CHP provides a full array of integrated building diagnostic, forensics and performance verification testing services. Our expertise will support your goals for a building that has maximum comfort, health, safety and energy efficiency. With more stringent energy efficiency codes building diagnostic and verification testing is an essential component in residential and commercial construction. One of the most valuable uses is for building forensics to determine exact locations and causes of building envelope failures: air leakage pathways, flawed insulation, and water damage.


  • Infrared Thermography (IR Scanning): Used to verify performance of insulation and air barrier controls through out building envelope; determine thermal by-passes and trace water damage.

Diagnostic Equipment

Infrared Camera:

Used for inspection of building thermal envelope control layers. Primary control layers to inspect for operational integrity are:

  • air barrier
  • insulation barrier
  • moisture/vapor barriers.

Lathe and plaster wall with no insulation.

Each control barrier must be continuous and contiguous to each other throughout the building envelope that separates conditioned indoor air from ambient outdoor conditions. Other critical applications are:

  • targeted inspection of flat roof leakage pathways.
  • targeted inspection of hydronic pipe leaks in radiant floors.
  • Quality control and verification of effective installation of insulation throughout job sequencing: pre – intermittent – post completion.
  • Stretch Code compliance and HERS rating verification and inspection of the thermal envelope air barrier by-passes.

We use Flir IR cameras

I’m happy that the incentive was more than anticipated (As a Home Performance Contractor with Mass Save Cozy Home secured $2,760 in project incentive funds.). I enjoyed working with you and your crew. Everyone was pleasant to deal with. They were professional and courteous and when I had questions, the answers were in a non-technical response so I could understand. Each day they left the area clean.

Someone from the utility company was here today to inspect the work resulting from their incentive. They were very positive both about the quality of the recommendation, and the quality of the work. I am pleased too. I’m almost looking forward to next winter to see the difference.

The house definitely feels different – hard to explain the feeling, maybe more solid? Anyway, we have checked out all the work areas that we could and are really impressed. We can already feel the difference in some rooms – even with the warmer weather! Thanks to all the guys who were at the house. They were all very polite and pleasant and seem to have done an awesome job!
