With the improvement of the quality of building requirements, the concept of green has been more or less used in the architectural design. This chapter focuses on the combination of BIm and natural lighting technology in the CSC Plaza project, and studies how to use the BIM model combined with the relevant software to carry out the whole process of natural lighting.

BIM (Building information modeling) is one of the most advanced technologies in the building industry, whose value in the design and construction stages has been agreed by increasing number of companies.However, BIM is not widely applied during the operation and maintenance phases, and the value has not been identified clearly due to various of reasons.This paper explores the BIM+FM (facility management) technologies by studying Zhongjian Square project which applied BIM+FM technologies such as space management, assets management and building systems analysis during operation and maintenance phases.

With the development of the new technology, the architectural design has reached an unprecedented level in building industry.The advanced technologyallows new design approach and concept to be realized, and also providesgreat vision for betterarchitecture aesthetic, technology research and building construction method.This paper explores the 3D design methodologyonthe cooperation platformthrough a casestudy of theice world project in Changsha.Byestablishing the project database of building components, the virtual expression of complex building shapecan be realized, which is able to apply the idea of prefabricated architectureto complex shaped buildingssuccessfully.
