* Because the provision of domestic hot water represents the greatest energy requirement of this house, an efficient domestic hot water system is of great importance. The heat distribution and circulation pipes have therefore been placed inside the thermal envelope and are well insulated.\\ | * Because the provision of domestic hot water represents the greatest energy requirement of this house, an efficient domestic hot water system is of great importance.

The Passive House in Kranichstein was finished in October 1991 and has been inhabited by four families since then. The interior finish materials were selected to create as little indoor air pollution as possible. The insulating materials are airtightly separated from the interior by continuous interior plaster or vapour retarders without any gaps – as appropriate from a building physics perspective. The good air quality was confirmed by a separate investigation within the context of a social science study, which objectified user acceptance [[examples: | The Passive House in Kranichstein was finished in October 1991 and has been inhabited by four families since then.

- | It is pleasing that many architects, planners, product developers and property developers have applied the Passive House concept. If we can continue together to accelerate its implementation and apply our experiences for the refurbishment of existing buildings as well, then we will be able to master the task of climate protection and contribute to a fairer distribution of energy globally, as well as increase value creation in regions and thus create additional employment opportunities – and most importantly – enabling people to live a comfortable and worthwhile life in prosperity, today and in the future. Sustainable growth is possible with the Passive House - as Mark Zimmermann outlined in detail at the 9th Passive House Conference in 2005 in Ludwigshafen ([[examples: | + | It is pleasing that many architects, planners, product developers and property developers have applied the Passive House concept |

- | Scientists, architects, engineers and other contributors from various disciplines played a part in making the Passive House in Darmstadt-Kranichstein a success. The author would like to express thanks to all those involved. The preparation of the experimental construction was based on the results of many forerunner projects and on findings from building physics, building engineering and systematic computer-assisted systems analysis.\\ | + | Scientists, architects, engineers and other contributors from various disciplines played a part in making the Passive House in Darmstadt-Kranichstein a success.
