91 Implementing Material Efficiency Strategies in the Early Design Phase M. T. Nielsen and C. K. Haugvaldstad DTU Architectural Engineering, Technical University of Denmark ABSTRACT Optimisation of material efficiency represents a large potential in energy consumption reduction. This project studies which environmental benefits implementation of material efficiency strategies in a design proposal may result in. A renovation project in Stavanger represents the case where the strategy of direct re-use of materials is implemented in the design stage. The project thereby challenges the established mindset of building design which is designing a building and producing materials to fit the design. Our case relies on the existing materials to set the restrictions of the new building’s form and shape. Architecture is all about finding limitations and setting constraints for the design. In reality, only laws of physics and economy limits the possibilities for the architect. By striving for optimum material efficiency, a natural motivation occurs and a challenging aspect arises in the development of new design proposals. A LCA has been made to evaluate the environmental benefits and impacts resulting from a design strategy relying on the existing materials to set the restrictions. The LCA of our alternative design proposal is subsequently compared with more conventional design approaches relying on more or less complete replacement of the existing structures. This project intends to inspire a new approach to building renovation cases, and encourage building designers to realize the possibilities in the existing structures and materials and hence to minimize the demand for producing virgin materials. 406 BUILDINGS AND INFRASTRUCTURE POSTER IDEA BACHELOR FINAL ASSIGNMENT
