Workpackages

The project is allocated to known and unknown fields of science and practice. Since centuries it is known, that only lifelong dry timber provides a in principle never ending durability of wood. But for the increased height of the buildings and the need of industrialisation, a new semi-probalistic approach is necessary to assess upcoming risks. A new semi-probabilistic risk façade model, RIFA, will be developed. It is the anchor point and end result of all the research work but it strongly relates to all other work packages.

TTF WorkPackages

1 Coordination (TUM)

In work package one the main taks and  goal is the fluent project development and coordination within Woodwisdom objectives.

2 Exposure and Stress (SINTEF)

In work package two the climate exposure on buildings and facades for the present and future climate will be characterized. Exposure levels for buildings with tall facades will be assessed and classified and relevant stress parameters will be defined. Data consolidation and assessment is included here. The expected outcome can be summarized as preparatory work for the exposure model and practical measurable functional exposure and stress indicators for architects and engineers designing tall timber facades.

3 Resistance and Damage Mechanisms (FCBA)

In work package three relevant façade typologies will be selected for characterization of its functional layers and performance (according to climate loads). Based on input from WP2 and previous research, experience and laboratory tests, a relevant classification and performance criteria (cladding material, insulation, air tightening, detailing) taking into account building requirements is developed, that states the overall performances for the façade. The outcome is basically the foundation of the vulnerability model.

4 Construction Methods (SP)

In work package four construction and design techniques will be reviewed in terms of their environmental, economic and building physics performance and requirements set for sustainable facade constructions. Evaluation of constructions and details that fulfill all other requirements on facades, such as strength, acoustics, fire, insulation and moisture. Identification of existing and innovative timber frame solutions for new building and retrofitting relied on the experience of the consortium and information from WP2, WP3 and industry.

5 Risk based model (NTNU)

In work package five, based on a consistent consideration of uncertainties associated with the estimation of the different model components, a risk-analysis framework is developed that is able to assess the cost-efficiency of façade design solutions. The framework is generic, i.e. the relevant variables are represented by indicators able to represent different façade systems and environments. This will lead in the end to probabilistic models for exposure and vulnerability, = risk facade model (RiFa) and semi-probabilistic design framework.

6 Dissemination (TUM)

The objective of work package six is to disseminate the results and outcomes of the project, to increase the knowledge of relevant industrial actors along the value chain of tall wooden facade development and construction and reach out to other relevant research initiatives in the field.
