and two unconditioned packing areas. Results showed that installing a cool roof reduced the daily peak roof surface temperature of each building by 33-42 K. In the retail store building in Sacramento, for the monitored period of 8 August-30 September 2002, the estimated savings in average air conditioning energy use was about 72 Wh/m{sup 2}/day (52%). On hot days when the afternoon temperature exceeded 38 C, the measured savings in average peak demand for peak hours (noon-5 p.m.) was about 10 W/m{sup 2} of conditioned area. In the school building in San Marcos, for the monitored period of 8 July-20 August 2002, the estimated savings in average air conditioning energy use was about 42-48 Wh/m{sup 2}/day (17-18%). On hot days, when the afternoon temperature exceeded 32 C, the measured savings in average peak demand for hours 10 a.m.-4 p.m. was about 5 W/m{sup 2} of conditioned area. In the cold storage facility in Reedley, for the monitored period of 11 July-14 September 2002, and 11 July-18 August 2003, the estimated savings in average chiller energy use was about 57-81 Wh/m{sup 2}/day (3-4%). On hot days when the afternoon temperature exceeded 38 C, the measured savings in average peak-period demand (average cooling-power demand during peak demand hours, typically noon-6 p.m.) was about 5-6 W/m{sup 2} of conditioned area. Using the measured data and calibrated simulations, we estimated savings for similar buildings installing cool roofs in retrofit applications for all 16 California climate zones. For similar retail stores in climate zones 2 and 4-16, installing a cool roof can save about 6-15 kWh/m{sup 2}/year of conditioned area. In climate zones 2-16, estimates of average peak demand savings for hours noon-5 p.m. range from 2.9 to 5.8 W/m{sup 2}. For similar school buildings in climate zones 2-16, installing a cool roof can save from 3 to 6 kWh/m{sup 2}/year of conditioned roof area. For all 16 climate zones estimates of average peak demand savings for hours noon-5 p.m. range from 2.6 to 3.8 W/m{sup 2}. In similar cold storage buildings in all 16 climate zones, installing a cool roof can save about 4.5-7.4 kWh/m{sup 2}/year of conditioned roof area. In all 16 climate zones, estimates of average peak demand savings for hours noon-5 p.m. range from 3.9 to 6.6 W/m{sup 2}.

A Prototype Roof Deck Designed to Self-Regulate Deck Temperature and Reduce Heat Transfer  

SciTech Connect

A prototype roof and attic assembly exploits the use of radiation, convection and insulation controls to reduce the heat transfer penetrating its roof deck by almost 85% of the heat transfer crossing a conventional roof and attic assembly. The assembly exhibited attic air temperatures that did not exceed the peak day outdoor ambient temperature. The design includes a passive ventilation scheme that pulls air from the soffit and attic into an inclined air space above the deck. The design complies with fire protection codes because the air intake is internal and closed to the elements. Field data were benchmarked against an attic computer tool and simulations made for new and retrofit home constructions in hot, moderate and cold climates to access economics for the assembly.

SOLAR RADIATION ESTIMATION ON BUILDING ROOFS AND WEB-BASED SOLAR CADASTRE  

E-Print Network (OSTI)

The aim of this study is the estimation of solar irradiance on building roofs in complex Alpine landscapes. Very high resolution geometric models of the building roofs are generated by means of advanced automated image matching methods. Models are combined with raster and vector data sources to estimate the incoming solar radiation hitting the roofs. The methodology takes into account for atmospheric effects, site latitude and elevation, slope and aspect of the terrain as well as the effects of shadows cast by surrounding buildings, chimneys, dormers, vegetation and terrain topography. An open source software solution has been developed and applied to a study area located in a mountainous site and containing some 1250 residential, commercial and industrial buildings. The method has been validated by data collected with a pyranometer and results made available through a prototype WebGIS platform. 1.

WIPP supplementary roof support system Room 1, Panel 1: Geotechnical field data analysis report  

SciTech Connect

The design of the Room 1, Panel 1, supplementary roof support system was finalized in September 1991, and the system successfully installed in the test bin area between the bulkheads by December 1991. Simultaneously with the support system installation, existing monitoring system was upgraded to meet the needs of the installed roof support. This included extensometers, closure stations, rockbolt load cells as well as survey measurements of roof sag and floor lift. A Project Control Group (PCG) was established in order to monitor room and support system performance. Weekly meetings of the PCG were held to review all monitored data against criteria set in the initial design, and to modify these where necessary. Records of these meetings have been kept, with copies of all data summaries and action notes. These data records are maintained in the Engineering data files. After more than ten months of monitoring and reviewing experience, several modifications have been made both to the way data has been reported as well as to the load adjustment criteria. The support system has performed as expected in the design, with no signs of instability developing considering the rates of roof deformation, the rock bolt loads and the observed fracture behavior in the roof. This is particularly true of the horizon in which the rockbolt anchors are located, the most critical part of the design. The distribution of load build-up, throughout the 286 rockbolt load cells installed, in the Room 1 has been found satisfactory, and the load increases as evaluated by the PCG on a weekly basis have been within the acceptable range. The minimum life of the installed support system is estimated at 15 years based on the highest roof expansion rate experienced to date. This report provides analysis of geotechnical field data collected up to December 1992.

Impact of Reflective Roofing on Cooling Electrical Use and Peak Demand in a Florida Retail Mall  

E-Print Network (OSTI)

Architects in hot climates have long recognized that reflective roof colors can reduce building cooling load. Experimentation spanning nearly three decades has shown that white roofing surfaces can significantly reduce surface temperatures and cooling loads (Givoni and Hoffmann, 1968; Reagan and Acklam, 1979; Griggs and Shipp, 1988; Anderson, 1989; Anderson et al., 1991 and Bansal et al., 1992). More importantly, measured cooling energy savings of white surfaces have been significant in California's climate (Akbari et al., 1991, 1992, 1997). In Florida, field research by the Florida Solar Energy Center (FSEC) since 1993 has quantified the impact of reflective roof coatings on sub-metered air conditioning (AC) consumption in tests in a dozen occupied homes (Parker et al., 1993; 1994; 1995; 1997). The coatings were applied to the roofs of each home in mid-summer after a month-long period of monitoring during which meteorological conditions, building temperatures and AC energy use were recorded. Using weather periods with similar temperatures and solar insolation, air conditioning energy use was reduced by 10% - 43% in the homes. The average drop in space cooling energy use was about 7.4 kWh/day or 19% of the pre-application air conditioning consumption. Unfortunately, until this project there has been little objective testing of the impact of roof whitening on the AC load of commercial buildings in Florida. Two demonstration sites have been monitored. The first was an elementary school in Cocoa Beach, Florida, which was monitored for a year before and after a white roof coating was applied. A final report on this project was published in the CADDET Newsletter (Parker et al., 1996a, b). The project demonstrated a 10% annual savings in chiller energy with a 30% reduction in peak cooling electrical demand. This paper summarizes the findings from the second demonstration at a commercial strip mall.

Why is grass green?  

NLE Websites -- All DOE Office Websites (Extended Search)

is grass green? is grass green? Name: Bob Whitbeck Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A Question: What causes grass to be green? Replies: Bob, Grass and most other plants are green because they contain a pigment known as chlorophyll. The chlorophyll is used in the process of photosynthesis where a plant produces sugar in the presence of sunlight. In fact the word 'photosynthesis' means literally to synthesize or 'make' from light (photo). There are, of course some plants which do not contain chlorophyll, and these generally get their nutrition (food) by other means. Some examples are the fungi which decompose dead, and sometimes living, tissue, for their food. You will find that a green plant needs light to make food. If the source of light is cut off, the plant dies. Mushrooms, which are fungi, do not require light to make food (they decompose matter as I mentioned above) and you can find mushrooms growing in almost total darkness.

TASK 2.5.7 FIELD EXPERIMENTS TO EVALUATE COOL-COLORED ROOFING  

Science Conference Proceedings (OSTI)

Aesthetically pleasing dark roofs can be formulated to reflect like a highly reflective white roof in the near infrared portion of the solar spectrum. New paint pigments increase the near infrared reflectance of exterior finishes by minimizing the absorption of near-infrared radiation (NIR). The boost in the NIR reflectance drops the surface temperatures of roofs and walls, which in turn reduces cooling-energy use and provides savings for the homeowner and relief for the utilities. In moderate and hot climates, a roof surface with high solar reflectance and high thermal emittance was shown by Akbari et al. (2004) and by Parker and Sherwin (1998) to reduce the exterior temperature and produce savings in comfort cooling. The new cool color pigments can potentially reduce emissions of carbon dioxide, which in turn reduces metropolitan heat buildup and urban smog. The pigments can also help conserve water resources otherwise used to clean and process fuel consumed by fossil-fuel driven power plants. Cool roofs also result in a lower ambient temperature that further decreases the need for air conditioning, retards smog formation, and improves thermal comfort. Parker, Sonne and Sherwin (2002) demonstrated that white barrel and white flat tiles reduced cooling energy consumption by 22% of the base load used by an adjacent and identical home having direct nailed dark shingles. Part of the savings was due to the reflectance of the white tiles; however, another part was due to the mass of the tile and to the venting occurring within the double batten installation. With, Cherry and Haig (2009) have studied the influence of the thermal mass and batten space ventilation and have found that, referenced to an asphalt shingle system, it can be equivalent to an additional 28 points of solar reflectivity. The double batten arrangement has wooden counter battens laid vertically (soffit-to-ridge) against the roof deck, and then the conventional battens are laid horizontally across the counter battens, providing a nailing surface for the concrete tile. This double batten construction forms an inclined air channel running from the soffit to the ridge. The bottom surface of the channel is formed by the roof decking and is relatively flat and smooth. The top surface is created by the underside of the roofing tiles, and is designed to be an air permeable covering to alleviate the underside air pressure and minimize wind uplift on the tiles. The resulting air flows also have a cooling influence which further complicates prediction of the heat penetrating through the deck because an accurate measure of the airflow is required to predict the heat transfer. Measured temperatures and heat flows at the roof surface, within the attic and at the ceiling of the houses are discussed as well as the power usage to help gauge the benefit of cool-pigmented reflective roof products fitted with and without ventilation above the roof deck. Ventilation occurring above the deck is an inherent feature for tile roof assemblies, and is formed by an air space between the exterior face of the roof sheathing and the underside of the tile. The greater the tile s profile the greater is the effect of the ventilation which herein is termed above-sheathing ventilation (ASV). However, because of the complexity of the thermally induced flow, little credit is allowed by state and federal building codes. ASHRAE (2005) provides empirical data for the effective thermal resistance of plane air spaces. A -in. (0.0191-m) plane air space inclined at 45 with the horizontal has an RUS-0.85 (RSI-0.15) . Our intent is to help further deploy cool color pigments in roofs by conducting field experiments to evaluate the new cool-colored roofing materials in the hot climate of Southern California. The collected data will be used to showcase and market the performance of new cool-roof products and also to help formulate and validate computer codes capable of calculating the heat transfer occurring within the attic and the whole building. Field measures and computer predictions showed that the d

In this work we investigate the regional climate and radiative effects of modifying surface albedo to mimic massive deployment of cool surfaces (roofs and pavements) and, separately, photovoltaic arrays across the United States. We use a fully coupled regional climate model, the Weather Research and Forecasting (WRF) model, to investigate feedbacks between surface albedo changes, surface temperature, precipitation and average cloud cover. With the adoption of cool roofs and pavements, domain-wide annual average outgoing radiation increased by 0.16 ± 0.03 W m-2 (mean ± 95% C.I.) and afternoon summertime temperature in urban locations was reduced by 0.11-0.53 "C, although some urban areas showed no statistically significant temperature changes. In response to increased urban albedo, some rural locations showed summer afternoon temperature increases of up to +0.27 "C and these regions were correlated with less cloud cover and lower precipitation. The emissions offset obtained by this increase in outgoing radiation is calculated to be 3.3 ± 0.5 Gt CO2 (mean ± 95% C.I.). The hypothetical solar arrays were designed to be able to produce one terawatt of peak energy and were located in the Mojave Desert of California. To simulate the arrays, the desert surface albedo was darkened, causing local afternoon temperature increases of up to +0.4 "C. Due to the solar arrays, local and regional wind patterns within a 300 km radius were affected. Statistically significant but lower magnitude changes to temperature and radiation could be seen across the domain due to the introduction of the solar arrays. The addition of photovoltaic arrays caused no significant change to summertime outgoing radiation when averaged over the full domain, as interannual variation across the continent obscured more consistent local forcing.

NLE Websites -- All DOE Office Websites (Extended Search)

Fourth National Green Power Marketing Conference Fourth National Green Power Marketing Conference Key Ingredients for Successful Markets Held May 10-11, 1999 in Philadelphia, Pennsylvania The Fourth National Green Power Marketing Conference was organized to examine the current state of green-power marketing and to explore opportunities to improve on the success of green-power sales in both regulated and deregulated markets. The conference was co-sponsored by the U.S. Department of Energy, Electric Power Research Institute, Renewable Energy Alliance, and Edison Electric Institute. View all of the Conference Presentations in Microsoft PowerPoint 95 (PPT) or Adobe Acrobat PDF format. Format is noted with file sizes. REPORT SUMMARY Today, in regulated monopoly markets, more than 50 utilities offer "green pricing" to their customers, but competitive green power marketing is still in early evolution. After a year of competitive market activity, it has become clear that the rules and mechanisms established for electric industry restructuring are critical to the success of green power marketing. The Fourth National Green Power Conference examined the current state of green power marketing, identified key market and policy needs under electric industry restructuring, and explored opportunities to improve on the success of green power sales in both regulated and deregulated markets.

Green's conjecture for general covers  

E-Print Network (OSTI)

We establish Green's syzygy conjecture for classes of covers of curves of higher Clifford dimension. These curves have an infinite number of minimal pencils, in particular they do not verify a well-known Brill-Noether theoretic sufficient condition that implies Green's conjecture. Secondly, we study syzygies of curves with a fixed point free involution and prove that sections of Nikulin surfaces of minimal Picard number 9, verify the classical Green Conjecture but fail the Prym-Green Conjecture on syzygies of Prym-canonical curves. This provides an explicit locus in the moduli space R_g where Green's Conjecture is known to hold.

Global Cooling: Policies to Cool the World and Offset Global Warming from CO2 Using Reflective Roofs and Pavements  

Science Conference Proceedings (OSTI)

Increasing the solar reflectance of the urban surface reduce its solar heat gain, lowers its temperatures, and decreases its outflow of thermal infrared radiation into the atmosphere. This process of 'negative radiative forcing' can help counter the effects of global warming. In addition, cool roofs reduce cooling-energy use in air conditioned buildings and increase comfort in unconditioned buildings; and cool roofs and cool pavements mitigate summer urban heat islands, improving outdoor air quality and comfort. Installing cool roofs and cool pavements in cities worldwide is a compelling win-win-win activity that can be undertaken immediately, outside of international negotiations to cap CO{sub 2} emissions. We propose an international campaign to use solar reflective materials when roofs and pavements are built or resurfaced in temperate and tropical regions.

The greening of synfuels  

SciTech Connect

Synfuels emit less carbon dioxide than oil and even reduce the amount of carbon in the atmosphere. For making synfuels green is by using large amounts of plant biomass along with coal and storing in the ground the CO{sub 2} emitted during the production of synfuels. The process of making synfuel is by turning coal into gas, which creates carbon monoxide and hydrogen. The resulting syngas is converted into diesel fuel, jet fuel, or chemical feedstock.

Predicting Current Serviceability And Residual Service Life Of Plywood Roof Sheathing Using  

E-Print Network (OSTI)

This report presents the findings and implications of a 10-year research program, carried out at the USDA Forest Service, Forest Products Laboratory, to develop kinetics-based service-life models for untreated and fire-retardant- (FR) treated plywood roof sheathing exposed to elevated in-service temperatures. This program was initiated because some FR-treated sheathing products were experiencing significant thermal degrade and needed to be replaced. This 10-year research program systematically identified the cause of the degradation and has resulted in new acceptance and performance standards and revisions to U.S. building codes. The strength loss was cumulatively related to FR chemistry, thermal exposure during pretreatment, treatment, and post-treatment processing, and in-service exposure. Quantitatively, a kinetics-based approach could be used to predict strength loss of plywood based on its time-- temperature exposure history. The research program then developed models to assess current condition, predict future hazard based on past service life, and predict residual serviceability of untreated and FR-treated plywood used as structural roof sheathing. Findings for each of these subjects are briefly described in this report. Results of research programs like this one can be used to extend the service life of wood by providing engineers with an estimate of residual serviceability and thereby avoiding premature removal. Many of the approaches in these kinetics-based servicelife models for plywood roof sheathing are directly applicable to the development of predictive durability models for wood and wood composite roof and wall sheathing that has been exposed to moisture and has eventually decayed. When those models are developed, they will help building code officials, ...

What is ``green``?  

SciTech Connect

This article presents a framework for identifying who and what is behind the concept of ``green,`` the dynamics in which this concept is applied, and the strategic importance of this topic for companies. There is a need--and a challenge--for companies to become ``greener.`` By integrating the knowledge of what is ``green`` into their business strategies, companies can become more sustainable, respond to society;s environmental demands in an ethical and equitable manner, avert risk, improve their efficiency; increase customer focus, and become more competitive. However, determining what is good for the environment is a complex task. And it is even more difficult to figure out how to link this knowledge to business practice. The full scientific information to know a company;s actual environmental impact, or what constitutes a positive or benign interaction with the natural environment does not yet exist. To have a complete understanding of what is best for the environment will take time, effort, and continuous multi-way dialogue. In the short-term, more can be learned about what is ``green`` from a range of social stakeholders who evaluate and make judgments about corporate environmental performance. Although the main task remains to identify whose opinion counts. The ultimate key for understanding this issue is when companies begin to make better environmental and business decisions that recognize the dynamics in which the similarities, differences, and inconsistencies in stakeholders` approaches take place, and the limitations in existing information, methodologies, and tools.

Roof and Attic Design Guidelines for new and retrofit Construction of Homes in Hot and Coild Climates  

SciTech Connect

Some guidelines for improving the energy efficiency of roofs and attics are presented and are based on the research of the DOE Building Technology. The results of combined analytical and experimental studies were used to benchmark computer tools, which in turn, were used to simulate homes in hot and cold climates. Adding floor and roof insulation, above deck ventilation, radiant barriers, cool color shingle, metal or tile roofs, sealing the attic floor, sealing the duct system and sealing the attic were simulated to compute the cost of energy savings. Results are prioritized to help building owners make an informed economic decision when contemplating roof and attic retrofits. Sealing the attic floor is a top retrofit option. The sealed attic approach and a new prototype roof assembly an insulated and ventilated roof are good options for retrofit work but have paybacks ranging from 15 to 25 years. A new sealed attic concept was simulated and computations show its simple payback is about 10 to 12 years in hot and cold climates; its first cost is significantly reduced from that of a spray foam approach. For new construction the best option is to keep the ducts out of the attic, make sure the attic floor is sealed and add at least code level of insulation to the ceiling.

INL Green Building Strategy  

Science Conference Proceedings (OSTI)

Green buildings, also known as sustainable buildings, resource efficient buildings, and high performance buildings, are structures that minimize the impact on the environment by using less energy and water, reducing solid waste and pollutants, and limiting the depletion of natural resources. As Idaho National Laboratory (INL) becomes the nations premier nuclear energy research laboratory, the physical infrastructure will be established to help accomplish the mission. This infrastructure, particularly the buildings, should incorporate green design features in order to be environmentally responsible and reflect an image of progressiveness and innovation to the public and prospective employees. With this in mind, the recommendations described in this strategy are intended to form the INL foundation for green building standards. The recommendations in this strategy are broken down into three levels: Baseline Minimum, Leadership in Energy and Environmental Design (LEED)Certification, and Innovative. Baseline Minimum features should be included in all new occupied buildings no matter what the purpose or size. These features do not require significant research, design, or capital costs and yet they can reduce Operation and Maintenance (O&M) costs and produce more environmentally friendly buildings. LEED Certification features are more aggressive than the Baseline Minimums in that they require documentation, studies, and/or additional funding. Combined with the Baseline Minimums, many of the features in this level will need to be implemented to achieve the goal of LEED certification. LEED Silver certification should be the minimum goal for all new buildings (including office buildings, laboratories, cafeterias, and visitor centers) greater than 25,000 square feet or a total cost of $10 million. Innovative features can also contribute to LEED certification, but are less mainstream than those listed in the previous two levels. These features are identified as areas where INL can demonstrate leadership but they could require significant upfront cost, additional studies, and/or development. Appendix A includes a checklist summary of the INL Green Building Strategy that can be used as a tool during the design process when considering which green building features to include. It provides a quick reference for determining which strategies have lower or no increased capital cost, yield lower O&M costs, increase employee productivity, and contribute to LEED certification.

PERFORMANCE EVALUATION OF A SUSTAINABLE AND ENERGY EFFICIENT RE-ROOFING TECHNOLOGY USING FIELD-TEST DATA  

Science Conference Proceedings (OSTI)

Three test attics were constructed to evaluate a new sustainable method of re-roofing utilizing photo-voltaic (PV) laminates, metal roofing panels, and PCM heat sink in the Envelope Systems Research Apparatus (ESRA) facility in the ORNL campus. Figure 1 is a picture of the three attic roofs located adjacent to each other. The leftmost roof is the conventional shingle roof, followed by the metal panel roof incorporating the cool-roof coating, and third from left is the roof with the PCM. On the PCM roof, the PV panels are seen as well; they're labelled from left-to-right as panels 5, 6 and 7. The metal panel roof consists of three metal panels with the cool-roof coating; in further discussion this is referred to as the infrared reflective (IRR) metal roof. The IRR metal panels reflect the incoming solar radiation and then quickly re-emit the remaining absorbed portion, thereby reducing the solar heat gain of the attic. Surface reflectance of the panels were measured using a Solar Spectrum Reflectometer. In the 0.35-2.0 {mu}m wavelength interval, which accounts for more than 94% of the solar energy, the IRR panels have an average reflectance of 0.303. In the infrared portion of the spectrum, the IRR panel reflectance is 0.633. The PCM roof consists of a layer of macro-encapsulated bio-based PCM at the bottom, followed by a 2-cm thick layer of dense fiberglass insulation with a reflective surface on top, and metal panels with pre-installed PV laminates on top. The PCM has a melting point of 29 C (84.2 F) and total enthalpy between 180 and 190 J/g. The PCM was macro-packaged in between two layers of heavy-duty plastic foil forming arrays of PCM cells. Two air cavities, between PCM cells and above the fiberglass insulation, helped the over-the-deck natural air ventilation. It is anticipated that during summer, this extra ventilation will help in reducing the attic-generated cooling loads. The extra ventilation, in conjunction with the PCM heat sink, are used to minimize thermal stresses due to the PV laminates on sunny days. In PV laminates sunlight is converted into electricity and heat simultaneous. In case of building integrated applications, a relatively high solar absorption of amorphous silicon laminates can be utilized during the winter for solar heating purposes with PCM providing necessary heat storage capacity. However, PV laminates may also generate increased building cooling loads during the summer months. Therefore, in this project, the PCM heat sink was to minimize summer heat gains as well. The PCM-fibreglass-PV assembly and the IRR metal panels are capable of being installed directly on top of existing shingle roofs during re-roofing, precluding the need for recycling or disposal of waste materials. The PV laminates installed on the PCM attic are PVL-144 models from Uni-Solar. Each laminate contains 22 triple junction amorphous silicon solar cells connected in series. The silicon cells are of dimensions 356 mm x 239 mm (14-in. x 9.4-in.). The PVL-144 laminate is encapsulated in durable ETFE (poly-ethylene-co-tetrafluoroethylene) high light-transmissive polymer. Table 1 lists the power, voltage and current ratings of the PVL-144 panel.

"My heating bills were quite high for a house this size, so I was a little alarmed," she says about her circa 1951 home, which doesn't even take up 1,000 square feet. This year, though, the Southeastern Idaho Community Action Agency had more funding than usual for its weatherization program because of $1.7 million in stimulus funding it will spend through March 2011. The agency ran a

Cooling energy savings potential of light-colored roofs for residential and commercial buildings in 11 US metropolitan areas  

SciTech Connect

The U.S. Environmental Protection Agency (EPA) sponsored this project to estimate potential energy and monetary savings resulting from the implementation of light-colored roofs on residential and commercial buildings in major U.S. metropolitan areas. Light-colored roofs reflect more sunlight than dark roofs, so they keep buildings cooler and reduce air-conditioning demand. Typically, rooftops in the United States are dark, and thus there is a potential for saving energy and money by changing to reflective roofs. Naturally, the expected savings are higher in southern, sunny, and cloudless climates. In this study, we make quantitative estimates of reduction in peak power demand and annual cooling electricity use that would result from increasing the reflectivity of the roofs. Since light-colored roofs also reflect heat in the winter, the estimates of annual electricity savings are a net value corrected for the increased wintertime energy use. Savings estimates only include direct reduction in building energy use and do not account for the indirect benefit that would also occur from the reduction in ambient temperature, i.e. a reduction in the heat island effect. This analysis is based on simulations of building energy use, using the DOE-2 building energy simulation program. Our methodology starts with specifying 11 prototypical buildings: single-family residential (old and new), office (old and new), retail store (old and new), school (primary and secondary), health (hospital and nursing home), and grocery store. Most prototypes are simulated with two heating systems: gas furnace and heat pumps. We then perform DOE-2 simulations of the prototypical buildings, with light and dark roofs, in a variety of climates and obtain estimates of the energy use for air conditioning and heating.

Green-Energy Transportation  

E-Print Network (OSTI)

Battery technology is the key bottleneck in many cyberphysical systems (CPS). For green-energy CPS transportation applications, such as hybrid electrical vehicles (HEVs) and plug-in HEVs (PHEVs), the battery system design is mostly based on lithium-ion rechargeable electrochemical battery technology, which is bulky, expensive, unreliable, and is the primary roadblock for PHEV adoption and market penetration. For PHEVs, the battery system performance and lifetime reliability are further affected by various user-dependent effects. Battery system modeling and user study are thus essential for battery system design and optimization. This paper presents detailed investigation on battery system modeling and user study for emerging PHEVs. The proposed modeling solution can accurately characterize battery system run-time charge-cycle efficiency, and long-term cycle life. In particular, it models battery system capacity variation and fading due to fabrication and run-time aging effects. An embedded monitoring system is designed and deployed in a number of HEVs and PHEVs, which can monitor users driving behavior and battery usage at real time. Using the proposed modeling and monitoring solutions, we conduct user study to investigate battery system run-time usage, characterize user driving behavior, and study the impact of user driving patterns on battery system run-time charge-cycle efficiency, capacity variation and reliability, and life-cycle economy. This work is the first step in battery system design and optimization for emerging green-energy CPS transportation applications. 1.

Mandatory Utility Green Power Option Mandatory Utility Green Power Option A number of states have adopted policies requiring or encouraging electricity suppliers to offer green power options to consumers. This section provides summaries of these policies and links to the full text of the legislation or public utility commission rules. Connecticut Iowa Maine Minnesota Montana New Jersey New Mexico Oregon Vermont Virginia Washington Connecticut June 2003—On June 26, Connecticut Governor John G. Rowland signed a bill (SB 733) amending the state's Electric Restructuring Act and granting authority to the Department of Public Utility Control (DPUC) to require electric distribution companies to offer green power options. The legislation enables the DPUC to determine the terms and conditions of renewable energy or energy efficiency options, including the contract terms and the minimum percentage of electricity to be derived from renewable energy sources. The green energy options will be developed and implemented by third-party companies selected through a competitive bidding process.

First DOE/EPRI Green Pricing Workshop First DOE/EPRI Green Pricing Workshop April 11-12, 1996 Golden, Colorado Prepared by Blair G. Swezey, National Renewable Energy Laboratory Terry M. Peterson, Electric Power Research Institute I. Overview Green pricing is an evolving utility service that responds to utility customers' preferences for electricity derived from renewable energy sources such as solar, wind, or biomass. Under green pricing, utilities offer customers a voluntary program or service to support electricity generated from renewable energy systems. Customers are asked to pay a rate premium, which is meant to cover the costs that the utility incurs above those paid today for electricity from conventional fuels. Utilities are considering green pricing as a way to build customer loyalty, deploy popular renewable technologies, expand business lines and expertise, and improve understanding of customer response to unbundled pricing and services.

Three-dimensional analysis of AP600 standard plant shield building roof  

SciTech Connect

The AP600 passive containment vessel is surrounded by a concrete cylindrical shell covered with a truncated conical roof. This roof supports the passive containment cooling system (PCS) annular tank, shield plate and other nonstructural attachments. When the shield building is subjected to different loading combinations as defined in the Standard Review Plan (SRP), some of the sections in the shield building could experience forces in excess of their design values. This report summarized the three-dimensional finite element analysis that was conducted to review the adequacy of the proposed Westinghouse shield building design. The ANSYS finite element software was utilized to analyze the Shield Building Roof (SBR) under dead, snow, wind, thermal and seismic loadings. A three-dimensional model that included a portion of the shield building cylindrical shell, the conical roof and its attachments, the eccentricities at the cone-cylinder connection and at the compression ring and the PCS tank was developed. Mesh sensitivity studies were conducted to select appropriate element size in the cylinder, cone, near air intakes and in the vicinity of the eccentricities. Also, a study was carried out to correctly idealize the water-structure interaction in the PCS tank. Response spectrum analysis was used to calculate the internal forces at different sections in the SBR under Safe Shutdown Earthquake (SSE). Forty-nine structural modes and twenty sloshing modes were used. Two horizontal components of the SSE together with a vertical component were used. Modal stress resultants were combined taking into account the effects of closely spaced modes. The three earthquake directions were combined by the Square Root of the Sum Squares method. Two load combinations were studied. The load combination that included dead, snow, fluid, thermal and seismic loads was selected to be the most critical. Interaction diagrams for critical sections were developed and used to check the design adequacy. The results demonstrated that provided area of steal on each face of several sections of the AP600 SBR was inadequate. This was also noticed when comparing the total provided area of steel per section, i.e., the area of steel on both faces. The discrepancy between Westinghouse results and these reported herein could have resulted from the different finite element mesh sizes and the assumption used in Westinghouse design.

Measuring Energy Measuring Energy Sustainability David L. Greene Abstract For the purpose of measurement, energy sustainability is defi ned as ensuring that future generations have energy resources that enable them to achieve a level of well-being at least as good as that of the current generation. It is recognized that there are valid, more comprehensive understandings of sustainability and that energy sustainability as de- fi ned here is only meaningful when placed in a broader context. Still, measuring energy sustainability is important to society because the rates of consumption of some fossil resources are now substantial in relation to measures of ultimate resources, and because confl icts between fossil energy use and environmental sustainability are intensifying.

Project Overcoat - An Exploration of Exterior Insulation Strategies for 1-1/2-Story Roof Applications in Cold Climates  

SciTech Connect

The development of an alternative method to interior-applied insulation strategies or exterior applied 'band-aids' such as heat tapes and ice belts may help reduce energy needs of millions of 1-1/2 story homes while reducing the risk of ice dam formation. A potential strategy for energy improvement of the roof is borrowed from new construction best practices: Here an 'overcoat' of a continuous air, moisture, and thermal barrier is applied on the outside of the roof structure for improved overall performance. The continuous insulation of this approach facilitates a reduction in thermal bridging which could further reduce energy consumption and bring existing homes closer to meeting the Building America goals for energy reduction. Research favors an exterior approach to deep energy retrofits and ice dam prevention in existing homes. The greatest amount of research focuses on whole house deep energy retrofits leaving a void in roof-only applications. The research is also void of data supporting the hygrothermal performance, durability, constructability, and cost of roof-only exterior overcoat strategies. Yet, contractors interviewed for this report indicate an understanding that exterior approaches are most promising for mitigating ice dams and energy loss and are able to sell these strategies to homeowners.

Roof-top solar energy potential under performance-based building energy codes: The case of Spain  

Science Conference Proceedings (OSTI)

The quantification at regional level of the amount of energy (for thermal uses and for electricity) that can be generated by using solar systems in buildings is hindered by the availability of data for roof area estimation. In this note, we build on an existing geo-referenced method for determining available roof area for solar facilities in Spain to produce a quantitative picture of the likely limits of roof-top solar energy. The installation of solar hot water systems (SHWS) and photovoltaic systems (PV) is considered. After satisfying up to 70% (if possible) of the service hot water demand in every municipality, PV systems are installed in the remaining roof area. Results show that, applying this performance-based criterion, SHWS would contribute up to 1662 ktoe/y of primary energy (or 68.5% of the total thermal-energy demand for service hot water), while PV systems would provide 10 T W h/y of electricity (or 4.0% of the total electricity demand).

Measured energy savings and demand reduction from a reflective roof membrane on a large retail store in Austin  

SciTech Connect

In this study, we measured and documented summertime air-conditioning (a/c) daily energy savings and demand reduction from a reflective roof membrane retrofit on a large retail store in Austin, Texas. The original black rubber membrane was replaced with white thermoplastic resulting in a decrease in the average maximum roof surface temperature from 168 degrees F (76 degrees C) to 126 degrees F (52 degrees C). This building, with 100,000ft2 (9300m2) of roof area, yielded 3.6Wh/ft2 (39Wh/m2) in a/c average daily energy savings and 0.35W/ft2 (3.8W/m2) in average reduced demand. Total a/c annual abated energy and demand expenditures were estimated to be $7200 or $0.072/ft2 ($0.77/m2). Based on cost data provided by the building manager, the payback is instantaneous with negligible incremental combined labor and material costs. The estimated present value of future abated expenditures ranged from $62,000 to $71,000 over the baseline 13-year service life of the roof membrane.

Numerical evaluation of convex-roof entanglement measures with applications to spin rings  

SciTech Connect

We present two ready-to-use numerical algorithms to evaluate convex-roof extensions of arbitrary pure-state entanglement monotones. Their implementation leaves the user merely with the task of calculating derivatives of the respective pure-state measure. We provide numerical tests of the algorithms and demonstrate their good convergence properties. We further employ them in order to investigate the entanglement in particular few-spins systems at finite temperature. Namely, we consider ferromagnetic Heisenberg exchange-coupled spin-(1/2) rings subject to an inhomogeneous in-plane field geometry obeying full rotational symmetry around the axis perpendicular to the ring through its center. We demonstrate that highly entangled states can be obtained in these systems at sufficiently low temperatures and by tuning the strength of a magnetic field configuration to an optimal value which is identified numerically.

Effects of Soiling and Cleaning on the Reflectance and Solar HeatGain of a Light-Colored Roofing Membrane  

Science Conference Proceedings (OSTI)

A roof with high solar reflectance and high thermalemittance (e.g., a white roof) stays coolin the sun, reducing coolingpower demand in a conditioned building and increasing comfort in anunconditioned building. The high initial solar reflectance of a whitemembrane roof (circa 0.8) can be degraded by deposition of soot, dust,and/or algae to about 0.6 (range 0.3 to 0.8, depending on exposure) Weinvestigate the effects of soiling and cleaning on the solar spectralreflectance and solar absorptance of 15 initially white or light-graymembrane samples taken from roofs across the United States. Soot andorganic carbon were the two identifiable strongly absorbing contaminantson the membranes. Wiping was effective at removing soot, and less so atremoving organic carbon. Rinsing and/or washing removed nearly all of theremaining soil layer, with the exceptions of (a) thin layers of organiccarbon and (b) isolated dark spots of algae. Bleach was required toremove the last two features. The ratio of solar reflectance to unsoiledsolar reflectance (a measure of cleanliness) ranged from 0.41 to 0.89 forthe soiled samples; 0.53to 0.95 for the wiped samples; 0.74 to 0.98 forthe rinsed samples; 0.79 to 1.00 for the washed samples; and 0.94 to 1.02for the bleached samples. However, the influence of membrane soiling andcleaning on roof heat gain is better gauged by variations in solarabsorptance. Relative solar absorptances (indicating solar heat gainrelative to that of the unsoiled membrane) ranged from 1.4 to 3.5 for thesoiled samples; 1.1 to 3.1 for the wiped samples; 1.0 to 2.0 for therinsed samples; 1.0 to 1.9 for the washed samples; and 0.9 to 1.3 for thebleached samples.

Roof shading and wall glazing techniques for reducing peak building heating and cooling loads. Final report  

SciTech Connect

The roof shading device proved to be effective in reducing peak building cooling loads under both actual testing conditions and in selected computer simulations. The magnitude of cooling load reductions varied from case to case depending on individual circumstances. Key variables that had significant impacts on its thermal performance were the number of months of use annually, the thermal characteristics of the roof construction, hours of building use, and internal gains. Key variables that had significant impacts upon economic performance were the costs of fuel energy for heating and cooling, and heating and cooling equipment efficiency. In general, the more sensitive the building is to climate, the more effective the shading device will be. In the example case, the annual fuel savings ($.05 psf) were 6 to 10% of the estimated installation costs ($.50 to .75 psf). The Trombe wall installation at Roxborough High School proved to be effective in collecting and delivering significant amounts of solar heat energy. It was also effective in conserving heat energy by replacing obsolete windows which leaked large amounts of heat from the building. Cost values were computed for both solar energy contributions and for heat loss reductions by window replacement. Together they amount to an estimated three hundred and ninety dollars ($390.00) per year in equivalent electric fuel costs. When these savings are compared with installation cost figures it is apparent that the Trombe wall installation as designed and installed presents a potentially cost-effective method of saving fuel costs. The study results indicate that improved Trombe wall efficiency can be achieved by making design and construction changes to reduce or eliminate outside air leakage into the system and provide automatic fan control.

GREEN ICT: How can ICT help to go Green Buildings?  

E-Print Network (OSTI)

The worldwide growth in the use of Information and Communications Technology ICT products has had both positive and negative effects. Electronics enable us to make information exchange quicker and easier; reduce our need to physically move people, products, information, and allow us to cut traffic, but increase pollution and increase the negative ecological impact. Recently, an argumentative issue refers indirectly to the benefit of ICT to go green and decrease the negative ecological impact. In the near future, ICT will also play a critical role in supporting the necessary paradigm shifts within the green sector towards more sustainable generation. With this in mind, a discussion of how the proposed consumers can achieve green savings on top of the efficiency gains resulting from automated systems is represented.

Government Purchasing Government Purchasing Community Choice Aggregation Disclosure Policies Green Power Policies Net Metering Policies Government Purchasing A number of governments, at both the federal, state, and local level, have established targets or goals for the amount of green power that their facilities should use. At the federal level, the Energy Policy Act of 2005 requires that federal government purchase 3% renewable energy in fiscal years 2007-2009, 5% in fiscal years 2010-2012, and 7.5% in fiscal year 2013 and thereafter. In January 2007, Executive Order 13423 established that at least half of the mandated renewable energy come from generation built after January 1, 1999. State governments, including Connecticut, Illinois, Indiana, Maine, Maryland, Massachusetts, New York, Pennsylvania, and Wisconsin, have committed to purchasing green power.

Some Anisotropic Viscoelastic Green Functions  

E-Print Network (OSTI)

In this paper, we compute the closed form expressions of elastody- namic Green functions for three different viscoelastic media with simple type of anisotropy. We follow Burridge et al. [Proc. Royal Soc. of London. 440(1910): (1993)] to express unknown Green function in terms of three scalar functions $\\phi_i$, by using the spectral decomposition of the Christoffel tensor associated with the medium. The problem of computing Green function is, thus reduced to the resolution of three scalar wave equations satisfied by $\\phi_i$, and subsequent equations with $\\phi_i$ as source terms. To describe viscosity effects, we choose an empirical power law model which becomes well known Voigt model for quadratic frequency losses.

Results and Recaps Results and Recaps Green Racing Initiative - 2011 Season The Green Racing Initiative, managed by Argonne for the U.S. Department of Energy (DOE), has become an integral part of the American Le Mans Series (ALMS). The 2011 season continued the growth and acceptance of green racing activities in the Series. In August 2011, ALMS announced that it would implement Green Racing 2.0 in future races. Renewable Fuel Use The 2011 ALMS season saw the use of non-petroleum and renewable fuels become dominant. Every Green Challenge victory in the Gran Turismo (GT) category and five out of nine victories in the Le Mans Prototype (LMP) category were won by a car using advanced fuels. Underlining the significance of this movement to advanced renewable fuels is that teams and engineers from a
