Problem Description
• Cinema closed without a renovating project defined;
• Cinema intervention in the air conditioning system;
• Cinema future decided on the beginning of this year;
• Alternatives presented by the cinema owner:
• Maintain the three rooms;
• Split the area in to a big room and a smaller one;
• Return to the original project (one single room).

Decision support
• Propose an innovating air conditioning system, which:
• Reduce exploring costs;
• Increase cinema appeal to the public;
• Serve as a marketing due to his innovation abilities:
• Excellent reaction time to occupancy changes;
• Low energy consumption;
• Thermo experience of the room;
