New York City Housing Authority’s (NYCHA) Permanent Affordability Commitment Together (PACT) projects are an innovative partnerships between public, private, and non-profit entities formed address issues of affordability at over 70,000 NYCHA units throughout New York City (NYC). The PACT program takes a holistic approach in evaluating comprehensive capital needs upgrades, paired with deep energy renovations, that enhance property management, and expand on-site amenities and social services. These projects are tackling some of the most difficult and pressing questions NYC faces as it looks to decarbonize buildings and while improving the lives of tenants. The issues are complex and varied, with questions like, “How do you maintain and expand affordable housing while developing cost effective capital needs upgrades and electrification scoped to existing buildings? How do we embed and tackle strategies that enhance occupants health and well being, while also planning for the future weather and climate risks?”. This session will explore the decision-making process throughout the design development and scoping of one of the PACT clusters consisting of 7 buildings, 423 dwelling units in the Bronx. Speakers from the developer, energy and sustainability consultant, and architectural firm involved in developing the scope will share their experience in the efforts to understand the energy and operational cost impacts, first costs, long term performance, and occupant health and satisfaction of potential project scopes and how this informed the final approved project scope.
