The Başakşehir Çam and Sakura City Integrated Health Campus located in Istanbul (Turkey) collaborated with Yanmar to become more energy efficient, reduce energy costs and CO2 emissions. Supported by the Turkish Health Ministry, Yanmar installed a large trigeneration facility to provide the hospital with low-carbon electricity, heating and cooling. As the hospital has a bed capacity of 2.682 and about 1.000.000 m2 of closed construction area in a seismic area, the project was called “The World’s Largest Building with Seismic Isolation” thanks to the 2040 seismic isolators.
The power plant contains 5 gas generator packages with a total capacity of 12.180 kW electrical output from the Spanish brand Himoinsa, a group company of Yanmar. The plant was commissioned in May 2020 by Yanmar Turkey, a member of the Turkish Cogeneration Association and its regional representative, under the challenging conditions posed by the COVID-19 pandemic.
At the facility, 11,496 kW of heat will be obtained and converted into hot water of 90°C using jacket water exchangers and exhaust-effect chillers. If the facility requests, 6°C cold water with a total capacity of 6,928 kW will be obtained via the exhaust-effect absorption chiller. The trigeneration plant helps the hospital meeting its 40MW electricity and 32MW cooling loads in summer as well as the continuous 12MW electricity and 7MW cooling needs at every moment of the year.
The overall efficiency of the system reaches 90% via the heat recovery when electricity is generated. This results in annual energy cost savings of 1,8 million EUR and a 60% reduction of CO2 emissions.
