Can thermal perception in a building be predicted by the perceived spatial openness of a building in a hot and humid climate?
The authors wanted to prove that there is a large correlation between the concepts spatial openness and comfort (visual, wind speed and thermal) perception in people’s minds in a hot and humid climate in summer in order to be able to use spatial configuration parameters such as openness, connectivity and depth as a design tool for a comfortable an energy efficient building in the early design stages. 513 local Chinese college architecture students in 2015 were questioned about the relationship between spatial openness and comfort perception. The main findings for a hot and humid climate are: a. spatial openness of a particular space significantly effects occupants’ visual perception, wind speed perception and thermal perception in a particular space (p < .05). b. There is a strong effect size between spatial openness and visual and wind perception (w = .50 and .54); the effect size of the thermal perception is weaker (w = .14). c. The comfort perception is strongly influenced by the time of day, therefore visual perception, wind perception and thermal perception can influence occupant movement between different spaces as is the advice of the adaptive thermal comfort.
