Summary

The results of the research project "Applying passive technologies in social housing" will be converted and checked in the context of the first Viennese social passive housing, Utendorfgasse 7.

Based on the planned building project in the Utendorfgasse the research project "Applying passive technologies in social housing" examined various questions which are highly relevant for the indroduction of the passive house standard in the social housing construction. Basis of the project were the published results of already established passive houses, in particular from the CEPHEUS project.

The following points were identified as substantial planning objectives:

  • High cost-efficiency
    Extra costs for passive house construction <= 75,- Euro/m² effective living area
    Construction costs <= 1.055,- Euro/m² effective living area
  • Low energy consumption - passive house standard
    Heating energy demand <= 15 kWh/m²annual
    Heating load <= 10 W/m²
    Air tightness n50 <= 0,6/h
    Primary energy demand <= 120 kWh/(m²annual)
  • High use comfort
    Controlled ventilation, acoustics, hygienic, user acceptance

Innovation

The central innovation of the project is the adherence to the international passive house standard and simultaneous extremely low construction costs. This innovation was possible by co-operation of seven offices in an integrated design process. The employment of dynamic simulation methods permitted the integrated judgement of the qualification of the single concepts (e.g. for ventilation, heating, building construction) taking into account different conditions such as house occupancy, user behavior, climate or loss of the power supply.

Wien14Utendorfgasse - First Viennese social passive housing

The results of the project will be converted and checked in the context of the first Viennese social passive housing, Utendorfgasse 7.

The total effective living area including loggias amounts to about 2.778 m². Each of the 39 units will have an average size of 73 m².

The property Utendorfgasse 7 in Vienna 14., has an area of 2.608 m2.

On the west side the property is attached to a closed log construction. The concept plans three structures, from which two are attached to the existing fire walls of the neighbouring houses.

The structures have a length of approximately 19 m and a depth of 15 m. The build-up area amounts to about 846 m². Each structure has a ground floor, 3 upper floors and an attic.

Each unit has southlateral windows and loggias or balconies (in the attic they have terraces). The access to the structures takes place via northlateral staircases. Thereby most units are exposed from two sides and can be cross ventilated. The constructional concept plans a building of disks (bearing cross walls). Thereby a large use flexibility is given with high economy.

Promotion of the demonstration project Wien14Utendorfgasse

The realization of the research results in the planned building project Wien14 Utendorfgasse adds substantially to the spreading and illustration of the results. In particular the magnitude of the project will draw attention on itself. Well visited by over 300 specialists and many property developers the workshop of the closure of the research project involved a broad media reporting.

Goals and results of the demonstration project Wien14Utendorfgasse

The goal of the project is the realization, further development and practice inspection of the six in the research project treated ranges used in the social housing:

  • Building concept
  • Civil engineering
  • Building services
  • Thermal and acoustic qualities
  • Cost analysis
  • User acceptance
  • User introduction

After closure of the demonstration project the following results divided into categories will serve as example for a multiplicity of passive house projects in the social housing:

  • Costs
    Windows, Fire protection flaps, Construction costs, Extra costs
  • Civil engineering
    Semicentralized: ventilation system; central: heat recovery, air filtering, supporting fans; decentralized for each unit: reheating battery and speed adjusted, in all operating conditions equalized, fans with 4-step regulation by inhabitants
  • Building
    Attachment of the thermal insulation, support of the building etc.
  • Qualities
    Thermal and acoustic quality, hygienic, Occupants info
