What’s New with Regs: System Efficiency – A Look into the Future



To finish out the year strong, Lindsay and Jennifer are once again joined by Dr. Rajan Rajendran! In the previous episode, Lindsay and Jennifer discussed a lot about the new Federal Minimum Energy Efficiency standards coming in the next couple years, but what about system efficiency? Rajan dives deep into this topic and what metrics such as SEER, IEER, and EER measure, as well as what they fail to measure. We also further discuss the subject of decarbonization, the AHRI Systems Steering Committee, and why using all-electric is not always the best course of action to reduce carbon footprint.
