Green Path Home Performance Report

With today’s energy codes, a newly built home in Minnesota is more efficient than ever. Add in advancements in building science plus new energy products, and you can be sure that all the new homes you’ll find on Parade this fall will save energy dollars over virtually all older homes.

But there’s one more step you can take to be sure – select a home that has been inspected by a certified RESNET energy rater. These experts do more than look “under the hood” at a new home. They make recommendations about helping builders save energy all the time. And when they’re done, they input the data they’ve gathered into modeling software that produces a Home Energy Rating System (HERS) Index number. The HERS index makes it easy to tell which homes are most energy efficient, so you don’t need to dig into all the components (HVAC system, insulation, R values and more).

And that’s what’s at the heart of the MN Green Path program. At the Energy Tested level, Green Path provides documentation – a Home Performance Report (HPR) – that displays the home’s HERS index. In homes that have even more green features, Green Path offers two certification levels, advanced and master, reporting all green features clearly on the enhanced HPR.

The HERS Index was created by RESNET (Residential Energy Service Network) in order to give homeowners and buyers a standard by which they could measure the energy efficiency of houses they currently own or are planning to buy. You could say it is kind of like the home industry’s version of the MPG (miles per gallon) rating that you find in the auto industry and the lower a home’s HERS Index Score is, the better its home efficiency. Much like a car’s MPG sticker, a home’s HERS Index Score is increasingly being used by builders to market their properties.

BATC-Housing First Minnesota created Minnesota Green Path to help homebuyers make smart housing decisions. Like its Parade of Homes, BATC-Housing First Minnesota’s goal is to provide families with accurate information about new homes – from pricing to location to style, and now energy efficiency and green features.


How does the HERS Index work?

A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home. The U.S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index while a standard new home is awarded a rating of 100. A home with a HERS Index Score of 70 is 30% more energy efficient than a standard new home. A home with a HERS Index Score of 130 is 30% less energy efficient than a standard new home
