Window Replacement Solutions
Many energy retrofits focus on lighting, boilers or motors, but the full efficiency gains and energy savings from these retrofit measures cannot be realized with inefficient windows. Inefficient windows account for 25% of a typical building's heat load in cool climates and as much as 50% of the cooling load in warm climates. Window replacement can be done as a stand alone efficiency measure or as part of a deep energy retrofit.
