Filament-strung stand-off elements for maintaining pane separation in vacuum insulating glazing units  

DOE Patents [OSTI]

A vacuum insulating glazing unit (VIGU) comprises first and second panes of transparent material, first and second anchors, a plurality of filaments, a plurality of stand-off elements, and seals. The first and second panes of transparent material have edges and inner and outer faces, are disposed with their inner faces substantially opposing one another, and are separated by a gap having a predetermined height. The first and second anchors are disposed at opposite edges of one pane of the VIGU. Each filament is attached at one end to the first anchor and at the other end to the second anchor, and the filaments are collectively disposed between the panes substantially parallel to one another. The stand-off elements are affixed to each filament at predetermined positions along the filament, and have a height substantially equal to the predetermined height of the gap such that the each stand-off element touches the inner surfaces of both panes. The seals are disposed about the edges of the panes, enclosing the stand-off elements within a volume between the panes from which the atmosphere may be evacuated to form a partial vacuum.

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

Acoustic behavior of triple glazings  

Science Journals Connector (OSTI)

Making of triple glazings is the only way to still improve thermal performances of Insulating Glass Units. Possible ways with double glazings are already in use: increase the space between glasses use low emissivity coatings and special gas with lower thermal conductivity as argon or krypton. Specific acoustic weak point of double glazings is the resonance between the two panes which works as a mass spring mass system and coupling of eigenmodes of panes through the air (gas) cavity. These phenomena are of course still more important with triple glazings as there are two resonances. The paper will give all comparative data concerning thermal and acoustic performances and describe a way to achieve the same single number values of sound transmission loss with triple glazing that with double glazing by adding absorption in the gas cavities.

Performance criteria for center layer of triple glazing  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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.

Investigation of single unit flashovers in HVDC insulator strings  

SciTech Connect (OSTI)

In HVDC transmission lines, a special phenomenon, so called single unit flashover, is observed under some special conditions. Only one or two insulator units repeat flashovers, not resulting in an overall flashover along the string. However, higher magnitudes of audible noise, radio and television interferences, may give a serious problem. Based on the investigation on {+-}500-kV full scale insulator strings, higher occurrence probability of single unit flashovers under cold-wet-switch-on conditions was clarified compared with normal continuous operating voltage conditions. Effectiveness of the newly proposed countermeasures to prevent single unit flashovers was demonstrated by experiments in laboratory and in field.

Evaluation of solar heat gain coefficient for solar-control glazings and shading devices  

SciTech Connect (OSTI)

The determination of solar heat gain coefficient (SHGC) values for complex fenestration systems is required to evaluate building energy performance, to estimate peak electrical loads, and to ensure occupant comfort. In the past, simplified techniques have been used to calculate the values of SHGC for fenestration systems. As glazing systems that incorporate complex geometries become more common, test methods are required to evaluate these products and to aid in the development of new computational tools. Recently, a unique facility and test method for the experimental determination of SHGC values were developed and demonstrated for simple fenestration systems. The study described in this paper further applies this method to a variety of commercially available glazing and shading systems (e.g., heat-absorbing insulated glazing units (IGUs), reflective film and suspended film IGUs), and shading devices (i.e., slat blinds and shades). Testing was conducted in a solar simulator facility using a specially designed window calorimeter. The results of this study demonstrate the feasibility of the solar simulator-based test method for the evaluation of SHGC values for solar-control glazings and shading devices.

Electrochromic Glazings: Animation Parameters  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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.

High Reliability R-10 Windows Using Vacuum Insulating Glass Units  

SciTech Connect (OSTI)

The objective of this effort was for EverSealed Windows (“EverSealed” or “ESW”) to design, assemble, thermally and environmentally test and demonstrate a Vacuum Insulating Glass Unit (“VIGU” or “VIG”) that would enable a whole window to meet or exceed the an R-10 insulating value (U-factor ? 0.1). To produce a VIGU that could withstand any North American environment, ESW believed it needed to design, produce and use a flexible edge seal system. This is because a rigid edge seal, used by all other know VIG producers and developers, limits the size and/or thermal environment of the VIG to where the unit is not practical for typical IG sizes and cannot withstand severe outdoor environments. The rigid-sealed VIG’s use would be limited to mild climates where it would not have a reasonable economic payback when compared to traditional double-pane or triple-pane IGs. ESW’s goals, in addition to achieving a sufficiently high R-value to enable a whole window to achieve R-10, included creating a VIG design that could be produced for a cost equal to or lower than a traditional triple-pane IG (low-e, argon filled). ESW achieved these goals. EverSealed produced, tested and demonstrated a flexible edge-seal VIG that had an R-13 insulating value and the edge-seal system durability to operate reliably for at least 40 years in the harshest climates of North America.

The SHGC for each glazing is extracted from the data and shown to be angle-dependent. The method of extracting the angle-dependent SHGC from the data is checked by comparing the measured SHGC for the clear double glazing to the calculation of OW 4. 1, which is assumed to be correct. Good agreement between the two is found. The measured angle-dependent SHGC`s of the selective glazings are then used to test the OW 4.1 selective glazing calculation and good agreement is again found.

Experimental performance evaluation of aerogel glazing systems  

Science Journals Connector (OSTI)

Energy savings for heating, air conditioning and illuminating plants could be improved by innovative Transparent Insulation Materials (TIMs), which aim to optimize two opposite requirements: transparency and thermal insulation. Aerogel is one of the most promising materials for use in highly energy-efficient windows: in addition to the low thermal conductivity (down to 0.010 W/(m K) in evacuated conditions), a high solar energy and daylight transmittance is achieved. Eight samples were manufactured, by assembling several types of glass with monolithic and granular aerogel in the interspace. U-values slightly higher than 1 W/m2 K were obtained for all the samples. The monolithic aerogel introduced a better light transmittance (?v = 0.60) than granular one (?v = 0.27), while U-values were comparable in non-evacuated conditions. With respect to a conventional window (double glazing with a low-e layer), 55% reduction in heat losses was achieved by monolithic aerogel, with only a 25% reduction in light transmittance; for the granular systems, the reduction was about 25% in heat losses, but 66% in light transmission. In order to evaluate the aerogel employing in buildings, a prototype of an aluminum frame window with granular aerogel in interspace was realized. Thermal and acoustic properties of the prototype were evaluated according to the standards. The thermal transmittance of the innovative glazing system was little lower than 1 W/(m2 K) and it showed also good acoustic properties: the Rw index was 3 dB higher than the one of a conventional window with air in interspace.

Electrochromic Glazings: How they Work  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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.

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  

SciTech Connect (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.

Sound transmission loss of double?glazed window panes—an empirical approach  

Science Journals Connector (OSTI)

There are only a few contributions to the theory of sound transmission loss (STL) of double?glazed window panes e.g. by M. Rehfeld et al. (1996). The situation is nearly the same with the empirical approach of reducing data from laboratory measurements to a simple formula as done by K. Goesele (1977). Goesele inferred a result in terms of the single?number rating according to ISO 717 based on many laboratory STL measurements as described in DIN 52210 and ISO 140. In particular measurements of air?filled double?glazed window panes had been used. Meanwhile the gas fillings changed because the thermal insulation of the window panes had to be increased. In the last five years a large number of STL measurements of double?glazed window panes with different dimensions (pane thicknesses gap between the panes) and gas fillings have been carried out at the Fraunhofer?Institut fuer Bauphysik. From these measurements some typical behaviors of STL versus frequency belonging to specific pane configurations could be derived. This should allow an approximate prediction of the STL for given physical dimensions of double?glazed window panes.

Thermal solar collector with VO2 absorber coating and thermochromic glazing – Temperature matching and triggering  

Science Journals Connector (OSTI)

Abstract Overheating is a common problem both with the use of active and passive solar energy in thermal solar energy systems and in highly glazed buildings, even in central European latitudes. In solar thermal collectors, the elevated temperatures occurring during stagnation result in reduced lifetime of the collector materials. They lead to water evaporation, glycol degradation and stresses in the collector with increasing vapor pressure. Special precautions are necessary to release this pressure; only mechanical solutions exist nowadays. The temperature of degradation of glycols is above 160–170 °C. However, it would be preferable to limit the temperature of the collector to approximately 100 °C, avoiding likewise the evaporation of the used water-glycol mixture. Additionally, the elevated temperatures lead to degradation of the materials that compose the collector, such as sealing, thermal insulation and the selective absorber coating. A new way of protecting solar thermal systems without any mechanical device (e.g. for shading or for pressure release) is proposed. A durable inorganic thermochromic material, which exhibits a change in optical properties at a transition temperature T t , is vanadium dioxide (VO2). At 68 °C, VO2 undergoes a reversible crystal structural phase transition accompanied by a strong variation in optical properties. Therefore, a dynamical switching of the thermal emittance ? th can be achieved by VO2. By doping the material with tungsten, it is possible to lower the transition temperature making it suitable as a glazing coating. The possibility of using the switch in emittance of the absorber coating in order to trigger the transition of a thermochromic coating on the glazing of the solar collector has been studied. An analytical approach yielded the required transition temperature of such a switching glazing. The fascinating optical properties of these switchable films elucidate the way towards novel intelligent thermal solar collector materials.

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.

Optical and thermal characteristics of transparent single-glazed hemispherical domed skylights under sun and sky light are evaluated based on an optical model for domed skylights. The optical model is based on tracing the beam and diffuse radiation transmission through the dome surface. A simple method is proposed to replace single-glazed hemispherical domed skylights by optically and thermally equivalent single-glazed planar skylights to accommodate limitations of energy computer programs. Under sunlight, single-glazed hemispherical domed skylights yield slightly lower equivalent solar transmittance and solar heat gain coefficient (SHGC) at near normal zenith angles than those of single-glazed planar skylights. However, single-glazed hemispherical domed skylights yield substantially higher equivalent solar transmittance and SHGC at high zenith angles and around the horizon. Under isotropic skylight, single-glazed hemispherical domed skylights yield slightly lower equivalent solar transmittance and SHGC than those of single-glazed planar skylights. Daily solar heat gains of single-glazed hemispherical domed skylights are higher than those of single-glazed horizontal planar skylights in both winter and summer. In summer, the solar heat gain of single-glazed hemispherical domed skylights can reach 3% to 9% higher than those of horizontal single-glazed planar skylights for latitudes varying between 0 and 55{degree} (north/south). In winter, however, the solar heat gains of single-glazed hemispherical domed skylights increase significantly with the increase of the site latitude and can reach 232% higher than those of horizontal single-glazed planar skylights, particularly for high latitude countries.

Multipurpose characterization of glazing systems with silica aerogel: In-field experimental analysis of thermal-energy, lighting and acoustic performance  

Science Journals Connector (OSTI)

Abstract Thermal-energy, acoustic and lighting performance of innovative glazing systems with aerogel inclusion is evaluated through in-field experiments. The study is carried out by monitoring two dedicated prototype buildings located in central Italy, and the consistency of results with in-lab analyses is investigated. Analyses showed that aerogel can decrease energy consumption for heating by up to 50% in winter, and its capability to keep the thermal zone warmer even several days after that the heating system is switched off. Acoustic analyses confirmed in-lab measurements, showing aerogel capability to increase the façade acoustic insulation index by 3 dB. Lighting analyses showed aerogel effect to lower the daily average illuminance level by about 10% during sunny days. In cloudy weather conditions, with low level of solar radiation and indoor illuminance, the effect was relatively higher. In those cases when windows include shading elements such as protruding roof or deep window pad, aerogel effect was not clearly identified through continuous monitoring. The results of this integrated in-field experimental campaign showed that aerogel filled glazing cameras represent effective and innovative solutions for energy saving in winter, useful for improving acoustic façade performance with limited penalties in terms of daylighting.

Spectral effects on the transmittance, solar heat gain, and performance rating of glazing systems  

Science Journals Connector (OSTI)

This study investigates the potential changes in Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT) ratings of vertical or tilted glazing systems that would result from a deliberate change in the reference spectrum used as Spectral Weighting Function (SWF). This SWF is necessary to evaluate broadband-average optical properties from their spectral values, and obtain the desired rating of such bulk properties. The \\{SWFs\\} currently specified by rating institutions in Europe and North America for SHGC and VT are now outdated, and their inadequacies are discussed. Six potential replacements, which have been recently adopted by ASTM are described, including three direct irradiance spectra and three global irradiance spectrum incident on tilted surfaces of various tilts (20°, 37° and 90°). Some of these spectra have been tailored for use in building energy applications, including Building-Integrated Photovoltaics (BIPV). The effect of tilt on the U-factor and hence SHGC of glazing systems used for skylights on roofs is discussed, using a representative dataset of 37 glazing system specimens. The spectral effects on SHGC induced by a change in the current North American SWF are also obtained for this dataset, and show small to moderate deviations from current ratings (?2% to +7% for windows, and ?3% to +11% for skylights). The variations in VT are within ±2% for most glazing systems. To remove the current inconsistency in the \\{SWFs\\} used for SHGC and VT, it is recommended that a single SWF be used for both properties. For improved accuracy and reliance on active standards, it is also recommended that the SWF for SHGC and VT be either one of the two recent ASTM G197-08 global irradiance spectra, depending on application (incidence on a vertical surface for window applications, and incidence on a 20°-tilted surface for skylight applications). No change in colorimetric calculations (based on the D65 illuminant) is recommended, however.

Glazing Glazing Double-Glazed, Clear Glass This figure illustrates the performance of a typical double-glazed unit with two lites of clear glass. 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. These values represent double glazing with a 1/2" air gap.

On the feasibility of colored glazed thermal solar collectors based on thin film interference filters  

Science Journals Connector (OSTI)

Glazed thermal solar collectors, typically equipped with black, optical selective absorber sheets, exhibit good energy conversion efficiency. However, the black color, and sometimes the visibility of tubes and corrugations of the metal sheets, limit the architectural integration into buildings. In order to overcome this drawback, interference filters are considered as a promising approach. Multilayered thin film stacks deposited on the cover glass can produce a colored reflection hiding the black absorber without a great loss of energy. These interference filters are designed and optimized by numerical simulation. Such coatings are deposited by vacuum processes (e.g. magnetron sputtering) and also via the SolGel method. Optical measurements, such as real-time laser-reflectometry and spectrophotometry, are suitable to determine film thicknesses and optical constants of individual layers, and to measure color coordinates and solar transmittance for the multilayer stacks. Advantages and disadvantages of the different coating processes are discussed.

Topological insulators and superconductors  

Science Journals Connector (OSTI)

Topological insulators are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors. They are characterized by a full insulating gap in the bulk and gapless edge or surface states which are protected by time-reversal symmetry. These topological materials have been theoretically predicted and experimentally observed in a variety of systems, including HgTe quantum wells, BiSb alloys, and Bi2Te3 and Bi2Se3 crystals. Theoretical models, materials properties, and experimental results on two-dimensional and three-dimensional topological insulators are reviewed, and both the topological band theory and the topological field theory are discussed. Topological superconductors have a full pairing gap in the bulk and gapless surface states consisting of Majorana fermions. The theory of topological superconductors is reviewed, in close analogy to the theory of topological insulators.

Chapter 9 - Pipeline Insulation  

Science Journals Connector (OSTI)

Oilfield pipelines are insulated mainly to conserve heat. The need to keep the product in the pipeline at a temperature higher than the ambient could exist for the following reasons: preventing the formation of gas hydrates, preventing the formation of wax or asphaltenes, enhancing the product flow properties, increasing the cooldown time after shutting down, and meeting other operational/process equipment requirements. On the other hand, in liquefied gas pipelines, such as LNG, insulation is required to maintain the cold temperature of the gas to keep it in a liquid state. This chapter describes the commonly used insulation materials, insulation finish on pipes, and general requirements for insulation of offshore and deepwater pipelines.

Integrated solar heating unit  

SciTech Connect (OSTI)

This patent describes an integral solar heating unit with an integral solar collector and hot water storage system, the unit comprising: (a) a housing; (b) a flat plate solar collector panel mounted in the housing and having a generally horizontal upper edge and an uninsulated, open back surface; (c) a cylindrical hot water tank operatively connected to the solar collector panel and mounted in the housing generally parallel to and adjacent to the upper edge; (d) the housing comprising a hood around the tank a pair of side skirts extending down at the sides of the panel. The hood and side skirts terminate at lower edges which together substantially define a plane such that upon placing the heating unit on a generally planar surface, the housing substantially encapsulates the collector panel and hot water tank in a substantially enclosed air space; (e) the collector including longitudinally extended U-shaped collector tubes and a glazed window to pass radiation through to the collector tubes, and a first cold water manifold connected to the tubes for delivering fresh water thereto and a second hot water manifold connected to the tubes to remove heated water therefrom. The manifolds are adjacent and at least somewhat above and in direct thermal contact with the tank; and, (f) the skirts and hood lapping around the collector panel, exposing only the glazed window, such that everything else in the heating unit is enclosed by the housing such that heat emanating from the uninsulated, open back face of the collector and tank is captured and retained by the housing to warm the manifolds.

Insulation fact sheet  

SciTech Connect (OSTI)

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.

Constraints on topological order in Mott Insulators  

E-Print Network [OSTI]

We point out certain symmetry induced constraints on topological order in Mott Insulators (quantum magnets with an odd number of spin $\\tfrac{1}{2}$ per unit cell). We show, for example, that the double semion topological order is incompatible with time reversal and translation symmetry in Mott insulators. This sharpens the Hastings-Oshikawa-Lieb-Schultz-Mattis theorem for 2D quantum magnets, which guarantees that a fully symmetric gapped Mott insulator must be topologically ordered, but is silent on which topological order is permitted. An application of our result is the Kagome lattice quantum antiferromagnet where recent numerical calculations of entanglement entropy indicate a ground state compatible with either toric code or double semion topological order. Our result rules out the latter possibility.

A Study of the Filling of Wall Cavities With Retrofit Wall Insulation.  

SciTech Connect (OSTI)

The Pacific Northwest Power Marketing Agency, the Bonneville Power Administration (BPA), conducted a retrofit wall insulation study to determine the effects of various obstructions within a wall cavity, where voids are likely to occur, and preferred filling methods and material types. The insulation test structure was composed of four 8-foot /times/ 12-foot walls, and was built using standard construction practices. The inside walls were clear plastic glazing, instead of gypsum board, to enable viewing of the filling process. A total of eight tests were performed: four cellulose, two rockwool, and two fiberglass. One- and two-hole filling methods were observed. All insulations were found to perform in the same basic manner with all experiencing the same problem areas. Common installer problems were empty spaces at the tops of cavities and missed cavities, especially above headers. Wiring and lath and plaster consistently caused reduced insulation densities in cavities. The problems with wiring, lath and plaster, and other features in the wall cavities were avoided with the use of a filler tube. The filler tube also provided a more consistent fill along the length of the entire cavity. 2 figs., 3 tabs.

Detailed thermal performance data on conventional and highly insulating window systems  

SciTech Connect (OSTI)

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.

Cooper Pairs in Insulators?!  

ScienceCinema (OSTI)

Nearly 50 years elapsed between the discovery of superconductivity and the emergence of the microscopic theory describing this zero resistance state. The explanation required a novel phase of matter in which conduction electrons joined in weakly bound pairs and condensed with other pairs into a single quantum state. Surprisingly, this Cooper pair formation has also been invoked to account for recently uncovered high-resistance or insulating phases of matter. To address this possibility, we have used nanotechnology to create an insulating system that we can probe directly for Cooper pairs. I will present the evidence that Cooper pairs exist and dominate the electrical transport in these insulators and I will discuss how these findings provide new insight into superconductor to insulator quantum phase transitions.

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

Conjugate heat transfer in a room with a laminated glazing with CuS or CuS–Cu2?xSe  

Science Journals Connector (OSTI)

Abstract A numerical study of the heat transfer in a room with a laminated glazing wall with solar control films is presented. The thermal evaluation was performed on three different configurations of the laminated glazing, with films of CuS–Cu2?xSe or CuS using polyvinyl butyral (PVB) and/or polyethylene terephthalate (PET). For a reference case, a single glazing was evaluated. In order to observe the effect of the conjugate heat transfer on the inside environment of the system, thermal efficiency (?t) was defined; this is the ratio between the total heat flux towards the inside environment regarding the incident solar energy on glazing. The results show that the adhesion of two solar control films at laminated glazing presents better values of thermal efficiency for different values of solar radiation (G) and outside temperature (Text). Also, with the aim of applying these results to other contexts, we computed the values obtained for the solar heat gain coefficient (SHGC). The SHGC was determined for the summer conditions stated in ISO 15099 and ASHRAE. The SHGC results were predicted in a range of 0.360 ? SHGC ? 0.499 and 0.504 ? SHGC ? 0.595 for the conditions of ISO 15099 and ASHRAE, respectively.

Spectrally selective laminated glazing consisting of solar control and heat mirror coated glass: preparation, characterization and modelling of heat transfer  

Science Journals Connector (OSTI)

In this study, solar control coatings were prepared by sequential depositions of thin films of ZnS (40 nm)–CuS (150 nm) and ZnS (40 nm)–Bi2S3 (75 nm)–CuS (150 nm) from chemical baths on 3 mm thick commercial sheet glass. These were laminated to 3 mm thick clear glass or commercially available SnO2 based heat mirror coating of sheet resistance 15 ? on float glass of 3 mm thickness using a poly(ethylene vinyl acetate), EVA, sheet of 0.36 mm thickness in a vacuum process at 120 °C for 30 min. In total, the thickness of the glazing was 6.35 mm. The glazings possess visible transmittance, weighted for D65 solar spectra and sensitivity of the human eye for daylight vision, of 36% or 14% with solar absorptance of 71% or 78% depending on the coating type, i.e ZnS–CuS or ZnS–Bi2S3–CuS-heat mirror respectively. The solar heat gain coefficient (SHGC) was evaluated for these glazings at exterior temperatures of 15 and 32 °C for an exterior convective heat transfer coefficient (hex) of 6–100 Wm?2 K?1 using a mathematical model. The model predicts the extent of reduction in SHGC through the presence of the heat mirror coating as a function of hex and hence helps to decide on the relative benefit, which may be derived through their use in different locations. Though the deposition technique mentioned here involves longer duration compared with vacuum techniques, it may be developed into a low throughput, low-capital alternate technology for small-scale production.

Highly Insulating Windows - Cost  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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.

Frames Frames Research performed at the Norwegian University of Science and Technology and LBNL has identified various highly insulating frame solutions. A report was released in 2007 describing some of these frames. 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/m2K ), 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.

Smoldering combustion hazards of thermal insulation materials  

SciTech Connect (OSTI)

Work on the smolder ignitability in cellulosic insulation and on thermal analytical characterization of the oxidation of this material is presented. Thermal analysis (TGA and DSC) shows that both retarded and unretarded cellulosic insulation oxidizes in two overall stages, both of which are exothermic. The second stage (oxidation of the char left as a residue of the first stage) is much more energetic on a unit mass basis than the first. However, kinetics and a sufficient exothermicity make the first stage responsible for ignition in most realistic circumstances. Existing smolder retardants such as boric acid have their major effect on the kinetics of the second oxidation stage and thus produce only a rather small (20/sup 0/C) increase in smolder ignition temperature. Several simplified analogs of attic insulations have been tested to determine the variability of minimum smolder ignition temperature. These employed planar or tubular constant temperature heat sources in a thermal environment quite similar to a realistic attic application. Go/no-go tests provided the borderline (minimum) ignition temperature for each configuration. The wide range (150/sup 0/C) of minimum ignition temperatures confirmed the predominant dependence of smolder ignition on heat flow geometry. Other factors (bulk density, retardants) produced much less effect on ignitability.

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 there between 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 various 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. 35 figs.

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.

Insulation products promote thermal efficiency  

SciTech Connect (OSTI)

The judicious use of thermal insulation products in non-residential buildings can provide a number of advantages including increased energy efficiency, lower first costs (by avoiding overside HVAC systems), improved fire safety and better acoustics. Thermal insulation products are those products which retard the flow of heat energy. Materials include glass, plastics, and organic materials such as wood fibers, vermiculite and perlite. Forms range from the familiar batts and blankets of glass fibers to foamed plastic, rigid boards, losse fill and systems combining two or more products, such as polystyrene boards covered with insulating plaster. The R values of selected insulation materials with a cost/sq. ft. of each material at R 10 are given. Costs cover both the material and installation and may vary depending on local conditions.

The influence of different electricity-to-emissions conversion factors on the choice of insulation materials  

Science Journals Connector (OSTI)

Abstract The current practice of building energy upgrade typically uses thick layers of insulation in order to comply with the energy codes. Similarly, the Norwegian national energy codes for residential buildings are moving towards very low U-values for the building envelope. New and more advanced materials, such as vacuum insulation panels (VIPs) and aerogel, have been presented as alternative solutions to commonly used insulation materials. Both aerogel and \\{VIPs\\} offer very high thermal resistance, which is a favourable characteristic in energy upgrading as the same insulation level can be achieved with thinner insulation layers. This paper presents the results of energy use and lifecycle emissions calculations for three different insulation materials (mineral wool, aerogel, and vacuum insulation panels) used to achieve three different insulation levels (0.18 W/m2 K, 0.15 W/m2 K, and 0.10 W/m2 K) in the energy retrofitting of an apartment building with heat pump in Oslo, Norway. As advanced insulation materials (such as VIP and aerogel) have reported higher embodied emissions per unit of mass than those of mineral wool, a comparison of performances had to be based on equivalent wall U-values rather than same insulation thicknesses. Three different electricity-to-emissions conversion factors (European average value, a model developed at the Research Centre on Zero Emission Buildings – ZEB, and the Norwegian inland production of electricity) are used to evaluate the influence of the lifecycle embodied emissions of each insulation alternative. If the goal is greenhouse gas abatement, the appraisal of buildings based solely on their energy use does not provide a comprehensive picture of the performance of different retrofitting solutions. Results show that the use of the conversion factor for Norwegian inland production of electricity has a strong influence on the choice of which of the three insulation alternatives gives the lowest lifecycle emissions.

Appraisal of thermal performance of a glazed office with a solar control coating: Cases in Mexico and Canada  

Science Journals Connector (OSTI)

The use of solar passive strategies such as new solar control coatings on windows for buildings with large glazed areas, have recently become important and helpful tools, mainly because these developments help to reduce heat gains and/or losses through transparent materials, diminishing energy loads, and improving the environment inside buildings. This paper shows an assessment of the thermal performance for an office on top of a building with four different configurations of window glass, and their influence on the indoor conditions. The window glass configurations are: clear glass, glass-film (SnS–CuxS solar control coating), double-glass-film, and double clear glass. The simulations were carried out using weather data from Mexico City and Ottawa, which are a good representation of two extreme weather conditions, in order to assess the thermal behaviour inside offices, such as energy loads, costs for air conditioning, and the influence of interior heat transfer coefficient correlations. The results indicate that the glass-film proves to be the less appropriate configuration due to the high temperatures reached on the film surface, which has an impact on the air temperatures inside the office and contributes to increase the energy consumption. In general, the double glass-film configuration results to be adequate for both climates, nevertheless it shows a better performance for Ottawa than Mexico City, where a simple double clear glass would work the same way.

Approximating Metal-Insulator Transitions  

E-Print Network [OSTI]

We consider quantum wave propagation in one-dimensional quasiperiodic lattices. We propose an iterative construction of quasiperiodic potentials from sequences of potentials with increasing spatial period. At each finite iteration step the eigenstates reflect the properties of the limiting quasiperiodic potential properties up to a controlled maximum system size. We then observe approximate metal-insulator transitions (MIT) at the finite iteration steps. We also report evidence on mobility edges which are at variance to the celebrated Aubry-Andre model. The dynamics near the MIT shows a critical slowing down of the ballistic group velocity in the metallic phase similar to the divergence of the localization length in the insulating phase.

Microstructures and properties of laser-glazed plasma-sprayed ZrO{sub 2}-YO{sub 1.5}/Ni-22Cr-10Al-1Y thermal barrier coatings  

SciTech Connect (OSTI)

Thermal barrier coatings (TBCs) consisting of two layers with various yttria contents (ZrO{sub 2}-YO{sub 1.5}/Ni-22Cr-10Al-1Y) were plasma sprayed, and parts of the various specimens were glazed by using a pulsed CO{sub 2} laser. All the specimens were then subjected to furnace thermal cycling tests at 1,100 C; the effect of laser glazing on the durability and failure mechanism of the TBCs was then evaluated. From these results, two models were developed to show the failure mechanism of as-sprayed and laser-glazed TBCs: model A, which is thermal-stress dominant, and model V, which is oxidation-stress dominant. For top coats containing cubic phase, cubic and monoclinic phases, or tetragonal and a relatively larger amount of monoclinic phases, whose degradation is thermal-stress dominant, laser glazing improved the durability of TBCs by a factor of about 2 to 6. Segmented cracks that occurred during glazing proved beneficial for accommodating thermal stress and raising the tolerance to oxidation, which resulted in a higher durability. Thermal barrier coatings with top coats containing tetragonal phase had the highest durability. Degradation of such TBCs resulted mainly from oxidation of the bond coats. For top coats with a greater amount of monoclinic phase, thermal mismatch stress occurred during cooling and detrimentally affected durability.

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.

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.

Welcome to the Efficient Windows Collaborative  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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

Magnetically insulated transmission line oscillator  

DOE Patents [OSTI]

A magnetically insulated transmission line oscillator employs self-generated magnetic fields to generate microwave energy. An anode of the oscillator includes slow-wave structures which are formed of a plurality of thin conductive vanes defining cavities therebetween, and a gap is formed between the anode and a cathode of the oscillator. In response to a pulsed voltage applied to the anode and cathode, self-generated magnetic fields arfe produced in a cross-field orientation with respect to the orientation of the electric field between the anode and the cathode. The cross-field magnetic fields insulate the flow of electrons in the gap and confine the flow of electrons within the gap.

Noise?insulation requirements for multi?family dwellings  

Science Journals Connector (OSTI)

Noise insulation standards are part of the California Administrative Code (Title 25 Section 1092). These standards apply to all new multi?family dwelling units such as hotels apartments duplexes townhouses and condominium units. Detached single?family dwellings are specifically excluded. The standards establish minimum requirements for the isolation of interior spaces from exterior noise and set minimum ratings for noise insulation of partitions between dwelling units. A community noise equivalent level (CNEL) of 45 dB is set as the maximum for intrusive noise from exterior sources such as rail or road traffic or aircraft operations. American Society for Testing and Materials (ASTM) testing procedures for party wall and floor/ceiling system sound transmission provide the basis for setting minimum acceptable performance for separations between units. As a consultant to builders planners and architects the site planning and design of residential projects have been examined and field evaluations have been performed on completed projects. Building designs and the selection of suitable building elements (wall construction composites window assemblies vent configurations etc.) which assure compliance with the standards have been identified. The paper provides a brief description of the standards their enforcement pitfalls and an assessment of their impact on residential construction in California.

Critical insulation thickness for maximum entropy generation  

Science Journals Connector (OSTI)

Critical insulation thickness is known to refer to the insulation thickness that maximises the rate of heat transfer in cylindrical and spherical systems. The same analogy is extended to the rate of entropy generation in the present study. The possible critical insulation thickness that yields a maximum rate of entropy generation is investigated. Entropy generation is related to heat transfer through and temperature distribution within the insulation material. It is found that there exists a critical insulation thickness for maximising the rate of entropy generation that is a function of the Bi number and the surface to ambient temperature ratio. The solution of such critical thickness is formulated analytically for both cylindrical and spherical geometries. It is also found that the critical insulation thickness for the rate of entropy generation does not coincide with that for the rate of heat transfer.

Topological Insulators in Three Dimensions  

Science Journals Connector (OSTI)

We study three-dimensional generalizations of the quantum spin Hall (QSH) effect. Unlike two dimensions, where a single Z2 topological invariant governs the effect, in three dimensions there are 4 invariants distinguishing 16 phases with two general classes: weak (WTI) and strong (STI) topological insulators. The WTI are like layered 2D QSH states, but are destroyed by disorder. The STI are robust and lead to novel “topological metal” surface states. We introduce a tight binding model which realizes the WTI and STI phases, and we discuss its relevance to real materials, including bismuth.

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.

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.

Excavationless Exterior Foundation Insulation Field Study  

SciTech Connect (OSTI)

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. However, such an approach can be very costly and disruptive when applied to an existing home, requiring deep excavation around the entire house. The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home. The approach consisted of using hydrovac excavation technology combined with a liquid insulating foam. The team was able to excavate a continuous 4" wide by 4' to 5' deep trench around the entire house, 128 linear feet, except for one small part under the stoop that was obstructed with concrete debris. The combination pressure washer and vacuum extraction technology also enabled the elimination of large trenches and soil stockpiles normally produced by backhoe excavation. The resulting trench was filled with liquid insulating foam, which also served as a water-control layer of the assembly. The insulation was brought above grade using a liquid foam/rigid foam hybrid system and terminated at the top of the rim joist. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

Insulation failure assessment under random energization overvoltages  

SciTech Connect (OSTI)

This paper offers a new simple approach to the evaluation of the risk of failure of external insulation in view of their known probabilistic nature. This is applied to EHV transmission systems subjected to energization overvoltages. The randomness, both in the applied stresses and insulation`s withstand characteristics are numerically simulated and then integrated to assess the risk of failure. Overvoltage control methods are accounted for, such as the use of pre-insertion breaker resistors, series capacitive compensation, and the installation of shunt reactors.

Electrical Strength of Multilayer Vacuum Insulators  

SciTech Connect (OSTI)

The electrical strength of vacuum insulators is a key constraint in the design of particle accelerators and pulsed power systems. Vacuum insulating structures assembled from alternating layers of metal and dielectric can result in improved performance compared to conventional insulators, but previous attempts to optimize their design have yielded seemingly inconsistent results. Here, we present two models for the electrical strength of these structures, one assuming failure by vacuum arcing between adjacent metal layers and the other assuming failure by vacuum surface flashover. These models predict scaling laws which are in agreement with the experimental data currently available.

Foam insulation for a liquid oxygen densifier  

Science Journals Connector (OSTI)

Analyses indicated that it would not be cost effective to vacuum insulate a 7 foot diameter by 30 foot long liquid nitrogen vessel for a launch facility liquid oxygen densifier. Foam insulation appeared to be the logical choice for this infrequently used ground support equipment but the history of foam problems due to cracking, adhesive failure and internal shearing weighed against the use of commercial spray-on material. These problems were solved with a system consisting of alternate sealing and flexible foam layers: (1) an inner membrane sealed to itself but not attached to the cold shell or pipe; (2) a flexible foam insulation layer; (3) a vapor-tight sealing membrane; (4) a second flexible foam insulation layer and (5) an outer aluminized sealing membrane. The second and subsequent layers are sealed to each underlying layer by flexible foam contact adhesive. The inner sealing membrane is particularly vital in that it allows the first foam layer to expand and contract as the tank temperature changes and it also protects the tank from chloride corrosion from the foam. This paper describes preliminary testing to prove out the system and the steps taken to install flexible foam insulation on the oxygen densifier vessel.

12 - Life cycle assessment (LCA) of building thermal insulation materials  

Science Journals Connector (OSTI)

Abstract: In this chapter thermal insulation materials and types of plaster and their properties are described. The impact of the selected thermal insulation materials and plaster on the environment is assessed using LCA analysis. A method of assessing the ecological and economic benefits resulting from thermal insulation of the external walls of buildings is proposed. On this basis, ecological and economic payback periods for thermal insulation are defined as well as the ecological efficiency of thermal insulation. The conducted analyses conclude that thermal insulation of the external walls of buildings is environmentally favourable.

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.

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. The insulating phase disappears above a critical number of four-component fermion flavors $4 < N_f^{\\text{crit}} < 6$. Our data are consistent with a second-order transition.

The space between the thermal insulating harrier and the reactor vessel forms a chamber which can be flooded with cooling water through passive valving to directly cool the reactor vessel in the event of a severe accident. The passive inlet valve for the cooling water includes a buoyant door that is normally maintained sealed under its own weight and floats open when the cavity is Hooded. Passively opening steam vents are also provided.

Thermal radiative properties of phenolic foam insulation  

Science Journals Connector (OSTI)

Thermal insulation has long been an important subject in engineering. Foam insulations have become the most widely used insulations due to their low cost and ease of procesing. In recent years, phenolic foams find increasing applications because of their fire retardation. This paper presents experimental results of thermal radiative properties of phenolic foams, with or without activated carbon. Transmittance spectra were first taken using FTIR for samples of various densities. Extinction coefficient spectra were then obtained by applying Beer's law. Finally, by using the diffusion approximation, the Rosseland mean extinction coefficients and radiative thermal conductivities were obtained for various temperatures. Results show that the extinction coefficient increases with sample density. The addition of activated carbon increases the extinction coefficient slightly.

Massive Dirac surface states in topological insulator/magnetic insulator heterostructures  

Science Journals Connector (OSTI)

Topological insulators are new states of matter with a bulk gap and robust gapless surface states protected by time-reversal symmetry. When time-reversal symmetry is broken, the surface states are gapped, which induces a topological response of the system to electromagnetic field—the topological magnetoelectric effect. In this paper we study the behavior of topological surface states in heterostructures formed by a topological insulator and a magnetic insulator. Several magnetic insulators with compatible magnetic structure and relatively good lattice matching with topological insulators Bi2Se3, Bi2Te3, Sb2Te3 are identified, and the best candidate material is found to be MnSe, an antiferromagnetic insulator. We perform first-principles calculations in Bi2Se3/MnSe superlattices and obtain the surface state band structure. The magnetic exchange coupling with MnSe induces a gap of ?54 meV at the surface states. In addition we tune the distance between Mn ions and the topological insulator surface to study the distance dependence of the exchange coupling.

Test Report: Cost Effective Foundation Insulation  

SciTech Connect (OSTI)

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.

Development and Testing of Insulated Drill Pipe  

SciTech Connect (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.

Finite element analysis of substation composite insulators  

Science Journals Connector (OSTI)

Composite insulators are rapidly replacing their porcelain counterparts in electrical substation applications. These insulators consist of a glass-reinforced polymer (GRP) rod, with two metal end fittings radially crimped onto the ends of the rod during assembly. In this paper, axisymmetric finite element models are developed to evaluate the mechanical performance of composite insulators under externally applied axial compression. The analyses are performed by assuming both a perfectly bonded interface between the composite rod and the end fittings, and an imperfect interface which permits large relative sliding with Coulomb friction. Results indicate that the perfect interface model is unrealistic since it predicts singular stresses at the interface comer and an overall linear structural response. On the other hand, the imperfect interface model is found to simulate accurately the structural non-linearity caused by relative sliding of the GRP rod within the end fittings. The imperfect interface model has therefore been used to evaluate the effects of interface friction, and the extent of crimping, on the maximum load-bearing capacity of substation composite insulators.

Engineering design of the Z magnetically-insulated transmission lines and insulator stack  

SciTech Connect (OSTI)

A 3.3 m diameter cylindrical insulator stack and a set of 3 m diameter conical magnetically insulated transmission lines (MITLs) were built for the Z accelerator. The 1.7 m tall insulator stack operates at {approx}20 MA and 2.5-3.5 MV, and was instrumented with 12 current and 24 voltage monitors. The insulator stack was concentrically and azimuthally aligned within 1.5 mm. The stack, containing 22 crosslinked polystyrene insulators and 18 grading rings, was designed to provide vertical stability for the MITLs and to resist radial buckling. 2-D and 3-D static finite element analyses (FEA) were used in designing the MITLs to limit gravity deflections to less than .25 mm. 2-D FEA dynamic analyses were done to predict motion and to help design features to restrict damage. Each MITL is divided into four concentric zones which fasten together in a way which facilitates fabrication, limits the extent of possible damage and allows for future changes at minimal cost. The tapered MITLs are supported by feedthrough rings in the insulator stack so that the gaps at small radius are adjustable from 0 to 22 mm. The MITL anodes were instrumented with 24 current monitors and have 48 additional diagnostic locations available. The MITLs were fabricated from 304L stainless steel except the outer anode sections, which were made from 6061-T6 aluminum alloy. Procedures were developed for fabrication of the large and small diameter MITL cones, as well as for the feedthrough rings and grading rings of the stack. The power-flow surfaces were successfully machined to within {+-}.25 mm of the specified contours. A large, multi-trolley MITL handling system was designed to allow for removal, cleaning and replacement of the MITLs for each shot, at a shot rate of 1.5 shots/day. Additional equipment allows for cleaning of the insulators.

Topological Response Theory of Doped Topological Insulators  

Science Journals Connector (OSTI)

We generalize the topological response theory of three-dimensional topological insulators (TI) to metallic systems—specifically, doped TI with finite bulk carrier density and a time-reversal symmetry breaking field near the surface. We show that there is an inhomogeneity-induced Berry phase contribution to the surface Hall conductivity that is completely determined by the occupied states and is independent of other details such as band dispersion and impurities. In the limit of zero bulk carrier density, this intrinsic surface Hall conductivity reduces to the half-integer quantized surface Hall conductivity of TI. Based on our theory we predict the behavior of the surface Hall conductivity for a doped topological insulator with a top gate, which can be directly compared with experiments.

Vacuum insulation properties of phenolic foam  

Science Journals Connector (OSTI)

Characteristic properties of phenolic foam as the interstitial material of a vacuum insulation panel are investigated experimentally. For the measurement of effective thermal conductivity, a vacuum guarded hot plate (VGHP) apparatus is used and the conductivity is measured at various vacuum levels. Radiative properties are found using a Fourier transform infrared spectroscopy (FT-IR) device. Solid conductivity is estimated using the porosity of the foam. Effective thermal conductivity at high level of vacuum is measured to be 5 mW/m K which is sum of solid conductivity (2.56 mW/m K) and radiative conductivity (2.44 mW/m K) with 5% of measurement uncertainty. The pore size of the foam is estimated to be 260 ?m using rarefied gas conduction theory. This ensures insulation performance of phenolic foam up to about 10?3 atm. Other practical characteristics of phenolic foam as the VIP core material are also discussed.

This report explored the regulatory impact and cost-benefit of a robotic thermal asbestos pipe-insulation removal system over the current manual abatement work practice. The authors are currently in the second phase of a two-phase program to develop a robotic asbestos abatement system, comprised of a ground-based support system (including vacuum, fluid delivery, computing/electronics/power, and other subsystems) and several on-pipe removal units, each sized to handle pipes within a given diameter range. The intent of this study was to (i) aid in developing design and operational criteria for the overall system to maximize cost-efficiency, and (ii) to determine the commercial potential of a robotic pipe-insulation abatement system.

Superconducting nano-layer coating without insulator  

E-Print Network [OSTI]

The superconducting nano-layer coating without insulator layer is studied. The magnetic-field distribution and the forces acting on a vortex are derived. Using the derived forces, the vortex-penetration field and the lower critical magnetic field can be discussed. The vortex-penetration field is identical with the multilayer coating, but the lower critical magnetic field is not. Forces acting on a vortex from the boundary of two superconductors play an important role in evaluations of the free energy.

Topological insulators with arbitrarily tunable entanglement  

E-Print Network [OSTI]

We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to demonstrate that the area law contribution can be tuned to an arbitrarily small value, but is topologically protected from vanishing exactly. We prove this by introducing novel methods to bound entanglement entropies from correlations using perturbation bounds, drawing intuition from ideas of quantum information theory. This rigorous approach is complemented by an intuitive understanding in terms of entanglement edge states. These insights have a number of important consequences: The area law has no universal component, no matter how small, and the entanglement scaling cannot be used as a faithful diagnostic of topological insulators. This holds for all Renyi entropies which uniquely determine the entanglement spectrum which is hence also non-universal. The existence of arbitrarily weakly entangled topological insulators furthermore opens up possibilities of devising correlated topological phases in which the entanglement entropy is small and which are thereby numerically tractable, specifically in tensor network approaches.

The proposal has now been realized by an international collaboration led by researchers from Princeton University who studied the electronic structure of insulating alloys of bismuth and antimony by means of angle-resolved photoemission spectroscopy (ARPES) and spin-resolved ARPES. Their results constitute the first direct experimental evidence of a topological insulator in nature that is fully quantum entangled. In the future, a detailed study of topological order and quantum entanglement using their method can potentially pave the way for fault-tolerant (topological) quantum computing.

Tunable Geometric Fano Resonances in a Metal/Insulator Stack  

E-Print Network [OSTI]

A metal-insulator-metal-insulator stack is shown to have a Fano resonance in the angular domain. The metal/insulator stack consists of two interacting subsystems, a metallic waveguide mode and a surface plasmon mode, coupled by a finite layer metal film. The two modes in close spatial proximity interfere destructively resulting in level repulsion of two metal/insulator stack modes. By adding a coupling prism to momentum match the input EM field, the reflected field exhibits a geometric Fano resonance. Changes to the waveguide insulator permittivity and thickness are shown to tune the geometric Fano resonance. The geometric Fano resonance is also tuned by variations of the exterior insulator permittivity. At a given frequency, the geometric Fano resonance can be tuned to desired lineshape. In addition, this tunability allows for a geometric Fano resonance for any frequency in the visible range.

Möbius 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.

Holographic Metals and Insulators with Helical Symmetry  

E-Print Network [OSTI]

Homogeneous, zero temperature scaling solutions with Bianchi VII spatial geometry are constructed in Einstein-Maxwell-Dilaton theory. They correspond to quantum critical saddle points with helical symmetry at finite density. Assuming $AdS_{5}$ UV asymptotics, the small frequency/(temperature) dependence of the AC/(DC) electric conductivity along the director of the helix are computed. A large class of insulating and conducting anisotropic phases is found, as well as isotropic, metallic phases. Conduction can be dominated by dissipation due to weak breaking of translation symmetry or by a quantum critical current.

Novel metals and insulators from holography  

E-Print Network [OSTI]

Using simple holographic models in $D=4$ spacetime dimensions we construct black hole solutions dual to $d=3$ CFTs at finite charge density with a Q-lattice deformation. At zero temperature we find new ground state solutions with broken translation invariance, either in one or both spatial directions, which exhibit insulating or metallic behaviour depending on the parameters of the holographic theory. For low temperatures and small frequencies, the real part of the optical conductivity has a power-law behaviour, with the exponent determined by the ground state. We also obtain an expression for the the DC conductivity at finite temperature in terms of horizon data of the black hole solutions.

Topological insulators with SU(2) Landau levels  

E-Print Network [OSTI]

We construct continuum models of 3D and 4D topological insulators by coupling spin-1/2 fermions to an SU(2) background gauge field, which is equivalent to a spatially dependent spin-orbit coupling. Higher dimensional generalizations of flat Landau levels are obtained in the Landau-like gauge. The 2D helical Dirac modes with opposite helicities and 3D Weyl modes with opposite chiralities are spatially separated along the third and fourth dimensions, respectively. Stable 2D helical Fermi surfaces and 3D chiral Fermi surfaces appear on open boundaries, respectively. The charge pumping in 4D Landau level systems shows quantized 4D quantum Hall effect.

Sound insulation ratings—the STC revisited  

Science Journals Connector (OSTI)

About twenty years ago building authorities and their acoustical experts were faced with a confusing variety of schemes for rating the sound insulation of walls and floors. There was need for a definitive rating system that would digest the 16 transmission loss values that characterize a partition and produce a single number that would describe its sound insulation performance especially in respect to multi?family dwellings. Two standards committees ISO/TC 43 and ASTM E6 (now E33) began more or less together to develop a new improved rating system to fill this need. The product of these labors was what is known in North America as the ASTM sound transmission class (STC). This rating system was so successful that it was almost universally adopted—even in applications for which it was not intended. Despite the apparent success there is now increasing awareness of imperfections in the system. These are examined in light of accumulated data and experience to see whether the system could or should be improved by certain minor changes.

Development of Pre?Preg Ceramic Insulation for Superconducting Magnets  

Science Journals Connector (OSTI)

A new pre?impregnated (pre?preg) ceramic?based electrical insulation system capable of surviving high superconductor reaction temperatures has been developed for use in superconducting magnets. The use of Nb 3Sn superconductors holds great promise for increased magnet performance for high energy physics fusion and other applications. A robust cost?effective manufacturing process is critical to the successful implementation of these coils. Due to its embrittlement after the high temperature reaction cycle Nb 3Sn cable is usually insulated and wound into the coil prior to heat treatment. An earlier ceramic?based insulation system applied using wet?winding or vacuum impregnation has been successfully used in the “wind and react” fabrication process. Use of the new pre?preg system will further simplify the manufacturing process while improving control over the insulation properties. Pre?preg insulation offers several advantages including improved dimensional control of the insulation controllable and uniform fiber to matrix ratio and certainty that the insulation does not infiltrate the superconductor. This paper describes the pre?preg development process processing properties as well as insulation performance data at cryogenic temperatures.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (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.

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.

Design of Experiments Results for the Feedthru Insulator  

SciTech Connect (OSTI)

A design of experiments (DoE) was performed at Ceramtec to improve the yield of a cermet part known as the feedthru insulator. The factors chosen to be varied in this DoE were syringe orifice size, fill condition, solvent, and surfactant. These factors were chosen because of their anticipated effect on the cermet slurry and its consequences to the feedthru insulator in succeeding fabrication operations. Response variables to the DoE were chosen to be indirect indicators of production yield for the feedthru insulator. The solvent amount used to mix the cermet slurry had the greatest overall effect on the response variables. Based upon this DoE, there is the potential to improve the yield not only for the feedthru insulator but for other cermet parts as well. This report thoroughly documents the DoE and contains additional information regarding the feedthru insulator.

Chapter Four - Cryogenic Insulation Systems for LNG Industries  

Science Journals Connector (OSTI)

Abstract The market for liquefied natural gas (LNG) is growing faster than any other market for energy resources. Since LNG is normally carried by ship at -163°C, the functional requirements of a ship carrying LNG include cryogenic reliability due to thermal cyclic stresses and high thermal insulation performance for safe and efficient transportation of LNG. In order to guarantee the LNG cold temperature around -160°C, high-quality insulation installation in accordance with strict specifications is essential. Cryogenic insulation restricts the inflow of atmospheric heat into the pipe or process equipment, keeping the liquid cold and allowing it to retain its form. This chapter covers fundamentals for thermal insulation for various thermal insulation materials in LNG industries.

Development of microwave foaming method for phenolic insulation foams  

Science Journals Connector (OSTI)

Many types of foams are used for thermal insulation in building, frozen food industries and LNG containment systems. Low thermal conductivity, low density and low flammability are required for thermal insulation. Among many foams, phenolic foams are preferred for thermal insulation due to its lower flammability and lower gas generation than any other polymer insulation foams. However, it takes long time to manufacture large size phenolic foams and the environmental regulation limits the use of blowing agents. Urethane foams and polystyrene foams are widely used in spite of their high flammability and toxic gas generation because conventional phenolic foams usually have higher thermal conductivity than expected. In this work, a foaming method for the resole-type phenolic foams was developed using microwave and air instead of blowing agents, and its thermal and mechanical properties were measured. From the measured results, it was found that the phenolic foams developed had low thermal conductivity and low density suitable for insulation foams.

Superconductor-insulator Transition in La2-xSrxCuO4 at the Pair Quantum Resistance  

SciTech Connect (OSTI)

High-temperature superconductivity in copper oxides arises when a parent insulator compound is doped beyond some critical concentration; what exactly happens at this superconductor-insulator transition is a key open question. The cleanest approach is to tune the carrier density using the electric field effect; for example, it was learned in this way that weak electron localization transforms superconducting SrTiO{sub 3} into a Fermi-glass insulator. But in the copper oxides this has been a long-standing technical challenge, because perfect ultrathin films and huge local fields (>10{sup 9} Vm{sup -1}) are needed. Recently, such fields have been obtained using electrolytes or ionic liquids in the electric double-layer transistor configuration. Here we report synthesis of epitaxial films of La{sub 2-x}Sr{sub x}CuO{sub 4} that are one unit cell thick, and fabrication of double-layer transistors. Very large fields and induced changes in surface carrier density enable shifts in the critical temperature by up to 30 K. Hundreds of resistance versus temperature and carrier density curves were recorded and shown to collapse onto a single function, as predicted for a two-dimensional superconductor-insulator transition. The observed critical resistance is precisely the quantum resistance for pairs, R{sub Q} = h/(2e) = 6.45 k{Omega}, suggestive of a phase transition driven by quantum phase fluctuations, and Cooper pair (de)localization.

Strong side of weak topological insulators  

Science Journals Connector (OSTI)

Three-dimensional topological insulators are classified into “strong” (STI) and “weak” (WTI) according to the nature of their surface states. While the surface states of the STI are topologically protected from localization, this does not hold for the WTI. In this work, we show that the surface states of the WTI are actually protected from any random perturbation that does not break time-reversal symmetry, and does not close the bulk energy gap. Consequently, the conductivity of metallic surfaces in the clean system remains finite even in the presence of strong disorder of this type. In the weak disorder limit, the surfaces are found to be perfect metals, and strong surface disorder only acts to push the metallic surfaces inwards. We find that the WTI differs from the STI primarily in its anisotropy, and that the anisotropy is not a sign of its weakness but rather of its richness.

13 - Aerogel materials for insulation in buildings  

Science Journals Connector (OSTI)

Abstract: Aerogel materials have recently received much attention since they give many exciting applications in a wide range of areas. This chapter highlights the processing of these materials, the resulting physicochemical properties and their applications. Thus, fundamental understandings in the techniques for processing of aerogel materials including conventional drying, supercritical drying, freeze-drying, ambient-pressure drying with regards to material density and void size distribution, thermal conductivity, optical and acoustic properties are provided. In addition, a number of chemical post-treatments for surface engineering of aerogel materials are included. Finally, potentially new applications of using these materials as thermal insulation for building, optical sensor, space dust collector and catalysis are discussed.

CFC alternatives for thermal insulation foams  

Science Journals Connector (OSTI)

Low density polymeric foam material expanded with chlorofluorocarbon (CFC) blowing agents have found widespread use as highly efficient thermal insulation materials in the construction, refrigeration appliance and transportation industries. The advent of regulations which are reducing the production and consumption of the fully halogenated \\{CFCs\\} for environmental reasons has prompted the development of environmentally acceptable substitutes for the CFC blowing agents. This paper summarizes the physical properties and performance of the leading alternatives for CFC-11, which is used to expand rigid polyurethane and polyisocyanurate foams, and the leading alternatives for CFC-12 which is used to expand extruded polystyrene board foam. Although the alternatives, HCFC-123 and HCFC-141b for CFC-11 and HCFC-142b and HCFC-124 for CFC-12, are not perfect matches from the performance viewpoint, they represent the optimum choice given the constraints on environmental acceptability, toxicity, flammability and performance.

Analysis and testing of multilayer and aerogel insulation configurations  

SciTech Connect (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.

Gas Fills Gas Fills Why use a gas fill? An improvement that can be made to the thermal performance of insulating glazing units is to reduce the conductance of the air space between the layers. Originally, the space was filled with air or flushed with dry nitrogen just prior to sealing. In a sealed-glass insulating unit, air currents between the two panes of glazing carry heat to the top of the unit along the inner pane and settle down the outer pane into cold pools at the bottom. Filling the space with a less conductive, more viscous, or slow-moving gas minimizes the convection currents within the space, reducing conduction through the gas and the overall heat transfer between the interior and exterior.

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.

Effect of Deep Traps on the Barrier Heights of Metal-Insulator-Metal Tunnel Junctions  

Science Journals Connector (OSTI)

It is shown that the potential barrier ?max in a thin-film metal-insulator-metal system increases rapidly with increasing insulator thickness when electrons are immobilized in deep traps in the insulator, and at low voltage biases d?maxdV is independent of the insulator parameters. This effect may be an explanation of the observations of Lewicki and Mead.

Carpe Diem: Install Insulated Roman Shades Carpe Diem: Install Insulated Roman Shades Carpe Diem: Install Insulated Roman Shades March 16, 2010 - 11:44am Addthis John Lippert As I mentioned in yesterday's blog, I had insulated window quilts installed on most of my home's windows. I should have bought window quilts for all of our windows, but I refrained from doing so on two downstairs windows to save money (which, in the long run, I didn't). There were window shades already there; they didn't do much from a thermal perspective, but they did provide privacy and room darkening. Well, they need to be replaced now, and I'm looking again at high efficiency thermal window shades. This time I'm considering thermal Roman shades.

Homotopy Theory of Strong and Weak Topological Insulators  

E-Print Network [OSTI]

We use homotopy theory to extend the notion of strong and weak topological insulators to the non-stable regime (low numbers of occupied/empty energy bands). We show that for strong topological insulators in d spatial dimensions to be "truly d-dimensional", i.e. not realizable by stacking lower-dimensional insulators, a more restrictive definition of "strong" is required. However, this does not exclude weak topological insulators from being "truly d-dimensional", which we demonstrate by an example. Additionally, we prove some useful technical results, including the homotopy theoretic derivation of the factorization of invariants over the torus into invariants over spheres in the stable regime, as well as the rigorous justification of replacing $T^d$ by $S^d$ and $T^{d_k}\\times S^{d_x}$ by $S^{d_k+d_x}$ as is common in the current literature.

Identification of building applications for a variable-conductance insulation  

SciTech Connect (OSTI)

Recent experiments have confirmed the feasibility of controllable, reversible disabling of a vacuum insulation panel, which may result in the development of energy-efficient building envelope components. These components could extend the managed energy exchange through the building envelope from about 30% (typical with fenestration systems in commercial buildings), to as much as 90% of the gross wall and roof areas. Further investigation will be required to optimized the thermal response and the magnitude of the R-value swing (from a difference between insulating and conducting insulating values of 4 to as high as a factor of 100). The potential for energy reduction by using the variable-conductance insulation in the building envelope is discussed, and other potential building applications are mentioned.

Design and analysis of SMES-ETM electrical insulation  

SciTech Connect (OSTI)

The mechanical design and the electrical field analysis of the Ebasco/Westinghouse SMES-ETM coil electrical insulation system are presented. The electrical insulation design of the coil includes the turn to turn, layer to layer, and between the coil to the wall of the liquid helium vessel of the cryostat. A finite element analysis code (WEMAP) was used to obtain detailed electrical field plots of the high electrically stressed regions of the coil. These analytical results were used in conjunction with the experimental data of dielectric breakdown, available in the literature or obtained by in-house testing, to determine the optimum configuration and materials of the insulation spacers. An adequate design safety factor between the insulation capability and the maximum operating electrical stress was adopted to ensure the design integrity under all operating conditions and to allow for the uncertainties of the experimental dielectric breakdown data.

9 - Thermoset insulation materials in appliances, buildings and other applications  

Science Journals Connector (OSTI)

Abstract: Thermoset foam products are widely used for many technical insulation applications. They offer superior thermal insulation, a very favorable strength-to-weight ratio, and durability in a broad range of service conditions. Furthermore, fabrication technology is eased by the processing of a liquid reaction mixture and the auto-adhesive bond of reacting foam to most common substrates and facings materials. Polyurethane rigid foam is the material of choice for the whole cold-chain insulation industry, from food-processing, storage and transportation, to retailers and fridges at home. Polyurethane products are also largely used for the thermal insulations of buildings and for heat-management in pipelines and hot-water tanks. Phenolic foams find applications in some specific segments, thanks to their excellent fire and smoke behavior characteristics.

Linear particle accelerator with seal structure between electrodes and insulators  

DOE Patents [OSTI]

An electrostatic linear accelerator includes an electrode stack comprised of primary electrodes formed or Kovar and supported by annular glass insulators having the same thermal expansion rate as the electrodes. Each glass insulator is provided with a pair of fused-in Kovar ring inserts which are bonded to the electrodes. Each electrode is designed to define a concavo-convex particle trap so that secondary charged particles generated within the accelerated beam area cannot reach the inner surface of an insulator. Each insulator has a generated inner surface profile which is so configured that the electrical field at this surface contains no significant tangential component. A spark gap trigger assembly is provided, which energizes spark gaps protecting the electrodes affected by over voltage to prevent excessive energy dissipation in the electrode stack.

Tuning of the Metal-Insulator Transition via Alkali Adsorption  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Tuning of the Metal-Insulator Tuning of the Metal-Insulator Transition via Alkali Adsorption Tuning of the Metal-Insulator Transition via Alkali Adsorption Print Wednesday, 29 March 2006 00:00 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.

Thermal Performance of Exterior Insulation and Finish Systems Containing Vacuum Insulation Panels  

SciTech Connect (OSTI)

A high-performance wall system is under development to improve wall thermal performance to a level of U-factor of 0.19 W/(m2 K) (R-30 [h ft2 F]/Btu) in a standard wall thickness by incorporating vacuum insulation panels (VIPs) into an exterior insulation finish system (EIFS). Such a system would be applicable to new construction and will offer a solution to more challenging retrofit situations as well. Multiple design options were considered to balance the need to protect theVIPs during construction and building operation, while minimizing heat transfer through the wall system. The results reported here encompass an indepth assessment of potential system performances including thermal modeling, detailed laboratory measurements under controlled conditions on the component, and system levels according to ASTM C518 (ASTM 2010). The results demonstrate the importance of maximizing the VIP coverage over the wall face. The results also reveal the impact of both the design and execution of system details, such as the joints between adjacent VIPs. The test results include an explicit modeled evaluation of the system performance in a clear wall.

Flexible, reusable fiberglass insulation tailored to fit valves, heat exchangers  

SciTech Connect (OSTI)

About 120,000 bbl/day of crude oil are refined into gasoline at the Marathon Petroleum refinery in Robinson, IL. Built in the early part of the century, the Robinson refinery has been continually updated and modernized in response to improving technology. To control heat loss on some of the unusually shaped and previously uninsulated process equipment, Marathon engineering personnel initiated a program to systematically evaluate and insulate these pieces of equipment. Primarily, over 500 valves and heat exchanger heads were losing heat which had been estimated to cost hundreds of thousands of dollars per year. The plant performed on-site evaluations of several types of removable insulation covers. The primary differences and deciding factors were in construction detail - particularly in the fasteners. Marathon chose lace-up fastening insulation covers because plant evaluation found them to be the best. Also the manufacturer agreed to provide tailor-made covers for all of the valves and heat exchanger heads. Service from the manufacturer through an insulation contractor located in Robinson was also a plus. The local contractor, working in conjunction with the manufacturer, conducted an in-plant survey that confirmed the already mentioned heat loss cost in the $100,000s range. It was also determined that an equipment temperature somewhere between 150 and 200/sup 0/F was the lowest temperature at which to economically install insulation. Marathon has been pleased with the performance of the insulation covers which reduce heat loss and, as an incidental benefit, provide personnel safety from hot surfaces. An important benefit has been the removability and reusability of the insulation, particularly advantageous on valves and heat exchangers the require frequent access.

Cellular glass insulation keeps liquefied gas from vaporizing  

SciTech Connect (OSTI)

The North West Shelf Project, located on the Burrup Peninsula in Western Australia, supplies much of that vast state with natural gas for domestic and industrial applications. Some of the gas is also exported to Japan as liquefied natural gas (LNG). While awaiting shipment to Japan, the LNG is stored at {minus}322 F in four storage tanks, each with a capacity of 2.5 million ft{sup 3}. When Woodside Offshore Petroleum Pty Ltd., operator of the LNG facility, selected insulation material for the storage tanks, it went in search of a material with more than just insulating value. Since the insulation is installed inside the tanks, it must be able to resist wicking or absorbing the LNG. Also, it had to have sufficient strength to withstand the weight of the 2.5 million ft{sup 3} of LNG without being crushed or losing its insulting properties. And, as a safety precaution, the selected materials should neither burn nor support combustion. Ultimately, Woodside selected a cellular glass insulation called Foamglas, from Pittsburgh Corning Corp., that met all the performance criteria and was cost competitive with the lesser-performing alternatives. Foamglas is produced from strong, inert borosilicate glass. Its insulating capability is provided by the tiny, closed cells of air encapsulated within the foam-like structure of the glass. Since the cells are closed,neither liquid nor vapor can enter the structure of the insulation. The inert glass itself will not absorb or react with LNG, nor will it burn or support a fire. The cellular structure provides effective insulation in both not and cold applications, and offers a fire barrier.

Performance of Thermal Insulation Containing Microencapsulated Phase Change Material  

SciTech Connect (OSTI)

The objective of this study is dynamic thermal performance microencapsulated phase change material (PCM) blended with loose-fill cellulose insulation. Dynamic hot-box testing and heat-flux measurements have been made for loose-fill cellulose insulation with and without uniformly distributed microencapsulated PCM. The heat flux measurements were made with a heat-flow-meter (HFM) apparatus built in accordance with ASTM C 518. Data were obtained for 1.6 lb{sub m}/ft{sup 3} cellulose insulation containing 0 to 40 wt% PCM. Heat-flux data resulting from a rapid increase in the temperature on one side of a test specimen initially at uniform temperature were analyzed to access the effect of PCM on total heat flow. The heat flux was affected by the PCM for about 100 minutes after the temperature increase. The total heat flow during this initial period decreased linearly with PCM content from 6.5 Btu/ft{sup 2} at 0% PCM to 0.89 Btu/ft{sup 2} for 40 wt% PCM. The cellulose insulation with PCM discharged heat faster than the untreated cellulose when the hot-side temperature of the test specimen was reduced. In addition, hot-box apparatus built in accordance with ASTM C 1363 was utilized for dynamic hot-box testing of a wood stud wall assembly containing PCM-enhanced cellulose insulation. Experimental data obtained for wood-frame wall cavities containing cellulose insulation with PCM was compared with results obtained from cavities containing only cellulose insulation.

Supporting documentation for the 1997 revision to the DOE Insulation Fact Sheet  

SciTech Connect (OSTI)

The Department of Energy (DOE) Insulation Fact Sheet has been revised to reflect developments in energy conservation technology and the insulation market. A nationwide insulation cost survey was made by polling insulation contractors and builders, and the results are reported here. These costs, along with regional weather data, regional fuel costs, and fuel-specific system efficiencies were used to produce recommended insulation levels for new and existing houses. This report contains all of the methodology, algorithms, assumptions, references, and data resources that were used to produce the 1997 DOE Insulation Fact Sheet.

Optimal gap width for double and triple glazing systems Optimal gap width for double and triple glazing systems Glazing systems in the US are commonly designed with a 1/2 " (12.7 mm) gap. The optimal gap width depends on many factors, such as gas fill (air, argon, krypton), the use of Low-e coatings, the environmental conditions (temperature difference across the window), and the calculation standard used. NFRC standard conditions are -18 C (-0.4 F) outside, and 21 C (69.8 F) inside. The calculation standard used in the US is based on the ISO 15099 standard. European standard conditions are 0 C (32 F) outside, and 20 C (68 F) inside. The calculation standard is based on the EN 673 standard. A number of common glazing configurations both with and without Low-e coatings, and with a variety of gas fills were evaluated using both the North American NFRC standard and the European EN 673 standard. All results were calculated using WINDOW 6.3 from LBNL. All IGU's (Insulated Glazing Units) have a standard height of 1 meter.

A COMPARISON OF THE COMMUNITY PLANNING IMPLICATIONS FOR PASSIVE SOLAR, EARTH SHELTERED AND CONVENTIONAL HIGHLY INSULATED HOUSING DEVELOPMENTS  

Science Journals Connector (OSTI)

ABSTRACT Earth sheltered, passive solar and conventional highly-insulated houses have large variations in their need for solar exposure to maintain a high energy efficiency. They also have inherent implications for the minimum spacing of units under various assumed site conditions. The effect of full solar exposure on maximum densities of prototypical earth sheltered and solar developments is presented and compared to non-solar conventional construction. The effect of ground slope angles on the densities attainable is also included in the discussion.

Development of a Diehard GEM using PTFE insulator substrate  

E-Print Network [OSTI]

We have developed the gas electron multiplier (GEM) using polytetrafluoroethylene (PTFE) insulator substrate (PTFE-GEM). Carbonization on insulator layer by discharges shorts the GEM electrodes, causing permanent breakdown. Since PTFE is hard to be carbonized against arc discharges, PTFE-GEM is expected to be robust against breakdown. Gains as high as 2.6x10^4 were achieved with PTFE-GEM (50 um thick) in Ar/CO2 = 70%/30% gas mixture at V_GEM = 730V. PTFE-GEM never showed a permanent breakdown even after suffering more than 40000 times discharges during the experiment. The result demonstrates that PTFE-GEM is really robust against discharges. We conclude that PTFE is an excellent insulator material for the GEM productions.

Quantum Capillary Waves at the Superfluid—Mott-Insulator Interface  

Science Journals Connector (OSTI)

We discuss quantum fluctuations of the interface between a superfluid and a Mott-insulating state of ultracold atoms in a trap. The fluctuations of the boundary are due to a new type of surface modes, whose spectrum is similar—but not identical—to classical capillary waves. The corresponding quantum capillary length sets the scale for the penetration of the superfluid into the Mott-insulating regime by the proximity effect and may be on the order of several lattice spacings. It determines the typical magnitude of the interface width due to quantum fluctuations, which may be inferred from single-site imaging of ultracold atoms in an optical lattice.

Arasteh, Bjørn Petter Jelle, and Howdy Goudey Journal Energy and Buildings Volume 43 Issue 10 Pagination 2583-2594 Date Published 10/2011 Keywords Fenestration, heat transfer modeling, thermal performance, thermal transmittance, u-factor, window frames Abstract The thermal performance of windows is important for energy efficient buildings. Windows typically account for about 30-50 percent of the transmission losses though the building envelope, even if their area fraction of the envelope is far less. The reason for this can be found by comparing the thermal transmittance (U-factor) of windows to the U-factor of their opaque counterparts (wall, roof and floor constructions). In well insulated buildings the U-factor of walls, roofs an floors can be between 0.1-0.2 W/(m2K). The best windows have U-values of about 0.7-1.0. It is therefore obvious that the U-factor of windows needs to be reduced, even though looking at the whole energy balance for windows (i.e. solar gains minus transmission losses) makes the picture more complex.

Field impact insulation class (FIIC)—A case study  

Science Journals Connector (OSTI)

Impactnoise in buildings constitutes a potentially serious problem because of the short duration high intensity sounds involved [U.S. Department of Housing and Urban Development Airborne Impact and Structure Borne Noise Chapter 7 (1967)]. Since 1974 the State of California has tried to manage this problem by instituting the California Noise Insulation Standards which require any multi?family dwelling to provide an impact insulation class (IIC) rating of 50 based on laboratory tests or a field impact insulation class (FIIC) rating of 45 based on field tests [Office of Noise Control California Noise Insulation Standards 1–7 (1988)]. Concern about the acceptability of floor ceiling assemblies is increasing due to increased awareness of the problem and larger numbers of people moving into apartments condominiums and townhomes throughout California. Western Electro?Acoustic Laboratory (WEAL) had the opportunity to witness the installation of floor ceiling assemblies in an apartment complex in Bakersfield California. Six different assemblies were tested to determine how the FIIC value changed when minor modifications were made to the standard floor ceiling assembly. WEAL will show the results of the field?tested assemblies and compare the data with typical laboratory results for similar constructions.

Crystal-symmetry preserving Wannier states for fractional Chern insulators  

Science Journals Connector (OSTI)

Recently, many numerical evidences of fractional Chern insulator, i.e., the fractional quantum Hall states on lattices, are proposed when a Chern band is partially filled. Some trial wave functions of fractional Chern insulators can be obtained by mapping the fractional quantum Hall wave functions defined in the continuum onto the lattice through the Wannier state representation [Phys. Rev. Lett. 107, 126803 (2011)] in which the single particle Landau orbits in the Landau levels are identified with the one-dimensional Wannier states of the Chern bands with Chern number C=1. However, this mapping generically breaks the lattice point group symmetry. In this paper we discuss a general approach of modifying the mapping to accommodate the lattice rotational symmetry. The wave functions constructed through this modified mapping should serve as better trial wave functions in the thermodynamical limit and on the rotationally invariant finite lattice. Also these wave functions will form a good basis for the construction of lattice symmetry preserving pseudopotential formalism for fractional Chern insulators. The focus of this paper shall be mainly on the C4 rotational symmetry of square lattices. Similar analysis can be straightforwardly generalized to triangular or hexagonal lattices with C6 symmetry. We also generalize the discussion to the lattice symmetry of fractional Chern insulators with high Chern number bands.

Insulator-metal transition on the triangular lattice  

Science Journals Connector (OSTI)

Mott insulators with a half-filled band of electrons on the triangular lattice have been recently studied in a variety of organic compounds. All of these compounds undergo transitions to metallic and/or superconducting states under moderate hydrostatic pressure. We describe the Mott insulator using its hypothetical proximity to a Z2 spin liquid of bosonic spinons. This spin liquid has quantum phase transitions to descendant confining states with Néel or valence bond solid order, and the insulator can be on either side of one of these transitions. We present a theory of fermionic charged excitations in these states and describe the route to metallic states with Fermi surfaces. We argue that an excitonic condensate can form near this insulator-metal transition due to the formation of charge neutral pairs of charge +e and charge ?e fermions. This condensate breaks the lattice space group symmetry, and we propose its onset as an explanation of a low temperature anomaly in ?-(ET)2Cu2(CN)3. We also describe the separate BCS instability of the metallic states to the pairing of like-charge fermions and the onset of superconductivity.

The Federal Trade Commission accusses Thermtron Products of overstating the R-value of its cellulose insulation and failing to substantiate its 50% energy savings claim. The case was settled out of court, with Thermtron paying a penalty and agreeing to make adjustments to dissatisfied customers. The company has since corrected its advertising and labeling. (DCK)

A New Route to Nanoscale Conducting Channels in Insulating Oxides  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

A New Route to Nanoscale Conducting Channels in Insulating Oxides Print A New Route to Nanoscale Conducting Channels in Insulating Oxides Print Two-dimensional electron gases (2DEGs)-narrow conducting channels at the surfaces and interfaces of semiconductor materials-are the bedrock of conventional electronics. The startling 2004 discovery that such 2DEGs could be engineered at the interface between two insulating transition-metal oxides, SrTiO3 and LaAlO3, initiated a worldwide effort to harness the functionality of oxide materials for advanced electronic applications. Now, an international collaboration working at the ALS has shown that the interface is not required. Using only intense synchrotron light, the group has been able to create and control 2DEGs at the bare surfaces of the insulating oxides SrTiO3 and KTaO3. As well as suggesting a potential methodology to spatially pattern 2DEGs in a wide variety of complex oxides, this discovery opens a new avenue for spectroscopic investigation of these novel electronic systems.
