Did you know your home has an efficiency rating similar to a vehicle’s MPG (miles per gallon) rating? RESNET, the Residential Energy Service Network, created the Home Energy Rating System Index, often referred to as HERS. The HERS Index is the standard measuring stick for home energy efficiency. To learn more about HERS raters, visit our Certification page.
Intro to Energy Audits
An energy audit is a 3 to 4-hour in-depth assessment of your building envelope conducted by a certified RESNET Home Energy Rating System (HERS) Rater. According to RESNET, home energy audits have three main objectives:
- Figuring out where and how energy is being lost
- Locating inefficient operating systems
- Determining cost-effective ways to enhance home efficiency and comfort
A general energy audit collects detailed information about your energy usage and associated costs. Midwest Energy Rating and Auditing employs an infrared camera, blower door testing, duct leakage testing and other diagnostics to assess:
- The amount and location of air infiltration
- The amount of HVAC duct leakage
- The efficiency of wall and ceiling insulation
- The existence or possibility of combustion issues
Energy auditing isn’t just about finding problems; it’s also about designing solutions. As our certified RESNET HERS rater evaluates your entire building envelope, a computer analysis will identify problem areas and create a report outlining recommended improvements. Midwest Energy Rating and Auditing can then suggest a qualified contractor to perform the specified work.
