OPENING EVENT – room Tirol
Timber construction for the demanding real estate and housing industry
Moderation: Sandra Burlet, Lignum – Holzwirtschaft Schweiz, Zürich (SUI)
The general climate policy situation is causing a change in the values of investors in both the EU and Switzerland: with a view to the sales value of new projects and the value retention of existing portfolios, sustainability will increase from a soft factor to a hard criterion. Surveys of residential and office buildings in Switzerland show that timber construction is not only ecologically superior to solid construction, but can also keep up economically.

Organized by Aalto Universität Helsinki (FIN)
Current developments in connection technology
Moderation: Prof. Dr. Gerhard Fink, Aalto University, Helsinki (FIN)
Timber engineering has developed rapidly in recent decades. Wide-span halls and multi-storey residential and office buildings made of wood are now widespread. High-quality and reliable connections are the basic requirement for these developments. New and at the same time more demanding areas of application of the material wood require continuous further development in the field of connection technology as well as the integration of new knowledge into standardization. This year's prologue on connection technology deals with two topics: dismantling and assessment of connections as well as hybrid components, whereby the latter are also considered with regard to their dismantling and sustainability.

Eurocode 5 – What will change, what is new?
Moderation: Dr. Simon Aicher, Materialprüfungsanstalt Universität Stuttgart, Stuttgart (GER)
The aim of revising the design standards is to adapt the standards to the current state of the art. The target group are trained civil engineers with three years of professional experience. The standards are therefore not written for laypeople, but for experts. Following the discussions in the past and the comments of users, the European Standardization Institute (CEN) has defined the "ease of use" for the second generation of the Eurocodes as one of the core goals of the new series of standards to be implemented, i.e. practical suitability and improved applicability.

Bio-based wood adhesives and CO2-optimized wood-based materials
Moderation: Dr. Simon Aicher, Materialprüfungsanstalt Universität Stuttgart, Stuttgart (GER)
Against the background of the "European Green Deal" and the associated objective of doing business in the EU in a climate-neutral manner by 2050, companies are developing their own climate targets, with a focus on emissions. By decarbonizing processes, it should be possible to avoid burning fossil fuels in the future. However, higher demands are placed on load-bearing components. The agenda is something like the search for the Holy Grail: 100% emission-free adhesives for load-bearing wood-based materials based on renewable raw materials.

Wood structures
Wood structures are unique and different from other structures from an environmental point of view. As a natural and renewable resource, wood has qualities that are vital to our survival. If wood as a building material did not exist, we would have to invent it. Accordingly, all stakeholders in the construction industry are called upon to ensure that wood plays a greater role as a construction material than in the recent past.
Block A – room Innsbruck
Exposed engineering structures
Moderation: Prof. Dr. Philipp Dietsch, Karlsruher Institut für Technologie, Karlsruhe (GER)
Realizing extraordinary engineering structures made of wood has always had a special appeal for planners and builders. In addition to bridges and towers, timber construction has opened up new areas of application in recent years, such as wooden car parkades. But wooden bridges are also increasingly in demand. The revision of Eurocode 5-2 "Timber bridges" comes at the right time. Damage to existing structures also helps to learn lessons for the planning and execution of future wooden bridges.

Robust structures
Moderation: Prof. Michael Flach, Universität Innsbruck, Innsbruck (AUT)
Safety in relation to a possible structural failure should be carefully considered, especially in the case of arenas with large numbers of visitors. Thanks to biaxial load transfer, so-called redundant structures have the ability to dissipate loads through redistribution via different paths. As a result, they do not fail when the limit of one component is reached, but they use reserves of the entire system. The selected examples show interesting solutions on how the efficiency of supporting structures can be increased to make the load-bearing capacity safer.

Moderation: Prof. Andreas Müller, Berner Fachhochschule, Biel/Bienne (SUI)
Timber construction has established itself as a sustainable, reliable and economical construction method for multi-storey buildings well beyond the high-rise limit. In the case of large-volume projects in particular, the usual planning and production processes in timber construction benefit professional implementation. This minimizes the risks compared to conventional construction methods. Particular attention is paid to economic efficiency in the concepts - in addition to a high level of safety, robustness and reliability over the entire service life. This also creates space for continuous further developments and innovations.

The National Forest Inventory shows increasing wood stocks, especially hardwood. Damage caused by heat, drought and insects lead to an increase in the amount of damaged wood, especially in the case of spruce. In the future, due to climate change and planned forest adjustments, a decline in conifers and an increase in deciduous trees is expected. What about the usage options for hardwood? Which steps are necessary to promote the efficient material use of hardwood?

Epilog – room Innsbruck
From tradition into the future
The arrival of European and Asian timber construction cultures in the 21st centuryModeration: Prof. Wolfgang Winter, Technische Universität Wien (AUT)
A look at the media shows that urban, multi-storey hybrid timber construction has made a comeback in the 21st century after being almost completely replaced by steel and reinforced concrete in the 20th century. Highly acclaimed examples will be shown from the German-speaking area and Japan. These regions build on diverse and innovative timber building cultures, which also enriched building technology and architecture in the urban context up to the end of the 19th century. The epilogue is intended to discuss the extent to which centuries-old technical and cultural achievements in timber construction have been preserved, despite being suppressed in the 20th century, and can be reactivated and further developed in the 21st century. In addition to technical questions and cultural aspects, this also includes questions of resource availability and the feasibility of a renewed conversion of construction production.
