Energy Refurbishment of the General Physiology Institute at Sapienza University Campus

Abstract

The energy requalification of the existing building heritage is one of the pillars European Union energy policy. A large part of the building heritage was built without taking into consideration the problem of energy consumption. With the aim of energy efficiency and energy savings in electrical uses, there are wide and diversified possibilities for improvement, including interventions on the building envelope and on the systems, with the introduction, where possible, of renewable energy sources. In this context, the redevelopment of historic buildings constitutes an important challenge, which involves both historical-artistic aspects and technological aspects relating to the improvement of energy efficiency and comfort. A critical analysis of every possibility is essential to preserve the balance between efficiency and architecture. The purpose of the study is the energy retrofitting of the Institute of General Physiology located within the “Sapienza” University campus. The proposed interventions include the renovation of the whole building envelope, investigated by thermographic surveys, and the installation of new heating and cooling systems. The results were analysed to identify the best intervention for a sustainable energy renovation of the historic building, taking into account the preservation of its architectural values and making it suitable for modern use.

Improving energy efficiency and Indoor Environmental Quality in the School of Mathematics at the Sapienza University campus in Rome

“…In order to assess the Indoor Environmental Quality (IEQ) of the School of Mathematics, seasonal measurements of temperature, relative humidity and air quality have been carried out; the monitoring campaign took place in the summer, autumn and winter season [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] of the epidemiological emergency" throughout the national territory which has, among others, precluded access to the university for months). The direct method was used, based on measurements approached with specific instrumental analysis techniques, carried out during inspections over several days, and by integrating the obtained information with data detected by the "Regional Environmental Protection Agency" (ARPA) of the Lazio Region for the same days.…”

“…The School of Mathematics school is part of the building system of the University of Sapienza [12-13-14-15]. So, it is essential to analyze the behaviour of the entire complex and then focus on the single building [16][17].…”
