The overall balance of energy within the building is positive. That means, that the solar power system generates more energy than is needed for power supply and heating of the building itself. Excess energy can be used directly for charging the university’s own electric car.
The building is equipped with sensors and actuators as well as bus-systems and building control technology which allows for adjusting settings and reading out of counters and meters. All the data is stored in a database. The historical data can thus be used at any time for balances and comparisons in order to serve for a more efficient use of the energies in the building.
