Darmstadt/Wuppertal, Germany. Passive House is celebrating its 30th birthday – and is more relevant than ever before. The 25th International Passive House Conference demonstrated how important it is to implement climate protection in buildings on a large scale. The Passive House Institute moderated the anniversary conference live in the Historic Town Hall of Wuppertal, for the participants it took place online. The research institute emphasised the key role that energy efficiency plays for climate–compatible building stock. The atmosphere became celebratory during the triple jubilee and the presentation of the Passive House Award 2021 to 14 awardees in total. Towards the end, the Passive House Institute announced that the 26th International Passive House Conference would take place in Spring 2023.
