Leaky outlet boxes

Well essentially outlets and switch boxes are holes in your wall. inevitably a blower door test will reveal that there is leakage through the outlets. These can be sealed with foam or caulk. What I wanted to get at was this cool product that eliminates this problem. The Airfoil They have wall boxes and ceiling J-boxes Obviously these are mostly for new construction or extensive remodels but should be considered especially for exterior walls.

You foam the slots where the wires pass through and no more leak.

HERS II audits update

There are two providers that certify HERS raters and they are supposed to have an online registry for filing these ratings. This registry has to have very particular criteria to receive approval from the CEC. I was certified through CHEERS which did not manage to get their online registry together or up to the CEC dictates. There fore they can not provide the necessary service to us raters to do our job. Luckily the other provider CalCERTS stepped in and made some allowances to help the CHEERS raters get re-certified with CalCERTS. This is what I am doing; as of now I am certified for new construction and HVAC change outs. Dec 13, 2010 I start the training for the Whole House Energy Rater module which is equivalent to CHEERS existing homes except it is actually approved by the CEC. So I'll be official again soon but now I am still able to provide necessary paper work for getting permits.
