Building for a better tomorrow.

elements of an audit

During the three to four hours we spend at your home, we will complete a number of sophisticated tests using specialized equipment as well as visually inspect some key areas of your home. You are welcome to join us for the inspections (some customers get a kick out of seeing how this works!). Or if you prefer, we can limit your involvement to just the start and end of our time at your home.

air leakage through your building envelope

We will safely pressurize your house to find out where air is leaking. We will quantify the effective size of your total air leaks and identify where the most cost-effective fixes can be made. Some customers have combined air leaks the size of a big window! Whatever size your combined leaks compare to, it’s like having a window of that size wide open day and night while you try to heat or cool your house. This test is performed using a blower door, specialized software and an infrared camera.

duct leakage

We will safely pressurize your duct system to quantify how much of your heated or cooled air is lost through the ducts. This test is performed using a duct blaster and specialized software.

historical energy assessment

We will assess your historical energy bills to demonstrate your your baseline energy use and show you your heating and cooling costs on top of your baseline. This will enable an assessment of potential savings through improving the energy efficiency of your home.

attic and crawl space inspection

Since hot air rises, attics often represent a significant loss of heated air. As air leaves your attic, it draws up air from below, which can then pull in cold air through leaky areas lower in the house or from the crawlspace. We will inspect your attic and crawl spaces to assess air loss, insulation quality and identify potential air quality issues.

Depending on when your house was built – especially if it was built before the days of HVAC when it was more important to allow free flow of air to avoid moisture build up than to seal to keep in heat – the way the main structural walls and the attic are constructed may make a difference in how air flows through your house.

insulation efficiency

We will do a combination of visual inspection of your insulation and assessing insulation efficiency using an infrared camera to help ‘see’ behind closed walls. This will help us rate where your insulation is of good or poor quality and where we recommend you make improvements.

HVAC inspection

Your heating and cooling systems will be inspected to assess leakage and proper functionality. The heat exchange will be inspected for cracks. We will inspect to ensure proper insulation and sealing of joints.

hot water heater inspection

We will assess your hot water heater for potentially dangerous carbon monoxide leakage.

lighting energy assessment

We will assess your lighting energy use and recommend how you can make improvements.

appliance efficiency

We will assess your appliance efficiency and recommend how you can make improvements.
