A Transdisciplinary Journey toward Thermal Comfort - Research Pathways
 
 
From www.buildingsandcities.org - 7 June 2023, 10:37
 

A significant missing component is understanding how occupants perceive and interact with a building. Numerous studies show that occupants play a decisive influence on energy consumption. The energy required for space conditioning is influenced to a large extent by the needs, expectations and practices of building occupants. Knowledge about the actual comfort needs and behavior of users is still insufficient. However, we are slowly moving from regarding occupants
