Energy and cost savings
of energy efficient replacement
windows
The following information is an example of energy and cost
savings for a cold climate on the East coast and a warmer climate of a
desert area in the Southwest United States.
Cold Climate Savings:
In cold climates were heating is significant; windows are a major source
of heat loss as well as condensation. Because of recent technological
developments in manufacturing windows, heat loss can be reduces as well
as air leakage. This has created warmer window surfaces, which reduces
the amount of condensation build up on windows.
Warm Climate Savings:
In warmer climates where cooling is significant, windows are source of
unwanted heat gain, by permitting solar heat into the home. Because of
recent technological developments in manufacturing windows, solar heat
gain can be reduced significantly, while still permitting in daylight
and clear visibly.
