BMS RETROFIT PROJECT TO REDUCE OVERALL COSTS
Karadeniz Technical University.
The Karadeniz Technical University is a public research university in Trabzon, in the Black Sea Region of Turkey, with a total of 80 departments, 12 faculties and 6 graduate schools. The main goal of this massive retrofit project was the integration of individual heating and cooling systems of 34 departments and 7 external faculties affiliated to Karadeniz Technical University into one BMS. Termmarket, LOYTEC Competence Center in Turkey, created a highly efficient solution with LOYTEC and is honored to win the tender of the Ministry of Energy in Turkey. Before the start of the project, buildings had local automatic control, but in order to detect and correct malfunctions of any kind the technical team had to drive to each building. This was particularly time and cost consuming if you take into account that external faculties are spread over an area of around 40 km.
THE CHALLENGES
Retrofit needed to combine heating/cooling systems into one BMS
BMS solution to achieve lower costs, higher energy efficiency and detect malfunctions faster

Solutions
L-IOB Modules and L-IOB Controllers integrated within LWEB-900
The Solution.
18 of the internal departments, with individual access rights each, use independent boilers, cooling groups, heating/cooling pumps and air handling units. The control and monitoring of these units are handled via the LWEB-900 BMS server located in the heating center. The implemented solution ensures the report of entrance information, the collection of error messages and that each building is controlled based on a central scheduler.
Zone and building visualizations of the internal departments are embedded on each control device (L-IOB I/O Controller). On top of that, all visualization graphics are also hosted on one central LWEB-900 BMS server. External faculty buildings which have their own boiler room and dedicated cooling groups, on the other hand, are connected to the BMS server via a VPN network. In addition, each external faculty has an LWEB-900 client PC with a VPN connection to the server.
The following 7 external facutlies were implemented via VPN
Surmene Faculty of Marine Sciences is 38 km from the center to the campus.
Arsin Vocational School is 28 km from the center to the campus.
Arakli Vocational School is 42 km from the center to the campus.
Maçka Vocational School is 30 km from the central campus.
Of High Technology is 43 km from the central campus.
Surmene Abdullah Kanca Vocational School is 39 km from the central campus.
Trabzon Vocational School is 19 km away from the central campus.
Benefits.
The heating center technical team can now instantly reach all integrated buildings via the LWEB-900 client software and immediately react to any operational changes.
Conclusion.
The customer is very pleased with the cost and energy savings achieved by integrating all boilers, cooling groups, heating/cooling pumps and air handling units in one BMS server. In addition, the new system contributes to improved well-being and higher work and learning efficiency for university staff and students.
Creating the smart buildings of tomorrow - together.
