Effective U-values and Shading Coefficients of Preheat/Supply Air Glazing Systems
(1986-06)
Research is documented which makes use of a computer program called VISION, This computer program was developed specifically to provide a detailed analysis of heat transfer occurring in glazing systems. VISION was modified ...
Simulation And Measurement Of Windows With Metal Films Used In Conjunction With Teflon Inner Glazings
(1987-09)
Previous work has shown that highly infrared transparent plastic films are well suited for use as inner glazings when used in conjunction with a low emissivity coating. Thermal resistance measurements of a set of glazing ...
Calculating Window Solar Heat Gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-07)
Window design has been revolutionized-largely by the introduction of low emissivity (low-e) coatings and substitute fill gases. The large number of design options necessitates the use of computer simulation for development ...
Calculating the Solar Heat Gain of Window Frames
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)
It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ...
Determining Longwave Radiative Properties Of Flat Shading Materials
(2008-08)
Solar gain through fenestration has a significant impact on building peak load and annual energy consumption. Shading devices, attached to fenestration, offer a cost effective strategy in controlling solar gain. The ...
Overview of a Project to Determine the Surface Temperatures of Insulated Glazing Units: Thermographic Measurement and Two-Dimensional Simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)
A collaborative research project was undertaken to generate surface temperature profiles for the indoor side of seven different double and triple-glazed insulated glazing units exposed to the ASHRAE winter design condition. ...
A Simplified Numerical Method for Assessing the Condensation Resistance of Windows
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1998)
Methods have been established for calculating heat transfer in windows whereby a one-dimensional analysis is used for the center-glass area and a two-dimensional numerical calculation is used to model conduction in the ...
Calculating Center-Glass Performance Indices of Windows
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1998)
Building envelope performance is strongly influenced by solar gain and heat transfer through windows. The majority of this energy gain or loss passes through the center-glass area of the glazing system. Various methods ...
Glazing System U-Value Measurement Using a Guarded Heater Plate Apparatus
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1988)
Precise heat transfer measurements have been carried out during the last 20 years using a guarded heater plate apparatus. This apparatus has been adapted and used over the last several years to perform U-value measurements ...
Computer Simulation of Window Condensation Potential
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1998-12)
Condensation on windows creates obscured view, can cause building damage, and may lead to mold growth and poor indoor air quality. The Canadian Standards Association (CSA) has developed new procedures to evaluate window ...
