Taiwanese hospital receives LEED for Healthcare Platinum certification

Siemens helped Linkou Chang Gung Memorial Hospital Proton and Radiation Therapy Center to achieve LEED for Healthcare Platinum certification


Linkou Chang Gung Memorial Hospital (CGMH), located in the district of Linkou, Taiwan, was founded in 1978. The hospital has nearly 4,000 beds and a total of 29 specialty centers. One of the centers is the Proton and Radiation Therapy Center (PRTC), which was the first proton center in Taiwan. CGMH PRTC provides advanced radiation therapy and comprehensive medical care to patients from Taiwan and the rest of the world.


The buildings that house CGMH PRTC were planned and designed by CGMH’s facility team. Siemens was called in to serve as the green building consultant for the center. CGMH is committed to the long-term efforts of sustainability, which was behind the decision to make CGMH PRTC into a sustainable and green place.


Siemens equipped CGMH PRTC with its building management system to make the building’s operations more intelligent and energy efficient. Furthermore, Siemens served as the green building consultant throughout the LEED application and implementation processes.


As a result of these efforts, CGMH PRTC received Leadership in Energy and Environmental Design (LEED) for Healthcare Platinum certification in 2014. Platinum is the highest level possible. CGMH PRTC is Asia’s first and the world’s second hospital to receive LEED for Healthcare Platinum certification.

CGMH PRTC is now 42 percent more energy efficient than regular buildings. Every year, CGMH PRTC saves 2 million kilowatt hours of electricity consumption and reduces 1,224 metric tons of CO2 emissions. In addition, the wastewater recycling and reclaimed water system reduce water consumption by 61 percent or 18,750 tons of water annually.


In order to comply with LEED for Healthcare guidelines, extra effort went into these areas:

  • Heat-resistance: Energy-saving Low-E double-layer glass is used for all external windows, and heat-resistant layers are added to the inside of the walls. In addition to the roof garden, the roof is also covered by a foamed-concrete heat-insulating layer and polystyrene board, effectively enhancing heat resistant efficiency and reducing the need for air-conditioning.

  • Air-conditioning and energy consumption control: Air-conditioning hosts, chilled water pumps, cooling tower fans and air-conditioners are all designed with variable frequency. Energy-efficient controls are installed to ensure easy adjustments to optimal conditions. Moreover, an intelligent integrated system is installed in order to control the distribution and transmission of energy, enhancing the operational efficiency of the chillers, ice storage systems, low-pollution coolants, cool-heat exchangers and heat-pump systems.

  • Lighting design: Two-way lighting control systems are adopted with automatic on-off functions. Energy-saving lamps/light bulbs are installed comprehensively. In addition, the number of lamps are reduced and designed in a way to leverage more natural lighting and to avoid excessive indirect lighting.

  • Renewable energy: The floor slab structure of the roof was strengthened to accommodate solar panels and wind turbines for renewable energy generation.

  • Waste recycling and reuse: Around 98 percent of CGMH PRTC’s construction waste was recycled.

  • Green materials for construction: Most of the building materials are made from recycled/reused materials with low dissipation, formaldehyde-free and non-toxic characteristics. In addition, coating materials are free from lead.

  • Environmental protection: Half of the CGMH PRTC building site is covered with plants and roof gardens. Carpool and hybrid cars are highly encouraged.
