Home Energy Rating System
Home Energy Rating System (HERS): A home energy rating is an analysis of a home’s energy efficiency.
The Home Energy Rating System (HERS) Index 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.
What does a HERS rating say about a house?
The HERS Index MEASURES A HOME’S ENERGY EFFICIENCY and there are a lot of great reasons to have a home energy rating performed on your house.
It can tell you so much about the home you live in, like how efficiently it’s operating and where you can make modifications for greater energy savings. When you’re selling your home, a low HERS Index Score can command a higher resale price. And when you’re buying a home you can anticipate the costs of energy bills and efficiency upgrades.
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
To calculate a home’s HERS Index Score, a certified RESNET HERS Rater does an energy rating on your home and compares the data against a ‘reference home’– a designed-model home of the same size and shape as the actual home, so your score is always relative to the size, shape, and type of house you live in.
- Measurable savings of 50% or more on heating and cooling costs
- Heater and air conditioner work more efficiently so that the temperature of the home is consistent and even throughout the home.
- Homeowners will receive documentation that their Pepper Viner home meets the Energy Star and EPAct standards.
- Pride in doing your part to protect our beautiful Sonoran Desert by using less energy – 75% of all energy use is attributed to the buildings where we live and work.
