Energy efficiency upgrades in multifamily buildings could save building owners and residents up to $3.4 billion nationwide, according to a report released by CNT Energy and the American Council for an Energy-Efficient Economy (ACEEE).

Engaging as Partners in Energy Efficiency: Multifamily Housing and Utilities demonstrates that energy use in multifamily buildings can be reduced substantially, and cost-effective upgrades can result in utility cost savings of 15 to 30 percent in buildings with five or more residential units. The key to unlocking the savings, the report finds, is for energy utilities and apartment building owners to work together more closely to develop effective energy efficiency policies.

“We have billions essentially sitting untapped in our apartment buildings. We can harness that by simply setting better policies for efficiency for apartment buildings,” said Anne McKibbin, CNT Energy policy director and coauthor of the report. “Partnering with utilities is a crucial part of the process. Building owners and other housing industry players need to work with their utilities, engaging them directly and in local and state regulatory proceedings,” she said.

The study examines utilities’ involvement in energy efficiency efforts across the country and identifies strategies that the multifamily building community can use to work together for improved efficiency.

The report identifies regions where the multifamily sector could see particularly dramatic benefits from improvements in energy efficiency policy. These include Florida, Illinois, Texas, and the District of Columbia—regions that have a substantial number of multifamily buildings and energy policies that leave significant room for improvement.

“Utilities and local regulations vary dramatically from state to state and region to region, so there is no one-size-fits-all solution,” says Eric Mackres, ACEEE senior policy analyst. “The common thread is that partnering with the utility is crucial. This report outlines a variety of strategies that can help the multifamily housing sector to engage electric and natural gas utilities in order to expand the resources available for energy efficiency retrofits.”
