Chad read email from Andy Johnson regarding HERS ratings differences between HERS 48 and 47 and appendix RC. Appendix RC requires HERS of 47 before renewals. The cost difference between HERS of 48 and 47 is significant. He explained models he ran for 47,48, 49 and the cost difference in the tens of thousands and cost between 47 and 48 is known to energy raters. He believes this is financial segregation for affordability in building a house. He recommends a HERS of 50 and cleaning up the energy code. 2. Chad explained that City Council decided the day before the BCBOA meeting that they would like the Board to provide guidance on recommendation for 2021 energy code revisions.
