Really like this idea, caught by Nicolas Roope at Poke, and implemented by Haringey Council in London, for a heat map that allows you to tell at a glance whose house in your area is emmitting more or less heat. Red = hothouse. Blue = Koolhaus. Quickly pinpoints the spots using more/less insulation.
“Set up to embarrass residents and businesses into sorting out their insulation the test borough Harningey happened to feature my gaff as seen above which seems to be somewhere in the middle between good and bad.”
