Nature in the city and the League for the Protection of Birds

The energy and environmental regulations for new buildings, known as RE2020, aim to respond to energy and climate issues. However, it is important to take into account the collapse of biodiversity denounced by the latest report of the IPBES - Intergovernmental Platform on Biodiversity and Ecosystem Services. Species that shelter and reproduce in buildings, such as birds, bats, some reptiles and insects, must be preserved and their reception can be encouraged in new constructions.

Indeed, these species nest, reproduce or shelter in our buildings (e.g. cracks, unplugged joints), in cavities (e.g. bolt holes, shutter boxes under tiles) but also in attics and cellars when an access exists. In France, black swifts now breed almost exclusively in buildings.

The preservation of these species is therefore dependent on the maintenance of this particular habitat. However, suitable cavities are progressively disappearing: renovation operations; thermal insulation from the outside blocking cavities; destruction of old buildings to make way for new buildings that are more energy efficient but smooth and therefore not very welcoming for wildlife.
