Paragraph 1: Buildings

Roofs and terraces, walls and their renderings, partitions, ceilings, floors, windows, skylights, doors, meter locations and pipe and network ducts are regularly maintained to prevent water seepage and fumes, while respecting essential ventilation systems. Grids, grates and skylights are cleaned and checked to ensure that they fulfil their function at all times.

Green walls and roofs are designed to prevent plants and their containers from falling over, openings from becoming blocked and any excess humidity that could create the risk of short circuits or encourage the proliferation of animals that are harmful to human health, as well as the appearance of mould. They are regularly cleaned, maintained and inspected.

The demolition of a building is preceded by a rat and pigeon control operation. If this demolition reveals the presence of dangerous solid or liquid products, in particular vats or tanks containing flammable or toxic liquids, it is halted until these products are removed and the installations are neutralised by decontamination or removed.
