What is the Biggest Loser?

Ann Arbor's Biggest Loser is a home energy competition run in partnership with the GreenHome Institute, a local non-profit. From March 1st through December 31st 2022, participants will aim to save energy by reducing their gas and electric bills - and the household with the largest reduction in their energy bills will win $500! Other prizes will also be available, based on improvements in Home Energy Score, decreases in water usage, and more! For more details, check out the list of prizes and see the competition eligibility criteria.

Sign Up & Win!

Early registrants for the Biggest Loser may be eligible for a free home energy score audit! This audit will include ​​an assessment of the home's current performance and identify areas of improvement, typically including insulation, air sealing, lighting, etc​. The report generated by this audit could help you in developing a plan to reduce your energy usage and win the competition! For more information, see the audit eligibility criteria below.

  • Participants must sign a utility release disclosure. 
  • Participants must have lived in their home for a full year before the start of the competition. 
  • Participants must live in their home full time and cannot reduce energy by leaving their home for long periods. 
  • Participants should not sacrifice their health, safety, or comfort; please do not subject yourself to extremes in temperature in order to win. 
  • Participants who are using solar power to reduce their energy may only count the solar that is used directly by their home, and not the solar that is sent back to the grid. 
  • Participants may own or rent their home.

​Free Home Energy Score Audit Eligibility 

  • Participants must​ register for The Biggest Loser competition and submit their utility release.
  • Participants' home energy use and square footage will be analyzed to determine the need for an audit. The GreenHome Institute reserves the right to decline a free audit, based on these criteria.​
  • Participants who are renting must have their landlord agree to the audit.
  • Participants must be available during a timeframe offered by the auditor.
  • To learn more about what the audit entails, please visit https://greenhomeinstitute.org/homeenergyscore/
  • Participants who do not win a free energy audit may purchase one here; or, for income-qualified participants, check to see if you qualify for a free audit through the Washtenaw County Community Action Agency​.

Indoor Air Qual​ity​

You can learn more about the indoor air quality portion of the competition during an energy audit or at our informational webinar. In the meantime, you can visit the GreenHome Institute's website to begin exploring air quality sensors that can be used to measure your home's air quality in real time. Be sure to place these devices in high-use areas of your home, such as living rooms or bedrooms.  Air quality metrics that must be measured for the competition include:

  • CO2
  • VOCs
  • PM2.5
  • Humidity 
  • Temperature
  • Radon (you may use a county radon test at the start and end of the competition, rather than using an ongoing monitoring device.​​​)​
