July 17, 2020 The theory of adaptive thermal comfort suggests that human comfort depends on historical and relevant outdoor conditions, as well as on an individual's ability to manage their environment.event to control. This suggests that humans have adapted to a wider range of thermal conditions. This can have a huge impact on the comfort of buildings and therefore on energy consumption.
Thermal comfort Thermal comfort is achieved when building occupants feel that the temperature, humidity, air movement and thermal radiation in their environment are ideal. Important research shows that indoor thermal conditions, as well as indoor environmental quality (IEQ), can have a significant impact on productivity and learning.
