Benefits: Lower HVAC Costs
High-performance windows not only provide reduced annual heating and cooling
bills; they reduce the peak heating and cooling loads as well. This has benefits
for the homeowner, in that the size of the heating or cooling system may be
reduced, and it also benefits the electrical utilities, in that load factors are
reduced during the peak times in summer. Note: these peak loads were calculated using RESFEN for a typical 2000 sq ft house with 300 sq ft of window area located in Phoenix, Arizona. Source: Residential Windows by Carmody, Selkowitz, Arasteh and Heschong, 2000. |
