Sustainable campus: Renovation of lighting fixtures for the reduction of CO2 emissions

The work deals with the reduction of CO₂ emissions in school rooms of Politecnico di Milano, through the upgrading of lighting fixtures, in the context of the Città Studi Campus Sostenibile project. The aim is to provide an extensible intervention strategy to all the buildings of Politecnico di Milano and, more generally, to the School Construction, starting from the analysis of a limited number of buildings. Starting from the energy analysis of the current status in order to formulate the most appropriate methodologies for each classroom, three classifications have been suggested: age or generation, illuminance and energy. Two methods have been developed, with the purpose to design new efficient lighting systems. These strategies have led to a large reduction of consumption and, thus, to a reduction of CO₂ emissions improving also the lighting comfort.
