A Denver energy audit involves several components:

1. Blower Door Test:AirTight Energy Inspections Include Blower Door Diagnostics

The main component of an energy audit is the “blower door test.” A blower door is a large fan that is mounted into the frame of an exterior door. The fan moves air out of the house, lowering the air pressure inside and forcing air to flow in through all unsealed cracks and openings. Walking around the home, auditors can feel for leaks and/or use a smoke pencil to visually determine leakage. The blower door pressure gauge will determine the amount of air leaking out of the home which the auditor then uses to determine the air exchange rate of the building. The reading on the gauge will be used to determine just how tight or leaky your Denver home is and what improvements are necessary.

AirTight Energy Inspections Include Carbon Monoxide Testing2. Carbon Monoxide Testing:

Every audit includes monitoring the levels of Carbon Monoxide in the Combustible Appliance Zone (CAZ) to determine if there are any leaks present created by the hot water heater and furnace. If not enough fresh air is available for the combustible appliances, Carbon Monoxide can sometimes flow back into the home. Using a Carbon Monoxide detector, the auditor can do an assessment inside the mechanical room to determine if Carbon Monoxide levels are safe. In fact, in 2009 the County of Denver passed ordinances requiring Carbon Monoxide alarms in all residences.

Additional tests check draft levels and for backdraft and further ensure the area is safe and not leaking hazardous levels of Carbon Monoxide into the home. If your CO detector continually goes off, or if you are constantly having to re-light your pilot light, be sure to let the auditor know as these can be indications of problems.

3. Gas Leak Testing :

Using a gas detector, the auditor will check connections where the gas line is connected to the appliances and ensure there are no leaks. If a leak is detected the auditor will alert the homeowner so they can contact their HVAC contractor for repairs.

AirTight Energy Inspections Include Infrared Testing4.Infrared Camera Diagnostics:

Your energy auditor will use thermography—or an infrared camera—to detect thermal differences and air leakage in a home. Infrared cameras allow the auditor to view a thermal image of what’s behind the walls. Thermography measures varying temperature differences using infrared cameras. These tools are able to record light that is part of the heat spectrum. The infrared cameras record the temperature variations in a building’s envelope. The resulting images help the auditor determine where there are leaks and whether additional sealing and/or insulation is necessary. They are also a valuable tool, to ensure that insulation has been installed correctly. (In the picture on the left, the blue parts of the image indicate missing or sagging insulation discovered during a Denver energy audit.)

Infrared scans are a great tool for your auditor to use at the same time the blower door is running. The blower door fan helps exaggerate air leakage as air movement becomes much more apparent in the infrared camera’s viewfinder. An infrared camera used in conjunction with the blower door is a highly effective tool to further zero in on leaks penetrating the home’s envelope through cracks and holes as well as for mis-aligned or missing insulation.

The Denver Energy Audit Process: When the AirTight Inspector shows up at your home, here is an idea of what will take place.

1. First the inspector will sit down with you the homeowner and discuss your home. They will want to get to know your home and how you use it. Do you have rooms that are always cold? or hot in the summer? If you have the previous 12 months of utility bills handy, be sure to let your auditor know so they can make a note of your usage.

2. The inspector will then walk around the home with you so you can point out specific concerns you may have. Is there an area that is particularly drafty? Where is the access to the crawl space or attic? What improvements have you done to the home since you’ve owned it? Where are the combustible appliances located? What type of heat does the home use?

3. Next the inspector will walk around the exterior of your home and look at the overall condition of the home including the walls, roof, siding, and gutters taking into account all the penetrations into the building envelope.

4. Back inside the home, the inspector will head to where the Combustible appliances are located for some initial diagnostics. The appliance model numbers will be recorded, the lines tested for gas leaks and the overall room tested for Carbon Monoxide. The model numbers and year of the appliances will help the auditor determine the efficiency of your units.

5.Next up is the blower door test. Placing the blower door in an exterior door, the inspector will begin to run the blower door fan and digital meter. With the blower door fan running at -50 CFM (cubic feet per minute) the home will be be depressurized with the air being pushed outside the home simulating a 20 mile per hour wind. The inspector will then walk throughout your home and investigate the home for leakage. The blower door dramatically accentuates the movement of air infiltrating your home allowing the inspector to pinpoint precise leakage areas. The digital readout of the blower door will provide the auditor with a numerical figure of the ACH or air changes per hour which will then determine how leaky or tight your home is.

Important: If you have a wood fireplace that is operational, be sure to extinguish all ashes 24-48 hours prior to your energy audit and remove any ashes from the fireplace. The blower door fan can ignite the ashes and/or blow them throughout the home.

6. Using an infrared camera, the inspector will then scan the walls of your home and look for further signs of air penetrating the envelope as well as any indications of misaligned insulation, missing insulation and signs of moisture. Together with the blower door, the infrared camera allows your inspector to see much more detail in the envelope. Knee walls, cathedral ceilings, skylights, soffits — are all areas that an inspector will want to take a close look at with the infrared camera for signs of poor insulation.

7. With all the data gathered, and with information in hand, the auditor will put together a comprehensive report detailing the energy efficiency of your home which will be available to you within three business days. The report will feature recommendations for improvements with the cost estimate associated with the improvement as well as the Return on your Investment (ROI) you can expect for that improvement.
