Thermal insulated glazing unit  

SciTech Connect

An improved insulated glazing unit is provided which can attain about R5 to about R10 thermal performance at the center of the glass while having dimensions about the same as those of a conventional double glazed insulated glazing unit. An outer glazing and inner glazing are sealed to a spacer to form a gas impermeable space. One or more rigid, non-structural glazings are attached to the inside of the spacer to divide the space between the inner and outer glazings to provide insulating gaps between glazings of from about 0.20 inches to about 0.40 inches. One or more glazing surfaces facing each thermal gap are coated with a low emissivity coating. Finally, the thermal gaps are filled with a low conductance gas such as krypton gas.

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

Vacuum Glazing; A Thermally Insulating Window Technology Vacuum Glazing; A Thermally Insulating Window Technology Speaker(s): Cenk Kocer Date: May 31, 2012 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Sunnie Lim The vacuum glazing consists of two panes of glass separated by a sub-millimetre vacuum gap. Under the action of atmospheric pressure the separation of the panes is maintained by an array of high strength spacers in the gap. The glass panes are hermetically sealed at the edge using a low melting point glass frit (solder glass). Since 1913 many have worked on a practical implementation of such a flat insulating glass structure, with success finally being reported in 1989 by Collins et al. at the University of Sydney. The purpose of this talk is to present a brief history of the vacuum glazing research at the University of Sydney, and outline in detail

Highly Insulating Glazing Systems using Non-Structural Center Glazing Layers  

SciTech Connect

Three layer insulating glass units with two low-e coatings and an effective gas fill are known to be highly insulating, with center-of-glass U-factors as low as 0.57 W/m{sup 2}-K (0.10 Btu/h-ft{sup 2}- F). Such units have historically been built with center layers of glass or plastic which extend all the way through the spacer system. This paper shows that triple glazing systems with non-structural center layers which do not create a hermetic seal at the edge have the potential to be as thermally efficient as standard designs, while potentially removing some of the production and product integration issues that have discouraged the use of triples.

Performance criteria for center layer of triple glazing  

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

Performance criteria for center layer of triple glazing Performance criteria for center layer of triple glazing Traditional highly insulating windows are made of three pieces of glass. Alternatively, the center layer can be a thin layer of coated plastic. (See Figure 1). In both cases, the center layer is sealed between two spacers, creating two completely separate spaces, and extending through the edge of the insulating glass unit. Recent research has shown that a simple "convection" barrier, as shown in Figure 2, which does not extend through the edge of the insulating glass unit, is as effective an insulator as traditional designs. Advantages include a simpler and more reliable edge design and potentially reduced manufacturing costs. We have investigated various plastics and edge constraint designs and are now focused on the use of an acrylic layer, between 1mm and 3mm thick. Bent edges will help keep the layer in place (see Figure 3a,b,c). In order to commercialize such a product, several issues remain to be addressed. These issues, as they relate to acrylic, are defined below. Other plastics and designs can still be explored.

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.

Energy performance of evacuated glazings in residential buildings  

SciTech Connect

This paper presents the results of a study investigating the energy performance of evacuated glazings or glazings which maintain a vacuum between two panes of glass. Their performance is determined by comparing results to prototype highly insulated superwindows as well as a more conventional. insulating glass unit with a low-E coating and argon gas fill. We used the DOE2.1E energy analysis simulation program to analyze the annual and hourly heating energy use due to the windows of a prototypical single-story house located in Madison, Wisconsin. Cooling energy performance was also investigated. Our results show that for highly insulating windows, the solar heat gain coefficient is as important as the window`s U-factor in determining heating performance for window orientations facing west-south-east. For other orientations in which there is not much direct solar radiation, the window`s U-factor primarily governs performance. The vacuum glazings had lower heating requirements than the superwindows for most window orientations. The conventional low-E window outperformed the superwindows for southwest-south-southeast orientations These performance differences are directly related to the solar heat gain coefficients of the various windows analyzed. The cooling performance of the windows was inversely related to the heating performance. The lower solar heat gain coefficients of the superwindows resulted in the best cooling performance. However, we were able to mitigate the cooling differences of the windows by using an interior shading device that reduced the amount of solar gain at appropriate times.

Spectrally selective glazings  

SciTech Connect

Spectrally selective glazing is window glass that permits some portions of the solar spectrum to enter a building while blocking others. This high-performance glazing admits as much daylight as possible while preventing transmission of as much solar heat as possible. By controlling solar heat gains in summer, preventing loss of interior heat in winter, and allowing occupants to reduce electric lighting use by making maximum use of daylight, spectrally selective glazing significantly reduces building energy consumption and peak demand. Because new spectrally selective glazings can have a virtually clear appearance, they admit more daylight and permit much brighter, more open views to the outside while still providing the solar control of the dark, reflective energy-efficient glass of the past. This Federal Technology Alert provides detailed information and procedures for Federal energy managers to consider spectrally selective glazings. The principle of spectrally selective glazings is explained. Benefits related to energy efficiency and other architectural criteria are delineated. Guidelines are provided for appropriate application of spectrally selective glazing, and step-by-step instructions are given for estimating energy savings. Case studies are also presented to illustrate actual costs and energy savings. Current manufacturers, technology users, and references for further reading are included for users who have questions not fully addressed here.

Thermal performance assessment of an advanced glazing system  

SciTech Connect

The four different techniques which were used to test an advanced, four-pane glazing system and standard double-glazed unit are described. The results from each test are compared. Where agreement is not good, explanations are suggested. The advanced glazing system was found to have a U-value of 0.9 W/m[sup 2] K and a shading coefficient of 0.48. The glazing simulation models WINDOW (Lawrence Berkeley Laboratories, Berkeley, CA, US) and MULTB (Pilkington Glass, U.K.) were used to predict glazing performance. Simulation of the two glazing systems which were experimentally assessed allows comparison between models, and between predicted and measured performance. Agreement was within the error bands associated with each assessment. 7 refs., 2 figs., 1 tab.

Electrochromic Glazings: Animation Parameters  

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

Glazings Glazings Animation Simulation Parameters The Electrochromic Glazing Office Animation is created using an image compositing method whereby separate images of the office generated with only one source of illumination are added together in variable percentages to come up with the final image. This method assumes that the sources of illumination do not change position through the animation sequence. Although the sun does move approximately 5 degrees during the span of this 20 minute animation sequence, because this movement is not the focus of the simulation and does not significantly change the intensity of the solar exposure, it is ignored. This method takes advantage of the principal of the scalability of light to avoid the significant time involved in calculating separate Radiance renderings for each combination of sky condition (direct sun versus no direct sun) and electrochromic glazing transmission.

Laser sealed evacuated window glazings  

SciTech Connect

The design and fabrication of a highly insulating, evacuated window glazing have been investigated. A thermal network model has been used to parametrically predict the thermal performance of such a window. Achievable design, options are predicted to provide a glazing with a thermal conductance less than 0.6 W/m/sup 2/K (R > 10/sup 0/F ft/sup 2/ h/Btu) which is compact, lightweight, and durable. A CO/sub 2/ laser has been used to produce a continuous, leak tight, welded glass perimeter seal around 25 x 25 cm/sup 2/ test specimens. Various diameters of regularly spaced spherical support spacers were incorporated in the specimens as well as an integral SnO/sub 2/:F transparent, low emissivity coating for suppression of radiative heat transfer. Laser sealing rates of .06 cm/s were achieved at a 580/sup 0/C glass working temperature with 400 W of continuous wave (CW) laser power.

Rapid field testing of low-emittance coated glazings for product verification  

Science Conference Proceedings (OSTI)

This paper analyzes prospects for developing a test device suitable for field verification of the types of low-emittance (low-e) coatings present on high-performance window products. Test devices are currently available that can simply detect the presence of low-e coatings and that can measure other important characteristics of high-performance windows, such as the thickness of glazing layers or the gap in dual glazings. However, no devices have yet been developed that can measure gas concentrations or distinguish among types of coatings. This paper presents two optical methods for verification of low-e coatings. The first method uses a portable, fiber-optic spectrometer to characterize spectral reflectances from 650 to 1,100 nm for selected surfaces within an insulated glazing unit (IGU). The second method uses an infrared-light-emitting diode and a phototransistor to evaluate the aggregate normal reflectance of an IGU at 940 nm. Both methods measure reflectance in the near (solar) infrared spectrum and are useful for distinguishing between regular and spectrally selective low-e coatings. The infrared-diode/phototransistor method appears promising for use in a low-cost, hand-held field test device.

Test of fusible insulation for a proposed isotope power unit  

SciTech Connect

In support of the Isotope Kilowatt Program, an evaluation test of the full-scale simulated thermoelectric power generation system was made. The test was run with 6.5 in. of fusible insulation around the heat block-shield to determine the system heat losses. A loss of 10% of full power was obtained with the system operation at a heat block-shield surface temperature of 1100 deg F and an argon pressure of 1.0 psig. A test was run to determine the thermal coupling between the heat block-shield and 12 heat pipes with 12 simulated thermoelectric generators. A heat pipe condenser temperature of 1040 deg F was obtained at a heat block-shield surface temperature of 1150 deg F at a total power input of 34 kW. A loss-of-coolant accident test was made to determine the maximum fuel capsule surface temperature reached during a meltdown of the fusible insulation. The meltdown results yielded a maximum fuel capsule surface temperature of 2175 deg F and an equilibrium temperature of 2070 deg F. (auth)

Technology reviews: Glazing systems  

SciTech Connect

We present a representative review of existing, emerging, and future technology options in each of five hardware and systems areas in envelope and lighting technologies: lighting systems, glazing systems, shading systems, daylighting optical systems, and dynamic curtain wall systems. The term technology is used here to describe any design choice for energy efficiency, ranging from individual components to more complex systems to general design strategies. The purpose of this task is to characterize the state of the art in envelope and lighting technologies in order to identify those with promise for advanced integrated systems, with an emphasis on California commercial buildings. For each technology category, the following activities have been attempted to the extent possible: Identify key performance characteristics and criteria for each technology; determine the performance range of available technologies; identify the most promising technologies and promising trends in technology advances; examine market forces and market trends; and develop a continuously growing in-house database to be used throughout the project. A variety of information sources have been used in these technology characterizations, including miscellaneous periodicals, manufacturer catalogs and cut sheets, other research documents, and data from previous computer simulations. We include these different sources in order to best show the type and variety of data available, however publication here does not imply our guarantee of these data. Within each category, several broad classes are identified, and within each class we examine the generic individual technologies that fag into that class.

The development of an approximate dynamic analysis of insulating glass units  

E-Print Network (OSTI)

The goal of this thesis is to develop an approximate dynamic analysis of sealed insulating glass (IG) units subject to uniform blast loads, the formulation of which will be incorporated into a computer program that will be used as a tool to estimate their dynamic response. The formulation of this approximate dynamic analysis of IG units is achieved by modeling the unit with two equivalent single degree of freedom systems consisting of equivalent masses, equivalent structural stiffnesses, equivalent forces, and by incorporating air space compatibility relationships into this model. The equations of motion which define the behavior of this dynamic model are incorporated into a computer program that computes the dynamic response of an IG unit subjected to a prescribed blast loading. This response includes the displacements, velocities, and accelerations of the glass plates of the IG unit. The blast loading will be idealized in order to simplify the analysis. The program will approximate the positive pressure phase of a blast load with an equivalent triangular loading. IG units designed by existing methods will be analyzed using the program, and their performance evaluated. This analysis will not only provide valuable data on the behavior of the IG units to blast loadings, but will lend insight into the acceptability of the existing design approach. The results will also indicate the acceptability of the technique developed in this thesis as a tool in the design and analysis of IG units subject to blast loads.

Electrochromic Glazings: How they Work  

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

How they Work How they Work Electrochromic glazings have great potential to improve the energy efficiency and occupant comfort afforded by architectural windows. These smart windows can dynamically control light transmission by windows in buildings, automobiles, and aircraft. Electrochromic glazings are the most significant members of a family of chromogenic light-control technologies that includes large-area dispersed liquid crystals, dispersed particle windows, and photochromic and thermochromic materials. Electrochromic devices represent the most versatile window technology of this type, exhibiting the best combination of switching properties for chromogenic window applications. Electrochromic glazings typically have a change in visible light transmission from 10% to 70%, moderately fast switching times, and low dc power consumption. These glazings have memory, so they only need power to make a change in transmission. Electrochromic technology can be coupled with smart control systems to give constant lighting levels, blending artificial lighting with daylighting for improved building energy efficiency. Energy simulations of office buildings indicate that smart windows with lighting controls in arid climates can provide 30-40% energy savings over conventional windows. Savings are realized in cooling, lighting, and peak utility electric loads. Other benefits include smaller heating, ventilating, and air-conditioning (HVAC) systems and greater thermal and visual comfort.

Highly Insulating Window Technology  

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

Window Technology Window Technology Temperature differentials across a window, particularly with cold exterior environments in residential buildings, can lead to significant energy losses. Currently available low-emissivity coatings, gas-fills, and insulating frames provide significant energy savings over typical single or double glazed products. The EWC website provides information on how double glazed low-e gas-filled windows work as well as information on commercially available superwindows (three layer, multiple low-e coatings, high performance gas-fills). The next generation of highly insulating window systems will benefit from incremental improvements being made to current components (i.e. more insulating spacers and frame materials/designs, low-e coatings with improved performance properties). LBNL uses its experimental facilities and software tools to collaborate with window and glass industry representatives to better understand the impacts of new components on overall product performance.

Glazing materials for solar and architectural applications. Final report  

DOE Green Energy (OSTI)

This report summarizes five collaborative research projects on glazings performed by participants in Subtask C of IEA Solar Heating and Cooling Programme (SHC) Task 10, Materials Research and Testing. The projects include materials characterization, optical and thermal measurements, and durability testing of several types of new glazings Three studies were completed on electrochromic and dispersed liquid crystals for smart windows, and two were completed for low-E coatings and transparent insulation materials for more conventional window and wall applications. In the area of optical switching materials for smart windows, the group developed more uniform characterization parameters that are useful to determine lifetime and performance of electrochromics. The detailed optical properties of an Asahi (Japan) prototype electrochromic window were measured in several laboratories. A one square meter array of prototype devices was tested outdoors and demonstrated significant cooling savings compared to tinted static glazing. Three dispersed liquid crystal window devices from Taliq (USA) were evaluated. In the off state, these liquid crystal windows scatter light greatly. When a voltage of about 100 V ac is applied, these windows become transparent. Undyed devices reduce total visible light transmittance by only .25 when switched, but this can be increased to .50 with the use of dyed liquid crystals. A wide range of solar-optical and emittance measurements were made on low-E coated glass and plastic. Samples of pyrolytic tin oxide from Ford glass (USA) and multilayer metal-dielectric coatings from Interpane (Germany) and Southwall (USA) were evaluated. In addition to optical characterization, the samples were exposure-tested in Switzerland. The thermal and optimal properties of two different types of transparent insulation materials were measured.

Single, double and triple glazing are examined for use in passive solar Trombe walls and south facing windows. Net gains and losses are calculated employing regional weather data and annual contribution to heating load reduction is evaluated. The study concentrates on the reflectivity of each glass pane, including the dependence of reflectivity on the angle of incidence of the radiation, and resulting heat gains and losses. This facet of passive design heretofore has been inadequately treated as is shown to be significant. The marginal value of each additional pane is investigated with regard to heat gain, energy savings and total costs. Additionally, attention is given to the effects of Trombe wall energy storage.

A solar unit for the joint production of heating and refrigeration has been designed on the basis of glazed solution regeneration. The unit is similar to installations employing glazed solution regenerators for cooling alone. Equations are presented for calculating specific refrigeration and heating capacities as a function of such factors as meteorological conditions. The calculations show that the unit has good heating and refrigeration capacity and that optimum performance is obtained when water must be heated to 45 to 55 C.

SUPERGLASS. Engineering field tests - Phase 3. Production, market planning, and product evaluation for a high-thermal-performance insulating glass design utilizing HEAT MIRROR transparent insulation. Final report  

DOE Green Energy (OSTI)

HEAT MIRROR transparent window insulation consists of a clear polyester film two mils (.002'') thick with a thin, clear low-emissivity (.15) coating deposited on one side by state-of-the-art vacuum deposition processes. This neutral-colored invisible coating reflects long-wave infrared energy (heat). When mounted by being stretched with a 1/2'' air-gap on each side of the film, the resulting unit reduces heat loss by 60% compared to dual insulating glass. Southwall Corporation produces HEAT MIRROR transparent insulation and markets it to manufacturers of sealed insulating glass (I.G.) units and window and building manufacturers who make their own I.G. These companies build and sell the SUPERGLASS sealed glazing units. Units made and installed in buildings by six customers were visited. These units were located in many geographic regions, including the Pacific Northwest, Rocky Mountains, New England, Southeast, and West Coast. As much as could be obtained of their history was recorded, as was their current condition and performance. These units had been in place from two weeks to over a year. All of the units were performing thermally very well, as measured by taking temperature profiles through them and through adjacent conventional I.G. units. Some units had minor visual defects (attributed to I.G. assembly techniques) which are discussed in detail. Overall occupant acceptance was enthusiastically positive. In addition to saving energy, without compromise of optical quality or appearance, the product makes rooms with large glazing areas comfortable to be in in cold weather. All defects observed were present when built; there appears to be no in-field degradation of quality at this time.

Solar absorption in thick and multilayered glazings  

DOE Green Energy (OSTI)

Thick and multilayered glazings generally have a nonuniform distribution of absorbed solar radiation which is not taken into account by current methods for calculating the center of glass solar gain and thermal performance of glazing systems. This paper presents a more accurate method for calculating the distribution of absorbed solar radiation inside thick and multilayered glazings and demonstrates that this can result in a small but significant difference in steady-state temperature profile and Solar Heat Gain Coefficient for some types of glazing systems when compared to the results of current methods. This indicates that a more detailed approach to calculating the distribution of absorbed solar radiation inside glazings and resulting thermal performance may be justified for certain applications.

Development of a simplified thermal analysis procedure for insulating glass units  

E-Print Network (OSTI)

A percentage of insulating glass (IG) units break each year due to thermally induced perimeter stresses. The glass industry has known about this problem for many years and an ASTM standard has recently been developed for the design of monolithic glass plates for thermal stresses induced by solar irradiance. It is believed that a similar standard can be developed for IG units if a proper understanding of IG thermal stresses can be developed. The objective of this research is to improve understandings of IG thermal stresses and compare the IG thermal stresses with those that develop in monolithic glass plates given similar environmental conditions. The major difference between the analysis of a monolithic glass plate and an IG unit is energy exchange due to conduction, natural convection, and long wave radiation through the gas space cavity. In IG units, conduction, natural convection, and long wave radiation combine in a nonlinear fashion that frequently requires iterative numerical analyses for determining thermal stresses in certain situations. To simplify the gas space energy exchange, a numerical propagation procedure was developed. The numerical propagation procedure combines the nonlinear effects of conduction, natural convection, and long wave radiation into a single value. Use of this single value closely approximates the nonlinear nature of the gas space energy exchange and simplifies the numerical analysis. The numerical propagation procedure was then coupled with finite element analysis to estimate thermal stresses for both monolithic glass plates and IG units. It is shown that the maximum thermal stresses that develop in IG units increase linearly with input solar irradiance during the transient phase. It is shown that an initial preload stress develops under equilibrium conditions due to the thermal bridge effects of the spacer. It is shown that IG units develop larger thermal stresses than monolithic glass plates under similar environmental conditions. Finally, it is shown that the use of low-e coatings increase IG thermal stresses and that the location of low-e coating as well as environmental conditions affect which glass plate develops larger thermal stresses.

Advances in glazing materials for windows  

SciTech Connect

No one type of glazing is suitable for every application. Many materials are available that serve different purposes. Moreover, consumers may discover that they need two types of glazing for a home because of the directions that the windows face and the local climate. To make wise purchases, consumers should first examine their heating and cooling needs and prioritize desired features such as daylighting, solar heating, shading, ventilation, and aesthetic value. Research and development into types of glazing have created a new generation of materials that offer improved window efficiency and performance for consumers. While this new generation of glazing materials quickly gains acceptance in the marketplace, the research and development of even more efficient technology continues.

Thermal performance measurements of sealed insulating glass units with low-E coatings using the MoWiTT (Mobile Window Thermal Test) field-test facility  

SciTech Connect

Using data obtained in a mobile field-test facility, measured performance of clear and low-emissivity double-glazing units is presented for south-facing and north-facing orientations. The changes in U-value and shading coefficient resulting from addition of the low-E coating are found to agree with theoretical expectations for the cold spring test conditions. Accurate nighttime U-values were derived from the data and found to agree with calculations. Expected correlation between U-value and wind speed was not observed in the data; a plausible experimental reason for this is advanced.

Durability of Polymeric Glazing and Absorber Materials  

DOE Green Energy (OSTI)

The Solar Heating and Lighting Program has set the goal of reducing the cost of solar water heating systems by at least 50%. An attractive approach to such large cost reduction is to replace glass and metal parts with less-expensive, lighter-weight, more-integrated polymeric components. The key challenge with polymers is to maintain performance and assure requisite durability for extended lifetimes. The objective of this task is to quantify lifetimes through measurement of the optical and mechanical stability of candidate polymeric glazing and absorber materials. Polycarbonate sheet glazings, as proposed by two industry partners, have been tested for resistance to UV radiation with three complementary methods. Incorporation of a specific 2-mil thick UV-absorbing screening layer results in glazing lifetimes of at least 15 years; improved screens promise even longer lifetimes. Proposed absorber materials were tested for creep and embrittlement under high temperature, and appear adequate for planned ICS absorbers.

Vacuum Window Glazings for Energy-Efficient Buildings : Summary Report.  

SciTech Connect

The technical feasibility of a patented, laser-welded, evacuated insulating window was studies. The window has two edge-sealed sheets of glass separated by 0.5-mm glass spheres spaced 30 mm apart in a regular array. A highly insulating frame is required and several designs were analyzed. The vacuum window's combination of high solar transmittance and low thermal conductance makes it superior to many other windows in cold climates. In the US Pacific Northwest, the vacuum window could save about 6 MJ of heating energy annually per square meter of window in comparison to conventional, double-glazed windows. A large, vacuum laser-welding facility was designed and installed to conduct glass welding experiments and to fabricate full-sized vacuum windows. Experiments confirmed the feasibility of laser-sealing glass in vacuum but identified two difficulties. Under some circumstances, bubbles of dissolved gases form during welding and weaken the seal. Glass also vaporizes and contaminates the laser beam steering mirror. A novel moving metal foil mirror was developed to circumvent the contamination problem, but is has not yet been used to complete welding experiments and fabricate full-sized vacuum windows. 63 refs., 53 figs., 19 tabs.

The next generation of advanced windows will involve a "smart-coating" technology where the optical and solar properties can be dynamically controlled. The performance of such coating is ultimately linked to its materials properties such as chemical composition and microstructure. These properties are directly influenced by the deposition process conditions. A promising dynamic windows technology is based upon the electrochromism process.

This paper presents a brief-case packaged program, networked by phone to a central computer which provides an on-the-spot window load study and printout. This commercial energy simulation report (ESPCOM), five pages long, can predict actual window energy consumption in commercial buildings to within two percent annually. It is designed for buildings which have at least 5000 square feet of surface glass. ESPCOM considers a building's architectural, engineering and operational data, then determines the five-year estimated savings which can be expected of the present glazing system versus the system enhanced with any three of a series of 17 professional grade insulating films.

Development of 1200-kV compressed-gas-insulated transmission and substation equipment in the United States  

SciTech Connect

Major research and development (R and D) programs for the development of sulfur hexafluoride (SF/sub 6/) compressed-gas-insulated (CGI) equipment for ultrahighvoltage (uhv) application at 100-1200 kV have been under way independently in both the United States and Japan. The CGI transmission and substation equipment under study and development in these countries has included the surge arrester, circuit breaker, CGI transmission bus, disconnect and ground switches, and an air-SF/sub 6/ termination. The US CGI program has also included development of a power transformer, shunt reactor, voltage- and current-sensing instrumentation, and a line trap, all for 1200-kV application. This paper presents the overall status of development of CGI substation equipment for uhv application in the United States. It describes the major CGI components developed, highlights their key design aspects, indicates the present status of development and testing, and addresses the work remaining to establish final design consepts. The paper also includes 23 references, a number of which have not been widely distributed or included in any of the recently published bibliographies of uhv substation equipment.

Daylight, glazing, and building energy minimization  

SciTech Connect

This paper examines the effects of glazing on thermal loads. Annual heating, cooling, and lighting loads are reported for a window office in a Houston building in which five types of glass were simulated. The glass parameters are U-value, shading coeffient, visible band transmittance, and inside reflectance; therefore, a change in glass directly affected the solar heat gain. Once again, it was assumed that the artificial lights were continuously adjustable, that is, the lights provide the difference between the illumination required (user specified) and that provided by daylight.

The buildings are monitored by the National Solar Data Network (NSDN) whose system is shown schematically. Tests show that no high cost direct gain solar systems were economically viable without movable insulation. Monitored seasonal performance of the five sites showed three good, and two poor performances. Each case is specified in detail.

An expert system for window glazing design  

SciTech Connect

An integrated expert system was developed to facilitate the design of window glass for structural strength, hydrostatic loads, sound attenuation, and solar control. The integrated software consists of a text-based interface, a rule-based expert system, and two neural networks. The text of a glazing design guide is linked by related topics and concepts. The software's design feature lets the user enter design parameters for the window choice via an interactive consultation in to a rule-based expert system that critiques the design. The technical aspects of the glass's structural strength are based primarily on linear methods published by the American Architectural Manufacturers Association Statistical correlations for the new nonlinear failure prediction for glass strength are used to automatically design for the minimum glass thickness required to withstand a specified load. Neural networks estimate values for sound attenuation and solar transmission characteristics from laboratory test data on selected glass constructions.

Energy efficiency of a dynamic glazing system  

SciTech Connect

The reduction of air-conditioning energy consumptions is one of the main indicators to act on when improving the energy efficiency in buildings. In the case of advanced technological buildings, a meaningful contribution to the thermal loads and the energy consumptions reduction could depend on the correct configuration and management of the envelope systems. In recent years, the architectural trend toward highly transparent all-glass buildings presents a unique challenge and opportunity to advance the market for emerging, smart, dynamic window and dimmable daylighting control technologies (). A prototype dynamic glazing system was developed and tested at ITC-CNR; it is aimed at actively responding to the external environmental loads. Both an experimental campaign and analyses by theoretical models were carried out, aimed at evaluating the possible configurations depending on different weather conditions in several possible places. Therefore, the analytical models of the building-plant system were defined by using a dynamic energy simulation software (EnergyPlus). The variables that determine the system performance, also influenced by the boundary conditions, were analysed, such as U- and g-value; they concern both the morphology of the envelope system, such as dimensions, shading and glazing type, gap airflow thickness, in-gap airflow rate, and management, in terms of control algorithm parameters tuning fan and shading systems, as a function of the weather conditions. The configuration able to provide the best performances was finally identified by also assessing such performances, integrating the dynamic system in several building types and under different weather conditions. The dynamic envelope system prototype has become a commercial product with some applications in facade systems, curtain walls and windows. The paper describes the methodological approach to prototype development and the main results obtained, including simulations of possible applications on real buildings. (author)

Improved DC Gun Insulator  

SciTech Connect

Many user facilities such as synchrotron light sources and free electron lasers require accelerating structures that support electric fields of 10-100 MV/m, especially at the start of the accelerator chain where ceramic insulators are used for very high gradient DC guns. These insulators are difficult to manufacture, require long commissioning times, and have poor reliability, in part because energetic electrons bury themselves in the ceramic, creating a buildup of charge and causing eventual puncture. A novel ceramic manufacturing process is proposed. It will incorporate bulk resistivity in the region where it is needed to bleed off accumulated charge caused by highly energetic electrons. This process will be optimized to provide an appropriate gradient in bulk resistivity from the vacuum side to the air side of the HV standoff ceramic cylinder. A computer model will be used to determine the optimum cylinder dimensions and required resistivity gradient for an example RF gun application. A ceramic material example with resistivity gradient appropriate for use as a DC gun insulator will be fabricated by glazing using doping compounds and tested.

Design and Evaluation of Daylighting Applications of Holographic Glazings Design and Evaluation of Daylighting Applications of Holographic Glazings Title Design and Evaluation of Daylighting Applications of Holographic Glazings Publication Type Report LBNL Report Number LBNL-44167 Year of Publication 1996 Authors Papamichael, Konstantinos M., Charles K. Ehrlich, and Gregory J. Ward Call Number LBNL-44167 Abstract When combined with appropriate electric lighting dimming controls, the use of daylight for ambient and task illumination can significantly reduce energy requirements in commercial buildings. While skylights can effectively illuminate any part of one-story buildings, conventional side windows can illuminate only a 15 ft - 20 ft (4.6 m - 6.1 m) depth of the building perimeter. Even so, the overall efficacy of daylight is limited, because side windows produce uneven distributions of daylight. Achieving adequate illumination at distances further away from the window results in excessive illumination near the window, which increases cooling loads from the associated solar heat gain. As a result, the use of larger apertures and/or higher transmittance glazings, to introduce daylight deeper than 15 ft - 20 ft (4.6 m - 6.1 m), may prove ineffective with respect to saving energy, because cooling load penalties may exceed the electric lighting savings.

Performance of High-Performance Glazing in IECC Compliant Building Simulation Model  

E-Print Network (OSTI)

Current specifications for glazing in the 2000 IECC code adopted by Texas imply the use of low-E glazing. However, the trends in the development of highperformance glazing technology indicate that windows have the potential to provide net positive energy benefits making it inevitable for future versions of the IECC to incorporate high-performance glazing. This study examines the performance of a number of such glazing options when incorporated in the IECC compliant residential building. The results show that in some cases the resultant energy consumption obtained from installing high-performance windows was lower than the energy consumption of a base-case windowless house (Approximately 6% total energy savings, and 40% heating).

Aerogel: a transparent insulator for solar applications  

SciTech Connect

Aerogel is a transparent, low density, insulating material suitable for a variety of solar applications. Significant energy savings can be realized by using aerogel for a window glazing material. Other possible applications include solar collector covers, transparent insulating jackets for direct gain passive solar devices, and situations that require both transparency and good insulation. Because silica aerogel has a low density (2 to 10% solid), it has a thermal conductivity as low as 0.014 W/m/sup 0/K without evacuation, and if evacuated, lower than 0.006 W/m/sup 0/K. It provides a clear view with only slight coloring due to its weak and nearly isotropic scattering of light. This paper describes significant progress made in the past year at our laboratory in the development of aerogel. We have improved the transparency, developed new preparation methods using less toxic materials, and initiated successful experiments in drying alcogels at near ambient temperature. Optical transmission, light scattering, and electron microscopy data show that CO/sub 2/ supercritical drying of alcogels produces aerogels similar in quality to those produced by high temperature supercritical drying. These advances make the commercial production of aerogel much more feasible.

Impact of Different Glazing Systems on Cooling Load of a Detached Residential Building at Bhubaneswar, India  

E-Print Network (OSTI)

For detached residential buildings located in the tropics, it is more challenging and difficult to deal with the space cooling load due to hot and humid climates. In this paper, daily and monthly computer simulations of solar heat gain and cooling load for a detached residential building are carried out using Design Builder software. Different glazing systems ranging from single glazed clear glass to double glaze with electro chromic reflective colored have been analyzed in terms of their impact on solar heat gain and cooling load. The simulation results show reductions in solar heat gain, cooling load and better thermal comfort can be achieved using proper glazing systems for a specific orientation of the building. The significance of these results stems from the fact that they are obtained under local weather conditions, a matter of importance to building architects, designers, contractors, and builders as well as air conditioning equipment manufacturers.

Joint China-United States Report for Year 1 Insulation Materials and Systems Project Area Clean Energy Research Center Building Energy Efficiency (CERC-BEE)  

Science Conference Proceedings (OSTI)

In November of 2009, the presidents of China and the U.S. announced the establishment of the Clean Energy Research Center (CERC). This broad research effort is co-funded by both countries and involves a large number of research centers and universities in both countries. One part of this program is focused on improving the energy efficiency of buildings. One portion of the CERC-BEE was focused on building insulation systems. The research objective of this effort was to Identify and investigate candidate high performance fire resistant building insulation technologies that meet the goal of building code compliance for exterior wall applications in green buildings in multiple climate zones. A Joint Work Plan was established between researchers at the China Academy of Building Research and Oak Ridge National Laboratory. Efforts in the first year under this plan focused on information gathering. The objective of this research program is to reduce building energy use in China via improved building insulation technology. In cold regions in China, residents often use inefficient heating systems to provide a minimal comfort level within inefficient buildings. In warmer regions, air conditioning has not been commonly used. As living standards rise, energy consumption in these regions will increase dramatically unless significant improvements are made in building energy performance. Previous efforts that defined the current state of the built environment in China and in the U.S. will be used in this research. In countries around the world, building improvements have typically followed the implementation of more stringent building codes. There have been several changes in building codes in both the U.S. and China within the last few years. New U.S. building codes have increased the amount of wall insulation required in new buildings. New government statements from multiple agencies in China have recently changed the requirements for buildings in terms of energy efficiency and fire safety. A related issue is the degree to which new standards are adopted and enforced. In the U.S., standards are developed using a consensus process, and local government agencies are free to implement these standards or to ignore them. For example, some U.S. states are still using 2003 versions of the building efficiency standards. There is also a great variation in the degree to which the locally adopted standards are enforced in different U.S. cities and states. With a more central process in China, these issues are different, but possible impacts of variable enforcement efficacy may also exist. Therefore, current building codes in China will be compared to the current state of building fire-safety and energy-efficiency codes in the U.S. and areas for possible improvements in both countries will be explored. In particular, the focus of the applications in China will be on green buildings. The terminology of 'green buildings' has different meanings to different audiences. The U.S. research is interested in both new, green buildings, and on retrofitting existing inefficient buildings. An initial effort will be made to clarify the scope of the pertinent wall insulation systems for these applications.

Membranes Improve Insulation Efficiency  

E-Print Network (OSTI)

It has been determined from extensive tests involving test models and home attics that loose fill and fiber batt insulation does not function as expected by the industry. The reason for this deficiency is current test methods do not accurately predict the magnitude of air infiltration into fiber insulation as used in home attics, radiant heat infiltration into the insulation during summer, or radiant heat loss through the insulation during winter conditions. The use of (1) moisture permeable membranes over the insulation, and (2) layered membranes between fiber batts to form closed cells in the insulation both dramatically improve the efficiency of the fiber insulation. The efficiency of this insulation will be improved to an even greater degree if these membranes reflect radiant heat as well as reduce convection air currents. Extensive tests have also been conducted which show that if moisture permeable membranes are used over fiber insulation, the moisture content of the insulation will be reduced.

Highly Insulating Windows with a U-value less than 0.6 W/m2K  

Science Conference Proceedings (OSTI)

U.S. households rely primarily on three sources of energy: natural gas, electricity, and fuel oil. In the past several decades, electricity consumption by households has grown dramatically, and a significant portion of electricity used in homes is for lighting. Lighting includes both indoor and outdoor lighting and is found in virtually every household in the United States. In 2001, according to the US Energy Information Administration, lighting accounted for 101 billion kWh (8.8 percent) of U.S. household electricity use. Incandescent lamps, which are commonly found in households, are highly inefficient sources of light because about 90 percent of the energy used is lost as heat. For that reason, lighting has been one focus area to increase the efficiency of household electricity consumption. Windows have several functions, and one of the main functions is to provide a view to the outside. Daylighting is another one of windows main functions and determines the distribution of daylight to a space. Daylighting windows do not need to be transparent, and a translucent daylighting window is sufficient, and often desired, to diffuse the light and make the space more environmentally pleasing. In homes, skylights are one source of daylighting, but skylights are not very energy efficient and are inseparably linked to solar heat gain. In some climates, added solar heat gains from daylighting may be welcome; but in other climates, heat gain must be controlled. More energy efficient skylights and daylighting solutions, in general, are desired and can be designed by insulating them with aerogels. Aerogels are a highly insulating and transparent material in its pure form. The overall objective for this project was to prepare an economical, translucent, fiber-reinforced aerogel insulation material for daylighting applications that is durable for manufacturing purposes. This advanced insulation material will increase the thermal performance of daylighting windows, while satisfying constraints such as durability, cost, user acceptance, size limits, and environmental safety concerns. The energy efficient daylighting window will consist of a translucent and resilient aerogel panel sandwiched between glass panes in double glazed windows. Compared to the best windows available today, the double glazed translucent windows with 1/2-inch aerogel inserts will have a U-value of 1.2 W/m{sup 2} K (0.211 BTU/ft{sup 2} h F) without any coating or low conductivity fill gases. These windows will be more effective than the windows with an Energy Star rating of U-2 W/m{sup 2} K and could be made even more efficient by using low-e coated glass glazings and inert gas fills. This report summarizes the work accomplished on Cooperative Agreement DE-FC26-03NT41950. During this project, Aspen Aerogels made transparent and translucent aerogels from TMOS and TEOS. We characterized the transparency of the aerogels, reinforced the transparent aerogels with fibers and prepared large translucent aerogel panels and blankets. We also conducted an initial market study for energy efficient translucent windows. A lab-scale process was developed that could be scaled-up to manufacture blankets of these translucent aerogels. The large blankets prepared were used to fabricate prototype translucent windows and skylights. The primary goal of this project was to develop transparent, resilient, hydrophobic silica aerogels that have low thermal conductivities (R-10/inch) to be used to produce aerogel insulated double-glazing windows with a U value of 0.6 W/m{sup 2}K. To meet this objective we developed a process and equipment to produce blankets of translucent, hydrophobic aerogel. We focused on silica, organically-modified silica aerogels (Ormosils), and fiber reinforced silica aerogels due to the appreciable expertise in silica sol-gel processing available with the personnel at Aspen Aerogels, and also due to the quantity of knowledge available in the scientific literature. The project was conducted in three budget periods, herein called BP1, BP2 and BP3.

Recovery Act: Electrochromic Glazing Technology: Improved Performance, Lower Price  

SciTech Connect

The growing dependency of the US on energy imports and anticipated further increases in energy prices reinforce the concerns about meeting the energy demand in the future and one element of a secure energy future is conservation. It is estimated that the buildings sector represents 40% of the US's total energy consumption. And buildings produce as much as one third of the greenhouse gas emissions primarily through fossil fuel usage during their operational phase. A significant fraction of this energy usage is simply due to inefficient window technology. Electrochromic (EC) windows allow electronic control of their optical properties so that the transparency to light can be adjusted from clear to dark. This ability to control the amount of solar energy allowed into the building can be advantageously used to minimize lighting, heating and air conditioning costs. Currently, the penetration of EC windows into the marketplace is extremely small, and consequently there is a huge opportunity for energy savings if this market can be expanded. In order to increase the potential energy savings it is necessary to increase the quantity of EC windows in operation. Additionally, any incremental improvement in the energy performance of each window will add to the potential energy savings. The overall goals of this project were therefore to improve the energy performance and lower the cost of dynamic (EC) smart windows for residential and commercial building applications. This project is obviously of benefit to the public by addressing two major areas: lowering the cost and improving the energy performance of EC glazings. The high level goals for these activities were: (i) to improve the range between the clear and the tinted state, (ii) reduce the price of EC windows by utilizing lower cost materials, (iii) lowering the U-Value1 SAGE Electrochromics Inc. is the only company in the US which has a track record of producing EC windows, and presently has a small operational factory in Faribault MN which is shipping products throughout the world. There is a much larger factory currently under construction close by. This project was targeted specifically to address the issues outlined above, with a view to implementation on the new high volume manufacturing facility. Each of the Tasks which were addressed in this project is relatively straightforward to implement in this new facility and so the benefits of the work will be realized quickly. , and (iv) ensure the proposed changes have no detrimental effect to the proven durability of the window. The research described here has helped to understand and provide solutions to several interesting and previously unresolved issues of the technology as well as make progress in areas which will have a significant impact on energy saving. In particular several materials improvements have been made, and tasks related to throughput and yield improvements have been completed. All of this has been accomplished without any detrimental effect on the proven durability of the SageGlass EC device. The project was divided into four main areas: 1. Improvement of the Properties of the EC device by material enhancements (Task 2); 2. Reduce the cost of production by improving the efficiency and yields of some key manufacturing processes (Task 3); 3. Further reduce the cost by significant modifications to the structure of the device (Task 4); 4. Ensure the durability of the EC device is not affected by any of the changes resulting from these activities (Task 5). A detailed description of the activities carried out in these areas is given in the following report, along with the aims and goals of the work. We will see that we have completed Tasks 2 and 3 fully, and the durability of the resulting device structure has been unaffected. Some of Task 4 was not carried out because of difficulties with integrating the installation of the required targets into the production coater due to external constraints not related to this project. We will also see that the durability of the devices produced as a result of this work was

INCREASING YIELDS AND BROADENING MARKETS: PROCESS INNOVATIONS IN THE MANUFACTURING OF ENERGY-SAVING WINDOW GLAZINGS  

Science Conference Proceedings (OSTI)

The goal of this project was to develop and implement advanced thin film process technology which would significantly improve the manufacturability of both static and dynamic high performance energy saving coatings for windows. The work done has been aimed at improvements to the process that will result in increases in yield, and this was divided into four main areas, dealing with improvements in substrate preparation methods, reductions in the incidence of problems caused by particulate contamination, use of in-situ optical monitoring to improve process control, and overall system integration to enable simplified, and therefore lower cost operation. Significant progress has been made in each of the areas. In the area of substrate preparation, the enhanced washing techniques which have been developed, in combination with a new inspection technique, have resulted in significant reductions in the number of EC devices which are rejected because of substrate problems. Microscopic inspection of different defects in electrochromic devices showed that many were centered on particles. As a result, process improvements aimed at reducing the incidence of particles throughout the entire process have been implemented. As a result, the average number of defects occurring per unit area has been significantly reduced over the period of this project. The in-situ monitoring techniques developed during this project have become an indispensable part of the processing for EC devices. The deposition of several key layers is controlled as a result of in-situ monitoring, and this has facilitated significant improvements in uniformity and repeatability. Overall system integration has progressed to the stage where the goal of a closed-loop monitoring and control system in within reach, and it is anticipated that this will be achieved during the scale-up phase. There has been a clear increase in the yield occurring over the period of this project (Sept 1999 to September 2003), which is attributable to a range of process improvements implemented as a result of this work. It is anticipated that the yield will increase further as a result of these ongoing programs. The manufacturability of these advanced glazing systems has also been significantly improved, by a variety of different measures such as in-situ monitoring, system integration, and measurements taken to reduce the incidence of defects caused by contamination. It is therefore anticipated that the transfer of this performance to the new coating equipment to be introduced during scale-up to the first manufacturing plant will be reasonably straightforward.

Reflective Insulation Handbook.  

Science Conference Proceedings (OSTI)

When reflective-foil insulation manufacturers wanted the Bonneville Power Administration (BPA) to include their products in the Residential Weatherization Program, they lacked conclusive test data to prove that their products met program specifications. Reflective foils lacked widespread acceptance because of uncertainty about their insulation values. BPA discovered that the Department of Energy (DOE) and Oak Ridge National Laboratory (ORNL) was preparing a study to test how well reflective foils reduced horizontal heat flow. Because the insulation value of reflective foils depends upon the direction of heat flow, BPA provided additional funding to test their effectiveness in reducing upward and downward heat flow and to produce this Handbook. The objectives of this study were to develop acceptable test and evaluation methods, produce an initial data base of idealized reflective-foil insulation systems, extend this data base to a limited number of commercially available products to develop and test analytical models to predict thermal performance and develop a Reflective Insulation Handbook for homeowners and insulation contractors. This handbook describes how heat is transferred; the function of an insulation; what reflective insulation is; types of reflective insulation; where it can be used; installation procedures; thermal performance; and useful sources of information. 10 figs., 2 tabs.

Measurement of single and double glazing thermal performance under realistic conditions using the mobile window thermal test (MoWiTT) facility  

SciTech Connect

The thermal performance of single glazing, clear double glazing, and double glazing with a low-emissivity coating was measured in both south-facing and north-facing orientations under realistic field conditions using the new MoWiTT field test facility. The time-dependent net heat flow through each fenestration was found to be consistent with the predictions of the standard simplified heat transfer model, provided that an angle-dependent shading coefficient is used and diffuse solar gain is included in the calculation. Summer-condition average U-values were derived for each glazing type and were found to agree with the expected values for both types of double glazing. The measured U-value for single glazing was lower than predicted.

The inner and outer layers of glass are both clear and separated by an air gap. Double glazing, compared to single glazing, cuts heat loss in half due to the insulating air space between the glass layers. In addition to reducing the heat flow, a double-glazed unit with clear glass will allow the transmission of high visible light and high solar heat gain. Double Clear Center of Glass Properties Note: These values are for the center of glass only. They should only be used to compare the effect of different glazing types, not to compare total window products. Frame choice can drastically affect performance.

Pipe Insulation Economies  

E-Print Network (OSTI)

Pipe Insulation Economies is a computer program written in IBM basic to simplify the economic insulation thickness for an insulated pipe. Many articles have been written on this subject, from simple nomographs to a small book written in 1976 by the Federal Energy Administration, called "Economic Thickness for Industrial Insulation (ETI)." This paper is meant to fall somewhere between these extremes without sacrificing the accuracy necessary for economic considerations. Within this text, insulation is dealt with not as a material but as a method to slow heat transfer. To simplify the various mechanisms by which heat is transferred, the variable "thermal conductivity" is used. This is modeled for average insulation temperature. Another variable which has caused problems in the past is the ambient air film coefficient, or surface resistance. This program deals with this coefficient by making an initial assumption, then using an iterative process to refine the actual values before making the economic calculations. The program will use the input data to determine first of all the heat loss in BTU per hr/ft. of pipe. Using this result the lowest annual cost, therefore the most economical insulation thickness, is determined.

Electricity bills, oil bills, gas bills - all homeowners pay for one or more of these utilities, and wish they paid less. Often many of us do not really know how to control or reduce our utility bills. We resign ourselves to high bills because we think that is the price we have to pay for a comfortable home. We encourage our children to turn off the lights and appliances, but may not recognize the benefits of insulating the attic. This publication provides facts relative to home insulation. It discusses where to insulate, what products to use, the decision making process, installation options, and sources of additional information.

Vacuum foil insulation system  

DOE Patents (OSTI)

In a multifoil thermal insulation package having a plurality of concentric cylindrical cups, means are provided for reducing heat loss from the penetration region which extends through the cups. At least one cup includes an integral skirt extending from one end of the cup to intersection with the penetration means. Assembly of the insulation package with the skirted cup is facilitated by splitting the cup to allow it to be opened up and fitted around the other cups during assembly.

Influence of glazing selection on commercial building energy performance in hot and humid climates  

SciTech Connect

This paper presents a comparative study in which commercial building perimeter zone electric energy (cooling, lighting, fan) and peak electric demand are analyzed as a function of window glazing type, with a particular emphasis on the use of glazings with wavelength-selective solar-optical properties. The DOE-2 energy analysis simulation program was used to generate a data base of the electric energy requirements of a prototypical office building module located in Singapore. Algebraic expressions derived by multiple regression techniques permitted a direct comparison of those parameters that characterize window performance in hot and humid climates: orientation, size, and solar-optical properties. Also investigated were the effects of exterior and interior shading devices, as well as interior illuminance level, power density, and lighting controls to permit the use of daylighting. These regression equations were used to compare the energy implications of conventional window designs and newer designs in which the type of coating and substrate were varied. The analysis shows the potential for substantial savings through combined solar load control and lighting energy use reduction with daylighting.

The impact of glazing selection on residential duct design and comfort  

SciTech Connect

The vast majority of residential HVAC contractors design and install duct systems using rules of thumb and design guidelines based on obsolete assumptions about house thermal characteristics. Perhaps the most widely accepted rule of thumb is that conditioned air should be delivered at the building perimeter to control the load and achieve acceptable comfort at the windows. The basis for this rule dates back to testing performed in uninsulated houses and laboratory facilities with single-glazed windows. Through computer modeling, field testing, and laboratory testing, initial guidelines have been developed to allow the builder or HVAC contractor to forsake perimeter duct distribution when certain levels of energy efficiency are met, which typically involves better performing windows than are typically selected. The concept of minimized duct design (MDD) affords the opportunity to mitigate many of the problems associated with ductwork, including energy waste, poor indoor air quality, and compromised combustion appliance safety, while encouraging the use of higher performance glazing. Analysis shows that in many cases the cost savings in the ductwork will offset the added cost of the window upgrade.

Detailed thermal performance data on conventional and highly insulating window systems  

SciTech Connect

Data on window heat-transfer properties (U-value and shading coefficient (SC)) are usually presented only for a few window designs at specific environmental conditions. With the introduction of many new window glazing configurations (using low-emissivity coatings and gas fills) and the interest in their annual energy performance, it is important to understand the effects of window design parameters and environmental conditions on U and SC. This paper discusses the effects of outdoor temperature, wind speed, insolation, surface emittance, and gap width on the thermal performance of both conventional and highly insulating windows. Some of these data have been incorporated into the fenestration chapter of the ''ASHRAE Handbook - 1985 Fundamentals.'' The heat-transfer properties of multiglazed insulating window designs are also presented. These window systems include those having (1) one or more low-emittance coatings; (2) low-conductivity gas-fill or evacuated cavities; (3) a layer of transparent silica aerogel, a highly insulating microporous material; or (4) combinations of the above. Using the detailed building energy analysis program, DOE 2.1B, we show that these systems, which all maintain high solar transmittance, can add more useful thermal energy to a space than they lose, even in a northern climate. Thus, in terms of seasonal energy flows, these fenestration systems out-perform insulated walls or roofs.

State-of-the-Art Highly Insulating Window Frames - Research and Market Review  

DOE Green Energy (OSTI)

This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m{sup 2}K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC. The frame research review also shows examples of window frames developed in order to increase the energy efficiency of the frames and the glazings which the frames are to be used together with. The authors find that two main tracks are used in searching for better solutions. The first one is to minimize the heat losses through the frame itself. The result is that conductive materials are replaced by highly thermal insulating materials and air cavities. The other option is to reduce the window frame area to a minimum, which is done by focusing on the net energy gain by the entire window (frame, spacer and glazing). Literature shows that a window with a higher U-value may give a net energy gain to a building that is higher than a window with a smaller U-value. The net energy gain is calculated by subtracting the transmission losses through the window from the solar energy passing through the windows. The net energy gain depends on frame versus glazing area, solar factor, solar irradiance, calculation period and U-value. The frame research review also discusses heat transfer modeling issues related to window frames. Thermal performance increasing measures, surface modeling, and frame cavity modeling are among the topics discussed. The review shows that the current knowledge gives the basis for improving the calculation procedures in the calculation standards. At the same time it is room for improvement within some areas, e.g. to fully understand the natural convection effects inside irregular vertical frame cavities (jambs) and ventilated frame cavities.

Calorimetric measurements of inward-flowing fraction for complex glazing and shading systems  

DOE Green Energy (OSTI)

This paper presents a calorimetric measurement of layer-specific inward-flowing fractions of absorbed solar energy for a number of geometric configurations common in fenestrations with shading. The inward-flowing fractions are found to be relatively insensitive to exterior conditions. Results for an interior venetian blind over double glazing agree with thermal model calculations in literature, and are the first layer-specific verification of these calculations. It is argued that a data base of these inward-flowing fractions for a suitably broad class of geometries will make possible the determination of solar heat gain coefficient from noncalorimetric measurements of solar-optical properties of complex fenestration components, a procedure termed solar-thermal separation.

Porous insulation in HVAC systems  

Science Conference Proceedings (OSTI)

Porous insulation used to line the air stream surfaces of HVAC equipment provides a locus for the accumulation of dirt and debris. Dirt and debris are hydrophilic and the insulation on the air stream surfaces of mechanical cooling systems thus provides a niche for mold growth. The mold growing on porous insulation unlike moldy debris on a hard surface such as sheetmetal cannot be removed by duct cleaning. Actions for proactively preventing biocontamination of HVAC insulation include the following. (1) Porous insulation shall not be used to line the air stream surfaces of HVAC plenums where wetting is likely such as in the vicinity of cooling coils

Highly Insulating Glazing Systems using Non-Structural Center Glazing Highly Insulating Glazing Systems using Non-Structural Center Glazing Layers Dariush Arasteh, Howdy Goudey, and Christian Kohler Lawrence Berkeley National Laboratory ABSTRACT Three layer insulating glass units with two low-e coatings and an effective gas fill are known to be highly insulating, with center-of-glass U-factors as low as 0.57 W/m 2 -K (0.10 Btu/h-ft 2 -°F). Such units have historically been built with center layers of glass or plastic which extend all the way through the spacer system. This paper shows that triple glazing systems with non-structural center layers which do not create a hermetic seal at the edge have the potential to be as thermally efficient as standard designs, while potentially removing some of the production and product integration issues that have

Highly Insulating Windows - Cost  

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

Cost Cost The following is an estimate of the cost effective incremental cost of highly-insulating windows (U-factor=0.20 Btu/hr-ft2-F) compared to regular ENERGY STAR windows (U-factor 0.35 Btu/hr-ft2-F). Energy savings from lower U-factors were simulated with RESFEN over an assumed useful window life of 25 years. To determine the maximum incremental cost at which highly-insulating windows would still be cost-effective, we used a formula used by many utility companies to calculate the cost of saved energy from energy efficiency programs, based on the programs' cost and savings. We turned this formula around so that the cost of saved energy equals the present energy prices in the studied locations, whereas the program cost (the incremental cost of the windows) is the dependent variable. By entering 5%

Insulated pipe clamp design  

SciTech Connect

Thin wall large diameter piping for breeder reactor plants can be subjected to significant thermal shocks during reactor scrams and other upset events. On the Fast Flux Test Facility, the addition of thick clamps directly on the piping was undesired because the differential metal temperatures between the pipe wall and the clamp could have significantly reduced the pipe thermal fatigue life cycle capabilities. Accordingly, an insulated pipe clamp design concept was developed. The design considerations and methods along with the development tests are presented. Special considerations to guard against adverse cracking of the insulation material, to maintain the clamp-pipe stiffness desired during a seismic event, to minimize clamp restraint on the pipe during normal pipe heatup, and to resist clamp rotation or spinning on the pipe are emphasized.

Consider insulation reliability  

SciTech Connect

This paper reports that when calcium silicate and two brands of mineral wool were compared in a series of laboratory tests, calcium silicate was more reliable. And in-service experience with mineral wool at a Canadian heavy crude refinery provided examples of many of the lab's findings. Lab tests, conducted under controlled conditions following industry accepted practices, showed calcium silicate insulation was stronger, tougher and more durable than the mineral wools to which it was compared. For instance, the calcium silicate insulation exhibited only some minor surface cracking when heated to 1,200[degrees]F (649[degrees]C), while the mineral wools suffered binder burnout resulting in sagging, delamination and a general loss of dimensional stability.

Energy Performance and Comfort Level in High Rise and Highly Glazed Office Buildings  

E-Print Network (OSTI)

Thermal and visual comfort in buildings play a significant role on occupants' performance but on the other hand achieving energy savings and high comfort levels can be a quite difficult task especially in high rise buildings with highly glazed facades. Many studies suggest that the energy needed to keep the interior conditions at required comfort levels in buildings depends on several factors such as physical and optical properties of building elements, indoor and outdoor climate and behaviour of the occupants, etc. Moreover depending on the different orientation of building facade, the impact of these parameters might vary. The buildings are usually designed without paying much attention to this fact. The needs of each building zone might differ greatly and in order to achieve better indoor environment, different actions might be needed to taken considering the individual characteristics of each zone. In the proposed research the possibilities of evaluating building energy and comfort performance simultaneously taking into account the impact of facade orientation with use of whole building energy simulation tools are investigated through a case study.

Compact vacuum insulation  

DOE Patents (OSTI)

Improved compact insulation panel is provided which is comprised of two adjacent metal sheets spaced close together with a plurality of spherical, or other discretely shaped, glass or ceramic beads optimally positioned between the sheets to provide support and maintain the spacing between the metal sheets when the gases therebetween are evacuated to form a vacuum. These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and variious laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels.

ZIP: Zip-code Insulation Program (for microcomputers). Software  

SciTech Connect

ZIP (the ZIP-code Insulation Program) is a computer program developed to support the DoE Insulation Fact Sheet by providing users with customized estimates of economic levels of residential insulation for any location in the United States, keyed to the first three digits of its ZIP Code. The ZIP program currently calculates economic levels of insulation for attic floors, exterior wood-frame and masonry walls, floors over unheated areas, slab floors, and basement and crawlspace walls. The economic analysis can be conducted for either new or existing houses. Climate parameters are contained in a file on the ZIP diskette and automatically retrieved when the program is run. Regional energy and insulation price data are also retrieved from the ZIP diskette, but these can be overridden to more closely correspond to local prices. ZIP can be run for a single ZIP Code and specified heating and cooling system. It can also be run in a batch mode for any number of consecutive ZIP Codes in order to provide a table of economic insulation levels for use at the state or national level. Software Description: The software is written in the Basic programming language for implementation on the COMPAQ Portable II or compatible machines using MS DOS operating system.

DOE Patents (OSTI)

The manufacture of electrode insulators that are mechanically strong, shock-proof, vacuum tight, and are capable of withstanding gas pressures of many atmospheres under intense neutron bombardment, such as may be needed in an ionization chamber, is described. The ansulator comprises a bolt within a quartz tube, surrounded by a bushing held in place by two quartz rings, and tightened to a pressure of 1,000 pounds per square inch by a nut and washer. Quartz is the superior material to meet these conditions, however, to withstand this pressure the quartz must be fire polished, lapped to form smooth and parallel surfaces, and again fire polished to form an extremely smooth and fracture resistant mating surface.

Multiple layer insulation cover  

DOE Patents (OSTI)

A multiple layer insulation cover for preventing heat loss in, for example, a greenhouse, is disclosed. The cover is comprised of spaced layers of thin foil covered fabric separated from each other by air spaces. The spacing is accomplished by the inflation of spaced air bladders which are integrally formed in the cover and to which the layers of the cover are secured. The bladders are inflated after the cover has been deployed in its intended use to separate the layers of the foil material. The sizes of the material layers are selected to compensate for sagging across the width of the cover so that the desired spacing is uniformly maintained when the cover has been deployed. The bladders are deflated as the cover is stored thereby expediting the storage process and reducing the amount of storage space required.

Correlation effects on topological insulator  

E-Print Network (OSTI)

The strong correlation effects on topological insulator are studied in a two-sublattice system with an onsite single-particle energy difference $\\Delta$ between two sublattices. At $\\Delta=0$, increasing the onsite interaction strength $U$ drives the transition from the quantum spin Hall insulating state to the non-topological antiferromagnetic Mott-insulating (AFMI) state. When $\\Delta$ is larger than a certain value, a topologically trivial band insulator or AFMI at small values of $U$ may change into a quantum anomalous Hall state with antiferromagnetic ordering at intermediate values of $U$. Further increasing $U$ drives the system back into the topologically trivial state of AFMI. The corresponding phenomena is observable in the solid state and cold atom systems. We also propose a scheme to realize and detect these effects in cold atom systems.

Defective insulators in live working on a 550kV compact steel lattice tower  

Science Conference Proceedings (OSTI)

Research was conducted to determine the minimum number of healthy insulator units needed to ensure worker safety in live working on a compact 550 kV steel lattice tower. A large variety of worksite conditions was investigated. Test results confirm the conservative nature of the CIGRE formula for defective insulator units, and modifications to the formula are suggested. The recommended number of healthy units is 12 in a string of 24 units for the case of live work on the compact 550 kV tower, when the Portable Protective Gap (PPG) is used. Adjustment for altitude should be made above 900 m (3,000 ft).

Energy and economic assessment of desiccant cooling systems coupled with single glazed air and hybrid PV/thermal solar collectors for applications in hot and humid climate  

SciTech Connect

This paper presents a detailed analysis of the energy and economic performance of desiccant cooling systems (DEC) equipped with both single glazed standard air and hybrid photovoltaic/thermal (PV/t) collectors for applications in hot and humid climates. The use of 'solar cogeneration' by means of PV/t hybrid collectors enables the simultaneous production of electricity and heat, which can be directly used by desiccant air handling units, thereby making it possible to achieve very energy savings. The present work shows the results of detailed simulations conducted for a set of desiccant cooling systems operating without any heat storage. System performance was investigated through hourly simulations for different systems and load combinations. Three configurations of DEC systems were considered: standard DEC, DEC with an integrated heat pump and DEC with an enthalpy wheel. Two kinds of building occupations were considered: office and lecture room. Moreover, three configurations of solar-assisted air handling units (AHU) equipped with desiccant wheels were considered and compared with standard AHUs, focusing on achievable primary energy savings. The relationship between the solar collector's area and the specific primary energy consumption for different system configurations and building occupation patterns is described. For both occupation patterns, sensitivity analysis on system performance was performed for different solar collector areas. Also, this work presents an economic assessment of the systems. The cost of conserved energy and the payback time were calculated, with and without public incentives for solar cooling systems. It is worth noting that the use of photovoltaics, and thus the exploitation of related available incentives in many European countries, could positively influence the spread of solar air cooling technologies (SAC). An outcome of this work is that SAC systems equipped with PV/t collectors are shown to have better performance in terms of primary energy saving than conventional systems fed by vapour compression chillers and coupled with PV cells. All SAC systems present good figures for primary energy consumption. The best performances are seen in systems with integrated heat pumps and small solar collector areas. The economics of these SAC systems at current equipment costs and energy prices are acceptable. They become more interesting in the case of public incentives of up to 30% of the investment cost (Simple Payback Time from 5 to 10 years) and doubled energy prices. (author)

Environmental design using dynamic insulation  

SciTech Connect

In conventional airtight buildings, the architect has considerable freedom to decide how much the external environment will influence the internal heating, cooling, and ventilation loads. The services engineer provides the plant and equipment required to deal with these loads. This division of labor could lead to undesirable consequences in the case of dynamic insulation, a form of air permeable construction where bulk air flow through the building envelope may be used to either enhance or restrict the conductive heat and mass diffusion fluxes. Small changes in temperature (indoor and out) and wind speed and direction will influence the behavior of a dynamically insulated envelope since the internal and external environments are much more intimately coupled. Buildings employing dynamic insulation thus require good environmental design principles to be applied. The objective of this paper is to lay down rigorous principles that will form the basis of guidelines to architects and building services engineers on how to take account of the ever changing external environment when designing durable and comfortable buildings employing dynamic insulation.

Vacuum-insulated catalytic converter  

DOE Patents (OSTI)

A catalytic converter has an inner canister that contains catalyst-coated substrates and an outer canister that encloses an annular, variable vacuum insulation chamber surrounding the inner canister. An annular tank containing phase-change material for heat storage and release is positioned in the variable vacuum insulation chamber a distance spaced part from the inner canister. A reversible hydrogen getter in the variable vacuum insulation chamber, preferably on a surface of the heat storage tank, releases hydrogen into the variable vacuum insulation chamber to conduct heat when the phase-change material is hot and absorbs the hydrogen to limit heat transfer to radiation when the phase-change material is cool. A porous zeolite trap in the inner canister absorbs and retains hydrocarbons from the exhaust gases when the catalyst-coated substrates and zeolite trap are cold and releases the hydrocarbons for reaction on the catalyst-coated substrate when the zeolite trap and catalyst-coated substrate get hot.

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

Aerogel Insulation Aerogel Insulation New and Underutilized Technology: Aerogel Insulation October 8, 2013 - 2:54pm Addthis The following information outlines key deployment considerations for aerogel insulation within the Federal sector. Benefits Aerogel insulation products displace current insulation materials. The thermal conductivity of aerogel is very low, allowing it to retain insulation properties at a much thinner thickness. Application Aerogel insulation is appropriate for deployment across piping, ducts, and within most building categories. It should be considered in building design, construction, or major renovation. Key Factors for Deployment Aerogel insulations are more expensive than typical insulations. However, they are ideal for special applications, such as translucent wall panels.

Impact of Thermally Insulated Floors  

E-Print Network (OSTI)

Presently in Kuwait the code of practice for energy conservation in the air conditioned buildings implemented by the Ministry of Electricity and Water (MEW) which has been in effect since 1983 has no consideration taken for thermally insulating the floors of residential and commercial buildings with unconditioned basements. As a part of a comprehensive research program conducted by the Building and Energy Technologies Department of Kuwait Institute for Scientific Research for revision of the code this paper analyzes the effect of using un-insulated floors on the peak cooling demand and energy consumption of a middle income residential private villa and a onebedroom multi-story apartment building in Kuwait. These floors typically separate air-conditioned spaces with ambient environment or un-conditioned spaces. This was done using the ESP-r, a building's energy simulation program, in conjunction with typical meteorological year for Kuwait. The study compared such typical floors with three types of insulated floors. It was found that using an R- 10 floors in multi-story apartment buildings greatly reduce both the peak cooling demand as well as the energy consumption by about 15%, whereas only minimal savings (about 4%) were detected in the case of the residential villas.

Switchable window modeling. Task 12: Building energy analysis and design tools for solar applications, Subtask A.1: High-performance glazing  

SciTech Connect

This document presents the work conducted as part of Subtask A.1, High-Performance Glazing, of Task 12 of the IEA Solar Heating and Cooling Program. At the start of the task, the participants agreed that chromogenic technology (switchable glazing) held considerable promise, and that algorithms to accurately model their dynamic behavior were needed. The purpose of this subtask was to develop algorithms that could be incorporated into building energy analysis programs for predicting the thermal and optical performance of switchable windows. The work entailed a review of current techniques for modelling switchable glazing in windows and switchable windows in buildings and methods for improving upon existing modeling approaches. The proposed approaches correct some of the shortcomings in the existing techniques, and could be adapted for use in other similar programs. The proposed approaches generally provide more detailed calculations needed for evaluating the short-term (hourly and daily) impact of switchable windows on the energy and daylighting performance of a building. Examples of the proposed algorithms are included.

Householders Perceptions of Insulation Adequacy and Drafts in the Home in 2001  

E-Print Network (OSTI)

In order to improve the estimation of end-use heating consumption, the Energy Information Administration's (EIA), 2001 Residential Energy Consumption Survey (RECS), for the first time, asked respondents to judge how drafty they perceived their homes to be as a measure of insulation quality. The analysis of the 2001 RECS data shows that householders in newlyconstructed homes perceived their homes to be better insulated and less drafty than do householders in older homes. Single-family homes are perceived to be better insulated and less drafty than are apartments in buildings with two to four units. Cross-variable comparisons also provide the associations between the level of insulation and winter drafts in the homes with household characteristics and location of the home.

Degradation of Structural Alloys Under Thermal Insulation  

E-Print Network (OSTI)

Wet thermal insulation may actively degrade steel and stainless steel structures by general corrosion or stress-corrosion cracking. Two different mechanisms of water ingress into insulation are discussed; flooding from external sources, and migration from condensation of atmospheric moisture. The general corrosion rate of steels under insulation is predictable (within a broad scatter band) on the basis of temperature and oxygen content. This relationship is presented graphically based on plant case histories. Rainwater, washwater and the insulation itself are compared as potential sources of chloride to promote external SCC of stainless steels. Preventative measures will be discussed.

Fully synthetic taped insulation cables  

DOE Patents (OSTI)

The present invention is a cable which, although constructed from inexpensive polyolefin tapes and using typical impregnating oils, furnishes high voltage capability up to 765 kV, and has such excellent dielectric characteristics and heat transfer properties that it is capable of operation at capacities equal to or higher than presently available cables at a given voltage. This is accomplished by using polyethylene, polybutene or polypropylene insulating tape which has been specially processed to attain properties which are not generally found in these materials, but are required for their use in impregnated electrical cables. Chief among these properties is compatibility with impregnating oil.

Free-formed insulated concentrating solar collector. Final report  

DOE Green Energy (OSTI)

A free-formed, insulated solar concentrating-collector was designed, built, and tested. The design utilizes new concepts to achieve simplicity, low cost, high efficiency, and long service life. Three concepts were utilized to meet these goals: First, the concentrating reflector is free-formed by hand from a thin steel sheet. Second, a transparent cover is placed over the concentrator and insulation is placed on the back and ends reduce heat losses and protect the reflecting surface from attack by rain and dust. Third, a highly-reflective aluminum film, protected by bonding between two thin sheets of uv stabilized polyester, is fastened to the steel substrate by peelable adhesive. The material cost of the unit without sun seeking electronics and drive motor is about $6.75 per square foot of sun capturing area. Sun following equipment adds to the cost, however, in units of about 100 square feet sun following equipment contributes about $2.00 per square foot. Labor costs are estimated to be approximately $3.00 per square foot for a $5.00 per hour labor rate for a trained crew. On a do-it-yourself basis a 100 square foot unit would cost about $875. Tests of the prototype collector performed by a certified solar test laboratory were made and the results compared with similar tests of a commercial unit. These tests indicate that the efficiency of the prototype is higher than the commercial unit at outlet temperatures below 160/sup 0/F and comparable with the commercial unit at the boiling point of water.

Modeled and metered energy savings from exterior wall insulation  

SciTech Connect

Millions of single-family masonry (block) houses with slab foundations exist in the southern United States. In fact, approximately 50% of Florida`s six million residences are of concrete block construction. The block walls in these homes are usually uninsulated, and the technology for retrofitting wall insulation is not well developed. Two field tests were performed--one near Phoenix, Arizona and one in Cocoa, Florida--to measure the air-conditioning energy savings and demand reduction impact of applying an exterior insulation and finish system (EEFS) to the exterior of the block wall, and gain practical experience with retrofit application techniques and costs. One field test used a {open_quotes}site-fabricated{close_quotes} insulation system, while the other field test used a commercially available system. The field tests measured a savings of 9% in Arizona and less savings in Florida, and emphasized the impact indoor temperature settings have on cooling energy savings: exterior wall insulation on block homes will produce energy savings in Florida houses only if a low cooling thermostat setting is desirable. The field tests also highlighted an improved comfort benefit from the retrofit - namely, elimination of overheating in rooms with south and west exposures. The DOE-2. ID program was used to analyze the energy savings (air-conditioning and heating) and electric demand impact of applying an EIFS. Air-conditioning energy savings were estimated to be in the range of 8% to 10% in many southern U.S. regions. A 12% savings was predicted for Phoenix, Arizona and a savings of 1% to 4% was predicted for seacoast regions, particularly in Florida. These predictions were in good agreement with the measured values. Peak hour cooling energy savings were predicted to be more uniform throughout the country, generally in the range of %8 to %12.

ITER Central Solenoid Coil Insulation Qualification  

Science Conference Proceedings (OSTI)

An insulation system for ITER Central Solenoid must have sufficiently high electrical and structural strength. Design efforts to bring stresses in the turn and layer insulation within allowables failed. It turned out to be impossible to eliminate high local tensile stresses in the winding pack. When high local stresses can not be designed out, the qualification procedure requires verification of the acceptable structural and electrical strength by testing. We built two 4x4 arrays of the conductor jacket with two options of the CS insulation and subjected the arrays to 1.2 million compressive cycles at 60 MPa and at 76 K. Such conditions simulated stresses in the CS insulation. We performed voltage withstand tests and after end of cycling we measured the breakdown voltages between in the arrays. After that we dissectioned the arrays and studied micro cracks in the insulation. We report details of the specimens preparation, test procedures and test results.

Welcome to the Efficient Windows Collaborative  

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

Glass Glass Vacuum-insulated Glass Vacuum-insulated glazing units are made up of 2 panes of glass with a very small air space. The air space contains spacers which help maintain the separation between the panes. Most of the emerging glass technologies are available or nearly on the market. These include insulation-filled and evacuated glazings to improve heat transfer by lowering U-factors. Evacuated Windows The most thermally efficient gas fill would be no gas at all-a vacuum. The window industry is pursuing the development of vacuum-insulated glass (VIG) for use in window units in which the space between the panes is evacuated. If the vacuum pressure is low enough, there would be no conductive or convective heat exchange between the panes of glass, thus lowering the U-factor. A vacuum glazing must have a good low-E coating to

Topological Insulator Nanowires and Nanoribbons  

SciTech Connect

Recent theoretical calculations and photoemission spectroscopy measurements on the bulk Bi{sub 2}Se{sub 3} material show that it is a three-dimensional topological insulator possessing conductive surface states with nondegenerate spins, attractive for dissipationless electronics and spintronics applications. Nanoscale topological insulator materials have a large surface-to-volume ratio that can manifest the conductive surface states and are promising candidates for devices. Here we report the synthesis and characterization of high quality single crystalline Bi{sub 2}Se{sub 3} nanomaterials with a variety of morphologies. The synthesis of Bi{sub 2}Se{sub 3} nanowires and nanoribbons employs Au-catalyzed vapor-liquid-solid (VLS) mechanism. Nanowires, which exhibit rough surfaces, are formed by stacking nanoplatelets along the axial direction of the wires. Nanoribbons are grown along [11-20] direction with a rectangular crosssection and have diverse morphologies, including quasi-one-dimensional, sheetlike, zigzag and sawtooth shapes. Scanning tunneling microscopy (STM) studies on nanoribbons show atomically smooth surfaces with {approx}1 nm step edges, indicating single Se-Bi-Se-Bi-Se quintuple layers. STM measurements reveal a honeycomb atomic lattice, suggesting that the STM tip couples not only to the top Se atomic layer, but also to the Bi atomic layer underneath, which opens up the possibility to investigate the contribution of different atomic orbitals to the topological surface states. Transport measurements of a single nanoribbon device (four terminal resistance and Hall resistance) show great promise for nanoribbons as candidates to study topological surface states.

Labeling and advertising of home insulation  

SciTech Connect

This staff report, prepared by the F.T.C.'s Bureau of Consumer Protection for Commission review, includes recommendations as to the final form of a trade regulation rule relating to the labeling and advertising of home insulation. Because of marketing abuses which accompanied the rising demand for home insulation, there has been broad support for a rule requiring information disclosures to help purchasers of home insulation to make an informed decision. The Commission, to provide such rule as quickly as possible, undertook its rulemaking proceeding under its new expedited rulemaking procedure. The rule was proposed on November 18, 1977, and, following a two-month period for written comments, four weeks of hearings were held in Washington, D.C. in February 1978. The record, contributed to by a variety of interests, shows that consumers do not know how to shop for home insulation. The staff-recommended rule, among other things, would require that insulation be tested and R-values (a measure of insulation's ability to retain heat) disclosed on labels and in advertising. To facilitate comparison shopping, the industry would also be required to furnish consumers with fact sheets describing, on a product-to-product basis, factors that can reduce the R-value of insulation.

KSI's Cross Insulated Core Transformer Technology  

Science Conference Proceedings (OSTI)

Cross Insulated Core Transformer (CCT) technology improves on Insulated Core Transformer (ICT) implementations. ICT systems are widely used in very high voltage, high power, power supply systems. In an ICT transformer ferrite core sections are insulated from their neighboring ferrite cores. Flux leakage is present at each of these insulated gaps. The flux loss is raised to the power of stages in the ICT design causing output voltage efficiency to taper off with increasing stages. KSI's CCT technology utilizes a patented technique to compensate the flux loss at each stage of an ICT system. Design equations to calculate the flux compensation capacitor value are presented. CCT provides corona free operation of the HV stack. KSI's CCT based High Voltage power supply systems offer high efficiency operation, high frequency switching, low stored energy and smaller size over comparable ICT systems.

Thermal conductivity of thermal-battery insulations  

DOE Green Energy (OSTI)

The thermal conductivities of a variety of insulating materials used in thermal batteries were measured in atmospheres of argon and helium using several techniques. (Helium was used to simulate the hydrogen atmosphere that results when a Li(Si)/FeS{sub 2} thermal battery ages.) The guarded-hot-plate method was used with the Min-K insulation because of its extremely low thermal conductivity. For comparison purposes, the thermal conductivity of the Min-K insulating board was also measured using the hot-probe method. The thermal-comparator method was used for the rigid Fiberfrax board and Fiberfrax paper. The thermal conductivity of the paper was measured under several levels of compression to simulate the conditions of the insulating wrap used on the stack in a thermal battery. The results of preliminary thermal-characterization tests with several silica aerogel materials are also presented.

Metal-insulator transition in holography  

E-Print Network (OSTI)

We exhibit an interaction-driven metal-insulator quantum phase transition in a holographic model. Use of a helical lattice enables us to break translation invariance while preserving homogeneity. The metallic phase is characterized by a sharp Drude peak and a d.c. resistivity that increases with temperature. In the insulating phase the Drude spectral weight is transferred into a `mid-infrared' peak and to energy scales of order the chemical potential. The d.c. resistivity now decreases with temperature. In the metallic phase, operators breaking translation invariance are irrelevant at low energy scales. In the insulating phase, translation symmetry breaking effects are present at low energies. We find the near horizon extremal geometry that captures the insulating physics.

Cost-Energy Dynamics of Thermal Insulation: Potential Energy Savings and Policy Recommendations  

E-Print Network (OSTI)

This paper looks at extra insulation for saving energy from the viewpoint of a decision maker. Public and private decisions are distinguished. Profitability and process analyses are combined to obtain a simple trade-off relationship between the extra cost and extra energy saving. Due to higher costs of energy at present and in the foreseeable future, good opportunities exist to retrofit existing thermal envelopes with extra insulation. Potential costs and savings in the residential, commercial and manufacturing sectors are assessed. A hypothetical $10 billion insulation budget is determined to save 0.5 quad/yr of energy for the next 10 to 15 years, resulting in conservation energy costing less than $2/MMBtu. It is argued that public subsidies to energy conservation and energy supply technologies should be weighed so that the worth of each unit of resultant energy at the point of use is the same.

Design Tool for Cryogenic Thermal Insulation Systems  

Science Conference Proceedings (OSTI)

Thermal isolation of low-temperature systems from ambient environments is a constant issue faced by practitioners of cryogenics. For energy-efficient systems and processes to be realized, thermal insulation must be considered as an integrated system, not merely an add-on element. A design tool to determine the performance of insulation systems for comparative trade-off studies of different available material options was developed. The approach is to apply thermal analysis to standard shapes (plane walls, cylinders, spheres) that are relatively simple to characterize with a one-dimensional analytical or numerical model. The user describes the system hot and cold boundary geometry and the operating environment. Basic outputs such as heat load and temperature profiles are determined. The user can select from a built-in insulation material database or input user defined materials. Existing information has been combined with the new experimental thermal conductivity data produced by the Cryogenics Test Laboratory for cryogenic and vacuum environments, including high vacuum, soft vacuum, and no vacuum. Materials in the design tool include multilayer insulation, aerogel blankets, aerogel bulk-fill, foams, powders, composites, and other insulation system constructions. A comparison of the design tool to a specific composite thermal insulation system is given.

Topological Insulators and Superconductors from String Theory  

E-Print Network (OSTI)

Topological insulators and superconductors in different spatial dimensions and with different discrete symmetries have been fully classified recently, revealing a periodic structure for the pattern of possible types of topological insulators and supercondutors, both in terms of spatial dimensions and in terms of symmetry classes. It was proposed that K-theory is behind the periodicity. On the other hand, D-branes, a solitonic object in string theory, are also known to be classified by K-theory. In this paper, by inspecting low-energy effective field theories realized by two parallel D-branes, we establish a one-to-one correspondence between the K-theory classification of topological insulators/superconductors and D-brane charges. In addition, the string theory realization of topological insulators and superconductors comes naturally with gauge interactions, and the Wess-Zumino term of the D-branes gives rise to a gauge field theory of topological nature, such as ones with the Chern-Simons term or the $\\theta$-term in various dimensions. This sheds light on topological insulators and superconductors beyond non-interacting systems, and the underlying topological field theory description thereof. In particular, our string theory realization includes the honeycomb lattice Kitaev model in two spatial dimensions, and its higher-dimensional extensions. Increasing the number of D-branes naturally leads to a realization of topological insulators and superconductors in terms of holography (AdS/CFT).

Zip 2.0 (the ZIP Code Insulation Program) provides users with customized estimates of economic levels of residential insulation for any location in the United States, keyed to the first three digits of its Zip Code. It currently calculates economic levels of insulation for attic floors, exterior wood-frame and masonry walls, floors over unheated areas, slab floors, and basement and crawlspace walls, ductwork in unconditioned spaces, and water heaters. Climate parameters are contained in a file on the ZIP diskette and automatically retrieved when the program is run. The user must designate the type of heating and cooling equipment present in the house. Default energy and insulation price data are also retrieved from the ZIP diskette, but these can be overridden to correspond to local prices. A comprehensive report is displayed with the economic R-values, advisory material, and a list of the user's input assumptions. An economic analysis can be conducted for either new or existing houses. The program can be run for a single Zip Code and specified heating and cooling system. It can also be run in a batch mode for any number of consecutive Zip Codes in order to provide a table of economic insulation levels for use at the state or national level.

Phase II developed a focus around two specific IG design classes previously presented in Phase I of this project. The typical box spacer and thermoplastic spacer design including their Failure Modes and Effect Analysis (FMEA) and Fault Tree diagrams were chosen to address two currently used IG design options with varying components and failure modes. The system failures occur due to failures of components or their interfaces. Efforts to begin quantifying the durability issues focused on the development and delivery of an included computer based IG durability simulation program. The focus/effort to deliver the foundation for a comprehensive IG durability simulation tool is necessary to address advancements needed to meet current and future building envelope energy performance goals. This need is based upon the current lack of IG field failure data and the lengthy field observation time necessary for this data collection. Ultimately, the simulation program is intended to be used by designers throughout the current and future industry supply chain. Its use is intended to advance IG durability as expectations grow around energy conservation and with the growth of embedded technologies as required to meet energy needs. In addition the tool has the immediate benefit of providing insight for research and improvement prioritization. Included in the simulation model presentation are elements and/or methods to address IG materials, design, process, quality, induced stress (environmental and other factors), validation, etc. In addition, acquired data is presented in support of project and model assumptions. Finally, current and suggested testing protocol and procedure for future model validation and IG physical testing are discussed.

NOTES ON THERMAL PROPERTIES AND HEAT TRANSFER OF SYNTACTIC FOAM SUBSEA INSULATION  

E-Print Network (OSTI)

1. The properties that make syntactic foam an efficient buoyancy material also make it a good subsea thermal insulator: low density, high strength, and resistance to water penetration. The hollow spherical fillers in the foam contain air and prevent its compres-sion by hydrostatic force. The air in turn acts as a very effective insulator, slowing heat transfer as long as structural integrity is maintained. 2. Heat transfer textbooks list three modes of heat transfer: conduction, convection, and radiation. Radiation is seldom a factor in wet subsea insulation, and convection plays a role only when water is free to circulate, a condition normally avoided. Therefore, this paper focuses on conduction as the principal way in which heat travels through syntactic foam insulation. 3. A glossary of heat transfer properties is given on Page 4. The following definitions apply to the terms we will be using most frequently: Density: Mass per unit volume is symbolized by the Greek letter rho (_); it is usually numerically equivalent to weight per unit volume, but caution is required to make sure the correct values are always used. Thermal Conductivity: The rate at which heat is conducted through the material in question. The higher the conductivity (k-value), the more easily heat will be transmitted from the hot to the

The Insulation Energy Appraisal Assessing the True Value of Insulated System  

E-Print Network (OSTI)

Insulation remains a seriously under-utilized technology in the manufacturing and industrial sectors of the economy even though its role in energy efficiency and environmental preservation is clear. The objective of the presentation is to educate the audience about the enormous savings potential of insulation in terms of reduced energy costs, improved process control, reduced greenhouse gas emissions, noise control and personnel protection. In addition, the presentation will introduce the audience to a new energy management tool designed to help facility/energy managers understand the true dollar and performance value of insulation- the Insulation Energy Appraisal Program. The program has achieved tremendous success with all classes sold out to date. The presentation will highlight various components of the intensive 2-day training program which teaches an appraiser how to: evaluate the thermal performance of insulated versus uninsulated piping and equipment; translate Btu losses into actual dollars; and calculate greenhouse gas emissions.

ZIP. Economic Insulation Levels for Houses  

SciTech Connect

ZIP was developed to support the calculations and database used to estimate the economic levels of insulation published in the U.S. Department of Energy`s Insulation Fact Sheet. The program allows the user to estimate economic levels of insulation for attics, exterior walls, floors over unheated areas, slab floors, and basement and crawlspace walls for new and existing houses in any 3-digit zip code location in the U.S., based on local climate data, local prices for energy and insulation, and the type and estimated efficiency of its heating and cooling system. ZIP recognizes five different heating systems: natural gas, oil furnaces, electric furnaces, electric baseboard, and electric heat pump and two cooling systems: central and window electric air conditioners. An evaporative cooling system can also be specified, but this is not treated as a true air-conditioning system. In addition, the user can specify the approximate operating efficiency of the heating and cooling systems (low, medium, high, or very high). ZIP can be run for a single zip code and specified heating and cooling system or in a batch mode for any number of consecutive zip codes to provide a table of economic insulation levels for use at the state or national level.

Tool for cutting insulation from electrical cables  

DOE Patents (OSTI)

This invention is an efficient hand tool for precisely slitting the sheath of insulation on an electrical cable--e.g., a cable two inches in diameter--in a manner facilitating subsequent peeling or stripping of the insulation. The tool includes a rigid frame which is slidably fitted on an end section of the cable. The frame carries a rigidly affixed handle and an opposed, elongated blade-and-handle assembly. The blade-and-handle assembly is pivotally supported by a bracket which is slidably mounted on the frame for movement toward and away from the cable, thus providing an adjustment for the depth of cut. The blade-and-handle assembly is mountable to the bracket in two pivotable positions. With the assembly mounted in the first position, the tool is turned about the cable to slit the insulation circumferentially. With the assembly mounted in the second position, the tool is drawn along the cable to slit the insulation axially. When cut both circumferentially and axially, the insulation can easily be peeled from the cable.

Is graphene in vacuum an insulator?  

E-Print Network (OSTI)

We present evidence, from Lattice Monte Carlo simulations of the phase diagram of graphene as a function of the Coulomb coupling between quasiparticles, that graphene in vacuum is likely to be an insulator. We find a semimetal-insulator transition at $\\alpha_g^\\text{crit} = 1.11 \\pm 0.06$, where $\\alpha_g^{} \\simeq 2.16$ in vacuum, and $\\alpha_g^{} \\simeq 0.79$ on a SiO$_2^{}$ substrate. Our analysis uses the logarithmic derivative of the order parameter, supplemented by an equation of state.

Multilayer insulation blanket, fabricating apparatus and method  

DOE Patents (OSTI)

An improved multilayer insulation blanket for insulating cryogenic structures operating at very low temperatures is disclosed. An apparatus and method for fabricating the improved blanket are also disclosed. In the improved blanket, each successive layer of insulating material is greater in length and width than the preceding layer so as to accommodate thermal contraction of the layers closest to the cryogenic structure. The fabricating apparatus has a rotatable cylindrical mandrel having an outer surface of fixed radius that is substantially arcuate, preferably convex, in cross-section. The method of fabricating the improved blanket comprises (a) winding a continuous sheet of thermally reflective material around the circumference of the mandrel to form multiple layers, (b) binding the layers along two lines substantially parallel to the edges of the circumference of the mandrel, (c) cutting the layers along a line parallel to the axle of the mandrel, and (d) removing the bound layers from the mandrel.

Test Report: Cost Effective Foundation Insulation  

SciTech Connect

A field experiment was conducted to demonstrate and quantify the thermal effectiveness of rigid insulation board when installed on the exterior of a buried concrete foundation wall. A heated, insulated box was constructed along one wall of an existing, unheated building to simulate the living space of a home. The crawl space beneath the living space was divided into two sections. One featured external foundation insulation, while the other side had none. 36 temperature and heat flux sensors were installed at predetermined locations to measure the temperature profile and heat flow out of the living space. The temperature profile through the foundation was then used to calculate the total heat flow out of the foundation for both cases. This experiment showed that a significant energy savings is available with exterior foundation insulation. Over the course of 3 months, the heat-loss differential between the insulated and non-insulated foundations was 4.95 kilowatt-hours per lineal foot of foundation wall, for a ratio of 3:1. For a 2200 sq. ft home with a foundation perimeter 200 ft. long, this would amount to a savings of 990 kW-hrs in just 3 months, or 330 kW-hrs per month. Extrapolating to an 8-month heating year, we would expect to save over 2640 kW-hrs per year for such a home. The savings for a basement foundation, rather than a crawlspace, would be approach twice that amount, nearing 5280 kW-hr per year. Because these data were not collected during the coldest months of the year, they are conservative, and greater savings may be expected during colder periods.

ZIP - The ZIP-Code Insulation Program (version 1. 0) economic insulation levels for new and existing houses by three-digit ZIP code: Users guide and reference manual  

SciTech Connect

ZIP 1.0 (the ZIP-code Insulation program) is a computer program developed to support the DOE Insulation Fact Sheet by providing users with customized estimates of economic levels of residential insulation. These estimates can be made for any location in the United States by entering the first three digits of its ZIP Code. The program and supporting files are contained on a single 5.25-in. diskette for use with microcomputers having an MS-DOS operating system capability. The ZIP program currently calculates economic levels of insulation for attic floors, exterior wood-frame and masonry walls, floor over unheated areas, slab floors, and basement and crawlspace wells. The economic analysis can be conducted for either new or existing houses. Climate parameters are contained in a file on the ZIP diskette and automatically retrieved when the program is run. Regional energy and insulation price data are also retrieved from the ZIP diskette, but these can be overridden to more closely correspond to local prices. Zip can be run for a single ZIP Code and specified heating and cooling system. It can also be run in a ''batch'' mode for any number of consecutive ZIP Codes in order to provide a table of economic insulation levels for use at the state or national level. 4 tabs.

When wall insulation doesn`t save  

Science Conference Proceedings (OSTI)

A recent study in Florida concluded that while wall insulation clearly saves heating energy, it is less effective at saving cooling energy. The study focused on concrete block houses on slab foundations, and determined that whether insulation saves cooling energy depends significantly on the interior thermostat setpoint, the lower the thermostat below outside temperature, the more likely wall installation was to save energy. This article describes the design of the study and compares it to other studies. Results in their entirety are described. 1 fig.

Development and Testing of Insulated Drill Pipe  

DOE Green Energy (OSTI)

This project has comprised design, analysis, laboratory testing, and field testing of insulated drill pipe (IDP). This paper will briefly describe the earlier work, but will focus on results from the recently-completed field test in a geothermal well. Field test results are consistent with earlier analyses and laboratory tests, all of which support the conclusion that insulated drill pipe can have a very significant effect on circulating fluid temperatures. This will enable the use of downhole motors and steering tools in hot wells, and will reduce corrosion, deterioration of drilling fluids, and heat-induced failures in other downhole components.

Process for forming transparent aerogel insulating arrays  

DOE Patents (OSTI)

An improved supercritical drying process for forming transparent silica aerogel arrays is described. The process is of the type utilizing the steps of hydrolyzing and condensing aloxides to form alcogels. A subsequent step removes the alcohol to form aerogels. The improvement includes the additional step, after alcogels are formed, of substituting a solvent, such as CO/sub 2/, for the alcohol in the alcogels, the solvent having a critical temperature less than the critical temperature of the alcohol. The resulting gels are dried at a supercritical temperature for the selected solvent, such as CO/sub 2/, to thereby provide a transparent aerogel array within a substantially reduced (days-to-hours) time period. The supercritical drying occurs at about 40/sup 0/C instead of at about 270/sup 0/C. The improved process provides increased yields of large scale, structurally sound arrays. The transparent aerogel array, formed in sheets or slabs, as made in accordance with the improved process, can replace the air gap within a double glazed window, for example, to provide a substantial reduction in heat transfer. The thus formed transparent aerogel arrays may also be utilized, for example, in windows of refrigerators and ovens, or in the walls and doors thereof or as the active material in detectors for analyzing high energy elementary particles or cosmic rays.

Design method to determine the optimal distribution and amount of insulation for in-ground heat storage tanks  

DOE Green Energy (OSTI)

The seasonal sensible heat storage model developed by F.C. Hooper and C.R. Attwater is modified to describe the thermal behaviour of the soil regime surrounding cylindrical, in-ground, heat storage tanks with optimally distributed insulation. The model assumes steady-state heat transfer, and the surrounding soil is considered to be homogeneous and isotropic. Changes in soil thermal properties due to moisture migration, whether driven by thermal or hydrostatic gradients, are assumed negligible. The optimal distribution is determined using the method of Lagrange multipliers. It is shown that the marginal cost per unit of energy lost and per unit of tank surface area must be the same at all points on the surface of the tank as the condition for minimum total heat loss with a given total investment in insulation. This condition appears to apply for all axi-symmetric in-ground tank geometries. For a given volume of insulation, the incremental increase in storage efficiency with an optimal redistribution of the insulation is a function of tank geometry. The problem of determining the optimal total investment in insulation for a given marginal cost of fuel is described and a method of solution is outlined.

Experience with 113 Retrofit Insulation Surveys  

E-Print Network (OSTI)

We have surveyed 113 plants for thirteen clients. The results of 21 recent surveys at today's average fuel price, show an average project scope generation of $151,000 while saving about 5MMBTU/hour with a 72% DCF rate of return. The size of the retrofit project generated, or scope, is of course sensitive to the fuel price. This is an important consideration because of the variability of fuel price. A study of the effect of fuel price on project scope generation and on return has been made using sophisticated computer programs designed for this purpose. These results indicate that scope generation may vary from $50,000 for $3.00 fuel up to $80,000 for $6.00 fuel. When this happens, the project return will increase from 100% up to 165% per year. The main problem that we have found with retrofit insulation surveys is the processing of detail in existing plants. The solution is the preparation or selection of the right system for approaching the problem utilizing computer programs. The time required to generate systematic approaches to insulation surveys and the generation of retrofit projects are sizable. The continued heat losses while studying the project are also significant. Thus, the heat losses suffered while deciding how to insulate can be sufficient to pay for an insulation survey.

Vacuum Insulator Development for the Dielectric Wall Accelerator  

Science Conference Proceedings (OSTI)

At Lawrence Livermore National Laboratory, we are developing a new type of accelerator, known as a Dielectric Wall Accelerator, in which compact pulse forming lines directly apply an accelerating field to the beam through an insulating vacuum boundary. The electrical strength of this insulator may define the maximum gradient achievable in these machines. To increase the system gradient, we are using 'High Gradient Insulators' composed of alternating layers of dielectric and metal for the vacuum insulator. In this paper, we present our recent results from experiment and simulation, including the first test of a High Gradient Insulator in a functioning Dielectric Wall Accelerator cell.

Emerging Weak Localization Effects on Topological Insulator-Insulating Ferromagnet (Bi_2Se_3-EuS) Interface  

E-Print Network (OSTI)

Thin films of topological insulator Bi_2Se_3 were deposited directly on insulating ferromagnetic EuS. Unusual negative magnetoresistance was observed near the zero field below the Curie temperature (T_C), resembling the weak localization effect; whereas the usual positive magnetoresistance was recovered above T_C. Such negative magnetoresistance was only observed for Bi_2Se_3 layers thinner than t~4nm, when its top and bottom surfaces are coupled. These results provide evidence for a proximity effect between a topological insulator and an insulating ferromagnet, laying the foundation for future realization of the half-integer quantized anomalous Hall effect in three-dimensional topological insulators.

Nuclear reactor insulation and preheat system  

DOE Patents (OSTI)

An insulation and preheat system for preselected components of a fluid cooled nuclear reactor. A gas tight barrier or compartment of thermal insulation surrounds the selected components and includes devices to heat the internal atmosphere of the compartment. An external surface of the compartment or enclosure is cooled, such as by a circulating fluid. The heating devices provide for preheating of the components, as well as maintenance of a temperature sufficient to ensure that the reactor coolant fluid will not solidify during shutdown. The external cooling limits the heat transferred to other plant structures, such as supporting concrete and steel. The barrier is spaced far enough from the surrounded components so as to allow access for remote or manual inspection, maintenance, and repair.

Edge Excitations in Fractional Chern Insulators  

E-Print Network (OSTI)

Recent theoretical works have demonstrated the realization of fractional quantum anomalous Hall states (also called fractional Chern insulators) in topological flat band lattice models without an external magnetic field. Such newly proposed lattice systems play a vital role to obtain a large class of fractional topological phases. Here we report the exact numerical studies of edge excitations for such systems in a disk geometry loaded with hard-core bosons, which will serve as a more viable experimental probe for such topologically ordered states. We find convincing numerical evidence of a series of edge excitations characterized by the chiral Luttinger liquid theory for the bosonic fractional Chern insulators in both the honeycomb disk Haldane model and the kagom\\'{e}-lattice disk model. We further verify these current-carrying chiral edge states by inserting a central flux to test their compressibility.

Repulsive Casimir Effect with Chern insulators  

E-Print Network (OSTI)

We theoretically predict that the Casimir force in vacuum between two Chern insulator plates can be repulsive (attractive) at long distances whenever the sign of the Chern numbers characterizing the two plates are opposite (equal) and can be further tuned to attraction by electrostatic doping. We calculate and take into account the full optical response of the plates and argue that such repulsion is a general phenomena for these systems as it relies on the quantized zero frequency Hall conductivity. We discuss the possibility of achieving repulsion with thin films of Cr-doped (Bi,Sb)$_2$Te$_3$, that were recently discovered to be Chern insulators with quantized Hall conductivity and point towards multi-orbital systems as a route to realize this novel phenomenon.

Humidity effects on wire insulation breakdown strength.  

SciTech Connect

Methods for the testing of the dielectric breakdown strength of insulation on metal wires under variable humidity conditions were developed. Two methods, an ASTM method and the twisted pair method, were compared to determine if the twisted pair method could be used for determination of breakdown strength under variable humidity conditions. It was concluded that, although there were small differences in outcomes between the two testing methods, the non-standard method (twisted pair) would be appropriate to use for further testing of the effects of humidity on breakdown performance. The dielectric breakdown strength of 34G copper wire insulated with double layer Poly-Thermaleze/Polyamide-imide insulation was measured using the twisted pair method under a variety of relative humidity (RH) conditions and exposure times. Humidity at 50% RH and below was not found to affect the dielectric breakdown strength. At 80% RH the dielectric breakdown strength was significantly diminished. No effect for exposure time up to 140 hours was observed at 50 or 80%RH.

Lightning overvoltage protection of the paddock 362-145 kV Gas-Insulated Substation  

SciTech Connect

Backflashovers close to the Paddiock 362-145 kV Gas-Insulated Substation (GIS) have been analyzed with the Electro-Magnetic Transient Program (EMTP) using a frequency dependent multi-conductor system. The severity of the lightning stroke currents were derived based on recent recordings in the eastern United States. Impacts of corona attenuation and distortion were accounted for using a shunt linear model approach. Turn-up effects of both line insulator flashover voltages and surge arrester protective characteristics were represented based on manufacturer's volt-time curves. Wave shaping effects of substation capacitances (ie., PT's transformers, CCPD's) were also modeled. Results show the importance of various modeling details in determining the overvoltages inside the GIS due to close backflashovers, which are caused by lightning strokes with varying intensity. These results are aimed at better evaluation of lightning protection requirements for GIS protected by metal-oxide surge arresters.

Development of a Leave-in-Place Slab Edge Insulating Form System  

DOE Green Energy (OSTI)

Concrete slabs represent the primary foundation type in residential buildings in the fast-growing markets throughout the southern and southwestern United States. Nearly 75% of the 2005 U.S. population growth occurred in these southern tier states. Virtually all of these homes have uninsulated slab perimeters that transfer a small, but steady, flow of heat from conditioned space to outdoors during the heating season. It is estimated that new home foundations constructed each year add 0.016 quads annually to U.S. national energy consumption; we project that roughly one quarter of this amount can be attributed to heat loss through the slab edge and the remaining three quarters to deep ground transfers, depending upon climate. With rising concern over national energy use and the impact of greenhouse gas emissions, it is becoming increasingly imperative that all cost-effective efforts to improve building energy efficiency be implemented. Unlike other building envelope components that have experienced efficiency improvements over the years, slab edge heat loss has largely been overlooked. From our vantage point, a marketable slab edge insulation system would offer significant benefits to homeowners, builders, and the society as a whole. Conventional slab forming involves the process of digging foundation trenches and setting forms prior to the concrete pour. Conventional wood form boards (usually 2 x 10's) are supported by vertical stakes on the outer form board surface, and by supporting 'kickers' driven diagonally from the top of the form board into soil outside the trench. Typically, 2 x 10's can be used only twice before they become waste material, contributing to an additional 400 pounds of construction waste per house. Removal of the form boards and stakes also requires a follow-up trip to the jobsite by the concrete subcontractor and handling (storage/disposal) of the used boards. In the rare cases where the slab is insulated (typically custom homes with radiant floor heating), the most practical insulation strategy is to secure rigid foam insulation, such as Dow Styrofoam{trademark}, to the inside of the wooden slab edge forms. An alternative is to clad insulation to the perimeter of the slab after the slab has been poured and cured. In either case, the foam must have a 'termite strip' that prevents termites from creating hidden tunnels through or behind the foam on their way to the wall framing above. Frequently this termite strip is a piece of sheet metal that must be fabricated for each project. The above-grade portion of the insulation also needs to be coated for appearance and to prevent damage from construction and UV degradation. All these steps add time, complexity, and expense to the insulating process.

Vehicular Storage of Hydrogen in Insulated Pressure Vessels  

DOE Green Energy (OSTI)

This paper describes the development of an alternative technology for storing hydrogen fuel onboard automobiles. Insulated pressure vessels are cryogenic-capable pressure vessels that can accept cryogenic liquid fuel, cryogenic compressed gas or compressed gas at ambient temperature. Insulated pressure vessels offer advantages over conventional H{sub 2} storage approaches. Insulated pressure vessels are more compact and require less carbon fiber than GH{sub 2} vessels. They have lower evaporative losses than LH{sub 2} tanks, and are much lighter than metal hydrides. After outlining the advantages of hydrogen fuel and insulated pressure vessels, the paper describes the experimental and analytical work conducted to verify that insulated pressure vessels can be used safely for vehicular H{sub 2} storage. The paper describes tests that have been conducted to evaluate the safety of insulated pressure vessels. Insulated pressure vessels have successfully completed a series of DOT, ISO and SAE certification tests. A draft procedure for insulated pressure vessel certification has been generated to assist in a future commercialization of this technology. An insulated pressure vessel has been installed in a hydrogen fueled truck and it is currently being subjected to extensive testing.

Mbius Graphene Strip as Topological Insulator  

E-Print Network (OSTI)

We study the electronic properties of M\\"{o}bius graphene strip with a zigzag edge. We show that such graphene strip behaves as a topological insulator with a gapped bulk and a robust metallic surface, which enjoys some features due to its nontrivial topology of the spatial configuration, such as the existence of edge states and the non-Abelian induced gauge field. We predict that the topological properties of the M\\"{o}bius graphene strip can be experimentally displayed by the destructive interference in the transmission spectrum, and the robustness of edge states under certain perturbations.

Prospects for highly insulating window systems  

SciTech Connect

Windows and other fenestration systems are often considered the weakest links in energy-efficient residences. This opinion is reinforced by building standards, audit guidelines, and standard window performance evaluation techniques geared toward sizing building HVAC equipment. In this paper we show that it should be possible to design highly insulating windows (U < 0.12 Btu/hr-ft/sup 2/-F) with high solar transmittances (SC > 0.6). If we then view annual window performance from the basic perspective of control of energy flows, we conclude that it should thus be possible to develop a new generation of ''super window'' that will outperform the best insulated wall or roof for any orientation even in a northern climate. We review several technical approaches that suggest how such a window system might be designed and built. These include multiglazed windows having one or more low-emittance coatings and gas-filled or evacuated cavities. Another approach uses a layer of transparent silica aerogel, a microporus material having a conductivity in air of about R7 per inch. We conclude by presenting data on annual energy performance in a cold climate for a range of ''super windows''. 8 refs., 6 figs.

Cold climate foundation insulation retrofit performance  

SciTech Connect

The effectiveness of foundation insulation retrofits in 15 Minnesota houses was evaluated using a before-after experimental method. Nine houses received interior retrofits; six, exterior retrofits. Foundation air leaks were sealed before the preretrofit heating season to control for inadvertent sealing during retrofit. Basement heating supply and return registers were closed in most houses for the 21-month monitoring period, and for all houses the basement was an uncontrolled zone without a thermostat. Homeowners recorded gas and electricity meter readings and furnace and water heater on-times weekly. A load vs. outdoor temperature was used to evaluate changes in energy use. The average whole-house energy savings for the interior and exterior cases were 92 and 24 therm per year, or 7.9% (range - 0.6% to 17.8%) and 3.0% (range -2.9% to 8.3%), respectively. Minimum payback periods for the interior and exterior cases were 12 and 37 years, respectively. For all houses the basement temperature increased between the pre- and post-retrofit periods, and all homeowners reported increased comfort in their basements. Average measured savings were about one-third of those predicted. The results show that the application of insulation in an uncontrolled zone produces highly variable results and has the principal effect of increasing the temperature and comfort of the basement rather than producing cost-effective whole-house energy savings.

Field study of moisture damage in walls insulated without a vapor barrier. Final report for the Oregon Department of Energy  

SciTech Connect

Considerable uncertainty has existed over whether or not wall insulation installed without a vapor barrier causes an increased risk of moisture damage (wood decay) within walls. This report describes the results of one of the first major studies in the country aimed at finding out if such a moisture problem really exists. The exterior walls of a total of 96 homes in Portland, Oregon were opened, of which 70 had retrofitted insulation and 26 were uninsulated and were a control group. The types of insulation included urea-formaldehyde foam (44), mineral wool (16), and cellulose (10). In each opened wall cavity the moisture content of wood was measured and insulation and wood samples were taken for laboratory analysis of moisture content and for the determination of the presence of absence of decay fungi. Foam shrinkage was also measured. To evaluate the possible influence of the relative air tightness of the homes, fan depressurization tests were run using a door blower unit. The field and laboratory test results indicating the lack of a moisture damage problem in existing homes with wood siding in climates similar to that of western Oregon are described along with results of a statistical analysis of the data. Related problems of interest to homeowners and insulation installers are noted. The standard operating procedures used throughout the study are discussed, including the home selection process, quantitative and qualitative techniques used to identify wall locations with the highest moisture content, wall opening and data/sample collection methodology, laboratory analysis of samples, data processing and analysis, and applicability of the results. Recommendations for furutre tests are made. Finally, the potential and desirability for future retrofitting of wall insulation is explored.

Tuning of the Metal-Insulator Transition via Alkali Adsorption Print Tuning of the Metal-Insulator Transition via Alkali Adsorption Print Turning a material from an insulator to a metal, or vice versa, by light irradiation, exposure to electric or magnetic fields, or applying small changes in temperature, pressure, or doping-such intriguing control of a material's electronic properties is possible by exploiting strongly interacting or "correlated" electrons. Now a team of researchers from the University of Kiel in Germany and the ALS has found a novel, surprising way to continuously transform a layered metallic transition-metal compound, TaS2, into an insulator. Using angle-resolved photoemission spectroscopy (ARPES), they have demonstrated that adsorption of alkali atoms onto this material's surface gradually makes it more insulating, although in general, alkali adsorption should lead to more metallic behavior, as alkali atoms easily give away their loosely bound outermost electron.

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

Experiments Provide First Direct Experiments Provide First Direct Signatures of a Topological Insulator - a New Phase of Quantum Matter It has recently been proposed that insulators with large band gap and strong spin-orbit coupling can host a new phase of quantum matter called a topological insulator [1,2]. This exotic phase of matter is a subject of intense research because it is predicted to give rise to dissipationless spin currents [3], quantum entanglements and novel macroscopic behavior that obeys axionic electrodynamics rather than Maxwell's equations [4]. Unlike ordinary quantum phases of matter such as superconductors, magnets or superfluids, topological insulators are not described by a local order parameter associated with a spontaneously broken symmetry but rather by a quantum entanglement of its wave function, dubbed topological order. In a topological insulator this quantum entanglement survives over the macroscopic dimensions of the crystal and leads to surface states that have unusual spin textures.

Examination of insulation wear modes in geothermal logging cables  

DOE Green Energy (OSTI)

The wear mode of the Tetrafluorethylene (TFE) insulation used on an electrical logging cable is described. The cable examined in this study was used repeatedly in various harsh geothermal environments. Considering the amount of abuse the cable was subjected to, the TFE performed very well. Grooves were formed on the outside of the insulation as a result of the fluid pressure and the loading from the inner layer of metal armor. Also, indentations on the inside of the insulation were caused by the insulation molding to the conductor strands. If this mode of wear were to continue, the conductors would eventually protrude from the insulation and short out against each other or the cable armor. 4 refs., 5 figs.

Features of electron mobility in a thin silicon layer in an insulator-silicon-insulator structure  

Science Conference Proceedings (OSTI)

Electron mobility in a thin silicon layer of a metal-insulator-semiconductor-insulator-metal system is studied as a function of longitudinal and transverse electric fields (in wide ranges of their values), temperature in the range 1.7 to 400 K, and changes in {gamma}-ray irradiation conditions. It is shown that, in the temperature range 400 to {approx}100 K, electron mobility increases in accordance with the mechanism of electron scattering at an acoustic phonon, while, with a subsequent decrease in temperature to the temperature of liquid helium, mobility drops because the Coulomb scattering of electrons at charged surface centers starts to dominate. It is demonstrated that as a result of {gamma}-ray irradiation, electron mobility decreases and the degree of this decrease strongly depends on the electrical mode of the sensor during irradiation.

Topological Insulators Avoid the Parity Anomaly  

E-Print Network (OSTI)

The surface of a 3+1d topological insulator hosts an odd number of gapless Dirac fermions when charge conjugation and time-reversal symmetries are preserved. Viewed as a purely 2+1d system, this surface theory would necessarily explicitly break parity and time-reversal when coupled to a fluctuating gauge field. Here we explain why such a state can exist on the boundary of a 3+1d system without breaking these symmetries, even if the number of boundary components is odd. This is accomplished from two complementary perspectives: topological quantization conditions and regularization. We first discuss the conditions under which (continuous) large gauge transformations may exist when the theory lives on a boundary of a higher-dimensional spacetime. Next, we show how the higher-dimensional bulk theory is essential in providing a parity-invariant regularization of the theory living on the lower-dimensional boundary or defect.

MODULAR CORE UNITS FOR A NEUTRONIC REACTOR  

DOE Patents (OSTI)

A modular core unit for use in a nuclear reactor is described. Many identical core modules can be placed next to each other to make up a complete core. Such a module includes a cylinder of moderator material surrounding a fuel- containing re-entrant coolant channel. The re-entrant channel provides for the circulation of coolant such as liquid sodium from one end of the core unit, through the fuel region, and back out through the same end as it entered. Thermal insulation surrounds the moderator exterior wall inducing heat to travel inwardly to the coolant channel. Spaces between units may be used to accommodate control rods and support structure, which may be cooled by a secondary gas coolant, independently of the main coolant. (AEC)

Analysis and testing of multilayer and aerogel insulation configurations  

Science Conference Proceedings (OSTI)

Multilayer insulation systems that have robust operational characteristics have long been a goal of many research projects. Such thermal insulation systems may need to offer some degree of structural support and/or mechanical integrity during loss of vacuum scenarios while continuing to provide insulative value to the vessel. Aerogel-based composite blankets can be the best insulation materials in ambient pressure environments; in high vacuum, the thermal performance of aerogel improves by about one order of magnitude. Standard multilayer insulation (MLI) is typically 50% worse at ambient pressure and at soft vacuum, but as much as two or three orders of magnitude better at high vacuum. Different combinations of aerogel blanket and multilayer insulation materials have been tested at the Cryogenics Test Laboratory of NASA Kennedy Space Center. Analysis performed at Oak Ridge National Laboratory showed an importance to the relative location of the MLI and aerogel blankets. Apparent thermal conductivity testing under cryogenicvacuum conditions was performed to verify the analytical conclusion. Tests results are shown to be in agreement with the analysis which indicated that the best performance is obtained with aerogel layers located in the middle of the blanket insulation system.

Outdoor polymeric insulators long-term exposed to HVDC  

SciTech Connect

Field experience from outdoor polymeric insulators exposed to HVDC under natural contamination conditions is presented. This paper summarizes the peak leakage current statistics, the hydrophobicity and the surface material conditions studied by electron spectroscopy for chemical analysis (ESCA) and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. The results show a strong interrelation between the surface conditions and the performance with respect to leakage currents. Moreover, the results show that the surface conditions and the performance of the insulators exposed to HVDC are rather similar to those of the insulators exposed to HVAC.

Insulation of Pipe Bends Improves Efficiency of Hot Oil Furnaces  

E-Print Network (OSTI)

Thermodynamic analyses of processes indicated low furnace efficiencies on certain hot oil furnaces. Further investigation, which included Infrared (IR) thermography testing of several furnaces, identified extremely hot surfaces on the outside of the convective sections. Consultation with the furnace manufacturer then revealed that furnaces made in the 1960's tended to not insulate the pipe bends in the convective section. When insulation was added within the covers of the pipe bends on one furnace, the energy efficiency improved by approximately 11%. The total savings are approximately 14,000 Million Btu/yr on one furnace. Insulation will be applied to several other furnaces at the site.

New particle-control techniques for gas-insulated apparatus  

SciTech Connect

The feasibilities of two new methods of controlling contaminating particles in gas-insulated apparatus have been experimentally investigated. The first method is to coat the particles with an insulating layer: for the first time it was found that (1) coatings can render harmless particles that would otherwise lower the withstand voltage by factors of 2 to 5 and (2) coatings can be formed on particles residing in the system. The second method, trapping particles in an insulating material, was found effective also, and suitable materials were compounded for different temperature ranges.

Aerogel-Based Insulation for Industrial Steam Distribution Systems  

SciTech Connect

Thermal losses in industrial steam distribution systems account for 977 trillion Btu/year in the US, more than 1% of total domestic energy consumption. Aspen Aerogels worked with Department of Energys Industrial Technologies Program to specify, develop, scale-up, demonstrate, and deliver Pyrogel XT, an aerogel-based pipe insulation, to market to reduce energy losses in industrial steam systems. The product developed has become Aspens best selling flexible aerogel blanket insulation and has led to over 60 new jobs. Additionally, this product has delivered more than ~0.7 TBTU of domestic energy savings to date, and could produce annual energy savings of 149 TBTU by 2030. Pyrogel XTs commercial success has been driven by its 2-4X better thermal performance, improved durability, greater resistance to corrosion under insulation (CUI), and faster installation times than incumbent insulation materials.

DOE Green Energy (OSTI)

This paper describes one approach to the design of a variable-conductance vacuum insulation. In this design, the vacuum insulation consists of a permanently sealed, thin sheet steel, evacuated envelope of whatever geometry is required for the application. The steel envelope is supported internally against the atmospheric pressure loads by an array of discrete, low-conductance, ceramic supports, and radiative heat transfer is blocked by layers of thin metal radiation shields. Thermal conductance through this insulation is controlled electronically by changing the temperature of a small metal hydride connected to the vacuum envelope. The hydride reversibly absorbs/desorbs hydrogen to produce a hydrogen pressure typically within the range from less than 10{sup {minus}6} to as much as 1 torr. Design calculations are compared with results from laboratory tests of bench scale samples, and some possible automotive applications for this variable-conductance vacuum insulation are suggested.
