Governments are committed for decreasing greenhouse gases emissions to accomplish with the global world set targets and towards NZEB, Net Zero Energy Buildings. Since new construction in Europe amounts only a small percentage of the total building stock, emissions from existing buildings cannot be ignored and it need to be reduced. Historic buildings, located in inner cities can also have room for some energy improvements, even across compliance with some modern standards and new construction techniques without damaging their main valuable architectural features. However, to meet these energy requirements it is necessary to promote the use of solar energy also on existing buildings, with or without particular historical values. This matter should thus become a top priority for mid-term future but today it is still not being properly exploited because of psycho-social barriers and lack of information. This paper presents some experience and the lesson learnt from different research projects carried out in Switzerland by the Institute for Applied Sustainability to the Built Environment (ISAAC) to promote energy efficiency and regulate the use of solar energy system, such as PV, solar thermal and solar passive systems, on historical buildings. These research projects have enabled ISAAC to establish specific measures to integrate properly these solar systems with the collaboration and special contribution of different and same time divergent field experts.
