Kirbor Energy Efficient Homes:
The Key Is In The Rating!

In today’s home building environment, actions speak louder than words. A lot of builders claim their homes are built energy efficiently, or that they build with energy efficient practices and procedures. When in fact, that’s just a lot of hot air.

Kirbor Homes introduces our KEE program. Kirbor’s Energy Efficiency program. It’s a program rooted in the Home Energy Rating System (HERS) and utilizes the nationally-recognized and industry-standard index to measure the energy efficiency of every home we build. With KEE, you’ll discover the key to proven energy efficiency is in the rating!

What is the HERS Index?

The HERS Index is a measurement of the energy efficiency of a home built by Kirbor Homes, and is the basis for our KEE program. There are many reasons why a home you buy should use this measurement. A HERS score can tell you so much about a home you buy from Kirbor Homes. The HERS score will tell you how well the home performs energy-wise.

The HERS report will outline the energy features of the home and the expected cost of utility bills. The lower the score, the better the rating.

What Does The HERS Energy Rating Mean?

Think of the HERS index rating number as your home’s MPG (miles-per-gallon) sticker. Just like the MPG tells you how wisely the car you purchased uses fuel, so too does the HERS index rating number tell you how smart your new home built by Kirbor Homes is when it comes to energy efficiency. An energy rating will rank your home based on its performance and assign it a HERS Index Score. Kirbor Homes’ KEE program is designed so that each and every home built comes in with a lower rating number.

A lower HERS Index Score signifies a more energy efficient home. Just remember when it comes to the number, the lower the better. Homes with lower HERS Index scores cost less to run, provide better home comfort and enjoy higher resale values.

How does the HERS Index work?

A certified RESNET Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score (the HERS Index 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 home built to the 2004 International Energy Conservation Code is awarded a rating of 100.

  • A home with a HERS Index Score of 70 is 30% more energy efficient than the RESNET Reference Home.
  • A home with a HERS Index Score of 130 is 30% less energy efficient than the RESNET Reference 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.

To achieve the rating, Kirbor Homes’ KEE program has a certified HERS Rater do a comprehensive HERS home energy rating on your home to assess its energy performance. The energy rating will consist of a series of diagnostic tests using specialized equipment, such as a blower door test, duct leakage tester, combustion analyzer and infrared cameras. These tests will determine:

  • The amount and location of air leaks in the building envelope
  • The amount of leakage from HVAC distribution ducts
  • The effectiveness of insulation inside walls and ceilings

Other variables that are taken into account include:

  • Floors over unconditioned spaces (like garages or cellars)
  • Attics, foundations and crawlspaces
  • Windows and doors, vents and ductwork
  • Water heating system and thermostats

Once the tests have been completed, a computerized simulation analysis utilizing Residential Energy Services Network (RESNET) Accredited Rating Software will be used to calculate a rating score on the HERS Index. A certificate with your home’s rating will be given to you at closing.

The national training and certification standards for HERS Raters were created by RESNET, and are recognized by federal government agencies such as the Environmental Protection Agency (EPA), the U.S. Department of Energy (DOE), over 150 building code jurisdictions and the U.S. mortgage industry.
