°i Tr�C 436 14th Street Oakland, CA 94612 MEMORANDUM To: Gabriel Taylor, Peter Strait (California Energy Commission) ATTACHMENT G August 13, 2019 From: Farhad Farahmand, Abhijeet Pande (TRC), Rafael Reyes (Peninsula Clean Energy) Re: Interpretation of Cost Effectiveness Analysis as it Relates to Menlo Park Reach Code Proposal As part of an amendment to the California Building Standards Code, the City of Menlo Park is seeking a requirement for all new construction buildings to be all -electric but allows for several exceptions. For residential buildings, the City is proposing to allow natural gas to be used for cooking and decorative fireplaces. For nonresidential buildings, certain categories of buildings such as public safety buildings, designated emergency centers as well as commercial buildings containing scientific laboratories that require natural gas for operational and process reasons are proposed to be exempted. This memo serves to clarify the cost-effectiveness justification of these proposals as required by California Code of Regulations (CCR), Title 24, Part 1, 410-106 and request the Energy Commission's preliminary approval of this justification. If approved, an updated version of this interpretation will be included with Menlo Park's application to the Energy Commission. The statewide investor owned utility codes and standards program developed a new construction cost effectiveness analysis for all California climate zones which included ail -electric measures as part of multiple packages. These analyses have been attached, and: ♦ Were performed for both residential and nonresidential buildings ♦ The residential prototypes included 4 end -uses in analysis: space heating, water heating, cooking, and clothes drying. These assumed savings from avoided natural gas infrastructure to and within the residence. The nonresidential prototypes included 2 end -uses in analysis: space heating and water heating. ♦ Found that it is cost-effective to construct all -electric buildings compared to the 2019 Standards ACM baseline, including all end -uses analyzed, partially due to upfront cost savings associated with foregoing a natural gas connection to the building. Menlo Park's code proposal would allow the construction of all -electric buildings which has been shown to be cost-effective using the TDV cost-effectiveness metric. We seek your preliminary confirmation that the existing cost effectiveness studies completed are sufficient to support Menlo Park's proposal, considering further that: ♦ In residential buildings, a proposed building with electric space- or water -heating is already compared to a standard building with these electric end -uses. Thus, no cost effectiveness criteria are explicitly required for the electrification of these end -uses.
