Our Home Energy Audit process:

Step 1: A professionally trained home performance analyst will visit your home to conduct a thorough home performance client interview and comprehensive analysis of your home. We will ask a series of questions relating to the comfort, air quality and energy usage in your home. For us to provide a comprehensive energy analysis, please be prepared to provide 12 months of past utility bills.

Step 2: Once the interview is complete, we will perform a visual analysis and thorough diagnostic testing of your home that will take approximately three to five hours. The testing includes:

I. A visual inspection to spot existing and potential problems with damaged or malfunctioning mechanical systems or building components including:

  • Inspection for possible mold and moisture sources.
  • Levels of insulation in the attic and crawl space.
  • Potential indoor air pollution sources.
  • Exterior shell inspection for problems such as cracking paint, cracked plaster, dry rot, and roof problems.
  • Exhaust fan ducts such as bathroom fans and dryer vents.
  • An assessment of lighting and electrical components.

II. A combustion safety test including:

  • Gas leak detection near supply lines, where the pipe enters the building and at the gas meter.
  • Carbon monoxide levels in the flue gases of the heating and cooling system, water heater, gas range, and oven.
  • Carbon monoxide levels within the ambient air of your home.
  • A drafting test to evaluate the risk of combustion gases being pulled back into the house by negative air pressure.
  • Efficiency test of the heating and cooling system, gas appliances, and water heater.
  • Flue inspection for blockages, breaks, or other safety concerns.

III. A full diagnostic test using home performance equipment to quantitatively test the home for air leakage and ventilation issues including:

  • The use of an infrared camera to spot missing or improperly installed insulation.
  • The use of digital pressure gauges and a blower door to identify air leakage paths through the attic, walls, and crawlspace.
  • The use of a duct blaster to identify leaks within the heating and cooling system.

Step 3: Once we have finished the testing, we will deliver a full comprehensive digital report including our findings and recommended repairs. At this time, we will also set a meeting to later discuss the report and any questions or concerns you may have. After reviewing the report, we will design a specialized and cost effective fixed-price contracting plan specifically for you. Here are some examples of items often included within the scope of work:

  • Air sealing the home.
  • Moisture barrier in the crawlspace.
  • Insulation in the attic, crawlspace, and walls.
  • Energy Star appliances.
  • Low-flow water fixtures.
  • Efficient lighting and energy saving devices.
  • On-demand re-circulating water pump.
  • Energy efficient windows and doors.
  • Thermal and PV solar system.
  • Energy efficient water heater.
  • High efficiency heating and cooling system.
  • Mechanical filtered fresh air ventilation.
