Cooling energy measurements of houses with attics containing radiant barriers  

Science Conference Proceedings (OSTI)

Tests were conducted by Oak Ridge National Laboratory (ORNL) to determine the magnitude of the energy savings brought about by installing radiant barriers in the attics of single-family houses. The radiant barrier used for this test was a product with two reflective aluminum surfaces on a kraft paper base. The radiant barrier has the potential to reduce the radiant heat transfer component impinging on the fiberglass attic insulation. Working as a system in conjunction with an air space, the radiant barrier could theoretically block up to 95% of far-infrared radiation heat transfer. The results showed a savings in the cooling loads of 21% when the radiant barrier was laid on top of the attic fiberglass insulation and 13% with the radiant barrier attached to the underside of the roof trusses. The savings in electrical consumption was 17% and 9%, respectively.

The radiant barrier used for this test was a product with two reflective aluminum surfaces on a kraft paper base. The radiant barrier has the potential to reduce the radiant heat transfer component impinging on the fiberglass attic insulation. Working as a system in conjunction with an air space, the radiant barrier could theoretically block up to 95% of far-infrared radiation heat transfer. The experiment was conducted in three unoccupied research houses that are operated by ORNL. One house was used as the control house (no barrier was installed), while the other two were used to test the two different methods for installing the radiant barriers. In one house, the barrier was laid on top of the attic fiberglass batt insulation, and in the other house, the barrier was attached to the underside of the roof trusses. The attics of all three houses were insulated with kraft paper faced nominal R-19 fiberglass batt insulation. The results showed a savings in the cooling loads of 21% when the radiant barrier was laid on top of the attic fiberglass insulation and 13% with the radiant barrier attached to the underside of the roof trusses. The savings in electrical consumption was 17% and 9%, respectively. The electrical consumption data and the cooling load data indicated that the most effective way of installing the foil was to lay it on top of the fiberglass batt insulation. The radiant barriers reduced the measured peak ceiling heat fluxes by 39% for the case where the barrier was laid on top of the attic fiberglass insulation. The radiant barrier reduced the integrated heat flows from the attic to house by approximately 30-35% over a 7-day time period.

Analysis of annual energy savings due to radiant barriers  

Science Conference Proceedings (OSTI)

Radiant barriers are receiving increasing attention as an energy conservation measure for residential buildings, especially for warmer climates. They are being actively promoted for use in residential attics, sometimes with exaggerated claims about savings in utility bills that will results from their installation. In order to provide consumers with factual information that would assist them in deciding upon an investment in a radiant barrier, the Department of Energy, along with an industry advisory panel, has developed a Radiant Barrier Fact Sheet. A major part of this fact sheet is estimates of energy savings that might be expected from radiant barriers in various climates. This paper presents the details of the methodology underlying the energy savings estimates, and gives a summary of values listed in the Fact Sheet. The energy savings estimates were obtained from calculations using a detailed attic thermal model coupled with DOE-2.1C. A life cycle cost analysis was performed to estimate the present value savings on utility fuel costs. The results show that the fuel cost savings vary significantly with the level of conventional insulation already in the attic and from one climate to another.

Dust and Ventilation Effects on Radiant Barriers: Cooling Season Energy Measurements  

Science Conference Proceedings (OSTI)

This study on the effects of attic ventilation area and type and dust buildup on horizontal and truss radiant barriers in insulated homes can help utilities reduce cooling season electric energy requirements. Increasing the ventilation area ratio and changing ventilation types had little effect on radiant barrier performance. Dust did degrade performance, but insulated homes with radiant barriers still had lower energy requirements than those without radiant barriers.

Radiant energy collection and conversion apparatus and method  

SciTech Connect

The apparatus for collecting radiant energy and converting same to alternate energy form includes a housing having an interior space and a radiation transparent window allowing, for example, solar radiation to be received in the interior space of the housing. Means are provided for passing a stream of fluid past said window and for injecting radiation absorbent particles in said fluid stream. The particles absorb the radiation and because of their very large surface area, quickly release the heat to the surrounding fluid stream. The fluid stream particle mixture is heated until the particles vaporize. The fluid stream is then allowed to expand in, for example, a gas turbine to produce mechanical energy. In an aspect of the present invention properly sized particles need not be vaporized prior to the entrance of the fluid stream into the turbine, as the particles will not damage the turbine blades. In yet another aspect of the invention, conventional fuel injectors are provided to inject fuel into the fluid stream to maintain the proper temperature and pressure of the fluid stream should the source of radiant energy be interrupted. In yet another aspect of the invention, an apparatus is provided which includes means for providing a hot fluid stream having hot particles disbursed therein which can radiate energy, means for providing a cooler fluid stream having cooler particles disbursed therein, which particles can absorb radiant energy and means for passing the hot fluid stream adjacent the cooler fluid stream to warm the cooler fluid and cooler particles by the radiation from the hot fluid and hot particles.

Radiant barriers in houses: Energy, comfort, and moisture considerations in a northern climate  

Science Conference Proceedings (OSTI)

The purpose of this study was to determine the conditions under which radiant barrier utilization in attics is appropriate technology in building construction for a northern climate in Utah. A sample of 12 appropriate houses with radiant barriers were selected using predetermined criteria. Another 12 houses without radiant barriers were selected as a control sample and paired with the first 12 houses using predetermined criteria. The research involved three different types of data and analyses. First, a questionnaire survey was completed by the occupants of the 12 sample houses, with radiant barriers. The survey included such factors as: (1) comfort, (2) energy, and (3) potential increased moisture content as perceived by the occupants. Second, a t-test was used to calculate the statistical comparison of utility usage between the 12 sample houses with radiant barriers and the 12 control houses without radiant barriers. Third, the moisture content of the wood framing above and below the radiant barriers was measured over a three month period during the winter months. Data analysis indicated: (1) occupants did perceive that more comfort resulted from the installation of radiant barriers, (2) occupants did not observe additional moisture artifacts after the installation of radiant barriers, (3) occupants did perceive cost savings from utility benefits resulting from the use of radiant barriers, especially in cooling the houses in summer, (4) there was no significant difference between utility usage of houses with radiant barriers and houses without radiant barriers, (5) the moisture content in the ceiling joists of all 24 houses, except one, had a moisture content measurement less than eight percent, and (6) houses with radiant barriers have higher humidity levels within the living space than houses without radiant barrier installation.

Radiant energy receiver having improved coolant flow control means  

DOE Patents (OSTI)

An improved coolant flow control for use in radiant energy receivers of the type having parallel flow paths is disclosed. A coolant performs as a temperature dependent valve means, increasing flow in the warmer flow paths of the receiver, and impeding flow in the cooler paths of the receiver. The coolant has a negative temperature coefficient of viscosity which is high enough such that only an insignificant flow through the receiver is experienced at the minimum operating temperature of the receiver, and such that a maximum flow is experienced at the maximum operating temperature of the receiver. The valving is accomplished by changes in viscosity of the coolant in response to the coolant being heated and cooled. No remotely operated valves, comparators or the like are needed.

Tests were conducted by Oak Ridge National Laboratory (ORNL) to determine the magnitude of the heating energy savings achieved by installing attic radiant barriers. The radiant barriers used for the test consist of a material with two reflective aluminum surfaces on a kraft paper base. The experiment was conducted in three unoccupied research houses operated by ORNL. Two variations in the installation of radiant barriers were studied.

In one house, the radiant barrier was laid on top of the attic fiberglass batt insulation, and in the other house, the barrier was attached to the underside of the roof trusses. The attics of all three houses were insulated with a kraft-paper-faced R-19 fiberglass batt insulation. The winter test with the radiant barrier showed that the horizontal barrier was able to save space-heating electical energy in both the resistance and heat pump modes amounting to 10.1% and 8.5%, respectively. The roof truss radiant barrier increased consumption by 2.6% in the resistance mode and 4.0% in the heat pump mode. The horizontal orientation of the radiant barrier is the more energy-effective method of installation.

Energy measurements of attic radiant barriers installed in single-family houses  

Science Conference Proceedings (OSTI)

Testing was conducted by the Oak Ridge National Laboratory to determine the energy savings attributable to radiant barriers installed in attics of unoccupied single-family houses. Three levels of fiberglass attic insulation (R-11 ,R-19, and R-30) were tested with two types of barrier installation (horizontal and truss). The results showed that horizontally installed radiant barriers were more effective than truss barriers in reducing heating and cooling loads. Measured cooling load reductions ranged form 0 to 22% (compared to same attic insulation insulation R-value with no radiant barrier) and heating load changes from /plus/4% to /minus/10% were measured (compared to same attic insulation R-value with no radiant barrier). Radiant barriers appeared to decrease the heating and cooling loads more when lesser amounts of insulation (R-11 and R-19) were present in an attic. Minimal changes were measured when R-30 was present in an attic. Long-term effects of dust on the performance of radiant barriers as well as the effects of moisture condensing on the surface of a radiant barrier during cold winter temperatures remain unanswered.

Energy, cost, and CO 2 emission comparison between radiant wall panel systems and radiator systems  

E-Print Network (OSTI)

The main goal of this paper is to evaluate the possibility of application or replacement of radiators with low-temperature radiant panels. This paper shows the comparison results of operations of 4 space heating systems: the low-temperature radiant panel system without any additional thermal insulation of external walls (PH-WOI), the low-temperature radiant panel system with additional thermal insulation of external walls (PH-WI), the radiator system without any additional thermal insulation of external walls (the classical heating system) (RH-WOI), and the radiator system with additional thermal insulation of external walls (RH-WI). The operation of each system is simulated by software EnergyPlus. The investigation shows that the PH-WI gives the best results. The RH-WOI has the largest energy consumption, and the largest pollutant emission. However, the PH-WI requires the highest investment.

Where radiant barriers really shine  

Science Conference Proceedings (OSTI)

Manufactures of radiant barrier materials claim their products significantly cut cooling costs by reducing summertime radiant heat gain through attics and ceilings. A new study confirms that radiant barriers can indeed conserve cooling energy. However, the study`s authors found that radiant barriers are much more effective at reducing energy losses from attic air conditioner duct runs than at directly lowering heat transfer through the attic floor into conditioned living space. Furthermore the study demonstrated that radiant barrier savings can be significant even in a new well-weatherized house and that these saving may justify specifying smaller capacity cooling systems. This article discusses the findings of the study.

Cooling season energy measurements of dust and ventilation effects on radiant barriers  

Science Conference Proceedings (OSTI)

Cooling season tests were conducted in three unoccupied ranch-style houses in Karns, Tennessee, to determine the effects on attic radiant barrier performance incurred by changes in attic ventilation area ratio, attic ventilation type, and the buildup of dust on horizontal radiant barriers. All three houses had R-19 fiberglass batt insulation in their attics. Horizontal radiant barriers were artificially dusted and the dusted barriers showed measurable performance degradations, although the dusted barriers were still superior to no radiant barriers. Dust loadings of 0.34 and 0.74 mg/cm{sup 2} reduced a clean radiant barrier surface emissivity of 0.055 to 0.125 and 0.185, respectively. Total house cooling load increases amounted to 2.3 and 8.4% compared to house loads with clean horizontal barriers, respectively. When compared to R-19 with no horizontal radiant barrier conditions, the dusted horizontal radiant barriers reduced cooling loads by about 7%. Testing showed that increasing the attic ventilation area ratio from the minimum recommended of 1/300 (1 ft{sup 2} of effective ventilation area per 300 ft{sup 2} of attic area) to 1/150 had little if any effect on the house cooling load with either truss or horizontal barriers present in the attics. Radiant barriers, however, still reduced the house cooling load. 18 refs., 17 figs., 26 tabs.

There was essentially no difference in house cooling load reduction between either ridge/soffit or gable/soffit vent type with a truss radiant barrier, as both reduced cooling loads by about 8% when compared to no radiant barrier conditions. The attic-ventilation-type testing was done with a ventilation area ratio of 1/150.

Energy measurements of single-family houses with attics containing radiant barriers  

Science Conference Proceedings (OSTI)

Radiant barriers were tested in attics of three unoccupied research houses which are located near Knoxville, Tennessee. The prime purpose of the testing was to determine the interaction, if any, between two types of radiant barriers, horizontal (barrier laid on top of attic insulation) and truss (barrier attached to underside of roof trusses), and three levels of fiberglass-batt attic insulation, R-11, R-19, and R-30. Testing of radiant barriers with R-19 fiberglass-batt attic insulation was done at the houses in the summer of 1985 and in the winter of 1985-86. The R-11 and R-30 testing was done in the summer of 1986. These results showed that horizontal barriers were more effective than truss barriers in reducing house cooling and heating loads. The summer of 1986 testing showed that increasing the attic insulation from R-11 to R-30 reduced the house cooling load (Btu) by approximately 16%. Adding a horizontal barrier to R-11 also reduced the cooling load compared to R-11 with no barrier by about 16%, while a truss barrier reduced it by 11%. A horizontal barrier with R-30 only reduced the cooling load by 2% compared to R-30 with no barrier, while an increase in the cooling load of 0.7% was measured with a truss barrier and R-30. Radiant barriers were not effective in reducing house cooling loads when R-30 attic insulation was present. The results from the summer of 1985 were integrated into the latest work through the use of a modeling effort using the building load simulation program, DOE-2.1B. This showed that R-19 insulation in conjunction with a horizontal barrier was (for Knoxville) the most effective barrier/insulation combination and could reduce the house cooling load by 25.1% compared to R-11 with no barrier.

Thermal radiant exitance model performance: Soils and forests  

DOE Green Energy (OSTI)

Models of surface temperatures of two land surface types based on their energy budgets were developed to simulate the effects of environmental factors on thermal radiant exitance. The performance of these models is examined in detail. One model solves the non-linear differential equation for heat diffusion in solids using a set of submodels for surface energy budget components. The model performance is examined under three desert conditions thought to be a strong test of the submodels. The accuracy of the temperature predictions and submodels is described. The accuracy of the model is generally good but some discrepancies between some of the submodels and measurements are noted. The sensitivity of the submodels is examined and is seen to be strongly controlled by interaction and feedback among energy components that are a function of surface temperature. The second model simulates vegetation canopies with detailed effects of surface geometry on radiant transfer in the canopy. Foliage solar absorption coefficients are calculated using a radiosity approach for a three layer canopy and long wave fluxes are modeled using a view factor matrix. Sensible and latent heat transfer through the canopy are also simulated using, nearby meteorological data but heat storage in the canopy is not included. Simulations for a coniferous forest canopy are presented and the sensitivity of the model to environmental inputs is discussed.

HVAC Equipment Design Options for Near-Zero-Energy Homes - Scoping Assessment of Radiant Panel Distribution System Options  

Science Conference Proceedings (OSTI)

Although the energy efficiency of heating, ventilating, and air-conditioning (HVAC) equipment has increased substantially in recent years, new approaches are needed to continue this trend. Conventional unitary equipment and system designs have matured to a point where cost-effective, dramatic efficiency improvements that meet near-zero-energy housing (NZEH) goals require a radical rethinking of opportunities to improve system performance. The large reductions in HVAC energy consumption necessary to support the NZEH goals require a systems-oriented analysis approach that characterizes each element of energy consumption, identifies alternatives, and determines the most cost-effective combination of options. In particular, HVAC equipment must be developed that addresses the range of special needs of NZEH applications in the areas of reduced HVAC and water heating energy use, humidity control, ventilation, uniform comfort, and ease of zoning. In FY05, ORNL conducted a scoping-level assessment of HVAC system options for NZEH homes (Baxter 2005). That report examined some twenty HVAC and water heating (HVAC/WH) systems in two 1800 ft2 houses--one constructed to Building America Research Benchmark standards and one a prototype NZEH. Both centrally ducted and two-zone systems were examined in that study. The highest scoring options using the ranking criteria described in that report were air-source and ground-source integrated heat pumps (IHP), and these were selected by DOE for further development. Among the feedback received to the FY05 report was a comment that systems using radiant panel (floor or ceiling) distribution options were not included among the system examined. This present report describes an assessment of a few such radiant panel systems under the same analysis and ranking criteria used in Baxter (2005). The rankings of the radiant system options reported herein are based on scoring by the team of building equipment researchers at ORNL. It is DOE's prerogative to revisit the criteria and obtain scoring from additional perspectives as part of its decision making process. If the criteria change, the ORNL team will be happy to re-score.

Radiant barrier applications: Symposium and workshop proceedings  

Science Conference Proceedings (OSTI)

Electric utilities and their customers are continually looking for ways to improve the thermal integrity of buildings. Radiant barrier systems can reduce summer air conditioning loads by reducing radiant heat transfer in attics. EPRI conducted two programs to help utilities with radiant barriers. A Symposium and Workshop were conducted in April 1988. The Symposium reviewed the state of the art in radiant barriers. The Workshop brought industry experts together to identify research needs for radiant barriers. The Workshop found that research is needed in six major areas. Listed in order of importance these are: (1) Field and laboratory testing, (2) Materials research, (3) Modeling, (4) Materials standards, (5) Economic issues, and (6) Installation methods. The leading research topics within these six major areas in order of importance include:(1) Modeling to fill voids in existing field data and aid in the development of performance standards, (2) Calculation of energy savings for various configurations, (3) Analysis of existing data to better understand radiant barrier performance, (4) Assessment of the effect of dust accumulation on performance, (5) Development of standard testing procedures, (6) Development of systems standards, (7) Measurement of changes in the emissivity of radiant barrier materials with time, (8) Determination of the possibility of moisture accumulation under horizontal radiant barriers during heating season operation, (9) Ventilation effects, (10) Configuration testing, (11) Costs of new and retrofit applications, and (12) Characterization of side effects. 34 refs., 5 figs.

Heating energy measurements of single-family houses with attics containing radiant barriers in combustion with R-11 and R-30 ceiling insulation  

Science Conference Proceedings (OSTI)

Tests were conducted by Oak Ridge National Laboratory to determine the heating energy performance of two levels of fiberglass-batt attic insulation (R-11 and R-30) in combination with truss and horizontally installed radiant barriers. The tests, a continuation of work started in the summer of 1985, were conducted in three unoccupied ranch-style houses in Karns, Tennessee, during the winter of 1986-87. The measured results of the heating tests showed that a horizontal radiant barrier used with R-11 attic insulation reduced the house heating load by 9.3% compared with R-11 with no radiant barrier, while a truss barrier showed essentially no change in the heating load. Horizontal and truss barriers each reduced the heating load by 3.5% when added to R-30 attic insulation. Moisture condensed on the bottom of the horizontal barrier during cold early morning weather but usually dissipated in the warmer afternoon hours at Karns and left no accumulation in the insulation. Depending on the level of attic insulation, an annual heating and cooling HVAC savings ranging from $5 to $65 is estimated to be attainable when a radiant barrier is installed in the attic at Karns. 8 refs., 64 figs., 18 tabs.

Optics and materials research for controlled radiant energy transfer in buildings. Final technical report  

DOE Green Energy (OSTI)

The primary objective of this project was to perform the optics and materials research necessary to identify and solve the technical problems associated with fabricating durable, variable reflectivity electrochromic windows for energy efficient buildings and vehicles. The research performed at the Tufts Electro-Optics Technology Center (EOTC) has identified and solved nearly all the significant problems, as discussed below in this final technical report. There still remains, however, one important problem to be solved--i.e., to better understand the science of deposition processes and thereby develop and optimize one or more production-worthy deposition processes that could be used for the practical production of affordable, variable reflectivity electrochromic windows. Therefore, it is recommended that such studies be carried out with the goals of: (1) determining the probable practical limits of performance; and, very importantly, (2) to develop and optimize deposition processes that could be used for the practical production of affordable electrochromic windows.

The Oklahoma Field Test: Air-conditioning electricity savings from standard energy conservation measures, radiant barriers, and high-efficiency window air conditioners  

SciTech Connect

A field test Involving 104 houses was performed in Tulsa, Oklahoma, to measure the air-conditioning electricity consumption of low-income houses equipped with window air conditioners, the reduction in this electricity consumption attributed to the installation of energy conservation measures (ECMS) as typically installed under the Oklahoma Weatherization Assistance Program (WAP), and the reduction achieved by the replacement of low-efficiency window air conditioners with high-efficiency units and the installation of attic radiant barriers. Air-conditioning electricity consumption and indoor temperature were monitored weekly during the pre-weatherization period (June to September 1988) and post-weatherization period (May to September 1989). House energy consumption models and regression analyses were used to normalize the air-conditioning electricity savings to average outdoor temperature conditions and the pre-weatherization indoor temperature of each house. The following conclusions were drawn from the study: (1) programs directed at reducing air-conditioning electricity consumption should be targeted at clients with high consumption to improve cost effectiveness; (2) replacing low-efficiency air conditioners with high-efficiency units should be considered an option in a weatherization program directed at reducing air-conditioning electricity consumption; (3) ECMs currently being installed under the Oklahoma WAP (chosen based on effectiveness at reducing space-heating energy consumption) should continue to be justified based on their space-heating energy savings potential only; and (4) attic radiant barriers should not be included in the Oklahoma WAP if alternatives with verified savings are available or until further testing demonstrates energy savings or other benefits in this typo of housing.

Analysis of annual thermal and moisture performance of radiant barrier systems

This report summarizes a project to model the annual thermal and moisture performance of radiant barrier systems installed in residential attics. A previously developed model for the thermal performance of attics with radiant barriers was modified to allow estimates of moisture condensation on the underside of radiant barriers that are laid directly on top of existing attic insulation. The model was partially validated by comparing its predictions of ceiling heat flows and moisture condensation with data and visual observations made during a field experiment with full-size houses near Knoxville, Tennessee. Since the model predictions were found to be in reasonable agreement with the experimental data, the models were used to estimate annual energy savings and moisture accumulation rates for a wide variety of climatic conditions. The models results have been used to identify locations where radiant barriers are cost effective and also where radiant barriers have potential for causing moisture problems. 58 refs., 20 figs., 32 tabs.

Development of a Transient Heat and Mass Transfer Model of Residential Attics to Predict Energy Savings Produced by the Use of Radiant Barriers  

E-Print Network (OSTI)

A transient heat and mass transfer model was developed to predict ceiling heat gain/loss through the attic space in residences and to accurately estimate savings in cooling and heating loads produced by the use of radiant barriers. The model accounted for transient conduction, convection and radiation and incorporated moisture and air transport across the attic. Environmental variables such as solar loads on outer attic surfaces and sky temperatures were also estimated. The model was driven by hourly weather data which included: time, outdoor air temperature, horizontal sun and sky radiation, wind speed and direction, relative humidity (dew point), and cloud cover data. The outputs of the model were ceiling heat fluxes, inner and outer heat fluxes from all surfaces, inner and outer surface temperatures and attic air temperatures. Transient conduction was modeled using response factors. Response factors were calculated for each attic component based on construction type. Convective heat transfer was modeled using flat plate correlations found in the literature and radiative heat transfer was modeled using radiation enclosure theory. Moisture was incorporated via a condensation/evaporation model. A new procedure was developed to account for attic air stratification. Both forced and natural attic ventilation patterns were added to the model for three types of louver combination arrangements. An iterative technique was used to solve a set of simultaneous heat balance equations. The model predictions were compared to experimental data gathered throughout a three year experimental effort of side-by-side testing of attics retrofit with radiant barriers. The model was compared to the experimental data for a variety of situations which included: different attic insulation levels, various attic airflow rates, cooling and heating seasons, and different radiant barrier orientations. The model predicted ceiling heat flows within 10% for most cases. The model was used to run simulations and parametric studies under a diversity of climates, insulation levels and attic airflow patterns. Model predictions and results were presented on the basis of savings produced by the use of radiant barriers. Hourly, daily, and seasonal predictions by the model were in excellent agreement with observed experimental data and with literature.

The Influence of Dust on the Absorptivity of Radiant Barriers  

E-Print Network (OSTI)

The purpose of this project was to model and quantify the increase of the absorptivity of radiant barriers caused by the accumulation of dust on the surface of radiant barriers. This research was the continuation of a previous work by the author at Texas A&M University in which a radiation energy balance inside the attic enclosure was developed. The particles were considered as flat, circular planes, all having the same radii. That early model showed that there was a linear relationship between the fraction of area of the foil covered by dust and the mean absorptivity of the dusty radiant barrier. In the present work, it was found that the assumption of treating the dust particles as plane circles, underestimated the effective area of the particles by about 20%. Experimental measurements indicated that dust particles achieved the same temperature as the radiant barrier. The new model used the linear relationship just described, and simulated the dust particles as flat circular planes having random radii and laying in random locations within the radiant barrier surface. The new model calculated the fraction of radiant barrier area covered by particles using a digital array in which the clean barrier was represented as zeroes and the dust particles were represented as a set of ones appropriately dimensioned inside the array. The experimentation used natural dust and Arizona Road Test Dust. Using an infrared emissometer, the emissivities (absorptivities) of the clean and dusty barriers were measured and using an electronic scale, the dust loading was measured. An electron microscope was used to experimentally find the fraction of radiant barrier covered by the dust particles to correlate the experimentally found absorptivity with the experimentally found fraction of dust coverage. The limited experimental data available were also used to correlate the absorptivity of the dusty radiant barrier with the time of dust accumulation and the location of the barrier inside the attic. A linear relationship between the absorptivity and the time of dust accumulation was found that can be applied to predict future barrier effectiveness based upon the rate of dust accumulation for a given location.

Indoor Humidity Analysis of an Integrated Radiant Cooling and Desiccant Ventilation System  

E-Print Network (OSTI)

Radiant cooling is credited with improving energy efficiency and enhancing the comfort level as an alternative method of space cooling in mild and dry climates, according to recent research. Since radiant cooling panels lack the capability to remove latent heat, they normally are used in conjunction with an independent ventilation system, which is capable of decoupling the space sensible and latent loads. Condensation concerns limit the application of radiant cooling. This paper studies the dehumidification processes of solid desiccant systems and investigates the factors that affect the humidity levels of a radiantly cooled space. Hourly indoor humidity is simulated at eight different operating conditions in a radiantly cooled test-bed office. The simulation results show that infiltration and ventilation flow rates are the main factors affecting indoor humidity level and energy consumption in a radiantly cooled space with relatively constant occupancy. It is found that condensation is hard to control in a leaky office operated with the required ventilation rate. Slightly pressurizing the space is recommended for radiant cooling. The energy consumption simulation shows that a passive desiccant wheel can recover about 50% of the ventilation load.

In this study, ceiling radiant cooling panel, mechanical ventilation with fan coil unit (FCU) and 100% fresh air are used. Temperature sensors are located at different locations inside the conditioned space in order to sense dry bulb temperatures, relative humidity to compare it with standard ASHRAE comfort values. The present investigation indicates that the radiant cooling system not only improves the indoor air quality but also reduces the building energy consumption in the conditioned space.

Energy and waste reduction in the wood fiber and fuel industry utilizing a long wave length catalytic infrared drying system. Progress report No.4, January 1--March 31, 1998  

SciTech Connect

During the past quarter significant headway was made on the project. The design and fabrication of the materials handling system by the subcontractor, Cat-Tech Industries, was completed in late January and was shipped in February to Catalytic Industrial System (CIS) Kansas facility. Unfortunately a part shipped directly from the manufacturer, for mating in Kansas to the unit, was determined to be the wrong size and nearly a month was lost in the process of ordering and receiving the correct parts. In early March the system was ready for agitation testing and performed perfectly. Design of the air circulation system was completed in late March and fabrication and installation of that element is expected to be completed this week (April 15--22). The insulation panels have been designed and ordered and are expected to be on site and ready for installation the last week of April. In a series of conference phone calls, it was decided to increase the amount of infrared energy input in Zone 1 (the first one-third of the 30 foot unit) of the dryer. These zones are presently being redesigned and fabricated and will likely be installed by the 10th of May. Product testing is expected to commence around the 15--20 of May. Work on the testing protocol was held in check while the discussion on increasing the total energy input was transpiring. It is scheduled to restart on or about May 1.

Radiant vessel auxiliary cooling system  

DOE Patents (OSTI)

In a modular liquid-metal pool breeder reactor, a radiant vessel auxiliary cooling system is disclosed for removing the residual heat resulting from the shutdown of a reactor by a completely passive heat transfer system. A shell surrounds the reactor and containment vessel, separated from the containment vessel by an air passage. Natural circulation of air is provided by air vents at the lower and upper ends of the shell. Longitudinal, radial and inwardly extending fins extend from the shell into the air passage. The fins are heated by radiation from the containment vessel and convect the heat to the circulating air. Residual heat from the primary reactor vessel is transmitted from the reactor vessel through an inert gas plenum to a guard or containment vessel designed to contain any leaking coolant. The containment vessel is conventional and is surrounded by the shell.

Radiant Barrier Performance during the Heating Season  

E-Print Network (OSTI)

Results of winter experiments conducted in Central Texas are presented. The experiments were side-by-side tests using two identical 144 ft2 houses which responded similarly to weather variations prior to any retrofits. Two radiant barrier orientations were tested, horizontal barrier and barrier against the rafters, in vented and non-vented attics. The results compiled in this paper are for attics with R-19 fiberglass insulation. The data showed that radiant barriers were still effective during the winter season. During a typical day radiant barriers prevented approximately 9-17 percent of the indoor heat from escaping into the attic. No significant difference in moisture accumulation was detected in the attic with the radiant barrier.

Radiant cooling in US office buildings: Towards eliminating the perception of climate-imposed barriers  

Science Conference Proceedings (OSTI)

Much attention is being given to improving the efficiency of air-conditioning systems through the promotion of more efficient cooling technologies. One such alternative, radiant cooling, is the subject of this thesis. Performance information from Western European buildings equipped with radiant cooling systems indicates that these systems not only reduce the building energy consumption but also provide additional economic and comfort-related benefits. Their potential in other markets such as the US has been largely overlooked due to lack of practical demonstration, and to the absence of simulation tools capable of predicting system performance in different climates. This thesis describes the development of RADCOOL, a simulation tool that models thermal and moisture-related effects in spaces equipped with radiant cooling systems. The thesis then conducts the first in-depth investigation of the climate-related aspects of the performance of radiant cooling systems in office buildings. The results of the investigation show that a building equipped with a radiant cooling system can be operated in any US climate with small risk of condensation. For the office space examined in the thesis, employing a radiant cooling system instead of a traditional all-air system can save on average 30% of the energy consumption and 27% of the peak power demand due to space conditioning. The savings potential is climate-dependent, and is larger in retrofitted buildings than in new construction. This thesis demonstrates the high performance potential of radiant cooling systems across a broad range of US climates. It further discusses the economics governing the US air-conditioning market and identifies the type of policy interventions and other measures that could encourage the adoption of radiant cooling in this market.

Performance Testing of Radiant Barriers  

E-Print Network (OSTI)

TVA has conducted a study to determine the effects of radiant barriers (RBI (i.e., material with a low emissivity surface facing an air space), when used with fiberglass, on attic heat transfer during summer and winter. This study employed five small test cells exposed to ambient conditions and having attics with gable and soffit vents. Three different RB configurations were tested and compared to the non-RR configuration. Heat flux transducers determined the heat transfer between the attic and conditioned space. The results showed that all RB con figurations significantly reduced heat gain through the ceiling during the summer. Reductions in heat gain during daylight and peak electric load hours were especially attractive. Roof temperatures for the RB configurations were only slightly higher than for the non-RB case. Heat transfer reductions for the RB configurations in the winter were smaller than those for the summer but were still significant in many, but not all, situations. Savings during night and peak electric load hours were especially attractive.

Reverberatory screen for a radiant burner  

DOE Patents (OSTI)

The present invention relates to porous mat gas fired radiant burner panels utilizing improved reverberatory screens. The purpose of these screens is to boost the overall radiant output of the burner relative to a burner using no screen and the same fuel-air flow rates. In one embodiment, the reverberatory screen is fabricated from ceramic composite material, which can withstand higher operating temperatures than its metallic equivalent. In another embodiment the reverberatory screen is corrugated. The corrugations add stiffness which helps to resist creep and thermally induced distortions due to temperature or thermal expansion coefficient differences. As an added benefit, it has been unexpectedly discovered that the corrugations further increase the radiant efficiency of the burner. In a preferred embodiment, the reverberatory screen is both corrugated and made from ceramic composite material.

Influence of Attic Radiant Barrier Systems on Air Conditioning Demand in an Utility Pilot Project  

E-Print Network (OSTI)

A utility monitoring project has evaluated radiant barrier systems (RBS) as a new potential demand site management (DSM) program. The study examined how the retrofit of attic radiant barriers can be expected to alter utility residential space conditioning loads. An RBS consists of a layer of aluminum foil fastened to roof decking or roof trusses to block radiant heat transfer between the hot roof surface and the attic below. The radiant barrier can significantly lower summer heat transfer to the attic insulation and to the cooling duct system. Both of these mechanisms have strong potential impacts on cooling energy use as illustrated in Figures 1 and 2. The pilot project involved installation of RBS in nine homes that had been extensively monitored over the preceding year. The houses varied in conditioned floor area from 939 to 2,440 square feet; attic insulation varied from R-9 to R-30. The homes had shingle roofs with varying degrees of attic ventilation. The radiant barriers were installed during the summer of 2000. Data analysis on the pre and post cooling and heating consumption was used to determine impacts on energy use and peak demand for the utility. The average cooling energy savings from the RBS retrofit was 3.6 kWh/day, or about 9%. The average reduction in summer afternoon peak demand was 420 watts (or about 16%).

The Super-Radiant Mechanism, Doorway States, and Nuclear Reactions  

SciTech Connect

In 1954 the possibility of forming a 'super-radiant' (SR) state in a gas of atoms confined to a volume of a size smaller than the wave length of radiation was suggested by Dicke. The atoms, with two levels, are coupled through their common radiation field. This indirect coupling leads to a redistribution of decay widths among unstable intrinsic states. A strongly decaying SR state is created at the expense of the rest of the states of the system. The connection of this mechanism to the notion of doorway states in low-energy nuclear reactions is discussed and applications to well known nuclear physics phenomena are presented.

Modeling of Residential Attics with Radiant Barriers  

E-Print Network (OSTI)

This paper gives a summary of the efforts at ORNL in modeling residential attics with radiant barriers. Analytical models based on a system of macroscopic heat balances have been developed. Separate models have been developed for horizontal radiant barriers laid on top of the insulation, and for radiant barriers attached to the bottom of the top chords of the attic trusses. The models include features such as a radiation interchange analysis within the attic space, convective coupling with the ventilation air, and sorption/desorption of moisture at surfaces facing the attic enclosure. The paper gives details of the models and the engineering assumptions that were made in their development. The paper also reports on the status of efforts that are underway to verify the models by comparing their predictions with the results of laboratory and field tests on residential attics and test cells, both with and without radiant barriers. Comparisons are given for a number of selected sets of experimental data. Suggestions are given for needed model refinements and additional experimental data. Plans for utilization of the models for extrapolation to seasonal and annual performance in a variety of climatic conditions are also described.

Thermal Performance Evaluation of Attic Radiant Barrier Systems Using the Large Scale Climate Simulator (LSCS)  

SciTech Connect

Application of radiant barriers and low-emittance surface coatings in residential building attics can significantly reduce conditioning loads from heat flow through attic floors. The roofing industry has been developing and using various radiant barrier systems and low-emittance surface coatings to increase energy efficiency in buildings; however, minimal data are available that quantifies the effectiveness of these technologies. This study evaluates performance of various attic radiant barrier systems under simulated summer daytime conditions and nighttime or low solar gain daytime winter conditions using the large scale climate simulator (LSCS). The four attic configurations that were evaluated are 1) no radiant barrier (control), 2) perforated low-e foil laminated oriented strand board (OSB) deck, 3) low-e foil stapled on rafters, and 4) liquid applied low-emittance coating on roof deck and rafters. All test attics used nominal RUS 13 h-ft2- F/Btu (RSI 2.29 m2-K/W) fiberglass batt insulation on attic floor. Results indicate that the three systems with radiant barriers had heat flows through the attic floor during summer daytime condition that were 33%, 50%, and 19% lower than the control, respectively.

Radiant heat transfer from storage casks to the environment  

SciTech Connect

A spent fuel storage cask must efficiently transfer the heat released by the fuel assemblies through the cask walls to the environment. This heat must be transferred through passive means, limiting the energy transfer mechanisms from the cask to natural convection and radiation heat transfer.. Natural convection is essentially independent of the characteristics of the array of casks, provided there is space between casks to permit a convection loop. Radiation heat transfer, however, depends on the geometric arrangement of the array of casks because the peripheral casks will shadow the interior casks and restrict radiant heat transfer from all casks to the environment. The shadowing of one cask by its neighbors is determined by a view factor that represents the fraction of radiant energy that leaves the surface of a cask and reaches the environment. This paper addresses the evaluation of the view factor between a centrally located spent fuel storage cask and the environment. By combining analytic expressions for the view factor of (1) infinitely long cylinders and (2) finite cylinders with a length-to-diameter ratio of 2 to represent spent fuel storage casks, the view factor can be evaluated for any practical array of spent fuel storage casks.

Experimental Study of the Floor Radiant Cooling System Combined with Displacement Ventilation  

E-Print Network (OSTI)

As a comfortable and energy-efficient air conditioning system, the application of floor radiant heating system is used increasingly greatly in the north of China. As a result, the feasibility of floor radiant cooling has gained more attention. To examine the thermodynamic performance of the floor radiant cooling system, we measured the operational conditions including the minimum floor surface temperature, the cooling capacity, and the indoor temperature field distribution under different outdoor temperatures in Beijing. Because the ground temperature changes with the mean temperature of the supplied and returned water and room temperature, the mean temperature of the supplied and retuned water was obtained. Finally, we analyzed the phenomenon of dewing and developed measures for preventing it. The dry air layer near the floor formed by a displacement ventilation system can effectively prevent dews on the surface of the floor in the wet and hot days in summer. In addition, for the sake of the displacement ventilation system, the heat transfer effect between floor and space is enhanced. Our analysis pointed out that floor radiant cooling system combined with displacement ventilation ensures good comfort and energy efficiency.

Comparative Testing of the Combined Radiant Barrier and Duct Models in the ESL's Code-Compliant Simulation Model  

E-Print Network (OSTI)

This report presents a study of the application of the radiant barrier / duct models to the DOE-2.1e simulation program based on the previous methods (eQuest version 3.55 and EnergyGauge version 2.42) and the comparison of the results of the ESLs model and the EnergyGauge program by the Florida Solar Energy Center (FSEC). Sensitivity analyses were performed by varying duct insulation level, supply duct area, return duct area, supply duct leakage, return duct leakage, and ceiling insulation levels. The results of sensitivity analyses show acceptable agreement versus the EnergyGauge program for duct insulation level, supply duct area, return duct area, supply duct leakage, and ceiling insulation level. Significant differences in the return duct leakage calculations were observed. These comparisons show the ESL model is more sensitive to return duct leakage than the EnergyGauge model Comparison of the results of the duct model for two cases (with radiant barrier and without radiant barrier) show acceptable agreements for the parameters of duct insulation, supply duct surface area, return duct surface area, supply duct leakage and ceiling insulation. The results of savings (with and without radiant barriers) indicate that the ESL model shows slightly more savings for all parameters. In terms of the sensitivity of the results, the ESL model also shows more sensitivity for all parameters except supply duct leakage.

Influence of Dust on the Emissivity of Radiant Barriers  

E-Print Network (OSTI)

A model of the radiant heat transfer in attics containing dusty radiant barriers was developed. The geometrical model was a triangular enclosure in which the temperatures of the enclosing surfaces were known. The dust particles were simulated as areas of diameter equal to the mean diameter of the real dust to be analyzed and an emissivity substantially larger than the emissivity of the radiant barrier. Several shape factors were calculated using shape factor algebra, including a procedure to find the shape factor between a small rectangle and a triangular surface perpendicular to the rectangular plane. The thermal model was developed using the "Net Radiation Method" in which the net heat exchange between the surfaces surrounding the enclosure was found by solving a system of equations that has as many equations as the number of surfaces involved in the calculations. This led to the necessity of solving a very large system of equations in order to account for the dust particles in a representative amount. The solution of the system of equations provided the heat flux for each element of the enclosure. Finally, replacing the radiant barrier and the dust particles for an equivalent surface corresponding to the dusty radiant barrier provided the means to calculate the emissivity of this dusty radiant barrier. The theoretical model was tested to assess its validity. The experimentation was carried out using a reflection emissometer to measure the increase of the emissivity of aluminum radiant barrier when known quantities of dust were artificially applied to it. The experimental results showed good agreement with the theoretical model. A linear relationship between the emissivity and the area of dust coverage was found. The simple relation developed can be used in future research which still has to deal with the determination of the area of dust coverage by using the geometrical model of dust superposition or other statistical model to simulate the random location of random size dust particles over the radiant barrier.

In the present paper, a kind of enclosed phase change material (PCM) used in solar and low-temperature hot water radiant floor heating is investigated. On the basis of obtaining the best performance of PCM properties, a new radiant heating structure of the energy storage floor is designed,which places heat pipes in the enclosed phase change material (PCM) layer, without concrete in it. The PCM thermal storage time is studied in relation to the floor surface temperature under different low-temperature hot water temperatures.

Analysis of Attic Radiant Barrier Systems Using Mathematical Models  

E-Print Network (OSTI)

During the past six years, the Florida Solar Energy Center (FSEC) has conducted extensive experimental research on radiant barrier systems (RBS). This paper presents recent research on the development of mathematical attic models. Two levels of modeling capability have been developed. A very simplified model based on ASHRAE procedures in used to study the sensitivity of RBS performance parameters, and a very detailed finite element model is used to study highly complex phenomena, including moisture adsorption and desorption in attics. The speed of the simple model allows a large range of attic parameters to be studies quickly, and the finite element model provides a detailed understanding of combined heat and moisture transport in attics. This paper concentrates on a parametric analysis of attic RBS using the simplified model. The development of the model is described, and results of the parametric analyses are presented and discussed. Preliminary results from the finite element model are also compared with measurements from a test attic to illustrate the effects of moisture adsorption and desorption in common attics.

Effect of attic ventilation on the performance of radiant barriers  

Science Conference Proceedings (OSTI)

The objective of the experiments was to quantify how attic ventilation would affect the performance of a radiant barrier. Ceiling heat flux and space cooling load were both measured. Results of side-by-side radiant barrier experiments using two identical 13.38 m[sup 2] (nominal) test houses are presented in this paper. The test houses responded similarly to weather variations. Indoor temperatures of the test houses were controlled to within 0.2 [degrees] C. Ceiling heat fluxes and space cooling load were within a 2.5 percent difference between both test houses. The results showed that a critical attic ventilation flow rate of 1.3 (1/sec)/m[sup 2] of the attic floor existed after which the percentage reduction in ceiling heat fluxes produced by the radiant barriers did not change with increasing attic airflow rates. The ceiling heat flux reductions produced by the radiant barriers were between 25 and 35 percent, with 28 percent being the percent reduction observed most often in the presence of attic ventilation. The space-cooling load reductions observed were between two to four percent. All results compiled in this paper were for attics with unfaced fiberglass insulation with a resistance level of 3.35 m[sup 2]K/W (nominal) and for a perforated radiant barrier with low emissivities (less than 0.05) on both sides.

Solar energy system  

SciTech Connect

A solar energy system is described for selectively absorbing or reflecting radiant energy entering through a window of a structure, the system comprising a window drape having a decorative side and a back side, and a removable liner adjacent the backside of the window drape. At least one side of the liner or window drape backside is a radiant energy reflecting surface and another of said sides is a radiant energy absorbing surface. Thus, depending upon the season of the year, the system may be arranged to selectively provide the appropriate surface to optimize or minimize the radiant energy maintained within the structure.

Base load fuel comsumption with radiant boiler simulation  

Science Conference Proceedings (OSTI)

The operating point of an oil fired radiant boiler, 580 Megawatt capacity, is critical in maximizing the availability, performance, reliability, and maintainability of a power producing system. Operating the unit above the design operating point causes outages to occur sooner than scheduled. When the boiler is operated below the design operating point, fuel is wasted because the quantity of fuel required to operate a radiant boiler is the same, whether the design setpoint is maintained or not. This paper demonstrates by means of simulation software that the boiler design setpoints is critical to fuel consumption and optimum output megawatts. A boiler with this capacity is used to provide a portion of the base load of an electric utility in order to sustain revenues and maintain reliable generation.

Thermal performance of clean horizontal radiant barriers under winter conditions: Laboratory measurements and mathematical modeling  

Science Conference Proceedings (OSTI)

Several field experiments have been performed on attic radiant barriers under winter conditions; however, most of them have been confined to the fairly mild climates of Florida, Oklahoma, and Tennessee. Only one field experiment in a very cold climate (Canada) has been performed. In addition, no previous laboratory experiments under winter conditions have been performed on an attic both with and without a radiant barrier. This paper presents the results of laboratory measurements of the thermal performance of clean horizontal radiant barriers in a simulated residential attic module under nighttime or low solar gain daytime winter conditions. Comparing tests under the same conditions with and without a radiant barrier shows that the addition of a clean horizontal radiant barrier to insulation at the R-22 to R-25 level decreases the ceiling heat flow by 6 to 8%. The experimental results were found to be in very good agreement with predictions made with a mathematical model for the thermal performance of attics.

CFD Simulation and Analysis of the Combined Evaporative Cooling and Radiant Ceiling Air-conditioning System  

E-Print Network (OSTI)

Due to such disadvantages as large air duct and high energy consumption of the current all- outdoor air evaporative cooling systems used in the dry region of Northwest China, as well as the superiority of the ceiling cooling system in improving thermal comfort and saving energy, a combined system is presented in this paper. It combines an evaporative cooling system with ceiling cooling, in which the evaporative cooling system handles the entire latent load and one part of the sensible loads, and the ceiling cooling system deals with the other part of sensible loads in the air-conditioned zone, so that the condensation on radiant panels and the insufficiency of cooling capacity can be avoided. The cooling water at 18? used in the cooling coils of ceiling cooling system can be ground water, tap water or the cooled water from cooling towers in the summer. This new air-conditioning system and existing all- outdoor air evaporative cooling system are applied to a project in the city of Lanzhou. Energy consumption analysis of the building is carried out using the energy consumption code. Velocity and temperature distribution in the air-conditioned zone is computed using CFD. According to the results, the energy consumption and indoor human thermal comfort of both systems are then compared. It is concluded that the new system occupies less building space, reduces energy consumption, improves indoor human thermal comfort and saves initial investment.

Efficient Low-Lift cooling with Radiant Distribution, Thermal Storage and Variable-Speed Chiller Controls  

DOE Green Energy (OSTI)

The U.S. Department of Energys Building Technologies Program goal is to develop cost-effective technologies and building practices that will enable the design and construction of net-zero energy buildings by 2025. To support this goal, Pacific Northwest National Laboratory evaluated an integrated technology that through utilization of synergies between emerging heating, ventilation and air conditioning systems can significantly reduce energy consumption in buildings. This set consists of thermal storage, dedicated outdoor air system, radiant heating/cooling with a variable speed low-lift-optimized vapor compression system. The results show that the low-lift cooling system provides significant energy savings in many building types and climates locations. This market represents well over half of the entire U.S. commercial building sector. This analysis shows that significant cooling system efficiency gains can be achieved by integrating low-lift cooling technologies. The cooling energy savings for a standard-performance building range from 37% to 84% and, for a high-performance building, from -9% to 70%.

Effects of Radiant Barrier Systems on Ventilated Attics in a Hot and Humid Climate  

E-Print Network (OSTI)

Results of side-by-side radiant barrier experiments using two identical 144 ft2 (nominal) test houses are presented. The test houses responded very similarly to weather variations prior to the retrofit. The temperatures of the test houses were controlled to within 0.3F. Ceiling heat fluxes were within 2 percent for each house. The results showed that a critical attic ventilation flow rate (0.25 CFM/ft2 ) existed after which the percentage reduction produced by the radiant barrier systems was not sensitive to increased airflows. The ceiling heat flux reductions produced by the radiant barrier systems were between 25 and 34 percent, with 28 percent being the reduction observed most often in the presence of attic ventilation. All results presented in this paper were for attics with R-19 unfaced fiberglass insulation and for a perforated radiant barrier with low emissivities on both sides.

Numerical heat transfer attic model using a radiant barrier system  

Science Conference Proceedings (OSTI)

A two-dimensional, steady-state finite-element model was developed to simulate the thermal effects of the application of an attic radiant barrier system (ARBS) inside a ventilated residential attic. The attic is ventilated using the exhaust air from an evaporative cooler. The study uses a {kappa}-{epsilon} turbulent model to describe the velocity and temperature distributions in the attic. The ambient temperature and solar isolation densities on the outside inclined attic surfaces are used as driving functions for the model. The model also included the appropriate heat exchange modes of convection and radiation on these outside surfaces. Several recirculation zones were visually observed in the attic flow pattern. Also, the use of the ARBS seems to lower the heat transfer through the ceiling by 25--30%, but this effect decreases significantly as the outside ventilation rates are increased through the attic space. The 2D model revealed some interesting temperature distributions along the attic surfaces that could not have been predicted by the one-dimensional models. The lower emissivity ARBS seems to raise the temperature of the inclined attic surfaces as well as the temperature of the exhausted ventilation air.

Economic Evaluation of Insulation/Radiant Barrier Systems for the State of Texas  

E-Print Network (OSTI)

This paper presents simulated performance of insulation/radiant barrier systems under different Texas climates. A transient heat and mass transfer model which predicts thermal performance of residential attics (Medina, 1992) was coupled with an "economic" subroutine. Simple payback periods were estimated which were based on current insulation and radiant barrier (RB) prices (materials and installation), and current and forecast electric rates. It was found that when the analyses were based solely on reductions of ceiling heat loads during the summer time, a combination of R-11 with RB was more effective than upgrading the insulation level to R-19. Similarly, adding a radiant barrier to an existing insulation level of R-19 proved more effective than upgrading to R-30. When heat gains to the cold air traveling inside A/C ducts (\\which are usually installed in attic spaces) were considered, all insulation/radiant barrier combinations showed faster payback periods than insulation upgrades, During the winter time, insulation upgrades proved to be more effective than insulation/radiant barrier combinations. The simple payback analyses presented herein include both summer and winter simulations.

Gas Phase Photoacoustic Spectroscopy in the long-wave IR using Quartz Tuning Forks and Amplitude Modulated Quantum Cascade Lasers  

Science Conference Proceedings (OSTI)

A paper to accompany a 20 minute talk about the progress of a DARPA funded project called LPAS. ABSTRACT: We demonstrate the performance of a novel long-wave infrared photoacoustic laser absorbance spectrometer for gas-phase species using an amplitude modulated (AM) quantum cascade (QC) laser and a quartz tuning fork microphone. Photoacoustic signal was generated by focusing the output of a Fabry-Perot QC laser operating at 8.41 micron between the legs of a quartz tuning fork which served as a transducer for the transient acoustic pressure wave. The QC laser was modulated at the resonant frequency of the tuning fork (32.8 kHz). This sensor was calibrated using the infrared absorber Freon-134a by performing a simultanious absorption measurement using a 35 cm absorption cell. The NEAS of this instrument was determined to be 2 x 10^-8 W cm^-1 /Hz^1/2 and the fundamental sensitivity of this technique is limited by the noise floor of the tuning fork itself.

Analysis in Support of the Radiant Barrier Fact Sheet 2010 Update  

Science Conference Proceedings (OSTI)

Quantifying the benefits of radiant barriers is complex because the benefits depend upon the climate, attic geometry, duct arrangements, and other building parameters. Homeowners, however, require simplified guidance regarding building envelope options, even those options that seem to have no simple answers. An extensive parametric evaluation of radiant barrier installation alternatives was made using a newly expanded and benchmarked version of an attic simulation program. To complement this anal- ysis, a detailed numerical analysis of radiation heat transfer within the attic and within the small space bounded by the rafters and the sheathing was completed. The results provide guidance for homeowners and builders.

Vaporization, dispersion, and radiant fluxes from LPG spills. Final technical report  

SciTech Connect

Both burning and non-burning spills of LPG (primarily propane) were studied. Vaporization rates for propane spills on soil, concrete, insulating concrete, asphalt, sod, wood, and polymer foams were measured. Thermal conductivity, heat transfer coefficients, and steady state vaporization rates were determined. Vapor concentrations were measured downwind of open propane pools and a Gaussian dispersion model modified for area sources provided a good correlation of measured concentrations. Emitted and incident radiant fluxes from propane fires were measured. Simplified flame radiation models were adequate for predicting radiant fluxes. Tests in which propane was sprayed into the air showed that at moderately high spray rates all the propane flashed to vapor or atomized; no liquid collected on the ground.

Inverse optimal design of the radiant heating in materials processing and manufacturing  

Science Conference Proceedings (OSTI)

Combined convective, conductive, and radiative heat transfer is analyzed during heating of a continuously moving load in the industrial radiant oven. A transient, quasi-three-dimensional model of heat transfer between a continuous load of parts moving inside an oven on a conveyor belt at a constant speed and an array of radiant heaters/burners placed inside the furnace enclosure is developed. The model accounts for radiative exchange between the heaters and the load, the conduction in the load, and convective heat transfer between the moving load and oven environment. The thermal model developed has been used to construct a general framework for an inverse optimal design of an industrial oven as an example. In particular, the procedure based on the Levenberg-Marquardt nonlinear least squares optimization algorithm has been developed to obtain the optimal temperatures of the heaters/burners that need to be specified to achieve a prescribed temperature distribution of the surface of a load. The results of calculations for several sample cases are reported to illustrate the capabilities of the procedure developed for the optimal inverse design of an industrial radiant oven.

Effect of Radiant Barrier Technology on Summer Attic Heat Load in South Texas  

E-Print Network (OSTI)

The objective of the study was to experimentally evaluate the performance of radiant barriers in single-family occupied housing units in South Texas. Ceiling heat fluxes, attic air temperatures, indoor air temperatures, ambient air temperatures. roof temperatures, and solar radiation were measured. Results of the radiant barrier experiment using two side-by-side 600 ft2 units are presented. Attic fiberglass insulation of nominal R-11 was installed in the two apartments when the units were last remodeled in 1974. The test houses responded similarly to weather variations, that is, attic temperature and heat flux profiles were similar in magnitude prior to the retrofit. Residents of the housing units were asked to set the thermostats at 76F. Data were analyzed for periods of time which had the greatest attic temperatures (11 a.m. - 11 p.m.) and for which the indoor temperature differences were less than 1 percent. The results showed that radiant barriers reduced ceiling heat loads (on daily basis) by an average of 60 percent.

An Evaluation of the Placement of the Placement of Radiant Barriers on their Effectiveness in Reducing Heat Transfer in Attics  

E-Print Network (OSTI)

Experimental tests were conducted to measure the influence of radiant barriers and the effect of the radiant barrier location on attic heat transfer. All the tests were conducted in an attic simulator at a steady state. The heat flux through the attic floor was measured at two different roof deck temperatures (120F and 140F). The temperature distribution within the base fibrous insulation was also measured. Three different solid kraft laminates with aluminum foil backing were tested. There was a 34 percent reduction (sample A) in heat flux through the ceiling for the case where the radiant barrier was placed 6 inches below the roof deck in addition to the base fibrous insulation (R-11), with the roof deck at 140 F. The reduction for the same sample with the radiant barrier placed on the studs of the attic floor was 46 percent. For all the three samples, the heat flux through the attic floor was reduced when the radiant barrier was placed on the attic floor studs.

A transient heat and mass transfer model of residential attics used to simulate radiant barrier retrofits. Part 2: Validation and simulations  

Science Conference Proceedings (OSTI)

A computer program was developed and used to implement the model described on Part 1 of this paper. The program used an iterative process to predict temperatures and heat fluxes using linear algebra principles. The results from the program were compared to experimental data collected during a three-year period. The model simulated different conditions such as variations in attic ventilation, variations in attic ceiling insulation, and different radiant barrier orientations for summer and winter seasons. It was observed that the model predicted with an error of less than 10% for most cases. This paper presents model results for nonradiant barrier cases as well as cases for radiant barriers installed horizontally on top of the attic floor (HRB) and for radiant barriers stapled to the attic rafters (TRB). Savings produced by radiant barriers and sensitivity analyses are also presented. The model results supported the experimental trend that emissivity was the single most significant parameter that affected the performance of radiant barriers.

Technical evaluation of a solar heating system having conventional hydronic solar collectors and a radiant panel slab. Final report  

DOE Green Energy (OSTI)

A simple innovative solar heating design (Solar Option One) using conventional hydronic solar collectors and a radiant panel slab was constructed. An objective of hybrid solar design is to combine the relative advantages of active and passive design approaches while minimizing their respective disadvantages. A test house using the Solar Option One heating system was experimentally monitored to determine its energy based performance during the 1982-83 heating season. The test residence is located in Lyndonville, Vermont, an area which has a characteristically cold and cloudy climate. The two story residence has a floor area of about 1400 square feet and is constructed on a 720 square foot 5.5 inch thick floor slab. A 24 inch packed gravel bed is located beneath the slab and the slab-gravel bed is insulated by two inches of polystyrene insulation. The test building is of frame construction and uses insulation levels which have become commonplace throughout the country. The structure would not fall into the superinsulated category but was tightly constructed so as to have a low infiltration level. The building is sun-tempered in that windows were concentrated somewhat on the South side and all but avoided on the North. A solar greenhouse on the South side of the building was closed off from the structure permanently throughout the testing so as to better observe the solar heating invention without confounding variables. The monitoring equipment generated an internal gain of about 17,000 BTUs per day, roughly the equivalent of occupancy by two persons. A full description of the experimental testing program is given. System efficiency and performance are reported.

Finite-volume model for chemical vapor infiltration incorporating radiant heat transfer. Interim report  

SciTech Connect

Most finite-volume thermal models account for the diffusion and convection of heat and may include volume heating. However, for certain simulation geometries, a large percentage of heat flux is due to thermal radiation. In this paper a finite-volume computational procedure for the simulation of heat transfer by conduction, convection and radiation in three dimensional complex enclosures is developed. The radiant heat transfer is included as a source term in each volume element which is derived by Monte Carlo ray tracing from all possible radiating and absorbing faces. The importance of radiative heat transfer is illustrated in the modeling of chemical vapor infiltration (CVI) of tubes. The temperature profile through the tube preform matches experimental measurements only when radiation is included. An alternative, empirical approach using an {open_quotes}effective{close_quotes} thermal conductivity for the gas space can match the initial temperature profile but does not match temperature changes that occur during preform densification.

Radiant Barrier Insulation Performance in Full Scale Attics with Soffit and Ridge Venting  

E-Print Network (OSTI)

There is a limited data base on the full scale performance of radiant barrier insulation in attics. The performance of RBS have been shown to be dependent on attic ventilation characteristics. Tests have been conducted on a duplex located in Florida with soffit and ridge venting to measure attic performance. The unique features of these experiments are accurate and extensive instrumentation with heat flow meters, field verification of HFM calibration, extensive characterization of the installed ceiling insulation, ventilation rate measurements and extensive temperature instrumentation. The attics are designed to facilitate experimental changes without damaging the installed insulation. RBS performance has been measured for two natural ventilation levels for soffit and ridge venting. Previously, no full scale data have been developed for these test configurations. Test data for each of the test configurations was acquired for a minimum of two weeks with some acquired over a five week period. The Rl9 insulation performed as expected.

Development of periodic response factors for use with the radiant time series method  

SciTech Connect

Harris and McQuiston (1988) developed conduction transfer function (CTF) coefficients corresponding to 41 representative wall assemblies and 42 representative roof assemblies for use with the transfer function method (TFM). They also developed a grouping procedure that allows design engineers to determine the correct representative wall or roof assembly that most closely matches a specific wall or roof assembly. The CTF coefficients and the grouping procedure have been summarized in the ASHRAE Handbook--Fundamentals (1989, 1993, 1997) and the ASHRAE Cooling and Heating Load Calculation Manual, second edition. More recently, a new, simplified design cooling load calculation procedure, the radiant time series method (RTSM), has been developed. The RTSM uses periodic response factors to model transient conductive heat transfer. While not a true manual load calculation procedure, it is quite feasible to implement the RTSM in a spreadsheet. To be useful in such an environment, it would be desirable to have a pre-calculated set of periodic response factors. Accordingly, a set of periodic response factors has been calculated and is presented in this paper.

Energy and waste reduction in the wood fiber and fuel industry utilizing a long wave length catalytic infrared drying system. Progress report Number 3  

SciTech Connect

Following the testing of the Cat-Tec handling system, detail design work commenced both at the Catalytic Industrial Systems (CIS) Kansas facility and at the Cat-Tec offices in Minneapolis for the mating of the heating and handling system elements of the catalytic infrared particulate dryer. A used equipment looped handling system designed to feed and recirculate the test material was procured and shipped to CIS in anticipation of the on-site testing. Evaluation of the findings of the test results led the joint CIS-Cat-Tec design team to conclude that the unit to be provided to Lignetics for testing needed to have approximately 120 square feet of agitation bed and approximately 100 feet of infrared generation surfaces. The overall size was thus increased approximately 50% from the initial test unit.

A transient heat and mass transfer model of residential attics used to simulate radiant barrier retrofits. Part 1: Development  

SciTech Connect

This paper describes a transient heat and mass transfer model of residential attics. The model is used to predict hourly ceiling heat gain/loss in residences with the purpose of estimating reductions in cooling and heating loads produced by radiant barriers. The model accounts for transient conduction, convection, and radiation and incorporates moisture and air transport across the attic. Environmental variables, such as solar loads on outer attic surfaces and sky temperatures, are also estimated. The model is driven by hourly weather data which include: outdoor dry bulb air temperature, horizontal solar and sky radiation, wind speed and direction, relative humidity (or dew point), and cloud cover data. The output of the model includes ceiling heat fluxes, inner and outer heat fluxes from all surfaces, inner and outer surface temperatures, and attic dry bulb air temperatures. The calculated fluxes have been compared to experimental data of side-by-side testing of attics retrofit with radiant barriers. The model predicts ceiling heat flows with an error of less than 10% for most cases.

Effect of radiant barriers and attic ventilation on residential attics and attic duct systems: New tools for measuring and modeling  

Science Conference Proceedings (OSTI)

A simple duct system was installed in an attic test module for a large scale climate simulator at a US national laboratory. The goal of the tests and subsequent modeling was to develop an accurate method of assessing duct system performance in the laboratory, enabling limiting conditions to be imposed at will and results to be applied to residential attics with attic duct systems. Steady-state tests were done at a severe summer and a mild winter condition. In all tests the roof surface was heated above ambient air temperatures by infrared lights. The attic test module first included then did not include the duct system. Attic ventilation from eave vents to a ridge vent was varied from none to values achievable by a high level of power ventilation. A radiant barrier was attached to the underside of the roof deck, both with and without the duct system in place. Tests were also done without the radiant barrier, both with and without the duct system. When installed, the insulated ducts ran along the floor of the attic, just above the attic insulation and along the edge of the attic near the eaves and one gable. These tests in a climate simulator achieved careful control and reproducibility of conditions. This elucidated dependencies that would otherwise be hidden by variations in uncontrolled variables. Based on the comparisons with the results of the tests at the mild winter condition and the severe summer condition, model predictions for attic air and insulation temperatures should be accurate within {+-} 10 F ({+-} 6 C). This is judged adequate for design purposes and could be better when exploring the effect of changes in attic and duct parameters at fixed climatic conditions.

Air-to-Water Heat Pumps With Radiant Delivery in Low-Load Homes  

SciTech Connect

Space conditioning represents nearly 50% of average residential household energy consumption, highlighting the need to identify alternative cost-effective, energy-efficient cooling and heating strategies. As homes are better built, there is an increasing need for strategies that are particularly well suited for high performance, low load homes. ARBI researchers worked with two test homes in hot-dry climates to evaluate the in-situ performance of air-to-water heat pump (AWHP) systems, an energy efficient space conditioning solution designed to cost-effectively provide comfort in homes with efficient, safe, and durable operation. Two monitoring projects of test houses in hot-dry climates were initiated in 2010 to test this system. Both systems were fully instrumented and have been monitored over one year to capture complete performance data over the cooling and heating seasons. Results are used to quantify energy savings, cost-effectiveness, and system performance using different operating modes and strategies. A calibrated TRNSYS model was developed and used to evaluate performance in various climate regions. This strategy is most effective in tight, insulated homes with high levels of thermal mass (i.e. exposed slab floors).

Long wave runup on random beaches  

E-Print Network (OSTI)

The estimation of the maximum wave sunup height is a problem of practical importance. Most of the analytical and numerical studies are limited to a constant slope plain shore and to the classical Nonlinear Shallow Water (NSW) equations. However, in nature the shore is characterized by some roughness. In order to take into account the effects of the bottom rugosity various ad-hoc friction terms are usually used. In this paper we study the effect of the roughness of the bottom on the maximum runup height. A stochastic model is proposed to describe the bottom irregularity and its effect is quantified using Monte-Carlo simulations. For the discretization of the NSW equations we employ modern finite volume schemes. Moreover, the results of the random bottom model are compared with the more conventional approaches.

Low-E Coatings Low-E Coatings Low-E Center-of-glass values of double pane units with and without low-E coatings. When heat or light energy is absorbed by glass, it is either convected away by moving air or reradiated by the glass surface. The ability of a material to radiate energy is called its emissivity. All materials, including windows, emit (or radiate) heat in the form of long-wave, far-infrared energy depending on their temperature. This emission of radiant heat is one of the important components of heat transfer for a window. Thus reducing the window's emittance can greatly improve its insulating properties. Standard clear glass has an emittance of 0.84 over the long-wave portion of the spectrum, meaning that it emits 84% of the energy possible for an object at its temperature.

Combustor design tool for a gas fired thermophotovoltaic energy converter  

DOE Green Energy (OSTI)

Recently, there has been a renewed interest in thermophotovoltaic (TPV) energy conversion. A TPV device converts radiant energy from a high temperature incandescent emitter directly into electricity by photovoltaic cells. The current Department of Energy sponsored research involves the design, construction and demonstration of a prototype TPV converter that uses a hydrocarbon fuel (such as natural gas) as the energy source. As the photovoltaic cells are designed to efficiently convert radiant energy at a prescribed wavelength, it is important that the temperature of the emitter be nearly constant over its entire surface. The US Naval Academy has been tasked with the development of a small emitter (with a high emissivity) that can be maintained at 1,756 K (2,700 F). This paper describes the computer spreadsheet model that was developed as a tool to be used for the design of the high temperature emitter.

Evaluation of the thermal resistance of a roof-mounted multi-reflective radiant barrier for tropical and humid conditions: Experimental study from field measurements  

E-Print Network (OSTI)

This paper deals with the experimental evaluation of a roof-mounted multi-reflective radiant barrier (MRRB), installed according to the state of the art, on a dedicated test cell. An existing experimental device was completed with a specific system for the regulation of the airflow rate in the upper air layer included in a typical roof from Reunion Island. Several experimental sequences were conducted to determine the thermal resistance of the roof according to several parameters and following a specific method. The mean method, well known in international standards (ISO 9869 - 1994) for the determination of the thermal resistance using dynamic data, was used. The method was implemented in a building simulation code in order to allow the determination of the thermal indicator automatically. Experimental results are proposed according to different seasonal periods and for different values of the airflow rate in the upper air layer.

Phase-change thermal energy storage: Final subcontract report  

DOE Green Energy (OSTI)

The research and development described in this document was conducted within the US Department of Energy's Solar Thermal Technology Program. The goal of this program is to advance the engineering and scientific understanding of solar thermal technology and to establish the technology base from which private industry can develop solar thermal power production options for introduction into the competitive energy market. Solar thermal technology concentrates the solar flux using tracking mirrors or lenses onto a receiver where the solar energy is absorbed as heat and converted into electricity or incorporated into products as process heat. The two primary solar thermal technologies, central receivers and distributed receivers, employ various point and line-focus optics to concentrate sunlight. Current central receiver systems use fields of heliostats (two-axes tracking mirrors) to focus the sun's radiant energy onto a single, tower-mounted receiver. Point focus concentrators up to 17 meters in diameter track the sun in two axes and use parabolic dish mirrors or Fresnel lenses to focus radiant energy onto a receiver. Troughs and bowls are line-focus tracking reflectors that concentrate sunlight onto receiver tubes along their focal lines. Concentrating collector modules can be used alone or in a multimodule system. The concentrated radiant energy absorbed by the solar thermal receiver is transported to the conversion process by a circulating working fluid. Receiver temperatures range from 100{degree}C in low-temperature troughs to over 1500{degree}C in dish and central receiver systems. 12 refs., 119 figs., 4 tabs.

LED Surgical Task Lighting Scoping Study: A Hospital Energy Alliance Project  

SciTech Connect

Tungsten-halogen (halogen) lamps have traditionally been used to light surgical tasks in hospitals, even though they are in many respects ill-suited to the application due to the large percentage of radiant energy outside the visible spectrum and issues with color rendering/quality. Light-emitting diode (LED) technology offers potential for adjustable color and improved color rendition/quality, while simultaneously reducing side-effects from non-visible radiant energy. It also has the potential for significant energy savings, although this is a fairly narrow application in the larger commercial building energy use sector. Based on analysis of available products and Hospital Energy Alliance member interest, it is recommended that a product specification and field measurement procedure be developed for implementation in demonstration projects.

Thermophotovoltaic energy conversion using photonic bandgap selective emitters  

DOE Patents (OSTI)

A method for thermophotovoltaic generation of electricity comprises heating a metallic photonic crystal to provide selective emission of radiation that is matched to the peak spectral response of a photovoltaic cell that converts the radiation to electricity. The use of a refractory metal, such as tungsten, for the photonic crystal enables high temperature operation for high radiant flux and high dielectric contrast for a full 3D photonic bandgap, preferable for efficient thermophotovoltaic energy conversion.

Air-To-Water Heat Pumps with Radiant Delivery in Low Load Homes: Tucson, Arizona and Chico, California (Fact Sheet)  

SciTech Connect

Space conditioning represents nearly 50% of average residential household energy consumption, highlighting the need to identify alternative cost-effective, energy-efficient cooling and heating strategies. As homes are better built, there is an increasing need for strategies that are particularly well suited for high performance, low load homes. ARBI researchers worked with two test homes in hot-dry climates to evaluate the in-situ performance of air-to-water heat pump (AWHP) systems, an energy efficient space conditioning solution designed to cost-effectively provide comfort in homes with efficient, safe, and durable operation. Two monitoring projects of test houses in hot-dry climates were initiated in 2010 to test this system. Both systems were fully instrumented and have been monitored over one year to capture complete performance data over the cooling and heating seasons. Results are used to quantify energy savings, cost-effectiveness, and system performance using different operating modes and strategies. A calibrated TRNSYS model was developed and used to evaluate performance in various climate regions. This strategy is most effective in tight, insulated homes with high levels of thermal mass (i.e. exposed slab floors).

Greenhouse gases are those gases-such as water vapor, carbon dioxide (CO 2 ), methane, nitrous oxide, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride-that are transparent to solar (short- wave) radiation but opaque to long-wave (infrared) radiation, thus preventing long-wave radiant energy from leaving Earth's atmosphere. The net effect is a trapping of absorbed radiation and a tendency to warm the planet's surface. Energy-related carbon dioxide emissions account for about 98 percent of U.S. CO 2 emissions. The vast majority of CO 2 emissions come from fossil fuel combustion, with smaller amounts from the nonfuel use of fossil fuels, as well as from electricity generation using geothermal energy and non-

Thermodynamic Analysis for Energy Conservation  

E-Print Network (OSTI)

This paper describes a methodology for performing a thermodynamic analysis of a process, and it demonstrates how such a study can be useful in identifying areas in the process with the greatest potential for improvement in energy use. The basis is a typical modern ethane cracker. The processing sequence was divided into subsections and the 'lost work' of each section quantified. Combustion and radiant heat transfer in the furnaces and boilers alone result in the loss of 50% of the availability that enters the plant. Based on these data, some suggestions for significant process improvement are analyzed. For situations where entropy calculations are impractical, a generalized check list is presented which identifies areas of potential economic impact for the process developer/designer, as a partial substitute for the full analysis.

Should such fluid not be present within the device for any reason, e.g. upon pump failure, sunlight entering in positively directed outwardly thereof. Preferably the outward direction of sunlight from the fluid receiving chamber is accomplished by providing one of the surfaces forming such chamber with a highly reflective surface so that the sun's rays are outwardly deflected. In certain embodiments, as when the device is used as an architectural window, when such fluid is not present within the device, the solar energy is directed entirely through the device. In this manner, the chamber temperature may be held within tolerable levels for the particular plastics utilized.

Energy collector for collecting solar energy and the like  

SciTech Connect

A solar energy collector connectable with a fluid-circulating system is contained in a plenum within an insulative housing and has a plurality of generally parallel, heat-absorbing conduits extending between intake and outlet manifolds and confronting the sun or other heat source through a transparent window, each conduit being separated from an adjacent conduit by an intervening slot. Positioned below the conduits is a heat-absorbing tank which is connected in fluid-flow relationship with the outlet manifold and also with the circulation system so that a heat-transfer medium may flow continuously between the energy collector and the circulation system. The tank receives radiant energy through the slots and after absorbing some of the radiation reflects the remaining portion upwardly to the conduits to thereby increase radiation intensity on and heat absorption by the conduits. Multiple reflections between tank and conduits further increase energy absorption both by tank and conduit. The conduits may be of round cross section or may have a planar heat-absorbing surface facing the sun and an arcuate, convex surface facing the tank. The tank may be provided with a plurality of arcuate troughs, a trough underlying and paralleling each conduit to both absorb energy and reflect energy toward the overlying conduit. The conduits may be provided with internal air ducts which communicate with the hot-air plenum and permit heat from the hot air to be transferred through the duct walls and to the fluid medium within the conduits.

BigHorn Home Improvement Center Energy Performance  

Science Conference Proceedings (OSTI)

The BigHorn Development Project, located in Silverthorne, Colorado, is one of the nation's first commercial building projects to integrate extensive high-performance design into a retail space. The BigHorn Home Improvement Center, completed in the spring of 2000, is a 42,366-ft2 (3,936 m2) hardware store, warehouse, and lumberyard. The authors were brought in at the design stage of the project to provide research-level guidance to apply an integrated design process and perform a postoccupancy evaluation. An aggressive energy design goal of 60% energy cost saving was set early in the process, which focused the efforts of the design team and provided a goal for measuring the success of the project. The extensive use of natural light, combined with energy-efficient electrical lighting design, provides good illumination and excellent energy savings. The reduced lighting loads, management of solar gains, and cool climate allow natural ventilation to meet the cooling loads. A hydronic radiant floor system, gas-fired radiant heaters, and a transpired solar collector deliver heat. An 8.9-kW roof-integrated photovoltaic (PV) system offsets a portion of the electricity. After construction, the authors installed monitoring equipment to collect energy performance data and analyzed the building's energy performance for two and one-half years. The authors also helped program the building controls and provided recommendations for improving operating efficiency. The building shows an estimated 53% energy cost saving and a 54% source energy saving. These savings were determined with whole-building energy simulations that were calibrated with measured data. This paper discusses lessons learned related to the design process, the daylighting performance, the PV system, and the heating, ventilating, and air-conditioning system.

Use of compound parabolic concentrator for solar energy collection  

DOE Green Energy (OSTI)

The joint team of Argonne National Laboratory (ANL) and the University of Chicago is reporting their midyear results of a proof-of-concept investigation of the Compound Parabolic Concentrator (CPC) for solar-energy collection. The CPC is a non-imaging, optical-design concept for maximally concentrating radiant energy onto a receiver. This maximum concentration corresponds to a relative aperture (f/number) of 0.5, which is well beyond the limit for imaging collectors. We have constructed an X3 concentrating flat-plate collector 16 ft/sup 2/ in area. This collector has been tested in a trailer laboratory facility built at ANL. The optical and thermal performance of this collector was in good agreement with theory. We have constructed an X10 collector (8 ft/sup 2/) and started testing. A detailed theoretical study of the optical and thermal characteristics of the CPC design has been performed.

The integrated control system is a low cost solution and also features: Scalable component based architecture allows to build a solution for different building control system configurations with needed components; Open Architecture with a central data repository for data exchange among runtime components; Extendible to accommodate variety of communication protocols. Optimal building control for central loads, distributed loads and onsite energy resource Uses web server as a loosely coupled way to engage both building operators and building occupants in collaboration for energy conservation. Based on the open platform of SEB, we have investigated and evaluated a variety of operation and energy saving control strategies on Carnegie Mellon University Intelligent Work place which is equipped with alternative cooling/heating/ventilation/lighting methods, including radiant mullions, radiant cooling/heating ceiling panels, cool waves, dedicated ventilation unit, motorized window and blinds, and external louvers. Based on the validation results of these control strategies, they were integrated in SEB in a collaborative and dynamic way. This advanced control system was programmed and computer tested with a model of the Intelligent Workplace??s northern section (IWn). The advanced control program was then installed in the IWn control system; the performance were measured and compared with that of the state of the art control system to verify the overall energy savings great than 40%. In addition advanced human machine interfaces (HMI's) were developed to communicate both with building occupants and the building operator. Lifecycle cost analyses of the advanced building control were performed, and a Building Control System Guide was prepared and published to inform owners, architects, and engineers dealing with new construction or renovation of buildings.

Main Street Net-Zero Energy Buildings: The Zero Energy Method in Concept and Practice  

SciTech Connect

Until recently, large-scale, cost-effective net-zero energy buildings (NZEBs) were thought to lie decades in the future. However, ongoing work at the National Renewable Energy Laboratory (NREL) indicates that NZEB status is both achievable and repeatable today. This paper presents a definition framework for classifying NZEBs and a real-life example that demonstrates how a large-scale office building can cost-effectively achieve net-zero energy. The vision of NZEBs is compelling. In theory, these highly energy-efficient buildings will produce, during a typical year, enough renewable energy to offset the energy they consume from the grid. The NREL NZEB definition framework classifies NZEBs according to the criteria being used to judge net-zero status and the way renewable energy is supplied to achieve that status. We use the new U.S. Department of Energy/NREL 220,000-ft{sub 2} Research Support Facilities (RSF) building to illustrate why a clear picture of NZEB definitions is important and how the framework provides a methodology for creating a cost-effective NZEB. The RSF, scheduled to open in June 2010, includes contractual commitments to deliver a Leadership in Energy Efficiency and Design (LEED) Platinum Rating, an energy use intensity of 25 kBtu/ft{sub 2} (half that of a typical LEED Platinum office building), and net-zero energy status. We will discuss the analysis method and cost tradeoffs that were performed throughout the design and build phases to meet these commitments and maintain construction costs at $259/ft{sub 2}. We will discuss ways to achieve large-scale, replicable NZEB performance. Many passive and renewable energy strategies are utilized, including full daylighting, high-performance lighting, natural ventilation through operable windows, thermal mass, transpired solar collectors, radiant heating and cooling, and workstation configurations allow for maximum daylighting.

Energy Technologies for the 21st Century-The Roles of Renewable Energy  

DOE Green Energy (OSTI)

Renewable energy sources, originating for the most part from the sun's radiant energy, are ubiquitous, long-lived, essentially free of carbon emissions, and have the potential to contribute significantly to mounting energy needs of the globe. In terms of percentage increase in installed capacity, renewable energy collectively is the fastest growing energy source. Even assuming that the developing world raises its standard of living considerably, the technical potential of renewable energies is more than enough to meet annual global needs several times over a century from now. Realizing even some of this potential involves overcoming obstacles in generation costs, proximity to markets, and in many cases intermittency, as well as others. From the perspective of work on a wide range of energy technologies by both the World Energy Council and the Intergovernmental Panel on Climate Change, the potential, timing, and investment costs for renewable energy technologies in the 21st century have become clearer. The marketplace, based on cost and performance, will determine which technologies are commercialized along with government policies that at a minimum do not hinder their introduction, and--at a maximum--may encourage more rapid and successful introduction. A wide range of possible scenarios (34) based on factors that include energy availability, demographics, economic development, competition, environmental constraints, and most importantly technical learning, place some constraints on the range of possible energy requirements. Most scenarios indicate that renewable energy in total is likely to be as much as half the world's supply in 100 years, but most of that growth is expected in the period 50 to 100 years from now--if critical advancements and investments are made over the next 50 years.

Design considerations for a thermophotovoltaic energy converter using heat pipe radiators  

DOE Green Energy (OSTI)

The purpose of this paper is to discuss concepts for using high temperature heat pipes to transport energy from a heat source to a thermophotovoltaic (TPV) converter. Within the converter, the condenser portion of each heat pipe acts as a photon radiator, providing a radiant flux to adjacent TPV cells, which in turn create electricity. Using heat pipes in this way could help to increase the power output and the power density of TPV systems. TPV systems with radiator temperatures in the range of 1,500 K are expected to produce as much as 3.6 W/cm{sup 3} of heat exchanger volume at an efficiency of 20% or greater. Four different arrangements of heat pipe-TPV energy converters are considered. Performance and sizing calculations for each of the concepts are presented. Finally, concerns with this concept and issues which remain to be considered are discussed.

Current Issues in Terrestrial Solar Radiation Instrumentation for Energy, Climate and Space Applications Preprint prepared for New RAD '99  

DOE Green Energy (OSTI)

Reductions of uncertainty in terrestrial solar radiation measurements are needed to validate the Earth's radiation balance derived from satellite data. Characterization of solar energy resources for renewable technologies requires greater time and spatial resolution for economical technology deployment. Solar radiation measurement research at the National Renewable Energy Laboratory addresses calibrations, operational characteristics, and corrections for terrestrial solar radiation measurements. We describe progress in measurements of broadband diffuse-sky radiation, and characterization of field instrument thermal offsets and spectral irradiance. The need and prospects for absolute references for diffuse and long-wave terrestrial solar radiation measurements are discussed. Reductions in uncertainty of broadband irradiance measurements from tens of watts per square meter to a few (one to two) watts per square meter are reported, which reduce time and labor to quantify and identify trends in artificial optical radiation sources, terrestrial solar radiation, and the Earth's radiation budget.

Photonic Crystals for Enhancing Thermophotovoltaic Energy Conversion  

DOE Green Energy (OSTI)

Thermophotovoltaics (TPV) converts the radiant energy of a thermal source into electrical energy using photovoltaic cells. TPV has a number of attractive features, including: fuel versatility (nuclear, fossil, solar, etc.), quiet operation, low maintenance, low emissions, light weight, high power density, modularity, and possibility for cogeneration of heat and electricity. Some of these features are highly attractive for military applications (Navy and Army). TPV could also be used for distributed power and automotive applications wherever fuel cells, microturbines, or cogeneration are presently being considered if the efficiencies could be raised to around 30%. This proposal primarily examine approaches to improving the radiative efficiency. The ideal irradiance for the PV cell is monochromatic illumination at the bandgap. The photonic crystal approach allows for the tailoring of thermal emission spectral bandwidth at specific wavelengths of interest. The experimental realization of metallic photonic crystal structures, the optical transmission, reflection and absorption characterization of it have all been carried out in detail and will be presented next. Additionally, comprehensive models of TPV conversion has been developed and applied to the metallic photonic crystal system.

Integration of Low Energy Technologies for Optimal Building and Space Conditioning Design  

DOE Green Energy (OSTI)

EnergyPlus is the DOE's newest building energy simulation engine. It was developed specifically to support the design of low energy building systems. This project focused on developing new low energy building simulation models for EnergyPlus, verifying and validating new and existing EnergyPlus models and transferring the new technology to the private sector. The project focused primarily on geothermal and radiant technologies, which are related by the fact that both are based on hydronic system design. As a result of this project eight peer reviewed journal and conference papers were added to the archival literature and five technical reports were published as M.S. theses and are available in the archival literature. In addition, several reports, including a trombe wall validation report were written for web publication. Thirteen new or significantly enhanced modules were added to the EnergyPlus source code and forty-two new or significantly enhanced sections were added to the EnergyPlus documentation as a result of this work. A low energy design guide was also developed as a pedagogical tool and is available for web publication. Finally several tools including a hybrid ground source heat pump optimization program and a geothermal heat pump parameter estimation tool were developed for research and design and are available for web publication.

Product and Process Modeling for Functional Performance Testing in Low-Energy Building Embedded Commissioning Cases  

E-Print Network (OSTI)

Our work deals with creating information assistance for commissioning (Cx) low-energy buildings throughout their life-cycle. We call this Embedded Commissioning in reference to the integration of persistent and reliable Cx information. We have developed digital models of the Cx process and products. Currently, we are testing system inspection and functional performance test (FPT) protocols developed by others to verify their applicability to individual facilities and compatibility with our product models, as well as standards, such as IFC and aecXML. To date we have tested a fin-tube radiant heat system FPT. Our findings include lessons learned in several areas: (1) adapting standard FPTs to specific facilities and their design intent, (2) common performance retarding system defects, and (3) implications for data representation in product/process models for FPT implementation.

Design and Construct a New Energy-Efficient Commercial Building Design and Construct a New Energy-Efficient Commercial Building Photo of NREL's Research Support Facility under construction, with two workers straddling I-beams. The National Renewable Energy Laboratory's Research Support Facility in an early stage of construction. Establishing and implementing aggressive energy performance goals during the design and construction of new commercial buildings is important to achieving those goals over the lifetime of the building. Energy efficiency measures can be applied in various stages of the design and construction process, including scoping and design, procurement, codes and standards compliance, construction and commissioning. Energy savings through these measures can be significant and will have lasting positive impacts on the overall energy use of the building. For example, using technologies and concepts such as radiant heating and cooling, precast concrete insulated panels, and an on-site solar energy system, NREL's Research Support Facility (RSF) is 50 percent more efficient than ASHRAE 90.1 2004 Standards.

Advanced Building Efficiency Testbed Initiative/Intelligent Workplace Energy Supply System; ABETI/IWESS  

DOE Green Energy (OSTI)

ABETI/IWESS is a project carried out by Carnegie Mellon's Center for Building Performance and Diagnostics, the CBPD, supported by the U.S. Department of Energy/EERE, to design, procure, install, operate, and evaluate an energy supply system, an ESS, that will provide power, cooling, heating and ventilation for CBPD's Intelligent Workplace, the IW. The energy sources for this system, the IWESS, are solar radiation and bioDiesel fuel. The components of this overall system are: (1) a solar driven cooling and heating system for the IW comprising solar receivers, an absorption chiller, heat recovery exchanger, and circulation pump; (2) a bioDiesel fueled engine generator with heat recovery exchangers, one on the exhaust to provide steam and the other on the engine coolant to provide heated water; (3) a ventilation system including an enthalpy recovery wheel, an air based heat pump, an active desiccant wheel, and an air circulation fan; and (4) various convective and radiant cooling/heating units and ventilation air diffusers distributed throughout the IW. The goal of the ABETI/IWESS project is to demonstrate an energy supply system for a building space that will provide a healthy, comfortable environment for the occupants and that will reduce the quantity of energy consumed in the operation of a building space by a factor of 2 less than that of a conventional energy supply for power, cooling, heating, and ventilation based on utility power and natural gas fuel for heating.

Building for the Pacific Rim Countries. Energy-efficient building strategies for hot, humid climates  

DOE Green Energy (OSTI)

This book has been published by the Solar Energy Industries Association (SEIA), the US trade association of the solar thermal, photovoltaic, and passive solar manufacturers, distributors, and component suppliers. Its purpose is to help architects, builders, and developers construct energy-efficient homes in hot humid climates like the Pacific Rim Countries, and to allow occupants of these homes to enjoy enhanced comfort without reliance on mechanical air-conditioning systems. Two important factors are addressed in this book. First, the past few years have seen a tremendous increase in practical applications of new research. The current popularity of ceiling paddle fans, attic radiant barriers and natural daylighting attest to the importance of keeping up with the latest concepts in energy-reduction and comfort-awareness. Professionals who have been in the field for the past few years may be unaware of the latest research findings--some of which dramatically alter prior thinking on such subjects as natural ventilation or mechanical air conditioning. The second factor is the importance of site-specific characteristics, which greatly affect building strategies and designs. A thorough understanding of the climate is a prerequisite to good building design. Such factors as temperature, humidity, wind speed and direction, and solar radiation must be understood and properly integrated into the design for the home to be truly energy-efficient.

Thermal Energy Storage Evaluation Program: 1986 annual report. [Economic planning, technical assessment, field tests  

DOE Green Energy (OSTI)

The Thermal Energy Storage Evaluation Program activities were initiated to provide economic planning, technical assessment and field testing support for the thermal energy storage program, as well as management of the overall program for the DOE. Economic planning included two assessment studies. In technical assessment, issues that might affect an assessment were outlined for the development of a standard methodology to conduct assessments; work is underway to establish ''market-based'' cost and performance goals for cool storage technologies in residential applications; planning has begun for investigation of benefits in incorporating aquifer thermal energy storage with heat pumps; and plans are being formulated to evaluate the potential benefit of using aquifer thermal energy storage to augment power plant cooling. Field testing to develop technologies for the recovery and reuse of industrial waste heat began with the instrumentation design for the ceramic/salt matrix in an operating brick-making plant. Work in advanced studies by Lawrence Berkeley Laboratory continued on thermochemical conversion and storage using small particles as the heat exchanger catalyst. In SO/sub 3/ dissociation experiments at 645/sup 0/C using light and dark conditions, results clearly demonstrated the benefit in directly radiantly heating the catalyst to accomplish the endothermic step of a thermochemical storage reaction.

Pacific Northwest Laboratory annual report for 1989 to the DOE (Department of Energy) Office of Energy Research - Part 3: Atmospheric Sciences  

Science Conference Proceedings (OSTI)

This 1989 Annual Report from Pacific Northwest Laboratory (PNL) to the US Department of Energy (DOE) describes research in environment, safety, and health conducted during fiscal year 1989. The report again consists of five parts, each in a separate volume. This volume contains research in the atmospheric sciences. Currently, the broad goals of atmospheric research at PNL are to describe and predict the nature and fate of atmospheric contaminants and to develop an understanding of the atmospheric processes contributing to their distribution on local, regional, continental, and global scales in the air, in clouds, and on the surface. The redistribution and long-range transport of transformed contaminants passing through clouds is recognized as a necessary extension of our research to even larger scales in the future. Eventually, large-scale experiments on cloud processing and redistribution of contaminants will be integrated into the national program on global change, investigating how energy pollutants affect aerosols and clouds and the transfer of radiant energy through them. As the significance of this effect becomes clear, its global impact on climate will be studied through experimental and modeling research. The description of ongoing atmospheric research at PNL is organized in terms of the following study areas: atmospheric studies in complex terrain, large-scale atmospheric transport and processing of emissions, and climate change. This report describes the progress in FY 1989 in each of these areas. A divider page summarizes the goals of each area and lists project titles that support research activities. 9 refs., 2 figs., 3 tabs.

Doorway States and the Super-Radiant Mechanism  

Science Conference Proceedings (OSTI)

A new approach to physics of doorway states in nuclear reactions is developed. It is argued that the coupling of intrinsic states to the continuum through special doorway state(s) may create the situation similar to the optical super-radiance, when the segregation of broad (short-lived) resonances and trapped (long-lived) states occurs. Necessary conditions are discussed, along with applications to isobaric analog states, single-particle resonances, giant resonances, and fission through a double-humped barrier. This pattern can be observed in other mesoscopic systems as well.

Effects of low-emissivity glazings on energy use patterns in nonresidential daylighted buildings  

SciTech Connect

Fenestration is the most significant envelope design determinant of energy use in nonresidential buildings. This paper presents our assessment of energy use effects of low-emissivity (low-E) versus conventional glazings for a range of window-to-wall ratios in a daylighted office building, in representative hot and cold climates. Low-E glazings transmit ''cooler'' daylight than their conventional counterparts because, for a given visible transmittance, they reflect a much larger fraction of incident solar infrared radiation. We thus use the ratio of visible transmittance to shading coefficient, which we define as K/sub e/, to compare the effect of representative glazing characteristics on component and total-building energy use, peak electrical demand, and required cooling equipment sizes. It is concluded that insulated glazings with low-E coatings can provide lighting and cooling energy savings in both hot and cold climates. The most dramatic lighting, cooling, and total electricity energy savings are achieved for increases of K/sub e/ within the range of 0.5 to 1.0; higher K/sub e/s provide diminishing savings. The increased R-value of low-E insulated glass units provides significant benefits in cold climates and is not a liability in hot climates. Low-E glazings also help increase the mean radiant temperature of interior environments in winter and reduce it in summer, and provide greater architectural design freedom without adverse energy consequences. Further, the higher first costs of these glazings may be more than offset by savings from smaller cooling equipment, energy and peak-demand cost savings, long-term financial gains from better rentals, and increased productivity due to improved occupant comfort.

Monitoring and Optimization of Building Operations of a Low-Energy School Building  

E-Print Network (OSTI)

The ambitious design and energy concept of the new Gebhard-Mller-Schule (GMS) school building in Biberach/Riss, Germany proved itself during the first three school years of operation. The intended target value of 30 kWh/(m2a) overall heating energy consumption was almost met during the second year of operation in 2006 and finally achieved in 2007, due to well-working optimization measures, which were identified through monitoring of the building operation. Heating and cooling energy is mainly provided by a groundwater well plant, which serves as a heat source for two heat pumps as well as a direct cooling source for supplying the radiant heating and cooling system that is integrated in the concrete floor and ceiling slabs (thermally activated building component systems TABS). Indoor air conditioning and server room cooling are also connected to the groundwater cooling system. The main component of the groundwater well plant is a submersible pump on the bottom of the well which is located underneath the building. The pump supplies the building reliably with geothermal energy, but also consumes a significant amount of electricity. Monitoring and optimization of the buildings operation, funded by the Federal Ministry of Economics and Technology in Germany, revealed fundamental findings about the operation of the system and the possibilities to improve the buildings performance. Since 2005, the measurements show a continuous increase in efficiency, particularly in the field of auxiliary energies. This significantly increased performance clearly shows the potential of the use of groundwater for heating and cooling purposes and of thermally activated building component systems. In addition the measurements reveal the sensitivity of the system efficiency in terms of operating parameters.

The NASA program is directed at establishing the technical feasibility of an advanced, light-weight, long-life thermionic conversion system compatible with a remote nuclear or solar heat source. The principal application foreseen at this time is in nuclear electric propulsion (NEP) missions in the mid-1990's. Significant accomplishments for the DOE program include: (1) successfully operating a thermionic converter using a cold insulator seal (Plexiglass and Viton); (2) completed fabrication and testing of SPC-9, a reference planar converter with smooth molybdenum electrodes; (3) created a shooting type analytical ignited mode converter computer model; (4) projected the operating conditions needed to achieve advanced converter performance with a thick cesium oxide collector; and (5) invented a cellular ceramic heat exchanger for obtaining high radiant heat flux from a hot gas. Accomplishments for the NASA program include: (1) achieved over 3100 hours of operation with the cylindrical converter JPL-5 (STR/STR); (2) provided guidelines for definition of optimum lead characteristics in the JPL NEP computer program; and (3) performed a preliminary NEP optimization study which suggests a 400 kWe system with a specific mass of 26 kg/kWe is possible with present converter performance (V/sub B/ = 2.0). Details are presented. (WHK)

They include fossil and renewable energy technologies (e.g., photovoltaic arrays, wind turbines, microturbines, reciprocating engines, fuel cells, combustion turbines, and steam turbines); energy storage devices (e.g., batteries and flywheels); and combined heat and power systems. Distributed energy offers solutions to many of the nation's most pressing energy and electric power problems, including blackouts and brownouts, energy security concerns, power quality issues, tighter emissions standards, transmission bottlenecks, and the desire for greater control over energy costs.

Gravitational energy  

E-Print Network (OSTI)

Observers at rest in a stationary spacetime flat at infinity can measure small amounts of rest-mass+internal energies+kinetic energies+pressure energy in a small volume of fluid attached to a local inertial frame. The sum of these small amounts is the total "matter energy" for those observers. The total mass-energy minus the matter energy is the binding gravitational energy. Misner, Thorne and Wheeler evaluated the gravitational energy of a spherically symmetric static spacetime. Here we show how to calculate gravitational energy in any static and stationary spacetime for isolated sources with a set of observers at rest. The result of MTW is recovered and we find that electromagnetic and gravitational 3-covariant energy densities in conformastatic spacetimes are of opposite signs. Various examples suggest that gravitational energy is negative in spacetimes with special symmetries or when the energy-momentum tensor satisfies usual energy conditions.

Energy Conservation Design Features of the ARCO Metals Logan County Aluminum Process Complex  

E-Print Network (OSTI)

ARCO Metals Company (Formerly Anaconda Aluminum Company) is proceeding as scheduled with the construction of a $400 Million aluminum processing complex in Logan County, Kentucky. When the initial construction phase is completed in the Fall 1983, the complex will be capable of producing 400 million pounds per year of aluminum, sheet and foil using highly automated, computer controlled equipment that will maximize end product quality and minimize the consumption of energy. This paper will describe the basic processes used in the Logan complex and several design features that are being incorporated to reduce energy consumption. Large reverberatroy melting furnaces will remelt scrap aluminum and ingots will be cast on site to supplement those delivered to the site from ARCO Metal's reduction plants. The melting furnaces are expected to achieve a high efficiency which will be further enhanced by the utilization of exhaust gases to preheat the scrap as well as the combustion air. A coreless induction furnace will be used to reduce the melt loss normally associated with light gauge scrap. The ingots will be heated prior to rolling in the hot mill in direct fired preheating furnaces with variable speed fans that minimize cycle time. Flue gasses from these furnaces will be used to generate steam In a waste heat boiler. Motor loads in the hot mill and cold mills, along with other electrical loads, will be monitored by a computer system to minimize peak loading on the TVA power system. Annealing of aluminum coils will be accomplished in radiant tube furnaces with variable speed fan drives in an inert atmosphere produced by an electric powered air separation plant. These furnaces will use recuperative burners. The HVAC system incorporates a feature that will recover stratified hot air for use in other parts of the complex for ambient temperature control.

Energy Conservation vs. Energy Efficiency  

Science Conference Proceedings (OSTI)

Energy conservation is considered by some as synonymous with energy efficiency, but to others, it has a meaning of getting fewer or lower quality energy services. The degree of confusion between these meanings varies widely by individual, culture, historic period and language spoken. In the context of this document, energy conservation means to keep from being lost or wasted; saved, and energy efficiency means the ability to produce a desired effect or product with a minimum of effort, expense or waste.

Energy Science Energy Science Energy Science Print Our current fossil-fuel-based system is causing potentially catastrophic changes to our planet. The quest for renewable, nonpolluting sources of energy requires us to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels. Light-source facilities-the synchrotrons of today and the next-generation light sources of tomorrow-are the scientific tools of choice for exploring the electronic and atomic structure of matter. As such these photon-science facilities are uniquely positioned to jump-start a global revolution in renewable and carbon-neutral energy technologies. To establish the scientific foundations for the kind of transformative breakthroughs needed to build a 21st-century energy economy, we must address fundamental questions involving matter and energy. Below is a sampling of such questions that can be addressed by light-source facilities:

Hubble Energy  

E-Print Network (OSTI)

Light received from a cosmological source is redshifted with an apparent loss of energy, a problem first pointed out by Edwin Hubble in 1936. A new type of energy called Hubble Energy is introduced to restore the principle of energy conservation. The energy has no inertial or gravitational effect but retards radial motion in a manner consistent with the anomalous acceleration experienced by the Pioneer probes leaving the solar system. The energy is predicted to have important effects on the scale of galaxies, and some of these effects are qualitatively examined: for example, with Hubble Energy, flat rotation curves are found to be an inevitable consequence of spiral galaxy formation. The Hubble Energy is incorporated into the Friedmann Equation and shown to add a term similar to the cosmological term, with a magnitude of order 10^-35 s^-2.
