The Victoria Regina building was built between 1974 and 1978 as office space for IBM. The recognisable façade design clearly shows this history. The building is located in the Northern Quarter of Brussels next to the botanical gardens.
The current owner wants to renovate the building keeping the old building structure and fitting it with a 21st century-proof façade and mixed-use. Part of the renovation is the addition of a roof top bar with an outdoor seating area. Also several new entrances on ground level will make a connection to the public outdoor space.
Both the new façade, the roof top outdoor seating area and the entrances will be influenced by wind. In the first case it is wind loading that is of interest. For the outdoor spaces it is the level of wind comfort. Both questions desired a different approach.
