Infrared Tells the Story
Before and After of Window Treatment for Comfort

Looking out the window through Climate Control Solar Blinds by Energy Savings 4 You.
Located in Maine U.S.A. Jan/2009, 13°F outside temperature.

Window A: Using an Infrared Gun to measure the heat escaping from both windows, the outside window glass temperature was 16.3°F.

Window B: The outside window glass temperature was 18.7°F

With the Climate Control Solar Blind installed on the inside of the window the reading was close to the wall temperature.
The window equipped with Solar Blind measured at (+)(spot 2) 64.4°F temperature.
This compared to the insulated (R 22) walls measured at (+)(spot 1) 67.3°F temperature.

The Building Envelope
Comparison of Window Treatments and Retrofit Options

What is the building envelope?

Your building's “shell” or “envelope” is made up of the windows, outside doors, walls, foundation, floor, roof, and skylights. The envelope is the barrier between the carefully controlled, temperate indoor environment in your building and the fluctuating and sometimes harsh outdoor temperatures. The envelope is also the selective filter which can be used the indoor temperature more comfortable, by allowing certain amounts of light, fresh air, heat, coolness and humidity to enter and leave.

If the envelope works well as a barrier and as a filter, you will use less energy in your lighting and HVAC (heating, ventilation, and air conditioning) systems to control the light, temperature, humidity and fresh air levels. So the job of the building envelope is to stabilize interior temperatures by blocking or reducing exterior temperatures or conditions from entering the building.

In the book “The Energy Efficiency Guide for Businesses, Industry, Government and Institutions”, Third Edition on their segment titled “Envelope”, the objectives to minimize energy losses are clearly stated.

These objectives are to: stop infiltration, reduce heat transfer, control humidity and control sunlight.

Since windows are usually the primary “weak point” in the building envelope, we will compare some window treatments and retrofit options. Keep in mind that usually the most important elements are to control sunlight and reduce radiant heat loss or gain. Also remember that up to 80% of all heat movement is radiance and most all windows and window coverings are not capable of managing radiant heat movement.

COMMENTS
Blinds, Shutters, Shades & Curtains YES NO NO NO Makes more shade but reduces natural light.
No real payback.
Window Film YES NO NO NO Darker tints make people feel coller, but can attract heat.
No real payback. Usually voids window warranty.
Solar Screens YES NO NO NO Not much benefit for cost with a limited life span. Limited payback.
Double Pane andTriple Pane Glass NO YES YES YES Lack insulating ability, a bad insulator. Minimal payback. Major expense ($50 a sq.ft.)
Climate Control Solar Blinds and Panels by Energy Savings 4 You YES YES YES YES The engineered solution, with the most comfort enhancement. Less than 4 year payback (typical). Long life span and UV protection.

When all the facts are considered, there is only one solution that addresses year around window issues – Climate Control Solar Blinds and Panels.
