Pre-War 4-7 Stories
This playbook summarizes 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.
Pre-War Low-Rises, typically between 4 and 7 floors in height, are found in virtually every context, from lot-line to free standing buildings. Buildings in this typology rarely include mixed uses and/or tenant amenities.
The pre-war building selected for study is a 7-story, market-rate residential building in Upper Manhattan, New York. The building has masonry exterior walls enclosing 56 apartments across 41,800 gross square feet.
