The growth of the cities influences the urban climate and may lead to localized increase of air temperature. Elevated air temperatures, especially during the
summer season, may have major implications for building energy demand, local air quality, and outdoor thermal comfort. The present study investigates the thermal behavior of a number of courtyards in the city of Vienna, Austria. Specifically, we
explored the diversity of microclimatic conditions in and around a number of geometrically different courtyards. We collected the weather data pertaining to the air temperature, humidity, wind speed and CO2, using both mobile and stationary weather stations. Results show the importance of the specific geometry of a
courtyard (height-to-width ratio, shading circumstances) in view of the courtyards' microclimate (day-night temperature differences, potential for night-time cooling
within the courtyard). When compared to the adjacent street, geometrically open courtyards show slightly more favorable thermal conditions, especially during morning and evening hours.
