Architectural Design of Big Lecture Hall in Relation to Air Conditioning System

Abstract

The paper is focused on architectural design of big lecture hall while considering the requirements of air conditioning system. Correct architectural design and design of air conditioning system is immensely important for students in the interiors of a university. Fulfilling CO2 values is inevitable not only from physiological point of view but also for achieving the desirable students' performance. Good architectural design must enable to apply the optimal air conditioning system, which ensures acceptable CO2 concentration. The high CO2 concentration is related to incorrect and insufficient ventilation in the big lecture hall and causes students to feel distracted and tired. Experimental measurements were carried out in the winter season in the big hall to evaluate the CO2 concentration. The device Testo 480 was used for the measurements. Obtained values of CO2 concentration are presented in the charts. Architectural design and mechanical ventilation system of the big lecture hall were evaluated based on the parameters of CO2 concentration. The paper concludes on how to create a harmony between architectural design and design of air conditioning system in the lecture hall.
