Monitoring and control system for smart buildings based on OPC UA specifications

The fast development of green buildings that are focused on saving the energy consumption and using the renewable energy resources has led to an accelerated development of solutions for remote monitoring and control of the smart buildings. This is a consequence of the huge market potential for these solutions. This paper presents a solution for monitoring and control of smart buildings based on OPC UA specifications. The system that integrates the MODBUS and BACnet fieldbuses, it can be distributed on the Internet, and it uses the security from the OPC UA specifications based on the security certificates.
