The goal of the system is to operate the building at the lowest energy consumption with small manpower and minimal malfunction time.
The building controlling system contain the operation of the whole technology, the coordinated controlling operations and the information services of the edifice. Adjusting variable temperature demands, lighting controlling of common and outer spaces, efficient shading controlling all could be parts of the whole system. The most effective way using the energy sources when all the exothermic devices (boiler, heat pump, chiller, air conditioner, solar panel) supply the building in a complex system.
Immediate error and status-signing of the electrical and mechanical systems can reduce malfunction time to fragments, so it is very important for good operation.
In order of easier operating, it is useful to integrate the smaller devices into the whole system as well such as individual air conditioners, local water heaters and lightings of advertising, lakes and pools.
