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 guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.
