Acoustic ceilings can help to create an all-embracing silence
Silence. You immediately notice it when you enter the Créagora building which is occupied by health insurance fund, Christian Mutuality, in Champion near Namur. A pleasant, all-embracing silence.
And all this while our eardrums have just been plagued by the persistent noise from the nearby motorway. A few seconds in the interior of Créagora is suffice to make you aware of the extremely positive influence of the acoustic ceiling solutions from Rockfon, which have been applied in a well-considered way to promote the comfort of employees.
"As a client, we were confronted with two major challenges in this project: the sloping terrain and the motorway, the noise of which is amplified when it rains," says Didier Géronnez, project manager and building manager at Christian Mutuality.
The acoustic engineer at AVEA consulting worked out a terrain model by monitoring the sound level for fifteen days with the help of sound meters. The model showed that at certain moments the noise increased to 85 dB which is the maximum recommended exposure limit for human hearing!
The results were transferred to Atelier 4D and Atelier d'Architecture Ad'A architects, who co-designed the building. They designed it in a rigid north-south orientation to retain perspectives and to preserve the surrounding green environment as much as possible.
Sacred silence despite a busy working environment
Inside the building, conversations do not disturb others. In meeting rooms, you only notice the slight buzz of ventilation and you cannot hear the large training session being delivered in the adjoining meeting room separated by movable walls. "It is undoubtedly the excellent acoustic performance that ensures that these days we get more and more requests from companies that want to reserve our meeting rooms," said Didier Géronnez.
This is thanks to the 3,000 m² Rockfon Tropic acoustic ceiling tiles that can be found on all floors.
The call centres
In the two large office spaces reserved for call centres, the acoustic properties are enhanced by sound-absorbing furniture, which has been custom-developed based on the specifications of the acoustic engineer. In the first call centre, CM employees receive calls from elderly people and sometimes have to be able to speak loudly without disturbing their neighbour. These senior customers feel must not experience disturbing background noise on the call. In the second call centre, the operators receive approximately two thousand calls a day.
Despite these thousands of conversations, there is a consecrated silence in both spaces.
The philosophy translated into "vertical street" to create a wow effect
"The first discussions within the framework of the Créagora project were not about the building, but about the philosophy behind the project," recalls Didier Géronnez.
