A multilevel method to optimize the sustainable construction works

The new European standard family of CEN TC 350, still in progress, is supposed to be as guidelines of the performance oriented building assessment. The perspective suggested by the standard family is multidisciplinary. The future developments are expected to go more and more into the direction of the integration of the three major components in the life cycle: environmental, social, economic. This is a sufficient ground to start managing any case of construction works as an interdisciplinary project, thinking and planning any action as the integration of a certain number of actions, with a multiscale and multilevel approach. The paper reports on the research focused on the development of inductive, logical / operational guidelines, aimed at optimizing the sustainable management of construction works. The identification of a multiscale and multilevel strategy aiming at supporting the decision-making process, applied to the “Leonardo da Vinci Sustainable Campus” project in Milan, with respect to the energy, environmental, social and economic performances, is focused on key objectives / criteria / indicators. The holistic approach and the involvement of the stakeholders in the method, supported by multiple criteria decision making (MCDM) models and methods, aims at giving transparent and shared answer to the search of the best technical solutions and strategies in a large sustainable perspective.
