Cluj (Romania)
Renovation of students accommodations
The Romanian demo site consists of the renovation of the student dormitories at the Technical University of Cluj-Napoca. The use of additional renewable energy sources, like BIPVs façade panels and an innovative “geothermal wall”, will transform the renovated section of the student’s accommodation into a positive energy building. The energy surplus generated will be shared with the neighboring buildings (other dormitories, the food court, etc.).
