SETAC 13th LCA Case Study Symposium edition:13 location:Stuttgart, Germany date:7-8 December 2006
Most important design decisions are taken during the first design phase. To reduce the environmental impact (EI) of buildings, a tool is needed for this phase. The element method for cost control allows making cost estimations during this phase and makes a gradual elaboration possible later on in the design process. An analogous method should be developed for EI calculations. The proposed methodology integrates EI and financial cost estimations from the early design phase. Moreover not only the initial cost and EI are taken into account, but the whole life cycle of the building is incorporated based on the combination of Life Cycle Assessment and Life Cycle Costing. Information about the EI of building materials is needed to carry out the LCA: EPDs are in that sense an important source of information. Both the additional financial and environmental return should be evaluated for additional investments. Choices will have to be made in case the financial returns are not in line with the environmental returns.
