The Economics of Electrifying Buildings: Medium-Size Commercial Retrofits

This report analyzes the technical, economic, and environmental implications of retrofitting fossil-gas-fired space heating and domestic hot water systems in a prototypical 50,000 square foot office building. The authors compared a range of system decarbonization scenarios to a conventional gas-fired system replacement including heat pump water heaters, heat pump rooftop units, energy recovery ventilation, peak heating demand management, and on-site solar photovoltaics.
