Benefits: Savings

Cooling and Heating Savings -- Low-E coatings, gas fills, and insulating spacers and frames can significantly reduce winter heat loss and summer heat gain.

Cooling Season Savings

In climates that mainly require cooling, windows have represented a major source of unwanted heat gain. It is now possible to significantly reduce solar heat gain and improve comfort while providing clear views and daylight.

Heating Season Savings

Climates further north in Texas with a more significant heating season, typically have windows which represent a major source of unwanted heat loss, discomfort, and condensation problems. It is now possible to have lower heat loss, less air leakage, and warmer window surfaces that improve comfort and minimize condensation.

Lower Mechanical Equipment Costs

Using windows that significantly reduce solar heat gain also means that cooling equipment costs may be reduced. By reducing the peak heating and cooling loads, heating and cooling systems can often produce further savings through a reduction in system size.
