The Washington State Department of Commerce has released, "Evergreen Sustainable Development Standard Version 3.0." Below are notes as related to residential airtightness testing:

Section 5.11: Airchange on rehab gets 3 pts for 7 ACH and 7 pts for 5 ACH.  This could be difficult in some types of houses. Key step, is to find all the attic leaks around plumbing stack vents and chimneys that can be sealed off with foamboard, foam and sheet metal for chimneys. Then wiring penetrations and pot lights that must all be replaced with sealed LED units to save on leakage and  power. This work is most easily done by removing the insulation which will allow the tops of all wals to be sealed between the 2x4 and sheetrock.  All open joist ends must be blocked and sealed. Then look at joist spaces in the basement that should all be foamed. DOE has a Bypass Guide

Congratulations to Craig Senglin, winner of Retrotec’s $2,000 Equipment Giveaway at RESNET!

Retrotec’s $2,000 Equipment Giveaway celebrated the release of rCloud, a cutting-edge testing platform for the blower door and duct testing industries.  The platform geolocates testing locations, performs automatic tests, creates sharable compliance reports, and secures results safely in the cloud.

RESNET participants who completed a contest form & rCloud questionnaire were eligible to win this year’s contest.  Out of approximately 50 contestants, Craig Senglin of Energy IQ came home with the prize.

Even though blower door and duct testing has been around since the ‘80s, there’s still the occasional question about the necessity of air leakage testing versus just going through with visual inspections. This is sometimes followed with arguments about equipment expense, training time, or that homeowner money could be better spent elsewhere – the “bang for your buck” model.

Let’s explore the reasons why how blower door and duct leakage testing actually saves auditors’ and homeowners’ time and money.

1. Results give customers faith

   If you are selling a job, it makes sense to test the ducts to give the homeowner an appreciation of the performance they are likely to get out of you versus your competitor.

   If you are testing to Code, don’t
