A Case study on natural ventilation characteristics of the Diyarbakir Surici (Old City) Municipality Building in Turkey

Field measurements of the natural ventilation of the Diyarbakir Old City Municipality Building located in Southeastern Region of Turkey were conducted throughout a year. Ventilation need is determined from adequate and fresh air requirements to the working area for better working conditions. The objective of the study was to clarify environmental conditions that modify the health of the occupants and their sensations of comfort. In particular, natural ventilation quantity based on CO2 and O2 concentrations and open office planning are considered within this paper. The total airflow requirement and natural airflow rate were determined. The building should be ventilated hourly in order to provide necessary comfort conditions in case of all openings are closed. Finally, necessary recommendations on better working environment were made.
