This winter, small twin-engine aircraft, equipped with powerful infrared measuring devices, will fly over the entire province of Walloon Brabant at nightfall. The reason? To highlight the amount of heat loss via roofs and raise awareness among the public and businesses through "aerial thermography".
Flights began on December 20 and will continue until the end of January 2023 weather permitting. The devices will scan more than 40 square kilometres of territory per hour. The measurements will be taken at the beginning of the night, at the time when the majority of homes and other buildings are still heated.
After processing, the data will be returned to the municipalities and the departments responsible for ensuring their dissemination to citizens and businesses.
The project is being coordinated by in BW - the intermunicipal association of Walloon Brabant, and is the first on this scale in the region. Almost all of the Flemish and Brussels territories have already been subjected to such aerial thermography.

In Wallonia, these have so far been isolated initiatives. The in BW approach – largely subsidised by the Walloon Region and to a lesser extent by the province of Walloon Brabant – is therefore original and allows for solid economies of scale. The municipalities will pay a maximum of €3500 to obtain the data concerning them.
The images are considered to be private data, and as such, in BW ensures that their use meets all the criteria referred to in the GDPR, the General Data Protection Regulation.
This thermal mapping is fully in line with the 2023-2025 strategic plan of the Walloon Brabant intermunicipal association, which enshrines sustainable development on the one hand, and the intercommunality of the territory on the other.
