The Passive House Institute (PHI) is an independent research institute founded 1996 by Dr Wolfgang Feist with a continuously growing interdisciplinary team of employees. PHI has played an especially crucial role in the development of the Passive House concept. The first pilot project (Kranichstein Passive House, Darmstadt, Germany, 1990) was Europe’s first inhabited multi-family house to achieve a documented heating energy consumption of below 10 kWh/(m²a), a consumption level confirmed through years of detailed monitoring. Since then, the Passive House Institute has assumed a leading position with regard to research on and development of construction concepts, building components, planning tools and quality assurance for especially energy efficient buildings.
