1990 to 1993

Arena genève

Located in Geneva, the Arena is a multi-purpose venue that opened its doors in 1995. This hall hosts concerts and sporting events such as tennis and basketball. The modularity of the spaces allows to welcome up to 10’000 spectators while offering pleasant premises.

The main innovation of the Arena’s heating-ventilation concept consists of distributing air through circular grilles integrated into the hollow profile of the concrete bleachers, fed by concrete pillar-rocks. Thanks to this fresh air supply from the stands, the 10’000 spectators and artists benefit from a comfortable atmosphere at all times. In order to reduce the volume of air to be treated and to realize an economic and energetically advantageous installation, a flexible system, perfectly adapting to the use of the hall was chosen.

This heating-ventilation concept can be summarized in four points:

  • Heating and ventilation: total control. The energy for the heating comes from a high temperature network (Remote heating by the incineration of household waste). Everything is based on the concept of blowing in the floor and the steps. This arrangement creates a layer of treated air in the occupied area that is close to ideal ambient conditions. The occupied volume is therefore perfectly controlled, and the spectators always enjoy a comfortable atmosphere and clean air.

  • Ventilation: heat recovery. The very important heat released by the people and the projectors is captured at the ceiling of the room and evacuated directly outside. In winter, part of this warm air is recycled, which results in great energy savings.

  • Natural cooling: There is no artificial cooling system. Outside air is blown into the bleachers or the central area, directly near the heat sources (people). This fresh air – generally colder than the ambient air – contributes to a natural, sufficient and free cooling. 
  • Versatile control system: In addition to the usual functions, this digital control system can be used to program 7 different air supply variants per zone of occupation, depending on the type of event: sports, conferences, shows…
