ITALIAN SPECIAL New opportunities for

Italy – il Paese del Sole – the country of the sun. Hardly any other country in Europe seems to show such favourable boundary conditions for the development of solar thermal. High solar irradiation levels and high prices for conventional energy come together with an enormous technical potential for solar heating and cooling and a society with a big buying power.

ut only in the last years Italy catches up with the other European markets, mainly driven bottom-up by interested end-users, active enterprises and local promotion ini- tiatives. Expectations are high, that the new Italian government will back-up this new growth with a national development pro- gramme à la France or Spain, in order to ensure quality Binstallations and a faster, but sustainable development of this sector.

Permission procedures in protected areas The average age of the Italian building stock is high compared to other European countries. Many urban and rural areas are protected by specifi c monumen- tal or landscape preservation laws. The installation of solar collectors in these areas is often hindered by particularly rigid building codes. These liabilities could be directly on the building (e.g. historical build- ings) or on the area where it is installed, e.g. parks, coastal areas, etc. »The bureaucratic procedure for permitting solar thermal in protected areas is very costly and it often leads to negative exit«, emphasises Sergio D’Alessandris, president of Assolterm. In order to install a solar thermal system when liabilities are present, an offi cial permission request to all the interested actors is needed, e.g. Cultural For fi ve years this collector Heritage Department (CHD), Park Administration, fi eld supplies the public sport are more diff used.

Regional actions drive the market

It is doubtless that what Italy missed so far in the devel- opment of its solar thermal market is an integrated and comprehensive approach to the problem. No consistent strategic vision has ever been proposed at a national level. Due to this reason and also to the fact that regional governments have strong power on energy issues, the development of solar thermal has been so far led by lo- cal actors, such as regions, provinces and municipalities. This is the main reason of the birth of several regional sion in the medium and long term, which could give the sub sidy programmes and, more recently, of the so cal l- solar thermal sector a comprehensive approach.
