Savings Calculator

Follow the instructions in the form below to calculate your approximate savings after installation of Functional Art Thermal Insulated Window Treatments.

1. Enter the area of the windows you intend to cover with Functional Art Insulated Window Treatments
Area to be upgraded Square Feet

Area of each window =
width x height (inches)
divided by 144. For example, 30" (W) x 48" (H) = 1440 sq in, divided by 144 = 10 sq ft (calculate each window, then total)
2. Enter the average number of heating degree days for your location, or use the default value (accurate for most of western Massachusetts)
Heating Degree Days HDD (Fahrenheit) Help on finding Heating Degree Days for your area
3. Enter the current R-Value of the windows you intend to cover with Functional Art Insulated Window Treatments
Current R Value US R Value See our chart for help
New Total R Value US R Value Current R-Value + 6.39

$ Saving per year Dollars The dollar saving in fuel cost for the first year.
$ Saving for 10 years Dollars The dollar saving in fuel costs for the first 10 years, assuming a 10% increase in fuel cost each year.
Greenhouse Gas Reduction lbs per year If electricity is the fuel, it is assumed it is generated in a coal fired power plant.

Notes:

It should be noted that insulation also saves money on cooling bills, and these savings are NOT calculated by this calculator.

Greenhouse gas emissions are high for electricity because the electricity is assumed to be generated in a coal fired power plant.  Coal plants are only about 30% efficient, and coal is a very high Carbon fuel.  About 50% of the power generated in the US is from coal fired power plants -- these coal plants account for about 80% of all US electric power generation CO2 emissions.
