Description
Consuming about 60% of natural resources, construction industry recently has been under a continuous pressure to ensure an efficient consumption of natural resources. Recent decades have witnessed some valuable steps toward making the construction industry more sustainable. This includes the trials to change the linear life cycle model to cyclic one by the consideration of the 3Rs; recycling, reusing and reducing to help in closing the material loop. However, recent studies have showed that the reason for demolition is not really the end-of-life span of structures but actually the lack of adaptability, also, demolition and recycling demand huge energy. So that the possibility to dismantle/ disassemble/ demount an RC building in order to salvage its material for reuse has been under focus. This requires the design for deconstruction “DfD” to close the loop of materials similar to cradle-to-cradle model where “waste” is turned into “feed” in comparison with cradle-to-grave thinking. The structures should be designed as a prefabricated structures and elements should be joint in dry way. The current paper will review the concept of structure demountability in the context of the recent advances in building systems and the ongoing researches in the area. Some early real cases of demountable structures in Europe will be discussed and challenges including design requirements and future directions will be highlighted.
