    Conservation of materials resources by buildings reuse and on site materials reuse strategies
    (Universidad de Sevilla. Escuela Técnica Superior de Arquitectura., 2015) Amoêda, R.; Mercader-Moyano, Pilar
    Rethinking buildings and construction activities is a fundamental step towards sustainable construction. Being one of the most materials consumers, changes to current practices in the construction industry are crucial in order to effectively reduce primary resources exploitation, as also to reduce the environmental impacts associated with it. End of life of buildings are opportunities to close the materials loop, by means of building renewal and recovery of components and materials. In this context, building reuse and on site materials reuse have shown to be the most preferable end of life scenarios when compared with off site reuse, recycling, energy recovery and landfill disposal. Moving from demolition to deconstruction is one of the changes that are supposed to happen. Another is to change the materials selection procedures in order to consider also reused materials as a valid option in architectural process. Therefore, surveys to assess reuse potential are needed prior to architectural design in order to look for reuse opportunities and reuse constrains both at the building level and materials level. Such opportunities and constrains comprise building adaptability, building conservation state, mechanical and aesthetic performance of materials, feasibility of components and materials recovery. However, existing buildings were not built to be deconstructed and materials recovery is a labor intensive task, facing obstacles as non reversible connections which usually destroy materials integrity. A case study for building reuse and on site materials reuse is here analised in order to illustrate the theoretical principles and goals that drive the reuse approach, highlighting the environmental benefits by keeping Embodied Energy and thus reducing the Global Warming Potential related to construction activities
