NYC Retrofit Accelerator

Cities adopting and implementing building performance benchmarking policies that require building owners to track and report their buildings’ energy and/or water use on a regular basis are collecting a trove of data that can be used to accelerate investments in energy upgrades in buildings. For energy efficiency program implementers, this data can also be used to drive increased participating in city- and utility-sponsored efficiency programs.

This case study of the NYC Retrofit Accelerator looks at how city and utility energy efficiency program implementers can use this data to proactively identify energy efficiency upgrade opportunities and accelerate investments by building owners in their jurisdiction. It also explores a successful example of partnership between local government and utilities.

This case study is part of IMT’s Putting Data to Work toolkit. This comprehensive toolkit is the result of a three-year pilot project that aimed to use building performance data and asset information to help city government sustainability leaders, utilities, and efficiency program administrators and implementers make more informed business decisions and increase building efficiency. The project examined energy efficiency program design and delivery in the District of Columbia and New York City to produce a toolkit of best practices, actionable tools, and case studies to enable other local governments, utilities, and efficiency program implementers to replicate successes. The full toolkit, as well as details on upcoming blogs and webinars associate with the project, is available at
