Case Studies of Energy Efficiency Retrofits to Multifamily Affordable Housing in Minnesota

Affordable housing is critical for low-income Minnesota residents, but many affordable multifamily housing units are in need of repair and come with high-energy bills. Increasing the energy efficiency of multifamily rental housing saves energy, improves residents’ health and comfort, and helps to maintain reasonable living costs. Improving the efficiency of these buildings also helps Minnesota meet its Conservation Improvement Program energy savings goals and contributes to the preservation of the state’s affordable housing stock (NRDC/NHT).

These cases studies illustrate the impact of energy efficiency retrofits in Minnesota’s multifamily housing stock. Each offers an overview of a project including information on cost, energy savings, rebates and financing. They include projects across a range of scales from boiler controls in townhomes to significant upgrades involving mechanical and envelope improvements.
