Spain’s first Passivhaus Premium building

Sant Joan de Lebritja


Terravita Renovables created the installations at Can Tanca, awarded Passivhaus Premium certification by Germany’s Passivhaus Institute, the highest and most prestigious building energy efficiency standard. It is the first building in Spain to receive Passivhaus Premium status and only the second in the world.

The 210 m2 house is not connected to the electrical grid. A photovoltaic solar power system generating 11.000 kwh/year ensures a stand-alone supply. An accumulation system guarantees a constant supply of solar generated power. It also has an aerothermal system for domestic hot water, cool roof technology and a high efficiency dual flow mechanical ventilation with heat recovery system (MVHR). Domotic installations allow for energy consumption to be programmed in accordance with requirements.
