We had an energy audit done a couple of years ago on our 20 year old home. Basically, they hooked up a blower to the front door, and tested the amount of air leakage.
The written report suggested a number of improvements, most of which we did: new windows, doors, sealing attic hatches, etc. The total spent was around $15k.
Because there's a local government plan to cover some of the expenses, we had a follow up audit done.
The overall score from the follow up was exactly the same. This really baffles me, because I know in a couple of places (pre-repair) I could feel a breeze coming in, and the candle test showed it.
Will I actually get any savings from my new, expensive, energy-star compliant doors & windows?
