Abstract: Since most important design decisions are taken during the first design phase, an evaluation of the total environmental impact is necessary at that moment. A first step in that direction is taken by the Flemish government through the introduction of the Energy Performance Norm (EPN) from January 2006 on. The EPN evaluates the overall energy consumption of buildings during the use phase instead of looking at thermal insulation and compactness only. However the environmental impact is not only caused during the use phase of the building, moreover not only energy consumption, but also emissions, depletion of resources, land use, etc. contribute to the environmental impact.
A methodology is being developed to evaluate all these aspects during the first design phase. It is based on different existing methods: life cycle assessment, life cycle costing and the element method. Moreover the financial cost is incorporated in the evaluation since it is often an important decision parameter. The marginal effects of the environmental and financial costs are used as criteria for ranking possible choices. The methodology will be described and illustrated by a case study.
