In the last decade, the awareness of climate sensitive and sustainable urban development is increased in Turkey. However, there are very few strategies managing this process at a stable, flexible and local scale. A climate-sensitive urban planning approach is the main strategy in this process requiring the effective integration of climate information into the design process especially for cold climate conditions as for all other climate zones. Since, the harsh winter conditions of cold climate cities create very challenging conditions in terms of outdoor design and outdoor comfort. It also directly affects the quality of life. These challenging conditions make cold climate-sensitive urban design principles and other application tools essential for winter cities. By this way, it is possible to positively change the effects of weather on the quality of life. In the light of this information, the effects of urban planning practices on microclimate of Erzurum as one of the coldest climate cities in Turkey are explained within the scope of this study. Accordingly, the analyses are conducted on four selected settlement patterns in the city within 2018-2019. The meteorological data of these settlements was obtained from the record taken from approximately 2 meters high from ground. Then, 32 climate simulations were made for these four different study areas. Additionally, thermal comfort level of the city was also evaluated at micro-scale, through these case areas. For the simulations and evaluations of thermal comfort, ENVI-met micro climatic model was used. Changes on air and surface temperatures during the winter period were investigated within the variations of design parameters. The findings show that the city is under extreme cold stress, especially in winter. It has been confirmed that urban design projects can increase outdoor comfort up to 2 degrees C in winter. The design principles used in the projects are based on the principle of location-specific climate-sensitive urban design principles produced within the results of simulations and theoretical knowledge obtained from literature. The results of this study will contribute to the knowledge of local governments and designers. It enables them to predict the impacts of simulated design parameters in similar districts.
