Thermal Imaging Case Study of ASSA ABLOY Doors at Earth Rangers Centre

It’s common sense that a building’s envelope plays a major part in the energy use and thermal comfort of the building. Fortunately, there are many things you can do to maintain and improve the integrity of your doors, windows and insulation systems.  This type of maintenance can be much more cost effective than replacing mechanical systems with higher-efficiency units.

The Earth Rangers Centre recently addressed this type of maintenance when working through the LEED for Existing Buildings: Operations and Maintenance certification by performing a thermal scan of the building. Gratton Infrared, certified thermographers, took images of the exterior of the Earth Rangers Centre with an infrared camera. This camera recognizes temperature differences and shows them in a colour scheme that can be interpreted as heat loss (or gain). Note that interpreting thermal images takes experience, as some images show colours/temperatures that don’t seem to make sense. This can be a result of reflections, camera angle, outdoor conditions and other factors that the thermographer can identify. In some cases, the thermographer will adjust the scale of the temperature gradient to be able to visually identify all the elements in the image.
