Bockstael - 10.069
Structural engineering mission for the execution phase only.
Construction of the new primary school "Emile Bockstael" in the region of Heyzel in Brussels. The school is a passive building of two floors over a ground floor, and covers a ground surface of about 1200m². The structure is made of timber and rests on foundations made of concrete. The class and activity rooms are distributed around a central patio.
In order to achieve the passive energy standard, the project includes a geothermal network as well as an earth cooling tube network burried under the bottom slab. The building is entirely constructed out of visible timber : the floors and walls are made of cross-laminated timber panels and the beams are in glu-lam or massive timber. The top floor is covered by a green roof which also includes photovoltaic panels. The low quality of the soil and the continuous insulation under the building imposed a particular foundation system : excessive settlement is avoided by using a buried concrete slab that rests on piles. The space between the building's raft and the buried slab is used for the distribution of technical services.
The projet was awarded a subsidy from the IBGE (Brussels Institute for Environmental Management).
