Abstract

Current Situation:
The subsidized housing has undergone a price pressure resulting from increasing normative requirements (resulting in higher building costs), declining funds for subsidized housing and rising land prices. An increasing need for affordable housing and increasing desire for participation in housing projects, contradicts missing policies that support Smart Citizens in the shaping of their city.

Problem:
This requires appropriate planning tools to reliably implement cost-effective, ecological, sustainable value and common construction methods in subsidized housing.

Motivation for carrying out the exploratory:
Extension of the role of planners: The professional field of activity of planners is extended by communication and process design for self-builders at construction sites.

Goals:
Transfer of "cultural knowledge" from the DIY Communities into an 'urbanized' construction practice that fullfills all current normative and technical requirements of building and also applies for the strategy of resilience (= usage openness). Designing a set of DIY grade, multi-storey constructions and evaluating their quantification (cost, life-cycle assessment) is the core task of this research program. Components are broken down into individual hands-on steps and their installation processes will be defined.

Methodology
A sustainability assessment of the construction types is carried out using common assessment criteria (TQB, EconCalc and ÖGNI). The DoE method is used for weighting own evaluation criteria, which is suitable to simulate tasks that have many free parameters.

Innovation:
Synergetic consolidation of the following topics: Community driven DIY, Raumrohlinge (space blanks) and ecological building. Technical support and empowerment of civil society building cooperatives already in the early phases of the project. Extension of the role of planners: communication and process design for self-builders at construction sites. Paving the way for open planning methods (Open Design, Peer Production etc.)

Anticipated results:
A multi-criteria-catalogue for initiatives and planers enabeling individual projektdesign for appropriate constructions within the given socio-economic parameters.
