Energy Efficiency

At Concept Builders we strive to make our homes Very Energy Efficient by using 95% or more LED Lighting, High-Efficiency HVAC systems, Blown-in Wall insulation systems and more.

All of our homes are HERS Rated homes, Certified through RESNET who use local independent inspectors that come at various stages of construction to make sure we comply with the program requirements by inspecting insulation, duct work, window r-values and installation and they even do a vacuum test on the whole house and duct system to measure air leakage. We take additional steps to go beyond the requirements of the program and often end up with scores in the 50's, and only have to achieve a score below 85 to comply with the program.

What is RESNET?

The Residential Energy Services Network (RESNET) is the independent, national non-profit organization that homeowners trust to improve home energy efficiency and realize substantial savings on their utility bills. It is the organization responsible for creating the national training and certification standards for Home Energy Rating System (HERS) Raters. To qualify as a certified RESNET Rater, home energy professionals must first complete the rigorous training and testing required, and agree to abide by the RESNET Code of Ethics and Standards of Practice. RESNET’s industry-leading standards are recognized by the U.S. Department of Energy, U.S. Environmental Protection Agency, and the U.S. mortgage industry.

What is the HERS Index?

Developed by the Residential Energy Services Network (RESNET), the Home Energy Rating System (HERS) Index is an easy-to-understand energy efficiency measuring tool that assigns a numerical value to homes based on energy performance. The lower the score, the more energy efficient the home. It’s like a miles-per-gallon label for houses.

A Lower Score Saves You More!

Outside of a mortgage loan, the highest cost of homeownership is energy. That’s why smart homebuyers ask for a home’s HERS Index Score to learn about its energy efficiency before buying. The HERS Index Score is like a MPG (miles-per-gallon) label for homes. With one number, you can compare between homes, and identify ways to improve an existing home’s energy performance. How it works is an independent and certified RESNET HERS Rater inspects and tests a home’s energy features. The information is entered into sophisticated HERS rating software, which issues a HERS Index Score. The lower the HERS Index Score, the lower the energy costs will be. And lower energy costs means you can put more money into other things, like your mortgage loan.
