Home Energy Audits & Building Performance Testing in Eastern Iowa
BPI Certified · DOE Home Energy Score Assessor · RESNET HERS Rater · Serving Eastern Iowa Since 2009
Home Star Iowa provides professional home energy audits, Home Energy Score assessments, and whole-home diagnostic testing for homeowners across Eastern Iowa — including Cedar Rapids, Iowa City, Marion, and surrounding communities. We also support Iowa home builders with HERS ratings, ENERGY STAR certification, and energy code compliance testing for new construction projects.
Our assessments are performed by Rob Novak, a BPI-certified Building Analyst with over 15 years of experience in home performance and building science. We are not a contractor or equipment dealer. Our only job is to give you an accurate, unbiased picture of how your home performs.
The DOE Home Energy Score (HES) is a standardized home efficiency rating developed by the U.S. Department of Energy. It scores your home on a scale of 1 to 10 — similar to a miles-per-gallon rating for your car.
A Home Energy Score assessment is a practical choice if you want to:
- Understand your home’s overall energy performance quickly and affordably
- Prepare your home for sale or evaluate a home you’re considering buying
- Identify the highest-impact improvements
Home Star Iowa partners with Eastern Iowa home builders to provide the independent third-party energy testing your projects require. Our new construction services include:
- Basic energy code compliance verification (IECC)
- HERS (Home Energy Rating System) ratings and index scoring
- ENERGY STAR for New Homes certification testing
- Blower door and duct leakage testing
We work with builders at every stage — from plan review through final testing — to keep projects on schedule and help homebuyers understand the performance of their new home.
Home Star Training is a nationally active BPI Testing Center offering building science certification courses for energy auditors, contractors, and building performance professionals. Rob Novak has delivered BPI training classes across the United States since 2009.
Current course offerings include:
- Custom training for businesses and organizations in their area
- BPI Building Analyst Technician (BA-T) — the foundational credential for energy auditors
- BPI Heating, Air Conditioning, and Envelope specialty certifications

What Eastern Iowa Homeowners Are Saying
“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 knowledgeable.

Well worth it.”
Doug de Regnier

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, fortunately not too long ago before. It was removed the next day and a re-check found the CO problem no longer existed. Also, I had had a problem with bats. An attempt had been made to seal off all the possible entries which bat could use, but some were missed. Mr. Novak found four more. This was a real bonus.. I am looking forward to a more comfortable home.”
