Energy Efficency
Josh 2004 Happy

So, the blower door test was run on our house today. Our ACH was 0.39, which means 39% of our air exchanges with the outside, per hour. Energy Star rating is 33% or less, and average for our age of house is around 50%.

Also, our vents leak 0.2% to 0.7%, and target is under 2.2%.

Most of the downstairs windows and doors have had the caulk redone with long-life, elastomeric goodness.

The overall air leaks of our entire house combined would be a square hole 11" x 11", and the yearly cost of that leaking is $112.

In other words, our house is doing great as far as energy efficiency goes.

I still plan to
* finish recaulking windows (upstairs, plus the office downstairs, plus the patio door)
* get radiant barrier and a ridge vent after the roof is redone
* Look into more blow-in insulation for Max's bedroom wall
* Look into topping up the attic insulation
* Look into insulating the plenum that lets garage air and heat into the upstairs sidewall.
