One building, one system
The goal in a smart building is not to install functionally independent subsystems but subsystems that will interact with each other. For example: The alarm system can cooperate with the shading system and we have a clear indication if a roller is closed or not.
The safety system’s magnetic contacts can prevent the air conditioning system from operating with the windows open. The fire detection system can affect the opening of electric shutters
and the release of evacuation passages of the building.
Smart cameras can prevent an intruder from working with your perimeter lighting system.
Electricity measurements can recommend milder operation
electrical circuits based on the current electricity tariff. Excess electricity can be channeled into the electric vehicle and more efficient charging can be achieved. The energy provided by the sun can exclude the operation of heating water with fuel or electricity
