Save time and Energy

A home energy audit, also known as a home energy assessment, can help you understand the whole picture of your home’s energy use. An audit can help you determine how much energy your home uses, where your home is losing energy, and which problem areas and fixes you should prioritize to make your home more efficient and comfortable. A home energy audit should be your first step before making energy-saving home improvements, as well as before adding a renewable energy system to your home.

A professional home energy audit will provide a thorough assessment of your home’s energy use. In addition to a room-by-room examination of the home, an auditor may employ equipment such as blower doors, infrared cameras, and (rarely) PerFluorocarbon tracer gas.

Thermal imaging

Thermography measures surface temperatures by using infrared video and still cameras. These tools see light that is in the heat spectrum. Images on the video or film record the temperature variations of the building’s skin, ranging from white for warm regions to black for cooler areas. The resulting images help the auditor determine whether insulation is needed. They also serve as a quality control tool, to ensure that insulation has been installed correctly.

Energy auditors may use thermography — or infrared scanning — to detect thermal defects and air leakage in building envelopes.

To prepare for an interior thermal scan, the homeowner should take steps to ensure an accurate result. This may include moving furniture away from exterior walls and removing drapes. The most accurate thermographic images usually occur when there is a large temperature difference (at least 20°F [14°C]) between inside and outside air temperatures.
