A Simplified Analysis of Radiant Heat Loss Through Projecting Fenestration Products
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2001)
Current window analysis algorithms can deal with many features, including low-e coatings and substitute fill gases. These methods were developed for products with planar glazings. Results can be generated for projecting ...
Determining Off-Normal Solar Optical Properties of Insect Screens
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
Shading attachments may have a strong influence on solar gain. The determination of off-normal solar optical properties of individual layers of glazing/shading systems is required in order to estimate this solar gain, which ...
Calculating Center-Glass Performance Indices of Windows with a Diathermanous Layer
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)
The fenestration chapter of the 2005 ASHRAE Hand-book—Fundamentals (ASHRAE 2005) has long included methods for determining the U-factor and solar heat gain coef-ficient (SHGC), or window performance indices, using 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 ...
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 ...
Heat Transfer Analysis Of Windows With Venetian Blinds: A Comparative Study
(2007-06)
The potential to reduce building load and annual energy consumption is widely recognized in the use of shading devices to control solar gain. Consequently, the ability to include and model shading layers in complex glazing ...
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 ...
A Detailed Model to Determine the Effective Solar Optical Properties of Draperies
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)
Drapes have the potential to reduce peak cooling load and annual energy consumption because they can be used to control solar gain. Thus, the need to model a drapes in a glazing system analysis is important. A detailed ...
Heat Transfer Analysis of a Between-Panes Venetian Blind Using Effective Longwave Radiative Properties
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2004)
Center-glass thermal analysis programs based on one-dimensional models have proved to be exceptionally useful. Recently efforts have been made to extend the analysis to include venetian blinds. It is convenient to model ...
An Examination of Keyes Universal Chart: 50 Years Later
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2016-01)
From the late 1940's to the late 1960's, significant efforts were made by ASHVE and then ASHRAE to evaluate and quantify the impact of window shading. In the context of the now defunct Shading Coefficient, well known ...
