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 uninsulated windows.
For the rest of this month and into early March, Schools for Energy Efficiency® (SEE) has provided our district with a thermal infrared camera as a great visual activity for students. If you would like to check out this fun tool and have the Energy Efficiency Coordinator visit your classroom, please contact me via email or at extension 60051.
