Research On The Life-Cycle Of Green Building Optimal Decision Model

With the concept of sustainable development in the construction of the deep, green building began much attention. Establish a green building can actually preferred decision-making model to promote green building development. Home and abroad on green building assessment study after many, but for project decision-making phase of the analysis is sparse. This paper studied the contents of the green building life cycle from the point of view, to consider green building construction than the traditional incremental costs and the environmental benefits of green building, economic benefits, a comprehensive analysis of green building.The paper first in-depth study of domestic and international green building technical measures based on the green building evaluation criteria selected for the festival with the outdoor environment, energy conservation and energy use, materials and material use, water conservation and water use, indoor environmental quality and operational management of the typical technical measures. Then according to the environment, resource economics, theory and cost-benefit analysis of green building features, costs and benefits separately for quantitative analysis, the establishment of the Chengdu area green building (residential) cost-effectiveness of the relational database. Finally, a cost benefit analysis, the establishment of a full life-cycle based on optimal decision-making model of green building, through the use of advanced technology, comprehensive analysis of green building, green building and more traditional architecture of the building cost differences and benefits of the differences, for the use of green building technology companies in a project feasibility study report to provide cost-effective number of information theory. Developer is to provide decision-making model based on this analysis the cost-benefit information, to determine whether to adopt the decision to invest in green building technology, customers can buy based on whether it is to make the decision, the Government can also be used to evaluate the use of comprehensive green building projects bring social benefits.The innovation of this paper: the model can make up for green building assessment method does not apply to construction projects, lack of feasibility study stage, to help select the best benefits of green building development plan. Green building investors, customers and government cost-effective quantitative information; clear green building with traditional architecture, cost, efficiency differences, accelerate the construction of sustainable development.
