NEDO, Yasui Architects & Engineers, Inc., Pacific Consultants Co., Ltd., and Sanki Engineering Co., Ltd. have completed the installation of an energy-efficient system at the new Stem Cell and Regenerative Medicine Research Facility in Shanghai, China. The building was constructed by the Shanghai Advanced Research Institute for a project to demonstrate an energy efficient building. On July 20, 2017, a system completion ceremony was held by the Shanghai Advanced Research Institute and NEDO. Japan's energy conservation technology was introduced during the building's design phase, and a demonstration of the system will start soon. The aim of the project is to realize energy saving of 40% in air conditioning and lighting use compared to conventional systems.

Since China ranks first in global energy consumption, energy and environmental conservation are urgent priorities for China and it has announced that comprehensive improvement of ecosystem quality is a major goal in its 13th Five-Year Plan. At a time when high-rise buildings are being built mainly in major Chinese cities as a result of recent high economic growth, the proportion of tertiary versus primary industries is also increasing. Awareness of energy conservation is therefore increasing not only in the manufacturing sector, but also in the building sector.

Against such a backdrop, NEDO, Yasui Architects & Engineers, Inc., Pacific Consultants Co., Ltd., and Sanki Engineering Co., Ltd. introduced a building energy management system (BEMS), which can comprehensively monitor and control energy-efficient equipment with energy-saving technologies to optimize energy consumption, at the Stem Cell and Regenerative Medicine Research Facility (total floor area: 16,000 m2). Construction of this building was recently completed in Pudong New Area, Shanghai by the Shanghai Advanced Research Institute (SARI), which was jointly established by the Chinese Academy of Sciences (CAS), China's largest national research organization, and the Shanghai Municipal Government, for a project to demonstrate an energy efficient building. Prior to the start of the project's demonstration phase, a ceremony to commemorate the installation of the energy-efficient system was held by SARI and NEDO on July 20, 2017.

As the building has energy requirements unique to research facilities, such as 24-hour continuous operation and a constant fresh air system for cooling rooms housing animals, its primary energy consumption* per unit area is higher than that for a typical office building. For the project, Japan's energy-saving technology has been introduced from the building design phase, with the aim of reducing energy use by about 40% for air conditioning and lighting compared to conventional systems. The project also aims to demonstrate a level of energy saving nearly equal to that achievable for a general office building while meeting the special operational requirements for an advanced research facility.

Comparison of energy consumption between the project system vs. a conventional system
- Conventional system

* Assuming energy consumption in the same building using a conventional system

3,450 MJ/m2year
(55.3 TJ/year ÷ 16,000 m2
- Demonstration system

* Expected level of energy saving achieved by the equipment introduced in the project

2,090 MJ/m2/year
(33.4 TJ/year ÷ 16,000 m2)
-40% compared to the conventional system
- Ordinary office building

* Typical office building which conforms to the Zero Energy Building standard in Japan

2,030 MJ/m2/year

During the demonstration phase, building operational data will be collected until March 2018 to validate the efficiency of the energy-saving technology. NEDO will also carry out technology dissemination activities, such as seminars, taking advantage of this project as a model case for an energy-efficient building, with a view to participating in smart city development programs planned for various locations around China in cooperation with CAS.

2.Details of Demonstration

The project will not only show that Japan's energy conservation technology can be effectively utilized in China, it will also demonstrate the integration of technologies provided by Yasui Architects & Engineers, Inc., Pacific Consultants Co., Ltd., and Sanki Engineering Co., Ltd. with the overall aim of showcasing state-of-the-art technology in the energy conservation field.
