AWNINGS IN RESIDENTIAL BUILDINGS

The Impact on Energy Use and Peak Demand can be significant. Awnings have advantages that contribute to more sustainable
buildings. Awnings result in energy savings by reducing direct solar gain through windows, making your home naturally cooler and more comfortable while lightening your air conditioning load. This also directly reduces the impact of global warming from greenhouse gas emissions.

ELECTRICITY SAVINGS

Peak electricity demand is reduced by awnings which potentially results in reduced mechanical equipment costs.

Reduced peak demand may also result in energy cost savings in the future if residential customers are charged higher rates during peak periods. Another outcome of peak demand reduction is the overall savings to utility companies and the public from a decreased need to build new generating capacity.

Cooling Energy Savings and Peak Demand Reduction

Tables 1 and 2 show the impact of awnings on reducing cooling energy and peak demand in twelve U.S. cities with different climates. The cities are listed starting with the lowest cooling energy use (Seattle) up to the highest (Phoenix). For each city, results are shown for two typical houses. The first house has windows equally distributed on all four orientations while the second house has 80 percent of the windows facing west (the case with the highest cooling energy use from heat gain). The results in Tables 1 and 2 represent the best case for savings when awnings are applied to clear double-glazed windows and operated seasonally (details appear in the full report).
