Project work at WISBA 2015 aims at conceptualizing a low-tech building that meets the requirements of a sustainable building in relevant future scenarios. As case study serves the concept of Building 2226 of architects Baumschlager Eberle as a particular innovative example of a low-tech building. Building 2226 is a multi-storey office building in Vorarlberg, Austria with, among others, the following features:

  • Ultra-low energy building;
  • Double layer monolithic brick walls;
  • No additional insulation (except roof and floor);
  • No distinct heating or air-condition.



The goal is to investigate how robust the design and low-tech concept is towards different future scenarios for climate change and change of use. At the end of WISBA students will need to deliver an integrated conceptual design and an integrated report summarising the implications of all three sustainability dimensions on the scenario.


Students are split in two project teams whereas each project team consists of three groups. One group has 4 international and interdisciplinary students which sums up to 12 students in each project team.

Project team A will design a low tech building with a particular focus on a climate change scenario. Project team B will focus on a multi usage conceptual design. The analysis will be made from an environmental, economic and comfort perspective.

An excursion to the building and theoretical input from architects involved in the construction of Building 2226 during the WISBA start conference in September at ETH Zurich introduces students to the concept of a low tech building. Based on data of Building 2226 students will analyse and interpret the implications of such a low tech building from a sustainability perspective by taking into account the following aspects:

Project team A:

  • Energy efficiency analysis;
  • Life cycle analysis;
  • Life cycle costs;
  • Life cycle design/comfort analysis.

Project team B:

  • Scenario analysis;
  • Life cycle analysis;
  • Life cycle costs;
  • Life cycle design/comfort analysis.


Based on the analytical outcome each project team is going to draft an integrated conceptual design and write an integrated end report.
