In this paper, the topic of thermal comfort for buildings with double skin façades and single skin façades is demonstrated and discussed. A long-term monitoring was performed in 280 office rooms distributed over 28 buildings in Germany. The survey methods were based on sensor measurements and data simultaneously gathered from questionnaire given to office users. The authors take into consideration the operative temperature, vertical gradient temperature, draught rate, radiation asymmetry, relative humidity and carbon dioxide concentration. The aim is to determine the individual sensory perception of the indoor environment and compare it to the actually measured indoor climate in buildings with double skin façades and single skin façades. In regards to the thermal comfort results, in general, it is shown that double skin façades buildings have slight advantages in relation to single skin façades buildings.
