High-tech Facilities

National Stadium key design plans require that "the design of the National  Stadium should fully implement high technology, which includes information  technology and environmental protection technology. As a new facility, the  National Stadium shall incorporate people-oriented information services,  convenient and reliable means of communication, a comfortable environment and  solid security through reliable, mature, and sophisticated high-tech  construction efforts. Its structure must take into account environmental  protection, energy economization, intelligent services, enhanced communications,  and a relaxing environment. As a reflection of the times, the Beijing Olympic  venues are a window allowing China to display high-tech achievements and  strength."

National Stadium planners applied scientific and technological achievements  to its architectural structure. This includes unique concepts in energy saving,  environmental protection and intelligent building design.

1) Through advanced technology and experience with regards to National  Stadium construction, technological innovation has become the driving force of  the "three ideas."

2) During the design and construction process, a number of key scientific  research projects were undertaken in order to resolve problems. As such,  application of mature technologies in the professional design allowed the  stadium to embody first-class construction and operation.
