Abstract

This study aims to analyze thermal comfort and annual energy consumption in an intermittently used space. It is well known today that energy consumption in buildings is almost 30% of the total energy consumption in the world. Also, thermal comfort is another essential concern in buildings. Notably, in intermittently used spaces, energy consumption and thermal comfort are more problematic than in any other space. Although many studies investigate improving thermal comfort and decreasing energy consumption in the literature, any attempts to improve those two conditions in intermittently used spaces are still valuable.

Accordingly, in this study, the Davutpasa mosque located in Yildiz Technical University in Istanbul was chosen and modeled in detail. To enhance thermal comfort and decreasing energy consumption, natural convection and forced convection alternatives were also examined. Since mosque-style structures are visited intermittently, heating, cooling, and ventilation systems are started and stopped many times. This has a significant effect on both the energy consumption of the building and the thermal comfort perception of the visitors.

In this study, indoor air temperature, energy consumption, and occupant comfort of the existing condition in the mosque are compared with these two alternative cases by using Integrated Environmental Solutions <Virtual Environment> software package: 1) The stack effect condition that will occur by opening the windows close to the ceiling, 2) Adding exhaust fans on some of the ceiling level windows.

The analyses showed that both cases positively affect cooling season on building energy consumption, indoor air temperature, and occupant thermal comfort.
