Cut Cooling Costs
Rainier Screens battle the sun to keep you from sweating over energy bills!
The sun can act as a furnace for your home – but without an “OFF” switch. Instead, many of us turn “ON” the air conditioners, increasing monthly utility bills.
Exterior screens can help stop the sun’s rays from striking your windows, thus reducing heat transfer and keeping your home cooler. You’ll still have the option to take advantage of the sun’s warmth – just raise your screens to help heat your home.
Now that’s solar power!
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.
* Unfortunately, a study specifically about exterior screens and energy savings hasn’t been conducted yet, but there’s good news: exterior screens are just awnings without arms! Screens cover windows vertically and awnings cover them horizontally, so the findings from the research done with awnings still give you a good idea of the energy savings you can achieve with exterior screens.
