The performance of a passive cooling system was evaluated as part of design works for theproject of an auditorium. The passive cooling system incorporates an array of buried pipes together with a solar chimney. The natural ventilation is enhanced with the help of the solar chimney and fresh air is cooled by circulation within the buried pipes. The application of this system to the acclimatization of an auditorium was evaluated. A model was developed on this purpose, which allows foreseeing the temperature and relative humidity of the air in the auditorium. The performance of the passive cooling system was evaluated based on the number of cooling degree hours.
