Project summary
The health-centre "Alzheimer Project", promoted by the Spanish Reina Sofía Foundation, is a national reference health, training and research centre devoted to the Alzheimer illness. It comprises several buildings such as a hospital, a daily outpatient's department and two buildings for training and research, with a total area of 18.500 m2. In the highest building (research building), and therefore with a highly representative value, a PV façade made of 400 PV lamellas has been integrated as a second skin for sun and thermal protection to the building. 3 different types of lamellas have been custom-designed, in order to be optimally integrated into the building envelope.

Best practice project
The project has been awarded in 2007 as best practice ("emblematic energy project") by the Regional Government of Madrid (Comunidad Autónoma de Madrid)

Special PV project info
PV architecture and building integration400 PV lamellas of 3 different types (glass-glass type) have been integrated in 25 rows in the south-east and south-west façades (also the north-west façade includes non-active lamellas, for aesthetical reasons). The supporting structure is made of aluminium and is separated from the main building façades 80 cm., thus forming a second protective skin. Tilt angle of the PV lamellas is 60º, and vertical distance between the lamella rows is 45 cm., in order to minimise shading losses. To that aim, also the electrical configuration of the PV lamellas has been especially designed, with two independent strings of solar cells connected in parallel.
