: In an article you wrote that was in the Detroit Free Press on 10-18-09 you discussed the energy efficiency of our home . You listed a formula for figuring it out One of the factors was using my regions heating and cooling days. But I can not find that information anywhere . All of Michigans energy company websites know nothing of this term. Can you enlighten them?
It is "heating DEGREE days" and "cooling DEGREE days" to use, not just heating days and cooling days. Contact your local weather service or utility company to find out the total number for the period of your calculation.
