Elevate Energy constructed a database of 143,000 Chicago multifamily buildings and segmented them based on age, size, and other traits in order to better understand the Chicago multifamily sector. The segmentation findings point to opportunities to improve ChicagoÕs energy efficiency programs. The size of the unsubsidized lower-cost multifamily market in Chicago, added benefits of improved health outcomes for low-income residents, and greater investment in disadvantaged neighborhoods strengthen the case for prioritizing multifamily market for energy efficiency. The report is organized into three parts. The first part describes the datasets used to build a database of ChicagoÕs multifamily buildings. The second reviews key findings from the analysis. The third section provides recommended improvements to efficiency programs based on the segmentation.

This report explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

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.
