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 ... -
A Correlation to Quantify Convective Heat Transfer Between Vertical Window Glazings
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)Several correlations have been used in recent years for the purpose of calculating convective, centre-glass heat transfer rates across gas-filled interpane window cavities. These correlations are examined and their background ... -
High Performance Window Systems and their Effect on Perimeter Space Commercial Building Energy Performance
(University of Waterloo, 2010-09-29)In the quest for improving building energy efficiency raising the level of performance of the building enclosure has become critical. As the thermal performance of the building enclosure improves so does the overall energy ... -
Modelling and Optimization of an Airflow Window with Between-the-Panes Shading Device
(University of Waterloo, 2006)Abstract <br /> This thesis deals with the numerical investigation of the upper section of a building-integrated photovoltaic/thermal double-façade. The upper section consists of an airflow window with a between-the-panes ... -
Numerical Analysis of Natural Convection Heat Transfer for Windows with Porous Screening Material
(University of Waterloo, 2009-05-26)A numerical study of natural convection across a window cavity with an insect screen was performed in order to investigate the effects of changing several variables on the heat transfer through the system. A two-dimensional, ... -
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 study of insulated glazing unit surface temperature profiles using two-dimensional computer simulation
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1996)This paper describes one part of a collaborative research project, including both measurement and simulation studies, aimed at determining the surface temperature of a set of insulated glazing units (IGUs). In this study ... -
Summary and comparison of methods to calculate solar heat gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)Methods used to calculate the solar gain of windows (including center-glass, edge-glass, and frame) are examined and compared Particular attention is devoted to the public-domain computer programs VISION3 and WINDOW 4.1. ... -
Thermal Resistance of a Window with an Enclosed Venetian Blind: A Simplified Model
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)Solar gain has a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on 1-D models is available to accurately predict the thermal ... -
Thermal Resistance of a Window with an Enclosed Venetian Blind: Guarded Heater Plate Measurements
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)Window solar gain is known to have a strong influence on building energy consumption and peak cooling load. Venetian blinds are routinely used to control solar gain. Software based on one-dimensional models is available ... -
A two-dimensional numerical model for glazing system thermal analysis
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-08)A simple two-dimensional (2-D) numerical control volume formulation is presented that can be used to model heat transfer through a vertical insulated glazing unit. This model accounts for natural convection of the fill gas ...
