The thermal collectors provide approximately 4200 kWh of energy while
the simulation predicted 4350 kWh. The measured performance indicates
that the solar thermal collectors provide 63% of the domestic hot water
heating. During the summer season the production is even higher than the
consumption while during winter it is necessary to integrate with the GHP
and the auxiliary boiler.
For the calibration of the model, real and monitored interior temperature
and PV production of four particular days were compared. The chosen days
are the following (Torcellini and Crawley, 2006):
- January 24th (cloudy, cold);
