HERS Certificate for Efficiency

We’ve always built energy-efficient custom homes in Ohio. And now we’ve got the HERS ranking to prove it!

Bob Webb receives HERS Index Score of 50 for energy efficiency

The lower the number, the more energy-efficient the home. That’s why the RESNET (Residential Energy Services Network) recently awarded Bob Webb Custom Homes an enviable average HERS index score of 50, a number below scores awarded to other custom home builders throughout Ohio.

Why is the score of 50 so significant? Because the U.S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index while a standard new-build home typically scores a rating of 100. So a score of 50 is outstanding, and 50 points lower than other home builders throughout the state.

What does that mean for you as a home buyer? It means that Bob Webb should be your builder. Most importantly, it means when you build with Bob Webb, your home will be 80% more efficient than the average resale home and 50% more energy-efficient than a typical new-build home from any other builder.

What is the HERS Rating?

The Home Energy Rating System (HERS) Index was developed by RESNET and is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance.

How is the HERS Rating determined?

A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score.

To calculate a home’s HERS Index Score, a certified RESNET HERS Rater does an energy rating on the home and compares the data against a ‘reference home’– a designed-model home of the same size and shape as the actual home, so the score is always relative to the size, shape and type of home assessed. (In this case, comparable new-build homes by custom builders throughout Ohio.)

Some of the variables included in an energy rating are:

bwg-bullet All exterior walls (both above and below grade)
bwg-bullet Floors over unconditioned spaces (like garages or cellars)
bwg-bullet Ceilings and roofs
bwg-bullet Attics, foundations and crawlspaces
bwg-bullet Windows and doors, vents and ductwork
bwg-bullet HVAC systems, water heating system, and your thermostat

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.
