A Belgian program called, 'Zoom Into Your Roof' uses infrared energy maps to identify heat-leaking structures in need of better insulation.
The 'Zoom into Your Roof' thermal map is a joint project of 21 cities and municipalities in the Antwerp region of Belgium. The map drills down from community to postal code to street and number. It also has a slider that allows viewers to see a thermal view or an aerial view. The thermal view gives an indication of rooftop heat loss at the time photos were taken. User information is further enhanced by answering a series of questions.
