Development of transparent, technical and economic models for medium and high volume residential buildings, with special focus on the non-profit sector. Topics such as generation living, teleworking as well as smart homes are developed in an integrated model, for dense structures as well as pavillons and townhouses. All models follow the three pillars of sustainability.

Short Description


Starting point / motivation

Limited profit developers face the following challenges in medium and large-scale housing construction, on the one hand to build cheap and at the same time provide solutions that meet the latest state of the art. These alone are already representing an almost insurmountable opposition.

Additionally, we face changes in society (reversal of the population pyramid, increased desire for self-determination, compatibility of work and family life as a desired form and economic necessity), as well as the demand for low-energy buildings.

The existing planning- and business models are not feasible respectively to comply with the provisions of the Austrian Limited Profit Housing Act (WGG). - in the field of MRG (tenant law) and WEG (condominium law) currently almost impossible.

Existing approaches usually focus only on one of the areas (for example, (assisted)senior residences, AAL (Ambient Assisted Living), Work & Family, low-energy office building, ...), but integrated holistic approaches are missing.

Contents and Objectives

Development of modular holistic technical and economic business models for project development within the possibilities of the WGG with following aspects:

  • Generation Living in the medium and large housing construction with AAL aspects (Ambient Assisted Living), innovative space concepts for children and seniors, day care concepts, including care facilities in the house
  • Life and work (office space with plug-and work-spaces) in the medium- and large housing construction, in consideration of mobility aspects such as:
    - access to public transport
    - E-Bike-Sharing
    - E-Car-Sharing
    - charging stations
    - Trolley solutions for purchases
    - central transport solutions, etc.
  • Smart Home - building envelopes are possible functional surfaces for energy generation and greening. Moreover, monitoring for optimizing operating costs with smart metering is provided. Modern IT infrastructure ensures that the two aforementioned aspects of AAL (Ambient Assisted Living) and the compatibility of family and work are accommodated by plug-and-play solutions and the possibility of simple upgrading to new technologies.


Interdisciplinarity of the team ensures an all-round view.

In the course of the project, expert interviews were conducted and evaluated, as well as peer group discussions in groups of different sizes. Existing models were collected and evaluated by qualitative content analysis.

The modular imaging and representation on a technical and economic level helps the systems to be easily adapted to new technologies or other changes in the environment.

The design comprises building patterns in different layers, which can be hidden or viewed to show on a modular basis. Furthermore, the advantages of an "industrial production" can be used, with individual adjustments (e.g.: mass customization).


The team worked on easily adaptable models, which are appointed for ÖGNI / DGNB certification:

  • Flat as such
  • Closed coverage type construction
  • Pavilion Construction (terraced houses)

In the course of the workshops the experience and expertise of experts from the real estate industry were bundled and incorporated in the result (designs, economic and financial analysis). The most exciting result of the scientific support and absolute highlight of the project was the integration of the project results into "system variant - residential properties" and "system variant Housing in use & Modernization" of the ÖGNI (Austrian Society for Sustainable Real Estate Economics).

Prospects / Suggestions for future research

A book will be published with the results of the project in the summer of 2018, in which the current building and housing law amendment 2016 and the new government program on housing will be incorporated. In addition, there will be further comments in the book on relevant trends in the real estate industry, as well as showcase projects for the implementation of WohnMODELLmit Zukunft. The new ÖGNI certification track, which was created alongside the research project, is also explained in this book.

A follow-up research project was submitted in spring 2016, and started in January 2017. The project deals with the technical provisions of a building to guarantee the well-being of its users: "Building soft skills" (FGG 856122) gathers 5 universities and 31 companies and research institutes in a research community. Reusability of rooms in a life-cycle as well as psychological aspects of living are some topics among others.

Since one of the project partners is a non-profit housing developer, the project results will be incorporated into their future projects, and "smart living" will be part of their procurement procedures.
