Buildings for public entertainment represent a sector with wide-ranging and diverse characteristics. These buildings are often multifunctional in nature. System planning in such structures must take into account a number of constraints: the shape and volume of the premises, the specific noise and air quality requirements and the extreme variability of thermal loads, due above all to high crowding. The consistent supply of fresh air required in these facilities requests that particular attention be paid to energy-saving technologies, such as free cooling and thermodynamic recovery systems. Air handling units, and more specifically rooftop units in cinemas, are often the preferred solution.
