ABSTRACT




At present, the total area of approximately 4.5 billion square meters of public buildings in China, 99% of which buildings are energy-intensive While still at the peak of construction, new housing nearly 2 billion square meters a year, exceed the sum of the volume of all construction in developed countries and in new buildings, still has more than 95% belongs to energy-intensive building! Because the consideration during the design phase is a one-time investment cost, less consideration of the finished construction?ˉs use fee?￠maintenance fees?￠ and after expiry of the project scrapped demolition charges￡?this will make the whole life cycle of the project is not necessarily economic￡?And the Combination of technical and economic is not close enough and so on. Point at these problems currently existing in the public architectural design and the importance of architectural design in the project life-cycle , this paper proposed solution of value engineering theory￡?using life-cycle cost modeling and systematic functional analysis techniques￡?quantitative and qualitative eva luation of design.

First, paper introduces the value engineering?ˉs principle￡?public architectural design stage of value engineering organization and the procedure value engineering activities?￡Value engineering?ˉs work plan provide from the beginning to the conclusion of the study carrier. Work plan for value team provides all information required for a research grant and for value team's creative work and analysis of alternative scheme provides sufficient time, so the project team can select the best alternative.

Second￡?reviewed the developments in the theory of full life cycle costs￡?put forward the necessary of full life cycle costs theory in the public architectural design stage, component analysis of life cycle cost and life cycle cost calculation method￡?to achieve the aim of project life-cycle costs.

Then, the paper describes systematic functional analysis techniques. Functional analysis is the analysis of the system of mutual relations of powerful graphics tool, help value team members develop thinking, grasp the necessary function, find unnecessary function. Systematic functional analysis techniques embody the characteristics of functional analysis. Functional analysis is to determine whether using value engineering method in the project's most basic problem.

After that, use the value engineering in project, through the practical application of the value engineering in the public building design phase, from the perspective of practice set out in the application of value engineering in the design getting great economic and social benefits.

Finally, get the result. Value engineering as a combination of technical and economic methods exactly catering to the lower cost, improve the performance of goal pursuit, played a great efficiency in the public architec..
