ROOM- Rousseau Center

This session will provide background information on how more places in the country are switching to all-electric homes for both new construction and retrofits, and the impacts on overall energy use, greenhouse gas emissions, and indoor air quality and health. There are changes to the HVAC equipment and appliances used in all-electric homes, as well as changes to home infrastructure (such as smart electric panels and low-power appliances) that go beyond energy use to include limiting peak power requirements and grid integration capability. The session will include discussions of cost breakdowns from over 1,700 energy retrofit projects in single family homes and over 50,000 dwellings in more than 1,000 multifamily buildings, together with observations on how to optimize home electrification. This session will provide the technical background and practical advice that is needed for Raters who encounter more electrified homes so that they can understand how they work and what impact they might have on an energy rating and home performance in general.
