Thermal imagery is an intelligent spatial information data layer which can identify heat loss from buildings. In January 2014 Harrow Council undertook a survey at night, with the use of a plane to analyse how much heat is lost from buildings in Harrow. This was to support the loft insulation and other environmental schemes in Harrow.
The information has been analysed to support work in the council and has also been made available to the public so residents, schools and local businesses can benefit from the information also.
You can view the results of the survey in the find section. It will show you if an address has above or below average heat loss. This can be useful for determining how well roofs are insulted and if installing insulation would be beneficial. It should be noted that with surveys of this size, some errors may have occurred and the data has been generalised before being released.
