Text description provided by the architects. The client's great vision: an important socio -economic and cultural actor. The administration of the province of Namur has almost all of its services in a new building, the “map” built in Salzinnes. As the province of Namur on the outskirts and along the Sambre river instead of a clearly visible location in the city center, it takes up a strong and thoughtful attitude and reflects its vision of its role. The tender specifications for the “Design & Build” project required exceptionally high environmental standards, including BREEAM certification. These requirements were reached on a “outstanding” level with a score of 93.53%.
The building is a large rectangle with a measurement of 106.2 MX 61.65 m and is organized by eight rectangular courtyards on two levels. Thanks to 74 chimneys on the roof in the entire interior, this layout ensures the entire interior. The building is only made of wood, with two steps of 3.6 m high and resting on stilts and a network of galvanized steel beams with hot tip. The four facades have a quiet variety of pillars and floor -to -ceiling windows. The collaborative approach of the architect and the active participation of all participants (including the general contractor) from the early design phase enabled the realization of innovative suggestions as long as they were motivated by sustainable and rational design principles.
The card offers a particularly comfortable environment for body and mind: *plenty of natural light due to high ceilings (3 m) and narrow floor panels (8.10 m and 12.15 m). *Exceptional air quality, which is achieved by a natural ventilation system, combines the adjustable chimneys on the roof with window ventilation. *Controlled acoustics thanks to cellulose-based ceiling insulation and a balanced mix of heavy and light materials in the wooden floors. *Easy access for pedestrians and cyclists, including a new external elevator, which is connected to the existing bridge over the nearby railway line. *A significant part of the surrounding garden is dedicated to growing vegetables, partly by a concessionary company and card staff. Generous natural lighting, LED lighting and the natural ventilation system significantly reduce the energy requirement. A deep geothermal system and cooling system as well as solar modules on the roof provides the required energy. Water consumption is minimized by the use of sanitary devices and leak monitoring systems. Rainwater is collected completely and reused for toilets, the outer fountain and the irrigation of green rooms. Excess rainwater is infiltrated in a wadi and a pond, which improves and structured the garden.
The use of reusable and recyclable materials, resilience measurements, modularity, material effect strategies and sustainable materials from the region was an essential part of the project design: *The stilts increase the building to protect against potential sambre flooding. *The structure (load-bearing pillar, floors and roof) consists exclusively of local softwood (solid wooden box systems and robot-assema-OSB panels). *The facade cladding (pillars and falls) is made of poplar wood, a low -quality local wood, which is highly lived by thermal treatment. *The external adjustment is equipped with clear double glazing, which are slightly recyclable due to the lack of filter layers. *The outer staircase and the canopy consist of thin profiles and perforated galvanized steel plates that are designed for the maximum material efficiency. *The acoustic absorption on the floors is achieved using a sprayed cellulose insulation. *The increased floor covering is covered with oak parquet and naturally pigmented linoleum.
The strict modularity of the building ensures material circularity, the reduction in waste and future adaptability to climatic and functional changes. In addition, the general contractor pursued a very responsible approach to building waste management and derived over 95% of the waste from landfills.
