Passive House brochure

The Passive House standard was conceived when Professor Bo Adamson of Lund University, Sweden, and Dr. Wolfgang Feist of the Institute for Housing and the Environment, Germany, collaborated in 1988. The very first pilot project (the Kranichstein Passive House in Darmstadt, Germany in 1990) was Europe’s first inhabited multi-family home to achieve a recorded heating energy consumption of below 12kWh/(m2a) – just 10% that of the standard house at the time. This consumption level was confirmed via years of detailed monitoring.

The Passive House Institute (PHI) is an independent research organisation that was founded in 1996 to promote and control the standard and has played a crucial role in the development of the Passive House concept.

“The heat losses of the building are reduced so much that it hardly needs any heating at all. Passive heat sources like the sun, human occupants, household appliances and the heat from the extract air cover a large part of the heating demand. The remaining heat can be provided by the supply air if the maximum heating load is less that 10W per square metre of living space. If such supply-air heating suffices as the only heat source, we call the building a Passive House.”
