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
