This project supports East Lansing's Climate Sustainability Plan by investigating heat pump implementation in federally- and municipally-owned buildings. It aims to provide valuable technical information for decision-makers in East Lansing, facilitating HVAC facility upgrades to heat pumps and reducing energy consumption. The project delivers a comprehensive report with two parts: (a) "Path to Decarbonization: Initiating the Conversation" encompassing stakeholder interviews and case studies, and (b) "Road to Electrification: Heat Pump Upgradation" offering a factsheet on retrofitting heat pumps and retrofit design strategies, demonstrated by the successful retrofitting of the Hannah Community Center. Concluding with policy and design recommendations, the project aims to promote decarbonization through heat pump retrofits in various communities, with adaptable report materials for wider implementation.
