On the right are two infrared images of the same window, the bright red color indicates heat loss. In one image the window is not covered, in the other, an insulating drapery has been installed. The images make it clear and easy to see heat being lost where there is not sufficient insulation. During cold weather months, 40% of heat in the average home escapes through under insulated windows.
This winter, Schools for Energy Efficiency® (SEE) has provided our district with a thermal infrared imaging camera for checking building envelopes and locating the source of any heat loss in our facilities. The camera can also be used as a great visual activity for students. If you would like to check out this tool in your building or have the Energy Efficiency Coordinator visit your classroom, please contact me via email firstname.lastname@example.org or at ext. 8104.
