IRLab Thermography  

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

IRLab Thermography Experiments IRLab Thermography Experiments The human eye can't see the heat that shines off of everyday objects. But with the help of infrared imagers, researchers can "see" and measure this heat which radiates from every surface. This data can produce images called thermograms that are based on the temperature of objects. Researchers Dariush Arasteh, Brent Griffith, Daniel Türler, Paul LaBerge, Howdy Goudey, and Christian Kohler of the Building Technologies Program have developed an Infrared Thermography Laboratory to measure and image the surface temperatures of windows and other insulated systems. This type of thermal testing has the advantage that large amounts of surface temperature data can be collected without disrupting the test situation. The data are collected as an image that allows for a quick understanding of the relative performance of various parts in the system.

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

This effect is even greater in low-conductance (highly insulating) windows which incorporate very low conductance glazings. Developing low-conductance window frames requires accurate simulation tools for product research and development.

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.

A First-Generation Prototype Dynamic Residential Window A First-Generation Prototype Dynamic Residential Window Title A First-Generation Prototype Dynamic Residential Window Publication Type Report LBNL Report Number LBNL-56075 Year of Publication 2004 Authors Kohler, Christian, Howdy Goudey, and Dariush K. Arasteh Call Number LBNL-56075 Abstract We present the concept for a smart highly efficient dynamic window that maximizes solar heat gain during the heating season and minimizes solar heat gain during the cooling season in residential buildings. We describe a prototype dynamic window that relies on an internal shade, which deploys automatically in response to solar radiation and temperature. This prototype was built at Lawrence Berkeley National Laboratory from commercially available off-the-shelf components. It is a stand-alone, standard-size product, so it can be easily installed in place of standard window products. Our design shows promise for near-term commercialization. Improving thermal performance of this prototype by incorporating commercially available highly efficient glazing technologies could result in the first window that could be suitable for use in zero-energy homes. The units predictable deployment of shading could help capture energy savings that are not possible with manual shading. Installation of dynamically shaded windows in the field will allow researchers to better quantify the energy effects of shades, which could lead to increased efficiency in the sizing of heating, ventilation, and air conditioning equipment for residences.

Arasteh, and Dragan C. Curcija Journal Energy and Buildings Volume 54 Issue November 2012 Pagination 453-460 Date Published 11/2012 Keywords concave, convex, deflection, field test, gap, insulating glass unit, thermal performance, thermal transmittance, u-factor Abstract This study examines the thermal performance impact of center-of-glass (COG) deflections in double- and triple-pane insulating glass units (IGUs) installed at several locations throughout the US. Deflection was measured during summer and winter temperatures; the results show that outdoor temperature variations can be represented a linear change in COG gap width in double- and triple-pane IGUs within the temperature ranges measured. However, the summer-winter temperature-induced deflection is similar in magnitude to the observed spread in COG deflection of similar units at the same temperature, which suggests that factors other than temperature are of equal importance in determining the in-situ deflection of windows. The effect of deflection on thermal performance depends on the IGU's designed gap. Units constructed with smaller-than-optimal gaps often exhibit significant U-factor change due to temperature-induced reduction in gap width. This effect is particularly problematic in high-performance triple glazing where small gap dimension changes can have a large impact on performance.

Fenestration of Today and Tomorrow: A State-of-the-Art Review and Future

Fenestration of Today and Tomorrow: A State-of-the-Art Review and Future Fenestration of Today and Tomorrow: A State-of-the-Art Review and Future Research Opportunities Title Fenestration of Today and Tomorrow: A State-of-the-Art Review and Future Research Opportunities Publication Type Journal Article LBNL Report Number LBNL-5304E Year of Publication 2011 Authors Jelle, Bjørn Petter, Andrew Hynd, Arlid Gustavsen, Dariush K. Arasteh, Howdy Goudey, and Robert Hart Journal Solar Energy Materials and Solar Cells Volume 96 Start Page 1 Pagination 1-28 Date Published 01/2012 Keywords Fenestration, Low-e, Multilayer glazing, Smart window, Solar cell glazing, Vacuum glazing Abstract Fenestration of today is continuously being developed into the fenestration of tomorrow, hence offering a steadily increase of daylight and solar energy utilization and control, and at the same time providing a necessary climate screen with a satisfactory thermal comfort. Within this work a state of the art market review of the best performing fenestration products has been carried out, along with an overview of possible future research opportunities for the fenestration industry. The focus of the market review was low thermal transmittance (U-value). The lowest centre of glass Ug-values found was 0.28 W/(m2K) and 0.30 W/(m2K), which was from a suspended coating glazing product and an aerogel glazing product, respectively. However, the majority of high performance products found were triple glazed. The lowest frame U-value was 0.61 W/(m2K). Vacuum glazing, smart windows, solar cell glazing, window frames, self cleaning glazing, low-emissivity coatings and spacers were also reviewed, thus also representing possibilities for controlling and harvesting the solar radiation energy. Currently, vacuum glazing, new spacer materials and solutions, electrochromic windows and aerogel glazing seem to have the largest potential for improving the thermal performance and daylight and solar properties in fenestration products. Aerogel glazing has the lowest potential U-values, ~ 0.1 W/(m2K), but requires further work to improve the visible transmittance. Electrochromic vaccum glazing and evacuated aerogel glazing are two vacuum related solutions which have a large potential. There may also be opportunities for completely new material innovations which could revolutionize the fenestration industry.

Dual Glazing vs. Single Pane Dual Glazing vs. Single Pane On the left is a normal double glazed window. On the right is a single pane window. The single pane window is only slightly warmer than the cold air behind it. The dual pane window is considerably warmer which indicates that less heat is flowing out through the window and that the indoor space will be more comfortable. The two windows here are being cooled on the back side with wind at 0°C (32°F). (The other thermograms in this series are taken with colder conditions on the back side so don't try to cross compare these pictures. Too much frost builds up on the single pane window to allow testing it at the temperatures used for the other images). For more information contact: Howdy Goudey Building Technologies Program

Hollow vs. Foam-Filled Vinyl Windows Hollow vs. Foam-Filled Vinyl Windows Hollow vs. Foam-filled Vinyl Windows (100K) These two windows are the same except for what is inside the vinyl frames. The frame on the left is hollow, while the frame on the right is filled with insulating foam. The units have the same insulated glazing unit, a superwindow with R-8 center of glass. The hollow window frame allows air to circulate inside the frame; this convective effect is observed by noticing the frame temperatures are cooler at the bottom than at the top. The foam-filled window doesnÌt show this effect. These windows are being cooled on the back side with wind at -15°C (5°F).

Window-Related Energy Consumption in the US Window-Related Energy Consumption in the US Residential and Commercial Building Stock Joshua Apte and Dariush Arasteh, Lawrence Berkeley National Laboratory LBNL-60146 Abstract We present a simple spreadsheet-based tool for estimating window-related energy consumption in the United States. Using available data on the properties of the installed US window stock, we estimate that windows are responsible for 2.15 quadrillion Btu (Quads) of heating energy consumption and 1.48 Quads of cooling energy consumption annually. We develop estimates of average U-factor and SHGC for current window sales. We estimate that a complete replacement of the installed window stock with these products would result in energy savings of approximately 1.2 quads. We demonstrate

Coupling Air Flow Models to Load/Energy Models and Implications for Coupling Air Flow Models to Load/Energy Models and Implications for Envelope Component Testing and Modeling Speaker(s): Brent Griffith Date: July 30, 2002 - 12:00pm Location: Bldg. 90 Seminar Host/Point of Contact: Dariush Arasteh Air models allow accounting for air temperature variations within a thermal zone or along the surface of an envelope component. A recently completed ASHRAE research project (RP-1222) produced a source code toolkit focused on coupling airflow models to load routines typical of whole building energy simulation. The two modeling domains are computed separately (and iteratively) with relevant temperature boundary conditions passed back and forth. One of the air models in the toolkit is a new contribution to crude/fast airflow modeling that is based on solving the Euler equation

Curcija Call Number LBNL-813E Abstract WINDOW 6 and THERM 6 Research Versions are software programs developed at Lawrence Berkeley National Laboratory (LBNL) for use by manufacturers, engineers, educators, students, architects, and others to determine the thermal and solar optical properties of glazing and window systems. WINDOW 6 and THERM 6 are significant updates to LBNL's WINDOW 5 and THERM 5 computer program because of the added capability to model complex glazing systems, such as windows with shading systems, in particular venetian blinds. Besides a specific model for venetian blinds and diffusing layers, WINDOW 6 also includes the generic ability to model any complex layer if the Transmittance and Reflectance are known as a function of incoming and outgoing angles.

State-of-the-Art Highly Insulating Window Frames - Research and Market State-of-the-Art Highly Insulating Window Frames - Research and Market Review Title State-of-the-Art Highly Insulating Window Frames - Research and Market Review Publication Type Report LBNL Report Number LBNL-1133E Year of Publication 2007 Authors Gustavsen, Arlid, Bjørn Petter Jelle, Dariush K. Arasteh, and Christian Kohler Call Number LBNL-1133E Abstract 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.

Connell, Stephen E. Selkowitz, and Dariush K. Arasteh Conference Name 10th Passive Solar Conference Date Published 10/1985 Conference Location Raleigh, NC Call Number LBL-20080 Abstract The use of daylighting to supplant electric light in office buildings offers substantial energy savings and peak electrical demand reductions. The benefits from electric lighting reductions can, however, be easily offset by increased cooling loads if solar gains are not controlled.sThe use of advanced glazing materials having optical switching propertiesscan facilitate solar control and, with proper design, maximize energy and cost benefits. The potential net annual performance of these materials, based on simulation studies using DOE-2.1C, are discussed insthis paper. Actively and passively controlled response functions aresanalyzed for the cooling-load-dominated climate of Lake Charles. The effects of advanced materials on net annual energy consumption, peak electrical demand, and chiller size are compared with those of conventional materials. The results demonstrate the importance of operable solar control to achieve energy-effective daylighting design. Advanced optical materials that provide the necessary level of control are shown to minimize peak electrical demand and electricity consumption.

WINDOW 4.0: Documentation of calculation procedures  

Science Conference Proceedings (OSTI)

WINDOW 4.0 is a publicly available IBM PC compatible computer program developed by the Building Technologies Group at the Lawrence Berkeley Laboratory for calculating the thermal and optical properties necessary for heat transfer analyses of fenestration products. This report explains the calculation methods used in WINDOW 4.0 and is meant as a tool for those interested in understanding the procedures contained in WINDOW 4.0. All the calculations are discussed in the International System of units (SI). WINDOW 4.0 is the latest in a series of programs released by the Lawrence Berkeley Laboratory. The WINDOW program has its roots in a paper detailing a method for calculating heat transfer through windows [Rubin, 1982]. WINDOW 4.0 replaces the widely used 3.1 version. Although WINDOW 4.0 is a major revision, many of the algorithms used in WINDOW 4.0 build upon those previously documented [Arasteh, 1989b], [Furler, 1991]. This report documents the calculations that are unchanged from WINDOW 3.1, as well as those calculations that are new to WINDOW 4.0. This report uses the organization of the WINDOW 4.0 program. Results displayed on a WINDOW 4.0 screen are discussed in a section describing that screen. In the conclusion the aspects of the calculation method currently slated for revision are discussed. A glossary of variables used throughout the report is found in Section 11.

Developing Low-Conductance Window Frames: Capabilities and Limitations of Developing Low-Conductance Window Frames: Capabilities and Limitations of Current Window Heat Transfer Design Tools Title Developing Low-Conductance Window Frames: Capabilities and Limitations of Current Window Heat Transfer Design Tools Publication Type Journal Article LBNL Report Number LBNL-1022E Year of Publication 2008 Authors Gustavsen, Arlid, Dariush K. Arasteh, Bjørn Petter Jelle, Dragan C. Curcija, and Christian Kohler Journal Journal of Building Physics Volume 32 Pagination 131-153 Call Number LBNL-1022E Abstract While window frames typically represent 20-30% of the overall window area, their impact on the total window heat transfer rates may be much larger. This effect is even greater in low-conductance (highly insulating) windows which incorporate very low conductance glazings. Developing low-conductance window frames requires accurate simulation tools for product research and development. Based on a literature review and an evaluation of current methods of modeling heat transfer through window frames, we conclude that current procedures specified in ISO standards are not sufficiently adequate for accurately evaluating heat transfer through the low-conductance frames.

Future Advanced Windows for Zero-Energy Homes

Future Advanced Windows for Zero-Energy Homes Future Advanced Windows for Zero-Energy Homes Title Future Advanced Windows for Zero-Energy Homes Publication Type Conference Paper LBNL Report Number LBNL-51913 Year of Publication 2002 Authors Apte, Joshua S., Dariush K. Arasteh, and Yu Joe Huang Conference Name ASHRAE Transactions Volume 109, pt 2 Date Published 06/2003 Conference Location Kansas City, MO Call Number LBNL-51913 Abstract Over the past 15 years, low-emissivity and other technological improvements have significantly improved the energy efficiency of windows sold in the United States. However, as interest increases in the concept of zero-energy homes-buildings that do not consume any nonrenewable or net energy from the utility grid-even today's highest-performance window products will not be sufficient. This simulation study compares today's typical residential windows, today's most efficient residential windows, and several options for advanced window technologies, including products with improved fixed or static properties and products with dynamic solar heat gain properties. Nine representative window products are examined in eight representative U.S. climates. Annual energy and peak demand impacts are investigated. We conclude that a new generation of window products is necessary for zero-energy homes if windows are not to be an energy drain on these homes. Windows with dynamic solar heat gain properties are found to offer significant potential in reducing energy use and peak demands in northern and central climates, while windows with very low (static) solar heat gain properties offer the most potential in southern climates.
