In the Last Analysis: An Electrified Town Garage for the 21st Century

Details matter in this analysis of a challenging building type, a 9000sf Vermont town garage. First principles were applied to assess HVAC cases: two heat-pump types, two combustion fuels, with and without photovoltaics. Baseline code metal building was compared to high performance wood. Parameters evaluated include embodied and operational emissions, peak demand, energy use, and operating cost, along with a deep dive into COPs for A2WHP and GSHP. In these days of elaborate black-box software, come see the outcome of this thorough 30-year life-cycle cost analysis.
