What happens when you put four sustainable building experts involved in energy code development in a room and ask them to bring their favorite—and sometimes, most controversial—topics for discussion? You end up with more questions than answers!
In this roundtable episode hosted by Robb Aldrich, our guests ask each other these tough questions related to our nation’s energy codes:
- Performance Metrics: How can energy codes be simplified? Is energy use intensity (EUI) a viable alternate metric?
- Gas Bans: If jurisdictions cannot ban gas, how can we put electrification in the energy code?
- Embodied Carbon: How should embodied carbon accounting be incorporated into energy codes?
- Robb’s Bonus Question #1: How are building inspectors dealing with complicated energy codes?
- Robb’s Bonus Question #2: Should there be electric vehicle (EV) charging requirements in energy codes?

Have you checked out the new on-demand training program, Air-Source Heat Pumps: Achieving Comfort and Efficiency in Cold Climates?
Our episode host, Robb Aldrich, has been researching, consulting, and providing training on heat pump technology for over 20 years. During that time, heat pumps have evolved to meet the demands of residential heating in cold climates—resulting in significant implications for decarbonization and electrification goals.
Robb is sharing practical applications, important considerations, and real-world examples of the good and the bad (and the sometimes ugly) in Air-Source Heat Pumps: Achieving Comfort and Efficiency in Cold Climates available exclusively through SWA Academy.
This user-paced training program features eight chapters with short video lessons that deep-dive into elements of inverter-driven air-source heat pump implementation, from pre-design to installation to operations and maintenance.
