Building Energy Savings Program

The City of Madison adopted the Building Energy Savings program (BESP) in March 2023 (see Section 29.40 of the Madison General Ordinances) to improve energy efficiency in large commercial buildings community-wide through energy benchmarking and tune-ups. 

The program has two requirements:

  1. All non-residential commercial buildings 25,000 square feet (sq. ft.) or more must benchmark energy use annually.
  2. All non-residential commercial buildings 50,000 sq. ft. or more must complete a building tune-up every four years.

The program is being phased in over time according to building size as shown below. The 2024 Covered Buildings List includes buildings required to begin benchmarking in 2024. 

The 2025 Covered Buildings list will be released in January 2025.

Medium buildings:  50,000 - 99,999 sq. ft.20252026

Energy Benchmarking

Energy benchmarking is simply measuring and tracking annual energy use. Commercial buildings 25,000 sq. ft. and larger are required to benchmark their energy use annually.

Building Tune-Ups

Tune-ups detect and correct operation or maintenance issues to make sure building systems are performing at their best. Commercial buildings 50,000 sq. ft. and larger are required to tune-up every four years.

2025 Program Deadlines

  2. Requests for Tune-up Alternative Compliance Pathways, extensions and exemptions due

    Contact the Help Desk to request to follow an Alternative Compliance Pathway, receive a 1-year extension, or receive an exemption in 2025.

  3. Energy benchmarking deadline

    Buildings 50,000 sq. ft. and larger submit benchmarking data in the Building Owner Portal.

  4. Building tune-up deadline

    Buildings 100,000 sq. ft. and larger submit building tune-up report or Alternative Compliance Pathway documentation in the Building Owner Portal.

About BESP

The City of Madison is one of more than 50 U.S. cities, counties, and states that require energy benchmarking and additional actions to improve energy efficiency existing buildings. The Building Energy Savings Program advances Madison's goals of reducing carbon emissions from buildings and reaching net zero carbon emissions community-wide by 2050.

Building are currently the source of 65% of Madison's carbon emissions. Benchmarking and tune-ups save energy, cut carbon emissions, lower utility bills, provide a more comfortable space for occupants, and reduces air pollution that negatively impacts public health and the environment. Reducing annual energy use in buildings covered by this program by 10 to 15% will cut carbon emissions by an estimated 91,257 to 136,886 tons per year. That’s the equivalent of taking 17,838 to 26,757 cars off the road.
