Passivhaus Institut - Germany

Best Independent Energy Efficient Construction Institute - Europe

The Passive House Institute (PHI) is an independent research institute founded in 1996 by Dr Wolfgang Feist with a continuously growing interdisciplinary team of employees. PHI has played a crucial role in the development of the Passive House concept. Their first pilot project in 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.
