We’re getting ourselves ready to build some software to help predict whole house fan energy savings. In the meantime, I put together this spreadsheet, which I think is a pretty good approximation for the coastal areas of California.
|Potential Whole House Fan Energy Savings per Year for California|
|Input Energy cost||$0.24||Dollars per KWH|
|Application||High Speed Watts||Low Speed Watts||Energy Savings * (per Year)|
|* Assumptions are that the cooling season is 5 months, the WHF is run 10 hours/day, 40% use is at low speed, an average deltaT at night is 10Âº , and that all WHF cooling offsets AC use.|
