Energy performance of building

Control of HVAC systems may reduce congestion of the electricity grid on district level by shifting energy demand of buildings and increase the self-consumption of local photovoltaic energy. To achieve an optimal control of ventilation, occupant behaviour should be taken into account. To describe occupant behaviour, usually black box models are used and typically need large amounts of high quality training data. Alternatively, use of physical relations allows for a good predictive power requiring less training data.

The general practice for establishing the consumption in asset ratings of a building consists of entrusting the energy analysis of the shell of a building to calculating software. The building is the subject of an extremely complicated analysis, and there are many variables at stake, is it more correct to aim for a simplification of the problem, in the knowledge that behind every analytical formula there is the possibility of an evaluation error, or is it better to aim for calculation models that are more and more detailed in an attempt to succeed in predicting the real energy behaviour of
