This report focusing on a segment of buildings (4-7 stories) constructed in the post war period is part of a series authored by NYSERDA & Steven Winter Associates for Building Energy Exchange and published in March 2021. The post-war building selected by the authors for study is a 7-story, market-rate residential building in Brooklyn, New York. The building has masonry exterior walls enclosing 83 apartments across 76,113 gross square feet. Typical of a large swath of buildings in New York City (as well as many other regions), the building is thought to be representative of the most common challenges that will be encountered by anyone looking to perform a deep retrofit of an occupied multifamily building.
