Building integrated Renewable Energy Sources

The integration of Renewable energy Sources at building level has a high potential to complement the efficient designs of high-performance new buildings in order to achieve low energy districts by reducing the building energy requirements from conventional technologies to a minimum. These building integrated sources allow using local resources, reduce distribution losses and take advantage of the large surface occupied by buildings at district level. The most common examples of Building Integrated Renewable Energy Sources are solar systems in roofs or facades, small biomass boilers or geothermal energy.
