Estimated savings by insulating a basement
OK, I'm hoping you will all take a crack at this so I can compare your numbers to mine!
I need to estimate the energy savings that would be achieved from taking an uninsulated basement wall of a home in Spencer, Iowa and insulating it to a total R value of R13 using either XPS or spray foam that would would be framed and covered with drywall to meet code. Assume NO additional insulation in the stud cavities.
Here's the details of the home:
Ranch home, 1538 square feet of basement space. Total wall square feet is 1,288 sq ft.
Basement is conditioned.
Basement walls are bare concrete block, 8".
Heating degree days in 2010 were 8,047 (using degreedays.net, 65 degree baseline)
Customer heats with an electric furnace.
If you come up with a number, can you share HOW you arrived at it? Again, I want to compare to see if the calculator I am using is at all accurate. Thanks in advance for your help!
