Zoom into your Roof: Checking the Thermal Performance of Homes

[H]ow can individual citizens determine whether such a costly renovation is worthwhile for their own house? The online project “Zoom into Your Roof” [antwerpen.be] tries to help solve this question through a relatively simple visualization. During the winter of 2009, a small airplane with an infrared scanner made a wide sweeping thermal scan of a large part of Belgium, which resulted in the largest thermographic map currently available online. Inhabitants living within this area are able to select their home address and answer a few questions (such as the angle of the roof). in order to determine for themselves how their own roofs actually perform.
