Infrared Inspections are rapidly becoming the norm for building inspections. With the proper tools and training, building inspectors can practically eliminate energy loss due to inefficient or poor construction. Infrared inspections help to reduce the carbon footprint of a building, protecting not only the environment, but reducing energy costs while increasing safety, productivity and energy efficiency.
An infrared energy audit is a detailed look at the energy leakage throughout a home or commercial property. The entire property is examined using thermal infrared imaging to pinpoint air leakage, missing insulation or poorly insulated areas in floors, ceilings and walls. Examiners produce a detailed written report that shows where problems were found, along with recommendations on what should be done to address each issue. In most cases, this will result is reduced energy consumption and lower heating and cooling bills.
Thermal infrared imaging has become a valuable tool in performing energy audits for both residential and commercial buildings. The infrared camera has the ability to display heat as a visual image, making it easy to see where energy is being wasted. These images are included in the energy audit report, giving a side-by-side comparison of standard room pictures and the thermal imaging picture so that the reader can see exactly where the energy loss is occurring.
Thermal infrared imaging helps detect several common energy problems. Proper thermal insulation in buildings is an important factor in achieving thermal comfort for its occupants. Insulation reduces unwanted heat loss or gain and can reduce the energy demands of heating and cooling systems. The infrared image below shows missing ceiling insulation, whereas the digital image on the right does not reveal any problems.
Air leakage is another major problem that infrared imaging detects. This occurs when outside air enters a house uncontrollably through cracks and openings. By sealing such cracks and openings in your home, you can significantly reduce heating and cooling costs, improve building durability and create a healthier indoor environment.
Air tightness measurements
In order to determine if a new building is properly sealed, perform a pressurisation test. This test must be run before the airtight layers have been covered and while it is still possible to take action to seal any leaks. Carry out blower door testing to check building tightness and air infiltration. Use a duct blaster to test the building's HVAC system to locate air leaks in the duct system.
