Completing deep energy retrofits of existing multifamily buildings is paramount to sufficiently reducing greenhouse emissions in the built environment. RetrofitNY is a NYSERDA pilot program challenging six highly qualified design/construction teams to create solutions to retrofit six existing multifamily buildings ranging from two to seven stories, in NYC and upstate NY, to get as close as possible to net zero, without relocating the residents. The designed solutions will be tested at the six selected buildings and extensive M&V will be conducted. Certain solutions may be applicable to new construction. In October, these teams will have early stage designs with projected costs and energy savings. Join the manager of RetrofitNY along with design-team members to learn about the solutions they are considering and the challenges they are facing for their respective projects.
