A system and method for maintaining a system configuration to provide desired system performance is disclosed. The system comprises a processing unit receiving sensor data associated with environmental conditions within an area, generating a map of the area based on the received sensor data, determining a change in the map of the area and determining at least one system commissioning parameter associated with the determined change in the map to compensate for or correct the change in the map. In one aspect of the invention, the sensor data is provided through a plurality of mobile devices.

The invention relates to a light control system (120;121) for controlling a lighting system (100). The light control system (120;121) is arranged to receive a power reduction parameter (alpha). The light control system comprising a light controller (134) arranged to receive a measured light value from a light sensor (127), to determine a light channel level value depending on the measured light value and a calibrated setpoint value if no power reduction parameter has been received, and to determine a light channel level value depending on the measured light value and a scaled calibrated setpoint value if the power reduction parameter has been received, the scaled calibrated setpoint value being equal to the calibrated setpoint value multiplied by the power reduction parameter. A load controller (135) is arranged to receive the light channel level value from the light controller, to determine an output level signal depending on the light channel level value if no power reduction parameter has been received and to determine a scaled output level signal if the power reduction parameter has been received, the scaled output level signal being equal to the output level signal multiplied by the power reduction parameter, and to send the output level signal or the scaled output level signal to drivers of light sources of the lighting system.

A system for managing provided services is disclosed. The system receiving information regarding measureable events, determining a distribution pattern of the measureable events, determining an identity of a user based on the distribution pattern and providing instruction to controllable devices to alter surrounding conditions based at least on the identity of the user. In another aspect of the invention, the controllable devices may represent a second set of sensors that are used to collect data of a second type. The information collected from the second set of sensors may be used to determine a health status of a user.
