Sustainable Renovation of Historical Buildings (SuRHiB)
Example of an historical building in Grüsch (Graubünden) with PV installation. Solar Agentur, Prix solaire suisse 2009.
Scope of project
Historical buildings count for about 20 % of the existing building stock. Most of these buildings have been built during the 19th century and at the beginning of the 20th century. Many of them are not protected buildings but they are characterizing the centres and history of European cities and are part of our cultural heritage. However, these buildings, if normally heated, cause relatively high energy consumption. Without improving the energy efficiency of historical buildings, this part of our building stock providing 20 % of heated space would be responsible for about 60 % of the thermal energy demand of the total building stock (assuming, the other buildings will be retrofitted according ccem-retrofit).
