Abstract
Windows bring light, warmth, and beauty into buildings and can give a feeling of openness and space to living areas. They can also be major sources of heat loss in the winter and heat gain in the summer. An average home may lose 30 percent of its heat or air conditioning energy through its windows. Employing energy conservation techniques can decrease heat loss or gain. When choosing windows for a building, the usual decision criteria tend to be appearance and initial cost. But energy efficiency is also very important. FACTORS TO CONSIDER The type of window is always selected according to the region of the U.S. in terms of Heating Degree Days, Cooling Degree Days, and whether the breeze or wind is coming from the North, South, West or East side of the building (see Table 1). Selecting the correct window for the particular location can save on heating and cooling costs. Window selection should include a number of factors, such as the different types of glazing, low-emissivity
