Term: PHI (Passivhaus Institut)

The Passive House Institute (PHI) is an independent research institute lead 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 12 kWh/(m²a), a consumption level confirmed through years of detailed monitoring.
