Energie rinnovabili negli edifici e certificazione energetica

According to the European Union, about 40% of the energy consumption and of the 36% of the greenhouse emission in the European area can be ascribed to buildings. It is therefore necessary to firmly operate in the building field in the direction of new concepts and techniques addressed to new near zero energy buildings (NZEB) and to the reduction of the energy demand of existing buildings through suitable retrofit interventions. Energy saving in buildings can be obtained by improving the building envelop (i.e. insulation, passive solar, solar screens, green roofs) or by the use of renewable energies (solar collectors, PV panels, geothermal or solar assisted heat pumps…).
Moreover, to promote the energy saving in buildings, the Community rules and subsequently also the Italians rules require an energy performance certificate for buildings that is obtained by a standard procedure.
The research in this field concerns both the enhancement of the building shell and the use of renewable energies, or the optimized integration of both these aspects, as in the case of the building integrated photovoltaic facades.
A Regional financing has been obtained in the framework of the "Programma triennale per la ricerca e l'innovazione: progetti integrati ad alta tecnologia" of the Polo di Ricerca e Innovazione sull’ Energia Sostenibile in Savona for the project "SMART AGRO-MANUFACTURING LABORATORY (SAM-LAB)". The Project is aimed at realizing an innovative greenhouse equipped with new materials for the glazed shell and with suitable automatic controls which will greatly reduce the energy needs that in turns will be mainly provided by renewable energies.
The Research group has many international relationships with Research Institutes like the Centre d'Energétique et de Thermique (CETHIL) of Lyon, and the Université de Savoie of Chambéry.
The Research group has organized and coordinated for Unige four Advanced Training Courses named “Certificazione energetica degli edifici” for researchers, designers and technicians.
