This report was developed to help inform national stakeholders about the strategies that have been used to achieve deep energy savings in the multifamily housing sector through energy efficiency upgrades. These strategies could be used as models in areas where utility program administrators and policymakers seek to achieve deep energy savings in the multifamily building stock for the purposes of reducing energy costs, creating comfortable and healthy homes, meeting regulatory requirements, or reducing the environmental impacts of energy consumption. This report includes a national multifamily market characterization, barriers and opportunities for program and policy efforts, and eight exemplary case studies from across the country.

In 2011 the City of Boulder, Colorado enacted its “SmartRegs” ordinances that require all single family and multifamily rental properties to meet a minimum energy efficiency standard by January 2019. The SmartRegs initiative is designed to help the city achieve its ambitious carbon emissions reduction goals and to improve the quality, safety, and marketability of Boulder’s rental housing stock.

This fact sheet provides promising approaches for Better Buildings programs seeking to accelerate workforce development to support building energy upgrades. These approaches are organized by estimated level of effort and include rough estimates of cost ranges for implementation.
