In a booming neighborhood, school and a new passive housing have emerged. The project was conducted in design-build team with ambitious sustainable goals. The school can accommodate 490 children, in new buildings and parts of buildings renovated. 51 units complement the whole. This project was devoted Exemplary Building 2011 by the Brussels region.
History of the draft
The Brussels North neighborhood is known for its multisocial frame. A place where men and business women alongside the students. A social melting pot where different cultures intermingle. In the heart of this diversity is that primary school 'The Helipad'. See a construction project at that location is not a surprise. The area has a high population density and dire need of new housing. At present, there is not enough land to meet the huge demand. An increase in population also means more children and young children, who naturally require access to education.
Urbanity
Previously, the island was not closed and urban structure is found in weakened. On the other side of the street Simons, new homes were built recently. Housing project will create a vis-a-vis to make his character to the street.
Overall, the implementation can close the island and thereby make it more legible urban structure. The project links the various functions required and is treated as a coherent whole. However, access and circulation allow a different use, specific to each program.
The templates of the new buildings are the same as those of neighboring buildings:
Ground + 1 for new school buildings and co-inviting local,
+ Ground + 4 penthouse setback for housing.
The island is closed and legible while keeping variable heights that create breaths in the urban landscape.
Moreover, existing buildings were in great need of renovation. Dilapidated school buildings were a sharp contrast to the newly built apartment building across the street Simon. Before the renovation, the former primary school building 'L'Heliport' was divided into two blocks. A Nicolay on the street and the other on Avenue Heliport, who was shot to make room for new construction. The Nicolay Street Building was renovated and integrated into the new school building. The new school building is included in the lower part of the complex and occupies only a part of the area of the building block. Architecturally, the volumes and the façades are treated differently and identify each part while maintaining overall coherence.
Next Regional PPAS (specific plan of land use) plans imposed a large concentration of new construction, but they are biased to the quality and usability. A balanced implementation has led to all buildings in value. The school has become a kind of 'walk', where dining halls, gym and classes form a meeting place. An ideal space for residents and locals, to organize events.
Simons-Anvers'renforce and the social fabric. School life adapts to daily activities and not the reverse.
Habitability
The site is located in a very mixed social environment of great cultural richness. The project wanted to respect and emphasize the diversity enliant various programs and responding to different needs of the neighborhood.
The school welcomes students from raw to primary reception classes. The gym, two dining halls and the playground can also be used on evenings and we regularly or for special events. These spaces create new meeting places for the neighborhood.
The 51 units are distributed as follows: 3 studios, four 1-bedroom apartments, 30 2-bedroom apartments, 11 apartments 3 rooms and 3 apartments 4 rooms of which 2 have been adapted for disabled people. In this way, the new building can bring together people of ages, cultures and different profiles. The new apartments develop spatial quality in all his aspects: functionality, architectural quality, natural lighting, acoustic performances and, of course, thermal performance. Almost all apartments are equipped with windows to front and rear and all have an outdoor space in the form of a garden, balcony or terrace. The common areas are emerging as a meeting place for residents and, in a broader sense, to the local residents. The new complex also has a reception function for children. This space is tailored for children.
Durability
Priority was given to a sustainable approach to architecture and technical construction.
Envelope and technical
To limit the heat demand of the building, the walls will have a thrust insulation. Windows, meanwhile, will include a glazing of a U-value of0.5 W / m². K. Energy saving is further enhanced by heat distribution system properly developed, powered by 200 square meters of thermal panels and supplemented by more gas condensing boilers small format.
Biodiversity
The natures'invite including through 900 m² of green roofs, plus 945 sqm garden in the ground for good infiltration of water pluie.La high capacity rain barrels will be almost sufficient to supply toilet .
Material
The project includes more than 50% sustainable materials classified under 3 as the Nibe. All finishing materials are environmentally friendly. For the choice of materials, the impact on the environment and health was predominant. He was also selected in the research project PassReg (www.passreg.eu) as a pilot project for the dissemination of liabilities and sustainable Europe.
Water
All rainwater arriving on non-accessible roofs is collected in recovery tank. School health work with rainwater via rainwater tanks in ordinary concrete.
6 concrete tank of 20,000 L / pc (000 liters or 120 in all) are provided for all.
Comfort and health
The passive standard offers unparalleled comfort: by simple physical principles, a pleasant temperature of air and walls is ensured, and a constant air renewal.
Comfort, but also real psychological occupant is essential. So the project meets the standards of comfort for both acoustics, as heating or ventilation, but attention is also paid to the empowerment of the personal environment.
The health level, the double flow, used properly, can prevent a number of pollutants and maintain a good quality indoor environment
Acoustic
At the school level, various acoustic panels are planned in noisy spaces (dining halls, gym, ...).
Inside the building:
The project includes the establishment of technical installations low noise, acoustic insulation of ducts and false ceilings.
All utility lines will be closed by masonry blocks.
Compared to external disturbances
No special action is taken at the outer envelope level, however thanks to passive criteria, measures are taken logically, as the introduction of triple glazing significantly reducing outside noise.
Repeatability
The casing is constructed with blocks of sand-lime, insulation and enduit.Seule the thickness of the insulation (30cm) differs from the traditional design. Doors and windows are made of wood profiles (PEFC) aluminum covers. The completion is done with materials such as plaster, sheetrock, linoleum, tile, ... Although the heating and ventilation are provided by a recent type of equipment, installation is based on techniques already known as the heat exchanger, solar water heaters and fans.
In other words, materials and implemented hardly differ from a traditional site. No materials found or techniques that people know not practice. Anyone can do it. The processes and materials are well known to all.
Budgetary aspect
The project is built for all budgets in of € 1,100 / m², or 10% less than a standard project. For information, the average price during the submission of bids was € 1,500 / m²! And only 4 proposal reached the passive standard, but not by more expensive elsewhere.
Special techniques comply with the same desire for simplicity and sustainability as the overall design. The structure is optimized taking as a basis the mass necessary for acoustic, which implies a minimum slab thickness. This then induces an optimal thickness range, used for the entire project.
The Brussels-Capital Region has praised the energy performance and design of the project. These congratulations come back mainly to the collaboration between the different parties involved, which have consistently sought the most relevant solutions.

Building users opinion
The school opened its doors and housing begin to be inhabited.
If you had to do it again?
The tender in Design and Build has shown that program presqu'équivalents templates (the area is strictly defined by an Individual Assignment Soil Map), it is possible to build quality passive buildings reasonably priced. Of all the projects submitted, only 4 have proposed the passive standard, and it was not the most expensive, far from it. This procedure helped launch an attractive project in this developing area.
