Building Tune-ups

Just like a car or bicycle, buildings need to be tuned-up regularly to make sure they are operating at their best. Building tune-ups check and adjust building energy systems, like lighting and HVAC controls, to make sure existing systems are running well without wasting energy or money. Tune-ups reduce building energy use by 10-15% on average while saving money, improving comfort for building occupants, and extending the life of equipment. 

Commercial buildings 50,000 sq. ft. and larger are required to tune-up every four years. Buildings that are already very energy efficient or buildings that have recently taken actions that substantially improve energy efficiency may be eligible for an alternative compliance pathway. These requirements are being phased in beginning in 2025.

Coming in 2025

  • Commercial buildings 100,000 square feet (sq. ft.) and larger are required tune-up for the first time by October 31, 2025. 
  • The tune-up reporting template, guidance, and supporting materials will be available on this page in January 2025.  

Program Information

What are my compliance options?

Buildings owners can choose between four compliance pathways: 

  1. Complete a building tune-up. 
  2. Choose an Alternative Compliance Pathway that demonstrates you have a high efficiency building or have recently taken actions that substantially improved your building’s efficiency.
  3. Apply for a 1-year extension if you meet one of the qualifying criteria:
    1. Recent change in building ownership.
    2. +50% of the building is vacant and not leased for at least 6 months of the previous year.
    3. Building is undergoing a major renovation.
    4. A building’s owner is experiencing financial hardship such as bankruptcy or foreclosure.
  4. Apply for an exemption if the building is being demolished.

What is a building tune-up?

A building tune-up is a process of reviewing of energy systems, controls, and maintenance practices, and making minor adjustments and fixes as needed to bring them up to a good state of performance. Meta-analysis by Pacific Northwest National Laboratory (PNNL) shows that tune-ups result in a median annual energy savings of 12% and a median annual cost savings of $0.16 per square foot for a building. 

What building systems are included in a tune-up?

Base building systems or subsystems that use energy or impact energy consumption are checked during a tune-up, including: 

  • building envelope 
  • HVAC systems (heating, ventilation, and air conditioning) 
  • domestic hot water systems, including water softening equipment 
  • and electrical lighting systems. 

For each system, the following elements (if present) are checked to make sure they are meeting the specifications defined by the building owner: 

  • Sensors
  • Schedules
  • Set points
  • Outside air control/ventilation
  • Equipment controls
  • Maintenance or repair needs
  • Design recommendations

Operational adjustments or repairs are included in a tune-up when an element does not meet the building owner’s requirements or is in need of maintenance or repair.  

Who can perform a tune-up?

Tune-up must be carried out by a qualified tune-up specialist or a team under their supervision. It is the Tune-up Specialist's job to make sure that building systems are operating per the needs and expectations of the building owner and are not in need of maintenance or repair. A Tune-up Specialist can be on-site staff or a contracted service provider, as long as they have the proper qualifications.

What qualifications are needed to be a Tune-Up Specialist?

A Tune-up Specialist must have at least three years of experience in building commissioning, tune-ups, energy auditing, or building energy system management and hold one of the following certifications:

Is there a list of Tune-Up Specialists?

The City of Madison does not maintain a list of qualified Tune-up Specialists. A Tune-up Specialist can be on-site staff or a contracted service provider, as long as they have the proper qualifications. 

To find qualified contractors, check out Focus on Energy's list of Trade Allies. Look for Trade Allies that perform the following services:

  • Retrocommissioning
  • Commissioning
  • Energy Planning
  • Energy Management
  • ASHRAE Level 1 Audit

What are the Alternative Compliance Pathways?

We recognize that many building owners are making great strides toward achieving energy efficiency. Rather than conducting a Tune-Up and to allow flexibility for owners, buildings that are already highly energy efficient, or those that have recently undergone improvements that substantially improve energy efficiency can apply for an Alternative Compliance Pathway by submitting proof of one of the follow conditions or certifications: 

  • Certified ENERGY STAR score of +75 for 2024
  • LEED Gold or Platinum (O+M) within last 3 years
  • Complete full commissioning or retro-commissioning within last 3 years
  • Net Zero Energy Certification within last 3 years
  • +10% improvement in energy efficiency over last 4 years
  • Completing ASHRAE Level II audit and implemented recommendations with a simple payback of <2 years within last 2 years
  • Demonstrate building has energy use intensity (EUI) of 20 kBTU/sq. ft. for at least 2 of the last 3 years
  • Received any of the following awards within the last 3 years:
    • Dane County Climate Champion recognition in the category of Building Energy Use
    • Better Buildings Goal Achievers recognition from the U.S. Department of Energy’s Better Buildings Challenge
    • BOMA 360 designation and received +6 points for Energy Star Benchmarking, Building Energy Management, and Energy Audit and System Commissioning
    • BOMA TOBY award in the Office or Earth categories with +5 or +6 points, respectively, for Benchmarking & Performance Rating
