The history of passive houses


1 passive houses are not only suitable for residential buildings, but also for office buildings, schools, kindergartens, supermarkets, etc.

The concept of passive houses first came from a discussion in May 1988 by professor Bo Adamson of lund university in Sweden and Wolfgang Feist from the Passivhaus Institut in Germany. The concept of passive houses was gradually established through a series of studies and funding from the government of the German state of Hesse.

The first passive houses were built in darmstadt, Germany, in 1990. In 1996, the Passivhaus-Institut was established in darmstadt to promote and standardize the standards of passive houses. Since then, more and more passive houses have been completed.

2, in the 1870 s, architects and scientists first began studying the zero energy consumption of building, reduce the energy consumption to zero is very harsh, although from the Angle of theory, it is feasible, but because of high cost and complicated process, so far is only stay in scientific research and project level.

Low energy consumption building (consumption of heating energy < 70 kWh/m² A) because of its superior performance ratio, it was soon popularized.

As the demand for energy saving is more urgent, the passive house has developed.

If you combine passive energy-saving house more solar power generation equipment, then also implements the zero energy consumption of building, because nobody is willing to live in a house without fridge and the TV.

3. As of 2010, there were more than 13,000 passive energy saving houses in Germany alone (37,000 worldwide in 2012), with single-family houses, apartments, schools, office buildings, swimming pools and so on. In particular, multi-storey buildings, such as the "Lodenareal" project, which can accommodate 354 households in Innsbruck, are the largest passive buildings in the world.

The basic principle of passive houses is energy efficiency. Outstanding thermal insulation wall, innovative door and window technology, efficient building ventilation, electrical energy saving are the basis for energy efficiency.
