Join BetterBuiltNW to learn about air leakage and ventilation options to meet and exceed the 2018 WA State Residential Energy Code (WSEC-R) and 2018 WA International Mechanical Code.

We’ve all heard that we need to “Build Tight and Ventilate Right,” but do we know the proven approaches to meet code that are cost competitive, bring sales opportunities, and beneficial to resiliency, comfort, and indoor air quality?

In this no-cost 1.5-hour online training we briefly cover why it’s important to provide whole house ventilation in homes permitted under the WA Code and then dig into the most common strategies for getting each component right. This includes strategies for achieving tighter buildings and then a review of the most common ventilation strategies with some tips and tricks along the way to make it work effectively.

The training also provides insights on the business benefits of meeting/exceeding the energy code, as well as analyzes the value propositions for using a home energy rater or consultant to help you qualify for tax credits and incentives.

Join Dan Wildenhaus, Technical Advisor and Industry Liaison for BetterBuiltNW, on this journey to getting homes dialed in for the energy code, certification programs, and most importantly our homebuyers’ future experience.


A condensed video version of this training is available (offered without continuing education credits).
