**3. Pedestrian level comfort in urban texture**

In recent years, the number of studies on pedestrian comfort levels around buildings has increased in urban textures where building densities have increased. Due to the necessity of analyzing the negative comfort conditions that may occur at the pedestrian level, pedestrian health, and safety conditions very well, the urban texture and buildings have started to be analyzed in detail. The wind is the most important microclimatic parameter that affects pedestrian level comfort around the building. Wind movement manifests itself in basically two ways at the pedestrian level: it can either be felt like a wind speed that affects the heat exchange between people and the environment, or it can be felt as a force from the sum of the pressure field on the human body [7]. Urban wind flow has many effects on pedestrian level comfort, including heat transfer via convection, penetration of rain, dilution of pollutants, noise, or dust removal. In this study, only the mechanical effects of wind on pedestrian comfort are discussed. Pedestrian thermal comfort threshold at pedestrian level

corresponds to wind speeds of about 4.50 m/s [8]. Pedestrian comfort conditions between buildings depend on several parameters. Among these parameters, biological factors such as wind speed, local climate, ambient temperature, precipitation amount, humidity, the activity level in public spaces, clothing, age, and psychological states of people come to the fore. A preliminary assessment of wind behavior at ground level and around buildings can prevent excessive wind speeds [9]. Pedestrian level outdoor microclimatic comfort between buildings can be achieved by applying the right design strategies of building groups together with open/semi-open and closed spaces within the urban texture. For this reason, in advance, meteorological analysis, evaluating the data according to the microclimate of the settlements, and planning the building form and settlement will increase the quality of life.
