Wisconsin has one city with a local benchmarking ordinance that affects commercial buildings.
On March 7, 2023, the Madison Common Council unanimously approved the Building Energy Savings Code, which includes requirements for energy benchmarking and building tune-ups.
Title: Building Energy Savings Code
Date Passed: March 7, 2023
The Building Energy Savings Code, also often referred to as the Building Energy Savings Program (BESP), was adopted on March 7, 2023 to help large commercial building owners identify ways to increase energy efficiency, save money and reduce emissions. BESP requires non‐residential commercial buildings 25,000 sq. ft. and larger to benchmark their energy use once a year and provide a summary report to the City. BESP also requires non‐residential commercial buildings 50,000 sq. ft. and larger to tune up and report results every four years. For mixed-use buildings, only the non-residential portion counts toward the size threshold for the program.
Requirements for BESP will phase in over three years, from 2024 to 2026. For benchmarking, the largest buildings would begin in June 2024, medium in June 2025, and smallest in June 2026. Building tune‐ups also be phased in, with the largest buildings going first. The largest buildings are required to complete their first tune‐up by October 2025. The code will go into effect on January 1, 2024.
City staff will provide training and support services such as free training events and a Help Desk to ensure building owners and managers understand how to successfully benchmark and tune‐up their buildings. They will also provide customized reports for building owners to better understand their building's performance and learn about potential energy efficiency improvements.
Madison previously had a voluntary public/private energy benchmarking program, which began in September 2015.
