Scalable Multifamily Retrofits: Case Studies from Energiesprong & Two US Practitioners

Energiesprong and practitioners selected by RetrofitNY are developing standardized and scalable methods to achieve whole-building near-zero energy retrofits while maintaining multifamily tenants in place. Energiesprong, based in Europe, has successfully transformed 4,500 affordable units and RetrofitNY is currently in proof-of-concept phase.  The session will provide an introduction to standardized retrofits for multifamily housing, an overview of the best practices in Europe, and the practical implementation in the US market. Two case studies by US practitioners participating in NYSERDA’s RetrofitNY program will focus on the design process, off-site panelization, the use of laser scanning, construction cost, and funding requirements. The first is a wood-framed 24 unit building employing a panelized approach and the second is a four-story masonry building that will receive a high-R EIFS exterior and high-performance HVAC.
