The Passivhaus standard was developed in Germany in the early 1990s and the first dwellings to be completed to the Passivhaus Standard were constructed in Darmstadt in 1991.
The Passive House Institute (PHI) is an independent research institute founded in Germany in 1996 and lead by Dr. Wolfgang Feist. PHI has continued to research, educate and promote the Passive House standard since its founding. On this side of the pond, the Passive House Institute US (PHIUS) was founded in 2007 and offers a stateside Passive House certification. The original International Passive House Association offers certification for Passive Houses worldwide – including the United States.
As is often the case – a bit has been lost in translation, from Passivhaus to Passive House. Passive House is neither just for houses nor are the buildings completely passive.
The “passive” in “passive house” refers to achieving overall energy savings of 60%-70% and 90% of space heating without applying expensive “active” technologies such as photovoltaics or solar thermal hot water systems to supply needed energy to the HVAC system. Energy losses are minimized and gains are maximized.
