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