Türkiye’nin Farklı İklim Koşullarında Isıl Konfor Sıcaklıklarına Bağlı Olarak Konutların Enerji Performanslarının Değerlendirilmesi

Abstract

Thermal comfort depends not only personal parameters such as the human physiology, age and gender but also environmental parameters. The operation mode of heating, cooling and air conditioning systems and outdoor temperatures are important parameters for thermal comfort. As a result of experimental studies, Fanger formed an indicator called the “Predicted Mean Vote (PMV) “ and determined PMV=0 as the best value for comfort. In this study, first case building envelope properties were determined for four different cities representing four climatic regions of Turkey. Then thermal comfort temperatures were determined for each city and finally energy performance of the case buildings were evaluated based on these thermal comfort temperatures. The HVAC system was chosen as full mechanically controlled without allowing any personal intervention, analysed for both intermittent and continuous regimes. The study aims to exhibit user satisfaction and energy consumption change for each city when PMV=0. Statistical analysis of PMV values showed that although intermittent regime for Izmir gives lower energy consumption, continuous regime is better for Istanbul. For all cities, continuous regime consumes 4,5-6,2% more energy (kWh/m²) for heating, 9,1-23,2% for cooling comparing with intermittent regime.
