Passive house Kindergarten with an integrated therapeutical group

Applied passive house techniques with locally available materials for a public building using limited funds.

Short Description




The kindergarten workers have visited relevant realized buildings as well as a passive house. Findings from that have led to the briefing for design and pedagogical requirements which ended in an architectural competition. This competition which stressed ecological and passive-house aspects was won by "atelier hauptplatz drei", Kislinger Architekten und Partner.

The accompanying research program will put the local building on a significant regional level and will lead to the planned objective quality.

Research and Innovations

  • Particular challenge: the Kindergarten as a passive house.
  • The demand for a compact building qualifies the demand of the users for a single storey house.
  • Pedagogical requests in some respects conflict with optimized passive house concepts (for instance. variable room heights, or light levels).
  • Heat energy consumption will grossly depend on working hours - full occupation during workdays from 8 - 12, 12 - 16 with 20 % occupancy.
  • High levels of human waste heat during full occupancy lead to specific deviations in the calculated results.
  • Otherwise show particular rooms specific needs for fresh air supply or thermal comfort - the gym, store rooms or multi-purpose rooms. This will hamper air ventilation heating.
  • The use of passive house Kindergarten requires specific thermal comfort, indoor humidity, summer heat resistance or concentration levels of Carbon dioxide.

Specific aspects

  • The building is turned away 45° from south direction.
  • Low stratus during winter seasons.
  • Lowering the building up to 1m into adjacent terrain - suitable for handicapped.
  • After the analysis of numerous construction and technical variations the following components were recommended and commissioned, indicating advantages and disadvantages


The building will be located in a new housing estate of Ziersdorf in the south-western part of Weinviertel in Lower Austria.
