Abstract [en]

The implementation of computer design within the building industry has created new possibilities for creating digital tools for users such as architects. There is however a lack of easy to use, efficient digital tools to aid and explore design alternatives for architects when using products within the wood building industry. This paper demonstrates how a modular facade system in wood can be adapted for facade configurations in different contexts by using computational design. The goal is to develop a digital design tool that is easy to use and provides the architect with a high degree of freedom to create project-unique facades. The design tool is developed with computational design methods for flexible and adaptive design. In parallel, assessment is made that the design solutions can be manufactured smoothly and quickly via digitalization and industrial production. The result of this research shows that the façade system can be customized by using parametric programming methods, and thus enable architects to design facades for different contexts. The design tool was verified with the architect partners concerning usability and manufacturers concerning production.

Abstract [en]

There is a need for a shift towards circular economy in the building and construction sector. Design for deconstruction and reuse (DfDR) and design for adaptability (DfA) have been suggested as means to facilitate reuse of buildings and diminish waste and material consumption. A standard, ISO 20887:2020, has appeared to support the implementation of DfDR/A. One objective of this study is to demonstrate timber building design examples that can be considered consistent with the standard and designs that should be avoided. Another objective is to examine if there are important aspects of DfDR/A for timber buildings that are insufficiently covered by ISO 20887:2020. The broader, long-term aim of the work is to remove thresholds to DfDR/A by providing support for designers and industry in applying the standard. The principles and strategies in ISO 20887:2020 are illustrated with practical examples from case studies, organised in a searchable database.

Abstract [en]

The objective is to demonstrate the co-operative design (co-design) and production development process of a new wooden façade system. Today, architects and designers are seldom involved in the development process when designing new products within the wood building industry. The architect and the actors in the wood value chain are far from understanding their respective standpoints in new product development, thus creating a gap. This gap between actors hinders innovation and can mean that valuable design knowledge and methods are not used that can promote innovation in the wood building industry. In this paper we demonstrate how the development process of the façade system is profoundly influenced and improved by incorporating knowledge of the design process. Product development is becoming more and more complex and therefore more knowledge intense. This was addressed by working in parallel with partners coming from different areas of expertise, resulting in a co-design process considering aesthetic and functional requirements as well as the industrial manufacturing processes, interactively, throughout the entire development process. Using co-design when designing an adaptable facade system has proven to enable assessment of complex requirements, resulting in a sustainable system that can ensure good quality on material, aesthetics, and functions.

Abstract [en]

There is a need for a shift towards circular economy in the construction sector and design philosophies as Design for Deconstruction and Reuse (DfDR) and Design for Adaptability (DfA) are being developed as means to design out waste and enhance resource efficiency. However, applying these philosophies is not yet common practice. The amount of DfDR/A timber buildings described in literature is limited. This study aims at increasing and spreading knowledge on DfDR/A for timber buildings. It has four goals: 1) To suggest methods to apply DfDR/A. 2) To suggest new design solutions. 3) To collect experiences on connections in relation to DfDR. 4) To suggest how guidelines for deconstruction and reuse can be formulated. The study presents three methods that all proved valuable in applying DfDR/A: one discussion-based method to improve an already existing timber building design, one indicator system to assess the DfDR/A potential of building designs, and one matrix to guide design decisions. We used the first method to conduct five case studies in four European countries. The studied designs were judged to be well or relatively well adapted for deconstruction and reuse already today. The fact that the studied buildings are all offsite manufactured and of modular composition benefits the deconstruction process, partly because construction and deconstruction are similar processes so that the knowledge and infrastructure that companies have can be directly transferred to enable deconstruction and reuse. Where large modules can be recovered, the time and energy needed for deconstruction as well as the risk for damage will be reduced. Disadvantages to deconstruction and reuse identified were typically linked to the complexity of building modules and that individual components are not independent. This was reflected as irreversible or hidden connections, inaccessible services, interconnected layers of the structural modules and many different component sizes. One of the case study buildings, designed with mass timber panels, excelled in the simplicity and reduction of number of steps required for maximum material recovery. New designs suggested included making fasteners more accessible to deconstruction, avoiding letting sensitive materials as plastic foils and particle boards pass continuously over joints between elements, and (for cases where standard units are not already used) standardizing elements. One case suggested using solid wood components instead of engineered wood products to achieve durability. The study showed that simple changes in design can lead to an augmented reuse potential. Some of the new design solutions generated will be taken into production by the participating manufacturers. Insights on connections included recognizing the fact that the use of reversible screwed connections is not sufficient to ensure deconstructability and that although nailed or glued connections severely complicate reuse of components, they might be accepted within elements in case reuse on element level is the target. Guidelines for deconstruction and reuse were developed in all case studies. Taken as a group of studies, there are advantageous additions proposed to earlier guidance documents. Despite being based on the same source, the different plans suggested varied substantially. There was a noteworthy difference between manufacturers’ in-house plans to those proposed by architects, engineers, or researchers, which speaks to the uncertainty regarding the appropriate structure and format.

Abstract [en]

This study reports on a deconstruction process followed on site, with the purpose of documenting experiences that can help us understand how to design timber buildings for future deconstruction and reuse. The deconstruction concerned three timber buildings built up by volumes (3D modules produced off-site). Modules were in good shape at the time of deconstruction except for some minor local moisture damages. They were all covered and transported to be reused elsewhere. Experiences made included that lack of information on the assumed deconstruction process delayed and complicated the work. A need for disassembly plans was highlighted, including things as order of dismantling, positions of lifting points, weight of modules and positions of screws and amount of screw used. Results indicate that simple, clearly visible joints and services, limit the potential problems and damages during deconstruction. The building should simply be designed to be taken down in the future, the amount of screw allowed should be clearly described and the number of attachments should be limited. Furthermore, the risk of burglary during deconstruction needs to be considered as this may cause damage and delay.

Abstract [en]

This report describes the design development to meet the project's established aesthetic and technical requirements of a façade system in wood within the project “The facade of the city Swift, Stylish, Smart”. The development of the design was performed in close collaboration with the project partners throughout the project. In this way, questions about the manufacturing process, assembly and maintenance have been continuously weighed in and provided inspiration and deepened knowledge for the design outcome. The goal of the project was to design a facade system of good architectural and technical quality made of heartwood of pine, well adapted to meet the requirements in an urban environment. We have set the limit for the facade system to a maximum of eight floors. Overall, the façade system must assure market competitiveness and provide a clear added value compared to competing façade materials in terms of design sketch ability and environmental aspects and thereby contribute to a bio-based economy. The result is a facade system designed for the high demands in the future building industry regarding recycling and environmental requirements on materials and components. It consists of façade cladding with mounting system, joints and connections to windows and corners made of sorted and defined raw wood material using a minimum of metal and glue assembled into a facade system. The system has been tested regarding fire according to SP Fire 105.

Abstract [en]

The building sector accounts for a large raw material consumption and waste production. One way of diminishing these would be to reuse buildings and building components to a higher degree. To facilitate that, buildings would need to be designed with that aspect in mind. Work Package 2 of the InFutUReWood project investigates new ways to design timber-based structures. This study investigates how new design concepts can be developed to make Villa Anneberg, a two-storey light timber house from the Swedish manufacturer Derome, adapted for deconstruction and reuse. The objectives are: • To identify the inherent strengths and weaknesses of the current design of Villa Anneberg regarding deconstruction, rebuilding and reuse. • To show how the design could be improved with respect to future deconstruction and reuse and to estimate the amount of wood that could be reused in the future with the current and the improved designs. • To suggest guidelines for deconstruction and reuse. • To test and develop a method for carrying out case studies, as the study is the first in a series of case studies treating different structural systems. The study is limited to the load bearing structure of the building. Focus is on reuse rather than recycling. Methods used involve interviews, structured meetings, analyses of drawings and documents, photo documentation and design work. A reuse scenario was assumed where the building will be deconstructed after a few decades into its separate parts. It will then be transported and reassembled to an identical building in the same geographical region. It was found that the current design of Villa Anneberg is relatively well prepared for this scenario already. The building is designed for efficient transport and assembly and the process is judged to be reversible to a high degree. Many connectors are screwed, and the building can be deconstructed with common and simple tools. Several weaknesses were also identified. Among these were joining techniques that are not reversible. Modified versions were developed for three joints. The new solutions were achieved with relatively small adjustments in design and within existing technology. One of the new connections was found so economically valuable to the manufacturer Derome, that it is likely to be taken into production soon. We estimated that the proportion of wood that is reusable would be higher for the modified Villa Anneberg than for the current. The proportion wood that is reusable in the load bearing structure with current design is estimated to 82,7 %. The proportion of wood that is reusable with the modified design is estimated to 86,4 %. These figures apply to the studied scenario. Guidelines for deconstruction and reuse were suggested. The case study method was found efficient and ready to be used in further case studies.
