Research On Incremental Cost Control Of A Green Real Estate Project

Since the reform and opening up,the construction industry has become one of the pillar industries of the national economy,which has great significance in promoting the development of the national economy.However,as an industry with high energy consumption and high pollution,it also brings serious environmental pollution problems,which violates China's sustainable development strategy.In order to effectively alleviate this phenomenon,and effectively implement the five development concepts of innovation,coordination,green,development and sharing,the development of green and energy-saving buildings has become the new trend of the future construction industry.At present,the development of green buildings in China is still in the primary stage mainly advocated by the government.In order to further promote the development of green and energy-saving buildings,we should not only rely on the innovation of green and energy-saving technologies,but also strengthen the economic research of green buildings,among which incremental cost is the most noteworthy issue.In real life,green building stakeholders "kill" green real estate projects by focusing too much on the short-term economic benefits generated by projects.The reason is that people think that the cost of green building equals the high cost,which greatly limits the promotion of green building.Therefore,incremental cost is one of the key factors affecting the implementation and development of green buildings.Starting from A green real estate project,this paper divides the incremental cost of green buildings into four stages from the perspective of the whole life cycle,which are the preliminary planning and design stage,construction stage,use and maintenance stage,and recycling and utilization stage.Paper in line with "ask questions-analysis problem-problem solving" the logical structure of the idea,to A green real estate project cost control status quo are described,for the project organization structure of incremental cost control,cost control process,summarizes the problem such as cost control method,using the cost control method of quantitative analysis,and it is concluded that the cost control strategy.The analysis focuses on the following three points: first,build A whole-life benefit model of green building,quantify incremental cost and incremental benefit,evaluate incremental cost and benefit of A green real estate project by using the cost-benefitmethod,and verify the feasibility of the project.Secondly,the incremental value matrix of green buildings is constructed by using the value engineering analysis method,and the way of value promotion is proposed based on the analysis results,so as to achieve the goal of value maximization of the whole life cycle.Thirdly,an intuitive analysis is made of the incremental cost of A green real estate project by using ABC classification method,and the objects analyzed are divided into three categories: A,B and C,and the incremental cost is classified and managed according to the importance of impact.Based on green building incremental cost of empirical studies have found that A green real estate projects in energy saving and energy utilization,water saving and water resource utilization has obvious characteristics of green building project incremental cost accounted for the proportion of the total cost is larger,so choose green technology,in guarantee under the condition of green building design capabilities,incremental cost should be paid great attention to accounted for A large part of the technical innovation,can effectively reduce the cost of green buildings.
