Recovery and reuse of structural products from end-of-life buildings
YesBuildings and construction have been identified as having the greatest potential for circular economy value creation. One source of value creation is to recover and reuse building products from end-of-service-life buildings, rather than destructive demolition and downcycling. While there is a trade in non-structural and heritage product recovery and reuse, the largest volume, mass and value of most buildings comprise structural elements – concrete, brick and masonry, and steel – which present many challenges. A comprehensive literature review confirms limited attention to innovation and advanced techniques to address these challenges and therefore the potential reuse of the stocks of accumulated building products globally and associated environmental benefits. Potential techniques being tested in an Engineering and Physical Sciences Research Council circular economy research programme are referenced as a key building block towards circular economy building system redesign.Engineering and Physical Sciences Research Council - research project Rebuild (EPSRC EP/P008917/1
Multi-objective design for space layout topology
A novel method to produce space layout topologies for architectural design is described. From the uniformly distributed design solutions in the solution space the corresponding design requirements are computed according to a given norm and metric function. The system is based on graph representation of the layout so that the desired relations between the pairs of nodes are considered to be independent variables of appropriate series of multivariable functions mapping the requirements into the solution space. The system so established is used as a knowledge-base for robust layout design where knowledge base having been established, the layout design requirements are introduced to the system as design constraints and the output is identified in the multidimensional solution space by means of interpolation. Since the smoothness of the interpolation is guaranteed, robust design layout, in the form of node locations, is obtained
A Fuzzy-Neural Tree Knowledge Model for the Assessment of Building’s Transformation
One building is more flexible in terms of use than the other and to determine how much a building ‘X’ is more flexible than a building ‘Y’ is a rather complex task. This research focuses on houses for the elderly in terms of future use, since the requirements have changed and many of the existing buildings do not meet new requirements. To asses a transformation of a building one needs to take many aspects into account such as: spatial transformation, technical transformation and their various sub-aspects. There are also different future use scenarios, defined by Netherlands Board for Healthcare Institutions, and one scenario is more suitable for a building than another. Firstly, in order to deal with this complex topic there is a need for a systematic approach where all relevant aspects determining a transformation value of a building will be defined. Thereafter, fuzzy-neural tree structure is used as a suitable method for knowledge representation and knowledge modeling.Architecture and The Built Environmen
Development of a decision support model for determining building life-cycle strategies in the Netherlands
Over recent years, it has become increasingly apparent that there is a growing need for so-called green buildings with a lower environmental impact over the whole building life-cycle. The construction industry demands strategies that support a drastic change of the way we develop, construct and maintain buildings. However, new building concepts represent too much of an evolution of traditional building systems, which does not necessarily lead to the intended shift towards green transformable buildings. The research aims to acquire knowledge about the impact of specific design characteristics on the complete building lifecycle, develop possible scenarios to create green transformable buildings, determine how the various strategies relate to the building lifecycle and to create knowledge about how to measure the effectiveness of the chosen strategies. The expected result of this research is a decision support model for building concepts. The model should lead towards a better understanding of innovative green solutions for buildings and therefore provide a better opportunity to create innovative new building concepts. This paper describes the research design, which will address the goals
