AEROPOLIS II

Programe: Construction of an office building and plaza avenue Britsiers in Schaerbeek.

About: AEROPOLIS is an urban UFO. But its compact form sits squarely on street alignment south just to show it does belong there, discretely steps back west liberating a sunny plaza like a breather off the busy boulevard, and humbly aligns its cornice levels with the massive KINETIX next door. The resulting built form wraps itself around a federating patio ensuring optimal daylight entry for all occupants. So it is a respectful UFO.

AEROPOLIS is also an eco-ovni, being at design stage Europe’s largest passive office building, Belgium’s largest when finished. Environmental concerns were an integral part of the client brief at competition stage already, so from the onset priority was given to investments and construction principles reducing energy consumption and the use of non-renewable resources. Highly-effective thermal insulation and efficient natural and forced ventilations help reach these goals.

The compactness achieved limits façade surfaces, thus lowering thermal loss. The main load-bearing structure is bare pre-fabricated concrete, for its thermal inertia. Façade walls are composed of one-story high pre-fabricated timber frames of two types, opaque or glazed, of variable widths allowing them to be placed according to the varying organization of office spaces on each level … the resulting hopscotch of solids and gaps amplified by projecting volumes incorporating the automatically-opening ventilation frames.
