Ultra-Efficient Housing: The Minneapolis Public Housing Authority Strategy (Stephan Tanner & Tim Delhey Eian)
Housing accounts for a large amount of energy use and Carbon pollution. Public housing in particular has not seen many retrofits and refurbishments. Therefore, public housing offers the potential for significant performance improvements with the help of the Passive House paradigm, which offers the potential to elevate public housing tenants to take a leadership role in greenhouse gas reduction, and completely redefine the paradigm. Together with the Minneapolis Public Housing Authority, Intep embarked on a journey to establish the ultra-efficient housing strategy for an entire portfolio consisting of single family homes, duplexes, townhomes, low and high-rise buildings—over 5,000 units in total.
