HVAC Issues in 2021 WA & Seattle Commercial Energy Codes

The March 20th webinar will cover HVAC provisions of the 2021 Seattle and Washington state energy codes for commercial and multifamily buildings, highlighting requirements that are new to this edition and the differences between the Seattle and State codes.

Discussion topics will include the Total System Performance Ratio (TSPR), data center standards, restrictions on fossil fuel and electric resistance heating, balanced ventilation, DOAS, energy recovery, and system alterations, as well as impacts of the new “fossil fuel compliance path” and Initiative 2066.

Duane Jonlin, FAIA, will present the code requirements, and special guest Ben Roush, PE, of FSI Engineers will demonstrate design options. Q&A time will follow.

Learning Objectives:

1. Reduce energy use and carbon emissions through optimal HVAC design
2. Identify significant new HVAC-related code provisions
3. Make code-compliant system selections
4. Identify where heat pump systems are required
5. Understand design implications of recent legal and legislative actions
