Energy and environmental retrofitting of the university building of Orthopaedic and Traumatological Clinic within Sapienza Città Universitaria

摘要

To cope with climate change energy sustainability is considered the key target EU Countries set to achieve by 2020. Existing energy users such as building stock require huge efforts to be aligned to this goal. This is the case of the University of Rome “La Sapienza” campus since it was built even before first regulations on energy saving, i.e. Italian Law 10/91. Current energy classification assigns to them the energy efficiency class G, far from class A, the energy label to be achieved by 2020.\ud\udThe purpose of the study is the energy refurbishment of the Orthopaedic and Traumatological Clinic Institute building located within the “Sapienza” University campus. It is a historical building of great architectural value, designed by Arnaldo Foschini in the 1930s. The proposed interventions entail the total renewal of the building envelope, investigated by thermographic surveys, along with the installations of new heating and cooling systems. The architectural redevelopment is according to Italian Law 338 of 14 November 2000 for the construction of temporary accommodations and residences.\ud\udThe results obtained were analyzed to identify the best intervention strategy for a sustainable energy retrofitting of historical building, taking into account the preservation of its architectural values as well as making it fit for modern use.
