World's first Passive House in Darmstadt, Germany produces renewable energy.
The world’s first Passive House building has increased its already high energy efficiency level and now relies on renewable energy. About a year ago, a photovoltaic system was installed on the roof of a row house built in 1991 in Darmstadt. Since then, this pioneering Passive House project has been producing its own electricity, thus fulfilling the criteria of a Passive House Plus building. The official certificate was recently issued.
"Passive House buildings are perfectly equipped to utilise renewable energy. With their extremely low heating energy demand, it is even possible to derive as much energy from the sun on-site as is consumed in the house over a year", explains Dr. Wolfgang Feist. Together with his wife Witta Ebel he recently accepted the Passive House Plus certificate.
