Performance oriented building assessment: a decision-support method based on an integrated approach

By the under construction European standard family of CEN TC 350, focused on a performance oriented building assessment, an integrated approach is suggested, announcing in the future “an overall assessment of integrated building performance”. Actually, even if the methodologies, the impact and the performance Indicators at the European level are developing following three different drivers (environmental, social and economic), in the real case studies of construction works it is not possible to ignore the interrelations between each action and the others as so as between the related effects. Similarly, to face the challenge of complexity, a multi-scale, multi-stage and multicriteria approach is needed, as well as the involvement of the stakeholders in the decisional process to give a new social answer and an impulse to the development of green economy and sustainable cities. The paper will report on the research focused on the development of an inductive, logical / operational decision-support method, aimed at optimizing the sustainable management of construction works based on the above conceptual model. The identification of a multi-criteria strategy, applied to the “Città Studi Sustainable Campus” in Milan, with respect to the energy, environmental, social and economic performances, is focused on key objectives / criteria / indicators.
