What is the Resident Race to Zero Energy Challenge?

The Race to Zero Energy Challenge is a home efficiency competition run in partnership with the GreenHome Institute, a local non-profit. Beginning July 1st through December 31st 2022, participants will aim to increase their home's efficiency by reducing their gas, electric, and water usage - and the households with the largest reductions will win prizes of up to $500! For more details, check out the list of prizes and see the competition eligi​bility criteria.

Sign Up & Win!

Early registrants for the Energy Challenge 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 win the competition by reducing your energy and water usage! For more information, see the audit eligibility criteria below.

In addition, Ecotelligent Homes is offering 5% off attic insulation for the first five participants who claim the offer. See more information on Ecotelligent Homes here.

​Free Home Energy Score Audit Eligibility 

  • Participants must​ register for the Resident Race to Zero Energy Challenge 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 must be available during a timeframe offered by the auditor.
  • To learn more about what the audit entails, please visit
  • 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 indo​or air quality portion of the competition during an en​ergy audit. 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.​​​)​
