SOLID keeps it hot and cold: United World College of South East Asia (UWCSEA),Singapore
UWC (or the United World Colleges) is a global network of schools and educational programmes with the shared mission of “making education a force to unite people, nations and cultures for peace and a sustainable future”.
To satisfy the needs of growing numbers of pupils and students the United World College of South East Asia (UWC-SEA) has developed a second campus in Singapore in 2010. The inaugurated East Campus has a size of 60,000 m² and can house 2,200 pupils. It facilitates a wide range of infrastructures such as workshops, laboratories, audio studios, theaters, libraries, cafeterias, dorms, sports grounds as well as green recreational areas for students and staff. This East Campus is a light-house project not only for educational services but also for the state of the art environment and climate protection technologies applied.
The solar thermal collectors with a total area of 3,872 m² generates “green” energy of 1,600 to 2,200 MWh per year over 25 years. SOLID installed large scale solar thermal collectors, which are especially suited for high temperatures. With a size of 9– 12 m² per panel, it is technically suited to realize larger collector fields and fits perfectly in transportation oversee containers.
For cooling purposes, a Lithium-Bromide absorption chiller with a cooling capacity of 1,470 kW is used. In 2011 this was the most powerful solar cooling system worldwide.
Furthermore, the solar system supplies 100% of the hot water energy demand. A hot water buffer tank of 2x30m³ and a domestic hot water tank of 7 m³ allow for sufficient energy management. Hot water supply is operational since August 2011, cooling since October 2011.
The plant has been developed as Energy Service Company (ESCo). UWC-SEA signed a contract with SOLID on energy services delivery for cooling and heat. UWC-SEA is paying comparable prices for cooling energy from SOLID as it would pay for conventional cooling.
