Join BetterBuiltNW to learn about balanced ventilation and ERV/HRV options to meet and exceed the 2018 WA State Residential Energy Code (WSEC-R).

The attention on indoor air quality is higher than ever before with homeowners confronting wildfire smoke, viruses, and a greater awareness of healthy indoor environments. Among home builders and designers seeking airtight performance with balanced ventilation, many have decided to go with either a heat recovery ventilator (HRV) or energy recovery ventilator (ERV).

In this no-cost 1.5-hour online training we cover several balanced ventilation systems and approaches to consider, and help builders and trades decide which provides the best solution for their projects and customers. 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, as he goes over the different use cases for HRVs/ERVs and help you navigate the strategies and pitfalls to help ensure an effective installation.


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