    • Demonstration Of New ESP-R Capability For Quantifying The Energy Savings Potential Of Window Shading Devices 

      Wright, John L.; Kotey, Nathan Amon; Lomanowski, Bartosz (2009-06)
      Buildings with highly glazed facades and well insulated, air-tight envelopes result in interior spaces that are highly sensitive to solar gain. Solar gain through glazing is the largest and most variable gain in buildings ...
    • A Detailed Model to Determine the Effective Solar Optical Properties of Draperies 

      Kotey, Nathan Amon; Wright, John L.; Collins, Michael R. (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 Longwave Radiative Properties Of Flat Shading Materials 

      Kotey, Nathan Amon; Wright, John L.; Collins, Michael R. (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 ...
    • Determining Off-Normal Solar Optical Properties of Drapery Fabrics 

      Kotey, Nathan Amon; Collins, Michael R.; Wright, John L. (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 

      Wright, John L.; Collins, Michael R.; Kotey, Nathan Amon (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 

      Kotey, Nathan Amon; Wright, John L.; Collins, Michael R. (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 ...
    • Measurements and Models Related to Solar Optics in Windows with Shading Devices 

      Kotey, Nathan Amon (University of Waterloo, 2009-04-13)
      Shading devices 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 shading devices in a glazing system analysis is ...
    • A method for determining the effective longwave radiative properties of pleated draperies 

      Kotey, Nathan Amon; Wright, John L.; Collins, Michael R. (Taylor & Francis, 2011-10-01)
      Draperies, attached to fenestration, offer a cost-effective strategy in controlling solar gain since draperies have the potential to reduce building peak load and annual energy consumption. The performance of a drapery is ...
    • Off-normal solar optical property measurements using an integrating sphere 

      Collins, Michael R.; Wright, John L.; Kotey, Nathan Amon (Elsevier, 2012-01-01)
      Shading devices attached to windows can be used to control solar gain and hence reduce building peak load and annual energy consumption. The performance of a shading device in this regard is strongly dependent on its solar ...
    • A Simplified Method For Calculating The Effective Solar Optical Properties Of a Drapery 

      Kotey, Nathan Amon; Wright, John L.; Collins, Michael R. (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 

      Wright, John L.; Kotey, Nathan Amon (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 

      Wright, John L.; Kotey, Nathan Amon (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 

      Wright, John L.; Kotey, Nathan Amon; Barnaby, Charles S.; Collins, Michael R. (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 ...
