Mid-year event



From 8 – 10 June 2018, the mid-year International Passive House Open Days, organised by iPHA and its international Affiliates, once again took place. The mid-year event allows participants to experience Passive House buildings during the summer (or winter) months as opposed to the main event in November. 


This year, over 100 Passive House projects opened their doors to the public, with owners and architects sharing their experiences and showing what Passive House is all about.
