Abstract

Using a newly refurbished Belgrade theatres, Belgrade Drama Theatre and Terazije Theatre, this study investigates weather two different mechanical ventilation systems are able to provide adequate thermal comfort and air quality and which one of them performs more satisfactory. In order to achieve the given objectives the four faze work was carried out. The first was the analysis of different ventilation strategies implemented in the theatres using the 'as installed' engineering drawings. Next step was the continuous monitoring of the following parameters such as: carbon dioxide levels (indoor and outdoor), air temperature, relative humidity, air velocity, and heat flux through the walls. Third was a detailed occupant survey. Finally, a detailed three dimensional CFD modeling of one of the theatres (Terazije Theatre) was carried out. It was find out that the measured air temperatures, air velocities , relative humidity and carbon dioxide concentration (C02) ware within the limits of thermal comfort standards, although temperature and C02 concentration were located at the extreme of the limits. Furthermore, the predicted results of Terazije Theatre showed good distribution of airflow characteristics and temperature gradients. Moreover, these were in agreement with the empirical measurements. In addition, recommendations were made to improve the thermal comfort, air quality and reduce the build-up of C02 concentration in the investigated theatres.
