This report focusing on the “prewar, 3-7 story” building stock was authored by NYSERDA & Steven Winter  Associates for Building Energy Exchange and published in March 2021. The report emphasizes retrofit strategies that maximize occupant comfort and energy savings through a transition from fuel to electricity-based heating, cooling and hot water systems. Aligned with typical capital improvement cycles, the recommendations will prepare buildings for increasingly stringent efficiency and carbon emissions targets through careful phasing of work across all major building components, including upgrades to exterior walls, windows, and ventilation systems. The report describes the primary benefits of a low carbon retrofit with details on the major system upgrades needed to access those benefits.
