What is Illinois Home Performance?

Learn about home energy upgrades in Illinois, who is eligible to participate, and what to expect during your project.

Illinois Home Performance with ENERGY STAR® (IHP), aims to help Illinois home and property owners decrease their energy costs and increase the comfort, safety, durability, and value of their homes. Homeowners achieve these benefits by working with qualified contractors to take a "whole-home" approach to energy upgrades. Since 2010, thousands of Illinois homeowners have reduced their energy use by 15% or more by completing home energy upgrades through IHP.

What is a Home Energy Upgrade?

Is your home drafty, cold in the winter, hot in the summer, or excessively dusty? Are your energy bills too costly? These are all common symptoms of a home that may be in need of an energy upgrade. Fortunately, there are a number of cost-effective solutions to these problems. IHP promotes a "whole-home" approach to energy upgrades, which takes the entire home and all of its systems into account when diagnosing performance issues and prescribing remedies. IHP helps homeowners make these improvements in order to improve their comfort and save them money on utility bills. After the improvements are complete, the program acknowledges each qualifying home with a Certificate of Completion to document and communicate the value of the investment that has been made.

Who is eligible?

  • Single-family home, townhome, or individual condo in a building of 4 or less units with heating and/or cooling equipment specific to the individual unit*
  • A building of 4 or less units with shared heating and/or cooling equipment may also be eligible if the upgrade addresses the building as a whole*
  • The building's original construction must be completed prior to audit (that is, IHP is only applicable to existing homes, not new construction)
  • Home must be located within ComEd, Nicor Gas, Peoples Gas and North Shore Gas utilities. 

*Contact (866) 395-1032, ext. 1, with any questions.

The IHP process

IHP can only be offered by IHP Participating Contractors. Each IHP project must follow the following three-step process:


First, a qualified energy professional will interview you and visually inspect your home. Next, he or she will use specialized equipment, including a blower door, to identify hard-to-detect issues such as missing insulation and areas where air leaks into and out of your home. You'll receive a set of recommendations unique to your home, explaining how to fix your comfort and safety issues and stop wasting energy.


Once you decide to undertake the improvements outlined in the work order, your Participating Contractor will make sure the work gets done according to the highest industry standards. Learn more about basic building science and the most common improvements.

Verification and Quality Assurance

Before leaving your home, the contractor will repeat diagnostic tests from the assessment to ensure the work was completed correctly and yields positive results. Also, Illinois Home Performance partners conduct third-party quality assurance inspections to maintain consistently successful results.

Participating in Illinois Home Performance means you are able to earn an IHP Certificate of Completion documenting your investment and highlighting the home improvements made and energy savings achieved. When it's time to sell your home, this documentation will be helpful in explaining the improvements you've completed. Learn more here.
