This headquarters of a famous telephone company is located in the center of Athens and consists of two buildings with 4 floors above ground and a garage. More than 500 employees use the office building that also includes a datacenter. Annual energy consumption reaches about 5300000 kw/h of electricity. The project realized focuses on energy efficiency and implements a BEMS supervision system with local and remote management.
Developing the BEMS using LWEB-900Sistemi Integrati, LOYTEC Competence Partner, took care of planing energy audit and an executive project for the new BEMS, the supply and installation of all the DDC components planned, and the construction of the dedicated electrical system, as well as commissioning, start-up and creation of dedicated graphic pages with energy analysis reports. The realized system controls a total number of 1872 lighting fixtures of which 1666 are connected via DALI, 73 VRF air conditioners via BACnet protocol, and 68 power meters via Modbus protocol.
Remarkable energy savings
In the office areas, mostly open space, the automatic seasonal changeover function has been implemented to control individual room temperatures depending on the outside temperature. This controls ventilation and heat recovery in the best possible way and guarantees a maximum comfort to the occupants. Energy consumption can be monitored by implementing the existing power meter switchboards via Modbus communication - installed on the various distribution lines of the individual areas: lighting, driving force, air conditioning, UPS
Energy saving during project planing were expected around 12.8%. Actual energy savings reached 17.4% in 2019 - to the great satisfaction of the customer.
