New Shopping center Tournai secured with confidential Keller Smoke- Exhaust Ventilation system.

“Les Bastions” is a shopping center situated in Tournai”. The shopping center was built in 1979 and needed a major renovation.

In March 2015, the renovation and expansion started. The works at “Les Bastions” include a thorough renovation of the existing shopping center, an innovative expansion and the realization of a sustainable retail park on an adjacent parcel of land. It has become a modern and attractive complex that has retained its charm and character. The shopping center has been expanded by 10,000m² and now has 15,540m² of rental surface area.

In total there are 56 stores and catering business located in Les Bastions. The existing outdoor parking places are partially replaced by an underground parking area with two floors and a capacity of 1,260 parking places.

Through various lifts and escalators, this parking gives the visitor direct access to the new shopping gallery. The new public space between the shopping center and the retail park includes large green areas, entrances and exits of the parking area, cycle paths, pedestrian zones, parking places, a bus stop, bicycle racks and water features.

Fire protection for shops and parking

For this large conversion and expansion, Keller Benelux (Lybover Fire) was responsible for the design, delivery, assembly and commissioning of the smoke and heat extraction installations for the underground parking places and the above ground shopping gallery. In addition, a few stores were provided with fire doors, burglary gates and smoke screens.

Smoke and heat extraction installations of underground parking

The smoke and heat extraction installation has been designed and functionally tested by means of a CFD (Computational Fluid Dynamics) simulation at the different levels of the parking area. In total there are 6 blowout ventilators with a diameter of 1.6m and a total capacity of more than 600,000 m³/ h installed. Initially eight ventilators were foreseen, but thanks to the CFD simulation, we were able to reduce this to six ventilators.

To ensure a pleasant air quality in the parking area, 26 thrust-ventilators were also installed including a CO-detection installation. The system provides various synoptic signs to visualize the location of the seat of the fire for the fire-brigade.

Fire protection shops

Keller Benelux supplied a supermarket with two fire shutters. In the event of a fire alarm, these fire gates close the shop so that the fire cannot spread any further and people can leave the shopping arcade in a safe and quiet way.
