How does the program work?
- Upon Income qualification of the property, an energy assessment of the property is conducted to identify opportunities to enhance its energy performance
- A Scope of Work is created for approval from the owner and THDA
- Upon approval, the property is upgraded
- Final inspections are completed before issuing a certification of completion
What is an energy assessment?
A multifamily property energy assessment is the first step to determining how much energy the property consumes and evaluating the measures that can be taken to make the property more energy efficient. An energy assessment will identify where the property is losing energy and may save significant amounts of money over time when corrected.
Assessors will use equipment such as blower doors, which measure the extent of leaks in the building envelope and reveal hard-to-detect areas of air infiltration. Additionally, they will visually inspect the heating and air conditioning ductwork for air leaks, determine the heating systems’ efficiency, check the water heater and its temperature setting, and inspect lighting, appliances, insulation, and more.
Is there a charge for weatherization services?
There is no charge to obtain an energy assessment. The program can provide many green upgrades to multifamily property owners at little to no cost.
Who funds the program?
The U.S. Department of Energy, through the Bipartisan Infrastructure Law (“BIL”) has funded THDA’s Multifamily Weatherization Assistance Program (“WAP-BIL”).
Who is the multifamily service provider?
