The event Solaris #03, held on the 5th of July 2019, was an opportunity to talk about solar energy in the architectural field and to launch and present the activities that the University of applied sciences and arts of southern Switzerland SUPSI and Eurac Research in Italy are carrying out both at European and international level.

Among such activities,the research projects funded by the European Union Interreg Alpine Space ATLAS, on the energy rehabilitation of historic buildings and the Interreg VA Italy-Switzerland "BIPV meets History", aimed at integrating photovoltaics in historic buildings, were presented along with the Task 59 initiative of the International Energy Agency (IEA). The integration of photovoltaic in historic buildings and protected heritage areas is now of public interest: the Federal Office of Culture recently set out in the official document "SolarKultur", some guidelines on how to better combine solar energy and construction culture in Switzerland. The document illustrates how Municipalities can reconcile photovoltaic and quality construction. Furthermore, it highlights the importance of considering solar energy while renovating the existing building stock.

Following the event, a round table was held allowing all participants to debate this specific issue together with representatives of local authorities. The objective of the round table was to initiate a dialogue between the various players in the territory from Ticino and the neighboring areas of Lombardy, Alto Adige and Bolzano, on the potential for recovery of the existing building heritage and on the opportunities for integrating solar energy into historic and heritage buildings.

The conference and round tables gave the opportunity to key actors in the protection of the landscape and cultural heritage such as architects, researchers, solar companies, trade associations and cantonal offices to discuss the theme of solar energy in existing built heritage. For the occasion, the magazine Solaris # 03 by Hochparterre AG and the web platform www.solarchitecture.ch, were also presented.

The event was organized with the support of the BIPV meets History research Project, under the Interreg V-A Italy-Switzerland Cooperation Program, co-funded by the European Union, European Regional Development Fund, the Italian State, the Swiss Confederation and the Canton of Ticino.
