The answer is two-fold. On the one hand, automatic control is preferred to manual control of ventilative cooling because of guaranteed the cooling effect and reduced overheating risk. The effectiveness of occupant manually operated windows or louvres to control ventilative cooling reduces over time. Occupants take less responsibility for maintaining the indoor thermal comfort. On the other hand, case studies show that it is really important that the user can overrule the automatic control of ventilative cooling. Users are satisfied that they are able to control the ventilative cooling system.

It can be concluded that an automated control with the possibility to ignore or overrule this control is the best option for a reliable system with a maximum cooling efficiency as well as a maximum user satisfaction.
