NATURE
function of the building: Youth Center how many users: 300 total m2 : 3711.4 m2 total m3 : 28759.95 m3
The network suggested by the design is hold by a green line of trees and greenery which will connect different spots with adding value to the city and neighborhood as well.
CONTEXT
ECONOMY
Address: Wondelgemstraat Existing situation: Sint-Jozef Church
The design approach is to guide the youth of new comers and current residents of the neighborhood with an education which can help them with more handy stuff such as arts and crafts, and will bring new possibilities for the people who don’t want to gain an academic degree to find suitable jobs in future.

THE YOUTH CENTER The church of Sint Josef is located at the core of the neighborhood of Rabot. Rabot is a triangular neighborhood northeast to the center, about 15 minutes walk from it. It is quite well connected by public transport to the other parts of the city. Here, a vast multicultural community inhabits the place and sees as main gathering places the front of the church and the main street, Woldenghemstraat. At any time of the day, the place is very active and you can see the younger ones hanging out, the adults shopping and the older gathering. There is a strong sense of community among some of the multicultural groups, but not all of them are interacting. The Belgian community for example does not mix with the other cultures a lot, as well as others. Moreover there is a current state of chaos on the main street, mainly caused by unmanaged traffic and pedestrian flows. The aim of the project is therefore to bring the inhabitants of Rabot altogether in a place they can identify with and that can be a reference for them, starting from the youth, which we see as the future of the neighborhood and as potential mediators among adults. As the Sint Josef church will be deconsecrated in 2017, this would be an excellent place to take over for a youth center, but also a green energy producing gym, that will host everyone who is willing to work out and some quiet areas to study together with a cafeteria where the community is also welcome.

Q = flow rate in cfm, Cd = 0.65 (for unobstructed openings), A = opening area, square feet, Ti = indoor temp (Rankine), To = outdoor temp (Rankine), Hn = height of "neutral pressure point" (for simple systems, assume 1/2 way between top and bottom openings). Hb = height of bottom opening g = gravity.
