Innovation in construction sector

Construction sector in Austria:

• important economic factor with long history and tradition;

• complex system industry: interlinked cooperation activities;

• construction product = complex product system; (Winch 1998, Nord 2011)

• currently undergoing various changes and challenges.

Timber construction:

• most firms are SMEs, family owned;

• new market opportunities (energy efficiency, climate effects, etc.);

• high innovation activity and strong development in Austria.

Trends in wood construction in Austria

Current upcoming trends:

• Lamited/cross-laminated timber panels

• Hybrid construction systems (with building core in fortified concrete)

and hybrid elements (concrete/wood slabs)

• Renovations, adaptations and extensions of existing buildings

• Multi-family/multi-storey buildings

Ongoing but well-established trends:

• Prefabricated elements

• Industrial/commercial buildings

• Community purpose buildings

• Single homes in traditional and in modern design

• Low-energy or passive house standard

Development of wood construction in

Austria

20 years of wood construction revival in Austria:

• started in province of Vorarlberg (west Austria) with a strong tradition

and strong networking of small carpenters, builders, architects, etc.

• diffused to whole of Austria.

Support:

• Provincial wood cluster organisations, university chairs, research

platforms, wood construction academy,

• proHolz Austria (public relations organisations with campaigns, advisory

services, magazine “zuschnitt”, wood construction awards, courses and

seminars, events, lobbying activities, etc.),

• Adapted building regulations (multi-storey, fire standards, etc.).

Specific activities:

• Wood construction awards of the provinces (usually in cooperation with

proHolz) e.g. http://www.proholz-noe.at/holzbaupreis-noe/

• zuschnitt magazine http://www.proholz.at/zuschnitt/ausgabe/67/

• list of projects (Austria and international)

http://www.proholz.at/architektur/kat/wohnbauten/

• Online information service http://www.infoholz.at/

• dataholz.com (HFA): Catalogue of reviewed timber building components for

thermal, acoustic, fire performance requirements and ecological drivers; detailed

technical descriptions of building materials for professionals

Rise of wood construction shares in

Austria within 10 years(Teischinger et al. 2011/proHolz)

• number of wood buildings in Austria rose between 1998 and 2008 from

25 to 39% (use area rose from 14 to 24%).

Rise of wood construction shares in

Austria within 10 years(Teischinger et al. 2011/proHolz)

• Residential buildings: share of 77% out of all wooden buildings;

similar share of wooden buildings out of all buildings;

most cases are renovations/annexes, only 2% are multi-family!

• Vienna: smaller share, smaller growth, smaller share in use area.

• Multi-family buildings: rise from 1 to 13% (4% in use area);

those are 98% attached appartments, only 2% multi-storey.

Highest potential in urban areas and multi-family/multi-storey buildings.

10 year trends in wood construction

Wood construction trends in Austria:

• Strong trend, but focused on smaller buildings.

• Large share (65%) of low energy houses (<50 kWh/m2a).

• Large share built with prefabricated elements.

• Strong research and innovation activity with public programmes,

university and industry.

• Innovative solutions emerge for multi-storey residential buildings.

• Hybrid solutions (hybrid slabs; concrete core and wooden structure).

Innovation analysis

Most important actors

• Architect and building promoter

Cooperation process

• Persistent & unrestricted interaction &

information exchange

Fostering factors

• Intensive cooperation

• Old tradition and craftsmanship,

experience and building culture

• Clustering of experts & regional

cooperation models

• Common fundamental idea

• Aim to open up new markets

Impeding factors

• Increased organizational effort

• Image, knowledge, prejudices

and Social Sciences

Overall conclusions

• Innovation factors for use of wood (in m-s. residential buildings):

• Role of actors: building promoters (municipalities and/or

residential building developers!), building companies,

architects, costumers (!)

• Role of institutional system: policies and regulations, city

planners (!), advisory systems and promotion, research, …
