Calculating Center-Glass Performance Indices of Glazing Systems with Shading Devices
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)Building energy consumption and loads are strongly influ-enced by solar gain and heat transfer through the centre-glass area of windows. Methods have been devised to calculate the corresponding energy performance indices ... -
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 ... -
Determining Off-Normal Solar Optical Properties of Drapery Fabrics
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)The determination of off-normal solar optical properties of drapery fabrics is particularly useful in modelling the effective solar optical properties of pleated drapery. Special sample holders were designed and fabricated ... -
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 ... -
Determining Off-Normal Solar Optical Properties of Roller Blinds
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)Solar gain through fenestration constitutes a significant portion of peak cooling load and annual energy consumption in buildings. As such, any reduction in solar gain translates into savings associated with the cost of ... -
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 ... -
Improving Load Calculations for Fenestration with Shading Devices
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009-10)Activities and findings arising from ASHRAE Research Project 1311-RP are summarized. This project included three main goals, (a) development of models for pleated drapes, venetian blinds, roller blinds and insect screens, ... -
Methods for Calculating the Effective Solar-Optical Properties of a Venetian Blind Layer
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2005)Window solar gain can strongly influence building energy consumption, peak loads, and comfort. Shading devices are routinely used to control solar gain. The use of venetian blinds is particularly common. There is a strong ... -
Off-Normal Solar-Optical Performance of Pleated Drapery: Simulation versus Measurement
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2016-01)In recent years, significant advances have been made in modeling fenestration with shading attachments. Most shading devices have great potential for reducing both peak building cooling load and annual energy consumption ... -
A Simplified Method For Calculating The Effective Solar Optical Properties Of a Drapery
(2007-06)The use of draperies to control solar gain through windows is common in residential and commercial buildings and their potential for reduction of building peak load and annual energy consumption is recognized to be large. ... -
Simplified Solar Optical Calculations For Windows With Venetian Blinds
(2006)Solar gain through a window represents the most variable heat gain imposed on an indoor space. It is also likely to represent the largest heat gain of the indoor space. Shading devices like venetian blinds roller blinds ... -
Solar Absorption by Each Element in a Glazing/Shading Layer Array
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)Window solar gain can strongly influence building energy consumption and peak cooling load. Shading devices such as venetian blinds, roller blinds, and drapes are routinely used to control solar gain. There is a strong ... -
Solar Gain through Windows with Shading Devices: Simulation Versus Measurement
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2009)Shading devices offer a cost saving strategy in dynamically controlling solar gain through windows. As such, there is an ongoing effort to accurately quantify the thermal performance of shading devices. In the present ...
