Johnson Controls Contributes to China's First Green Building

Johnson Controls has successfully completed a U.S.-Sino collaboration to provide an energy-efficient headquarters for the Ministry of Science and Technology in Beijing. This project -- thought to be China's first "green building" -- is a pilot to show the effectiveness of U.S. energy-saving technology.

This building was designed in accordance with the Leadership in Energy and Environmental Design (LEED) Green Building Rating System. As the country's first internationally-certified green building, this pioneering project is redefining construction practices in China. Johnson Controls is the most qualified controls company, able to help its customers to obtain the LEED certification rating.

The energy efficiency design and the technology contained in the Ministry of Science building will deliver huge benefits to China, the world's largest construction market. The World Bank estimates that nearly half of all building construction over the next two decades will occur in China.

The floor area of the project is 19,000 square meters, including nine floors of office. Johnson Controls installed a Building Automation System, using Metasys(R) software for energy management. The software successfully manages the heating, ventilating and air conditioning systems, lighting system, electrical system and the elevators.

Among the energy-saving features are: fresh air and air handling units are controlled by a frequency converter; air volume is delivered on each floor according to specific needs; fresh air goes through heat conversion so that the exhaust gas can be exchanged with the fresh air and the fresh air can be preheated in winter; air volume can be controlled through measuring the temperature and humidity together to make appropriate adjustments.

According to Spencer Abraham, U.S. Secretary of Energy, energy usage in this building is approximately 50% less than comparable office buildings in Beijing. Energy efficiency improvements of this magnitude are important because buildings consume more energy in China and the U.S. than any other sector. Economic growth, environmental quality, and energy security all depend on making buildings as energy and resource efficient as possible.
