Building physical data

The programme of De Meander comprises offices, reception rooms, auditoriums, information and exposition space, a lounge, a restaurant and an underground car park with 2 parking levels. With a view to an attractive work environment, the architect chose to design a building of no more than 6 floors. The volume starts at the Brussels Canal as a horizontal low-rise building and ends in a 60 m high tower. This should make the building a distinguishing element in the Brussels skyline. The building has a sustainability level of 4 stars by the standards of the 'Handboek waardering Kantoorgebouwen' and an E-level of only E34. This complies with the Flemish definition of an almost energy-neutral (BEN) building. It is a passive building design that meets the standards for passive building implemented in 2015 in the Brussels-Capital Region
