Economic Evaluation Of Green Building Based On Large-scale Commercial Real Estate

With regard to the popularity of the concept of green, and the current situation that the whole country's construction industry accounted for the total social energy consumption up to 30% and the environment pollution and resource crisis, the government policy to encourage the backdrop, the development of green building has increasingly become the building products trend. Green building can not only lead to increased property income, for example, raising the price of rent or sell; also can bring reduce property costs, such as energy-saving reduces the cost of water and electricity during the operation, and also enhance the brand benefit. In particular, commercial real estate, more and more international high-end brand emphasis more about their stores on green building requirements. Therefore, an increasing number of large real estate developers, regard green building as its operational requirements, while most real estate developers who haven't tapped in this field don't have a clear awareness on green building, most of the concerns of these developers is the s of the green building, secondly is the unfamiliarity of the focus of green building design and the unprofessional of its advisory unit, so from the supply side is concerned, the effective analysis of green building costs and benefits is a useful basis for decision making for developers. It is also an important way to promote the spreading of green buildings.Despite in order to promote the development of green building, China has accelerated the development of green building-related technology system, evaluation system, policies and systems, etc., but in fact we mention more about green building technology, building shopping malls mention more about the green energy-saving design, and with regard to its economic cost-effectiveness, the market has not yet a more standardized evaluation methods. Incremental costs and benefits of green building is within the scope of the whole life cycle, the incremental benefit is more apparent during the operational phase. For developers, commercial real estate and residential real estate is different, the former focus more on operating income, while large-scale commercial real estate has the characteristics of development and operation of centralized management which better reflect the efficiency advantages during the operational phase, and therefore better reflect green building economics.This paper launched a green commercial building economic evaluation based on the perspective of commercial real estate developer. Firstly, paper introduces the research status of green commercial buildings Economic Analysis at home and abroad, then outlines the development process, and divides the cost structure within the green commercial building full life-cycle phases, transfers the users' reduced maintenance costs during the operational phase into rent or sell price increases of the developer; Secondly, paper introduces composition and calculation methods of green commercial buildings' incremental costs and benefits, then quantified the environmental and social benefits which is difficult to quantify as CO2 emissions and other easily measured, also discussed and defined the quotas of green economic assessment of commercial buildings, green evaluation methods to determine the commercial building; At last, in accordance with the six quotas of "Evaluation Standards of Green Store Building ", paper analyzes the economic evaluation of the case, focuses on the economic efficiency and other indicators of land, energy, water, and operational management, determines that in the commercial real estate projects, envelope insulation and efficient refrigeration unit has higher economic efficiency, and mechanical parking can efficiently save the initial investment, also determines priorities for future development of green commercial building technical measures.
