Building Investigation Using FLiR Thermal Imaging Cameras

5 Tips to use your FLIR Thermal Imaging Camera for Building Inspections

Did you know that building that we stay can poses threat to human health? Yes, it is, because of the exposure of hazardous agents such as biological contaminants coming from mold and fungi. The issues are, where this fungus and mold come from?

One of the scientific explanation of this issues due to the water intrusion coming from the broken pipe, damaging the insulation on a wall and poorly ventilation of air. This issues can be mitigated and address early by looking into problematic or possible problem areas using thermal imaging cameras. What is thermal imaging camera? Thermal imaging camera is a camera that equips with an infrared sensor, these infrared sensors contain different wavelength as compare to the natural light wavelength.

As result, the physicist can manipulate the application of this infrared camera into a plotting dots and combine it together to form a map. This map further translated into a picture which can be recognized by naked eyes. There are many types of infrared or thermal imaging camera which can be classified as their resolution, same as a normal pixel in a standard camera.

Nowadays, using this technology, building inspector enable to detects leaks, broken pipes and poor insulation in a house or building to be rectified. Now, the FLIRONE, for example, is the simplest accessories that can be used for a building inspector to investigate the problem in a building. During initial walkthrough survey in indoor environment investigation, the inspector can use this thermal camera, to detect the leak based on the differences color projected in screen and thus spotted the area that needs to be fixed.

By using this FLIRONE thermal imaging camera, the inspector can save their time and money in the building investigation. There are 5 main areas that need to be inspected by building inspector before they can resolve the indoor environmental problem. Example of the areas are:

  1. Window and doors that connected or attach to the outside element
  2. Walls typically attach or suspected to have connection with the water pipe or electrical wire
  3. Ceiling that attaches near to the edge of a building (to spot any water intrusion due to roof leak and other broken ceiling attachment)
  4. Ventilation duct/ system associated with the air movement within the indoor environment
  5. Floors near the source of water such as kitchen, bathroom and their nearest location

Previously, based on professional experience as an indoor environmental inspector, the thermal imaging camera can help us in determining the problematic areas by focusing on the temperature differences shown by the camera. Further investigation and protocol will confirm that location as problematic or not. This includes the moisture mapping survey, taking the moisture and RH reading and air quality samples. In conclusion, by using the infrared camera, an inspector can focus on the mitigation of the problematic area. Example of the thermal imaging camera can be found below (please click below image for more details).

After identification of damage areas, inspector then can suggest the immediate plan of action to contain the areas and rectify any damage to prevent the moisture content to be a source of microbial contaminants to growth.
