Air and light are important aspects at the Wildlands Adventure Zoo Emmen

Pleasant indoor climate with adjustable ventilation

On behalf of the Dierenpark Emmen, the building firm VolkerWessels is currently building a park that covers an area of 22 hectares: the new Wildlands Adventure Zoo Emmen. An important part of the park is the ‘Big Glasshouse‘, a large tropical glasshouse with a surface area of around 17,000 m2. VolkerWessels asked Brakel Atmos to design and install the building‘s air supply. The solution: controlled natural ventilation.

In the tropical glasshouse, visitors can view the animals and their colourful environments via various routes. The tropical environment also encompasses a restaurant and a theatre.

Natural ventilation

Brakel provided the air supply for the ‘Big Glasshouse‘ in the form of 143 natural ventilation façade vents. Louvered vents of the type Brakel® Eura-G have been used, in which 6-walled polycarbonate flaps are integrated. The flaps have the same specifications as the plastic façade into which the vents are installed.

Mesh grilles prevent escapes

The louvered vents are equipped with plastic mesh grilles on the inside. This prevents the smaller animals escaping from the glasshouse via the vents.

Aerodynamic flow-passage and control system

The total aerodynamic flow-passage of the façade vents, including mesh grilles, is 239 m². The louvres are operated via a 230V spindle motor that is proportionally driven on the basis of an intelligent GNV/ANV operating system. The operating system sets the open angle of the vents on the basis of the indoor and outdoor temperature, precipitation and wind (direction and speed).

Comfortable indoor climate

The set ventilation capacity is the determining factor in order to ensure a pleasant indoor climate, without draughts, at all times.

Fire safety

The façade vents which supply the air, are also part of the RWA (smoke and heat removal) system and open upon a signal from the fire alarm installation (BMI) in the event of a fire. The required capacity is also part of the total fire safety plan, as determined by DGMR.
