TO BE CONTINUED 3 Wooden buildings and indoor climate in summer. Computer simulation of thermal comfort.

09/06/2023

Computer simulation of thermal comfort. 

- in terms of overheating in the transparent part, the importance of attenuation and phase shift is lost

- the dominant influence is in the transparent part of the building envelope

- research has shown that the impact of the storage core is overestimated

- on the contrary, night cooling is important
