The holiday season is here! To celebrate its 25th anniversary, the Passive House Institute, together with IG Passivhaus Deutschland and the International Passive House Association, created an advent calendar to let you discover interesting facts and pictures about the Institute and its contribution to climate protection in the building sector. From December 1 until December 25, we will open a new door each day and unveil interesting facts and photos of the past years. Keep an eye on iPHA’s social media channels and don’t miss the content, offers and the calendar gifts!
