Siemens helps school in Singapore become greener

UWCSEA employs technolgy from Siemens for existing installations as well as for a new project for energy-efficient office buildings.


United World College South East Asia (UWCSEA) in Singapore is a kindergarten through 12th grade school with two campuses – Tamoines and Dover – for well over 5,000 students. The school’s curriculum places great value on sustainability.

The UWCSEA campus in Tamoines in the east of the city-state has a won a Building and Construction Authority Green Mark Platinum. In the last few years, school administrators have been concentrating on getting the older Dover site Platinum certification as well. This means making all the functions – heating, ventilation- and air conditioning, lighting, room automation, energy management, fire safety and security services – as efficient as possible. Furthermore, the school has partnered with ETH Zurich university for science and technology and Siemens on an innovative project for office buildings.


A first step was the installation of the building management platform Desigo CC at the Dover campus as well as the web-based energy management platform Navigator. Furthermore, Siemens Demand Flow chiller plant optimization solution from Siemens was installed.

The Dover campus is also home to an office building constructed according to the “3for2” concept, which allows building developers to construct three floors within the standard space of two floors without any impact on the perceived floor-to-ceiling height. The office, which opened in January 2016, is equipped with Desigo CC as well as Desigo Total Room Automation (TRA) room operator units and controllers for HVAC and lighting. The office space will serve as a living lab for researchers from ETH Zurich and Siemens.


  • Desigo CC collects data and presents it on a single platform. With the data, informed decisions can be made regarding the management of the buildings.

  • Demand Flow optimizes all energy-consuming components controlled by the system algorithms. The solution is expected to provide the school with energy savings between 20 and 50 percent.

  • Desigo Total Room Automation (TRA) among others switches lights on or off depending on natural light entering a room and the information received from presence detectors and integrated brightness sensors.

  • 3for2 concept: Researchers from ETH Zurich are using Desigo CC to monitor energy consumption over the next two years to determine the design’s impact on energy consumption.

Facts, 3for2 concept

The 3for2 concept developed by ETH Zurich allows three floors to fit into the space normally needed for two without reducing the usable room height. Some background information: In conventional buildings, up to a third of the enclosed volume is occupied by air conditioning equipment and ductwork for transporting dehumidified cold air. In contrast, the 3for2 concept uses low-profile, ceiling-mounted chilled beams for space-saving, low-noise water cooling, as well as distributed chillers behind the façade and LED lighting panels. This technology lowers both energy needs and construction costs. Since the building’s official opening, energy consumption in the 3for2 space is among the lowest in all of Singapore.
