Spaces dedicated to sports and leisure activities are usually multi-functional, hosting sporting events, concerts, shows, exhibitions and recreational activities. In addition, they also combine areas dedicated to the public with those dedicated to competitive sporting events. The coexistence of these various activities aims to make full and continuous use of these facilities, offsetting the high original investment in as short a period as possible. Consequently, the design of technological systems, especially those for air conditioning, must ensure maximum flexibility in terms of management and control. The large spaces and the high crowding index that distinguish these structures imply that air handling systems are the most common solutions. The high share of energy required for air renewal is a key consideration, as such heat recovery units and free cooling systems are strongly favoured.
