As leading home performance specialists, we collaborate with home builders to ensure accurate evaluations and ratings, helping them qualify for incentives and comply with energy efficiency standards. The Home Energy Rating System (HERS) is a vital requirement for numerous green building and energy-efficient building standards, making it the foremost guideline in the United States.

Understanding HERS Ratings:

HERS Ratings allocate a score to the evaluated home on a scale of 0-150. Lower numbers indicate less energy consumption (a HERS score of 0 signifies a "zero energy home" that generates as much energy as it consumes), while higher numbers imply greater energy consumption. A typical new home would have a score of around 100, with most existing homes ranging between 100 and 150.


Advantages of HERS Ratings:

Obtaining a HERS Rating for your home offers builders and realtors an opportunity to differentiate their properties in a competitive real estate market. A good HERS score provides an objective, quantifiable representation of a home's energy efficiency.

When purchasing or constructing a home, an energy rating enables you to compare properties based on energy efficiency.

Energy ratings are compulsory for securing an energy-efficient mortgage (EEM).
Energy ratings are obligatory for a home to receive the ENERGY STAR label.
Energy ratings can help qualify your home for specific utility rebates.

     It was recommended that I upgrade my HVAC to GEO by a heating company. I had Rob come in and check my house, he is very professional and knolagable. He ran a complete series of tests, showed me with thermo pictures and real numbers how I could insulate better, upgrade my HVAC without going to the expense of GEO and save more money. Well worth it.

    An energy audit can be a pleasant and informative experience. It  was such during the one completed by Rob Novak for my house recently. In addition to many helpful suggestions to seal warm air leaks in all areas of the house, he found a problem with carbon monoxide in one place. The water heater chimney was blocked. There was a squirrel which had died inside the chimney,...

    The main thing we took away from the energy assessment was the confidence that comes with having guidelines for laying out a course of action. We knew we had issues with the home's envelope but weren't certain where to start. Using a combination of basic and complex technologies, Rob was patient and professional. He identified problem areas and possible solutions and presented...

    We were extremely impressed with the energy audit that Home Star Iowa did on our home a few months ago. The knowledge he had in regards to the energy saving tips he provided was top notch.

If you are wanting an energy audit done on your home - there is no...

     As the owner of a 100 year old home, I sometimes wonder where I should start in making my home more comfortable.  Rob came in and went through all of my utility bills, measured every window, checked the efficiency of my boiler and hot water heater, did a blower door test and walked through the house with an infrared camera and showed me where I need insulation, where the air infiltration is coming from.  A day later, he gave me a very comprehensive report that showed me the steps I can take...
