Özet

Nowadays, shopping malls are commonly preferred by individuals for shopping needs as well as social needs. If these spaces where energy consumption and population intensity are changing hourly are designed compliant with comfort conditions, these spaces can be often preferred by people. Within comfort conditions, the importance of efficient use of energy should also be emphasized. It is necessary to make designs that can solve the problems such as increase in consumption of energy resources, increase in CO2 emission, environmental pollution, global warming, and ecosystem deterioration. Approximately 30% of the energy consumption in Turkey is originated from buildings, 65% corresponds to heating-cooling, ventilation, and hot water systems [1]. This ratio will most likely increase due to population increase and use of technology. Two shopping malls with different heating-cooling and ventilation systems have been selected, where one of the shopping mall has the BREEAM certificate which is one of green building rating systems, in Istanbul. The climate of Istanbul is classified as a temperate humid climate. The aim of this study is to measure and evaluate indoor environment conditions of these selected shopping malls in terms of thermal comfort. The measurements were made by considering the thermal comfort parameters such as air temperature, relative humidity, air velocity, and average radiative temperature. The measurements were made at the clothing department in the shopping mall and at the circulation areas of the storey where the store is located. Testo 480 thermal comfort meter is used as a measurement device. The obtained data were evaluated using Fanger's user satisfaction model of PMV-PPD graphical index and ISO 7730 standard, and the suggestions were presented as findings.
