Real time data associated with the Building Information Model plays a critical role in the interpretation of the built environment, which is particularly relevant as an increasing number of education ...facilities and institutions promote sustainable engineering practices and monitoring data available to the public. However, it is challenging for non-technical audiences to fully comprehend or use information concealed in scientific data related to the performance of structures and materials. It is especially difficult for them to connect these concepts to physical contexts and phenomena. In this paper, we present how cross-reality paradigms in Architecture, Engineering, and Construction, coupled with multimodal representation techniques, enhance data literacy in both professionals and laypeople alike. In particular, we present the design of a learning environment where cutting-edge holographic interfaces and display technologies are combined with sonified and visual data to create a more immersive environment for data analysis and exploration, empowering users with situated data awareness and new ways of understanding real-time data.

The superior properties and the natural beauty of wood make it a desired material for various applications including construction, interior/exterior design or other uses. Unfortunately, wood as any ...other material is a subject of deterioration due to several factors, including among others; weathering, oxidation, biodegradation, wear or decay. It is important therefore to assure the performance of wood products during their functional service life. On the other hand, not just the functional performance is an issue, but it is extremely important to consider also aesthetical service life. The goal of this work was to study how the progress of surface changes affects customer perception of the wood. The effect of gender, age, education and nationality has been included in the research. A dedicated software tool has been developed within the frame of SWORFISH project and in collaboration with COST Action FP1006 "Bringing new functions to wood through surface modification". The set of 256 respondents representing different social groups has been requested to choose between images of wooden surfaces exposed to natural weathering and displayed on the computer desktop. The choice was related to the personal "end of aesthetical service life" and based only on aesthetical impression of the respondent. The same test has been repeated providing additional information defining the time of samples exposition to weathering. It was possible, after analysis of responses, to define the time when the wood surface is not anymore acceptable and requires maintenance. The statistical evaluation high-lighted difference between respondent groups but also change of tolerance for surface imperfection after realizing the efforts related to frequent repairs.

This paper presents a non-invasive technique that can extract an accurate geometrical description of growth layer surfaces in wood. The method has been validated for sawn spruce elements (
Picea ...Abies Karst.). The aim is to implement a procedure to model domain geometry in the numerical analysis of wooden elements, taking into account the intrinsic variability of the material. The approach presented by the authors avoids internal imaging and achieves a digital 3D model of growth layers, using, as input data, images of the ring pattern, which represents the growth surface boundary curves, visible on all the cut faces of the wooden element.
► Morphological macro-scale FEM models account for wood anisotropy and heterogeneity ► Wood growth layers are modeled from the images of the ring texture ► Detection of ring curves is done using mathematical morphology ► Ring curves are modeled as Non rational non periodic cubic B-spline ► Growth surfaces are modeled as filled surfaces from their boundaries curves

Volume is indexed by Thomson Reuters CPCI-S (WoS).The book covers a broad range of topics regarding the assessment and conservation of timber structures, with papers subdivided into ten themes: ...Assessment and conservation; Timber grading; Assessment by non-destructive methods and survey techniques; Assessment by testing and modeling; Reinforcement and treatment of timber elements; Strengthening of connections; Upgrading of timber structures; Monitoring; Learning from case studies; Codes and guidelines. The book will be of valuable use and precious help for consultants, specialists, practitioners as well as for researchers and scholars for what concerns assessment, conservation, repair and monitoring of timber structures and wood artifacts.The conference is held in light of economic, environmental, and safety reasons for assessing the structural health of wooden structures and extending their service life if possible. The 138 papers cover assessment and conservation, timber grading, assessment by non-destructive methods and survey techniques, testing and modeling, reinforcing and treating timber elements, strengthening connections, upgrading timber structures, monitoring, learning from case studies, and codes and guidelines. Among the topics are database research and development for visualizing invisible parts of wooden houses in Japan, a microwave reflectometric tool for the non-destructive assessment of decay in historic buildings, assessing damage and estimating residual service life of cracked timber beams, some Portuguese case studies of solutions for rehabilitating wooden structures, the influence of faulty 19th-century technical solutions on a work of 18th-century rafter framing as exemplified by a church in Nowy Kosciol in Poland, and classification criteria for the seismic vulnerability of timber roof structures.
In case of exceptional or accidental destructive events (e.g., earthquakes, floods, fire), the advisability of completely reconstructing a vanished artifact may be questionable. Among the possible ...approaches for reconstruction, the so-called philological method allows the complete reading of the whole building. Analogous to the study of literary texts, this method is based on the analysis of the "architectural language" of a building that is its form and its technical characteristics as well as its structural behavior. This case study concerns reconstruction of the timber roof of the Church of the Pieve in Cavalese (Italy), destroyed during a fire on March 29, 2003, for which the philological approach has been chosen. The design process consisted of two important phases: first the determination of the precise form of the original roof, by considering different kinds of evidence, then the introduction of necessary modifications, to meet the present-day structural standards. Such design choice, far from being a simplistic solution, involved the participation of different experts and a thorough multidisciplinary investigation.
