Energy efficient windows can substantially reduce the costs associated with heating and cooling. In climates that mainly require cooling, non-energy efficient windows can be a major source of unwanted heat gain. In recent years, low-E coatings that reject solar heat without darkening the glass have undergone a technological revolution. It is now possible to significantly reduce solar heat gain and improve comfort while providing clear views and daylight. Depending on the condition of the old windows in an existing home, the savings can be higher if window replacement leads to long-term air leakage reduction.
