For sustainable development, a reduction in energy demand is essential. This could be achieved through improving energy efficiency, effective energy conservation and management. The weather conditions of a given region are the most important consideration for the proper design of space AC (Air Conditioning) systems. In this study, the typical meteorological year and climatic database of Turkey for the energy analysis of buildings were generated by SQL (Structured Query Language) database programmimg language. The Finkelstein-Schafer statistical method was applied to analyze the hourly measured weather data of a 23-year period and select representative TMMs (Typical Meteorological Months). The selection criteria were based on 13 meteorological parameters. These parameters are the daily mean, maximum and minimum values and ranges of temperature, dew-point and wind velocity and the daily values of global solar radiation. According to results of TMY (Typical Meteorological Year), climatic database of Turkey including daily or hourly climate variables was created in SQL data tables.
