The purpose for windows is to provide natural light, natural ventilation, and views to the outside. The benefits of high performance windows allows for Energy & Cost Savings, Improved Comfort, Less Condensation, Increased Light & View, Reduced Fading, and Lower heating and cooling Costs.Design Considerations
Windows are a complex and interesting element in residential design. New window products and technologies have changed the performance of windows in a radical way. Issues such as climate, orientation, shading, and window area all effect the energy performance, but human factor issues such as access to fresh air, daylight, and natural views impact the comfort of a home.Understanding Performance
Heat flows through a window assembly in three ways: conduction, convection and radiation. When these basic mechanisms of heat transfer are applied to the performance of windows, they interact in complex ways. Three energy performance characteristics of windows are used to portray how energy is transferred and are the basis for how energy performance is quantified. Insulating value. When there is a temperature difference between inside and outside, heat is lost or gained through the window frame and glazing by the combined effects of conduction, convection, and radiation. This is indicated in terms of the U-factor of a window assembly.Heat gain from solar radiation. Regardless of outside temperature, heat can be gained through windows by direct or indirect solar radiation. The ability to control this heat gain through windows is measured in terms of the Solar Heat Gain Coefficient (SHGC) of the window.
Infiltration. Heat loss and gain also occur by Air Leakage through cracks in the window assembly. This effect is measured in terms of the amount of air (cubic feet or cubic meters per minute) that passes through a unit area of window (square foot or square meter) under given pressure conditions. In reality, infiltration varies slightly with wind-driven and temperature-driven pressure changes.
