The excessive emissions of greenhouse gases into the atmosphere has increased the global average temperature resulting to a phenomenon known as global warming. One of the major greenhouse gasses is CO2  and the various efforts are focused on curbing its emissions. Using the case of a multipurpose and residential building at the University of Santiago de Compostela in Northwestern Spain, this study assessed the environmental impact of installing smart lighting. This study quantifies the CO2  emission reduction, and economic cost associated to the technical improvement. Such action resulted to saving 126 MWh and a reduction of carbon emissions of 25 T annually, with a return period of six years.
