Ecoefficiency in residential building -a prototype for optimizing consumption of resources
Abstract: This prototype was developed to determine key figures (classification numbers) for the resources(1) material, (2) energy and (3) (capital) expenditures for residential buildings. Distinction betweenconstruction and utilization phase should give the opportunity to plan long-term ecologically andeconomically sound products (i.e. buildings). Based on these key figures this prototype provides aranking of different modulations of a building. The ranking is done by simultaneous reference to thekey figures using Multi Criteria Decision Making (MCDM) methods.The prototype is an instrument for the decision-maker (planer, builder) to realize the impact onconsumption of material, energy and expenditures of different planning decisions (differentmodulations of a building). The linkage of ecological (material and energy) and economical (costs)rating constitutes an important innovation of the prototype.
Keywords: Eco-efficiency, sustainability, multiple criteria decision making, building constructions
