In the technologically evolving construction sector, advanced equipment is increasingly being used to gain a better understanding of quality and living comfort. As far as we are concerned, the usefulness of a thermal imaging camera in the building sector can certainly compete for the title of the most versatile measuring instrument in construction. A thermal camera displays the thermal ratio of materials in a thermographic image. The science of interpreting these images correctly is called thermography. Of course, there is a wide variation in the quality and accuracy of thermal imaging cameras, but let’s briefly touch on a few points for which a thermal imaging camera can be used.
Insulation of buildings
When there is sufficient thermal variation between the outside air and the inside climate of a home or building, a thermal imaging camera is able to visualize the thermal transmittance across the building envelope.
Visualizing thermal bridges
When there is sufficient thermal variation between the outside air and the indoor climate of a house and for a sufficiently long time (preferably 48 hours or more), the thermal loss can be visualized with a thermal camera. The loss of heat through conduction can cause both an unwanted cold air flow and condensation problems resulting in mold.
Use of a thermal camera in HVAC applications
Optimizing the indoor environment starts with a proper survey of the heating system. Are the radiators performing as expected? Is the underfloor heating providing the necessary heat? Where are the water pipes located in the building? Is the entire space heated as expected? Are there any blockages, and if so, can we locate them? Is the water heater performing as expected? A thermal imaging camera can give you a way out in many situations.
Detecting moisture leaks
Moisture leaks almost always involve thermal differences. Either the water retains heat longer, or it takes longer for the volume of water to heat up. The evaporation effect of moisture is also nicely visualized with a thermal imaging camera.
Detecting air infiltration
The infiltration of cold air into a house can be done in different ways. It is important to detect the unwanted infiltration in order to reduce energy costs and possible condensation problems. This unwanted infiltration can occur due to pressure differences, wind, use of ventilation systems, use of an extractor hood, etc.
Is your solar panel installation not performing optimally?
Cells that do not conduct properly create resistance in the panel. The resistance created can be seen with the thermal imaging camera because of the heat it creates.
By conducting the cell on the glass, we can get a picture of any problems with an installation. Many problems can occur such as, broken cells, mismatching of the cells, damage caused during installation: shadow effects, problems with diodes, PID (potential Induced Degradation)…
Inspection of the fuse box
Electrical overloads and transition resistances are some of the problems that can occur in a fuse box/power cabinet. Industry benefits greatly from carrying out such inspections on a regular basis. But it can also be useful for building management to visualize the thermal relationship.
Which thermal imaging camera to choose?
There is a wide variety of choices for a thermal imager. Some things that can affect the quality and price of thermal imagers:
- Resolution of the thermal sensor
- Sensitivity of the sensor
- Possibility to replace lenses
- Different lenses for optimal spatial resolution
- Automatic focus
- Software features
- Rotatable lens
- Software packages – A lot of reporting requires solid software
- DON’T FORGET THE TRAINING!
