Acoustic and thermal comfort for theatres and multipurpose halls

Expert in air conditioning, ventilation and heating, ETT offers a solution that allows you to control temperature and humidity regardless of the hall occupancy rate, while maintaining optimal operational costs. Environmental noise reduction is a key element for high energy performance air conditioning units installed in multipurpose halls. ETT offers autonomous rooftop units specifically designed to meet these particular acoustic requirements.

As the manager or a multipurpose hall, the operator of a recreational hall, or a maintenance technician in charge of a theatre, you are certainly faced with the following issues:

  • Ensure thermal comfort in entertainment halls: The difficulty lies in the fact that the need for hygienic fresh air varies and the flow rate must be controlled according to the actual presence of occupiers (need to maintain a minimum temperature during vacancy periods). ETT technology provides air conditioning systems that meet the specific requirements for theatres and multipurpose halls.
  • Ensure acoustic and thermal comfort for the audience: To fully enjoy a show or concert, the audience needs to be in ideal conditions of thermal and acoustic comfort, while breathing clean air.
  • Reduce operating costs: air treatment represents 70 to 75 % of your energy bill. To address current challenges and help you reduce your energy bill, our approach focuses on improving thermal efficiency while reducing operating costs.
