Steps to a HERS Rating:
- Home Audit/Site Inspection
- Energy Modeling Using REM/Rate Software
- Economic Analysis and Simulations of Energy Efficient Improvements
- Air Leakage Testing on the Home Envelope and the Duct System
- Issuance of the HERS Certificate, and ENERGY STAR Certificate or other building certification, if the home qualifies
A home energy rating involves an analysis of a home's construction plans and onsite inspections. Based on the home's plans, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home's design. This analysis yields a projected, pre-construction HERS Index.
Unlike a Building Performance Audit or a weatherization assessment, a home energy rating is a recognized tool in the mortgage industry. Home energy ratings can be used in a variety of ways in the housing industry. Since a rating quantifies the energy
performance of a home, the HERS Index provides an easily understandable means to compare the relative energy efficiency of different homes.

Comprehensive Home Energy Audits
Performing a comprehensive energy audit on your home can give you the information you need to make targeted improvements to your home without wasting money and time. Home energy audits can be performed on houses, townhomes, condos, or whole multifamily buildings.
IAER members are experienced in analysis of existing homes, especially if they are BPI certified. Many of the same tests apply to Audits as in Ratings, but there is more focus on combustion safety, indoor air quality, and moisture issues since the home may have been built years ago and renovated since then.
