Adding a Rainier Awning to your home keeps you from sweating over energy bills!
Sunny summer afternoons can turn your house into a sauna – but using a retractable awning blocks the sun from beating in during the afternoon hours, lowering the temperature without air conditioning. With your home a comfortable temperature and your electric bill lower, you can relax all summer.
How do we know this? We supported a research project overseen by the Professional Awning Manufacturers Association (PAMA) in which Lawrence Berkley National Laboratory conducted a research project using a simulation software program called RESFEN.
Here’s some background information about the project:
The annual energy performance figures shown below are for a typical (new construction) 2,000 square foot home with 300 square feet of window area (windows equally distributed on all four sides of the home).
The figures shown below are for savings when awnings are applied to clear double-glazed windows & operated seasonally.
There can be little or no peak demand savings from awnings in some hot, humid cities. This is due to climatic variations that influence whether peak demand is driven more by solar gain through windows, or by factors such as temperature and humidity.
