In this study, the heating design temperatures (HDTs), the freezing degree-hours (FDHs) and the number of freezing hours (NFHs) were examined for the selected cities in Turkey. Eight cities were selected for the analyses, which represent the different climatic regions of Turkey. In the analyses, the typical meteorological year (TMY) data was used. According to the results, the yearly minimum and maximum FDHs were calculated as 27.2 and 13,842.5 for Adana and Sivas, respectively. The minimum and maximum NFHs were obtained as 25 and 2,355 for Adana and Sivas, respectively. Sivas had the highest FDH and NFH values for all the cases. Therefore, Sivas had the highest risk of freezing and icing. Additionally, there was not a significant risk of freezing and icing in Adana, Denizli, Istanbul and Trabzon. The HDTs were calculated with the most current data for Turkey.
