Reduktion der sommerlichen Überhitzung durch ökologische Innenwände im Holzbau.

Reduction of summer overheating through ecological interior walls in timber construction Due to climate change, the importance of heat protection in summer is increasing. Lightweight timber construction is a particularly ecological construction method, although it is often criticised for not being climate‐adapted. This study investigated the influence of different interior walls on summer overheating and on the energy consumption of timber buildings. Five different interior walls were simulated in a single‐room model in WUFI Plus in combination with two different exterior walls in two scenarios. By using ecological, heat‐storing, hygroscopic interior walls, the operative temperature can be reduced by up to 1.48 °C depending on the orientation and shading. Temperature peaks in the summer months can be reduced in particular. If an indoor climate below 25 °C is aimed for, this means a max. reduction in cooling requirements of 26 %. The two interior walls made of rammed earth and solid timber construction with 3 cm clay plaster achieved the highest reduction. [ABSTRACT FROM AUTHOR]
