After doing a blower door test and studying the building, you determine that the natural air changes is approximately 0.4 ACHn. If the house is 21728.9 Ft3 and the building is in a climate that has 3533.6 heating degree days, what would you approximate the total heating season energy loss to be? Assume a density of air as 0.075 lb/Ft^3. Assume the specific heat capacity is 0.24 BTU/(Ib X F)
