As for the economy of green buildings, this paper USES relevant technologies to analyze and verify the economic benefits of green buildings so as to further promote the sustainable development of green buildings.For the economy of green building, usually, main show is: green building economy through economic value, directly to the economic value can be through the financial costs and benefits calculation simple calculation. For example, in the construction stage, the investment of thermal insulation exterior walls, energy-saving Windows and other technical measures is the economic cost of energy conservation of green buildings, while the benefit is mainly the economic value of energy conservation in the use stage. The economy of green building can be reflected indirectly through environmental value. For environmental value, it is necessary to quantify environmental pollution, which will be converted into economic value, environmental value, for example, in terms of environmental benefits, usually converts green building energy saving of standard coal, at the same time into the pollution gas emissions, according to the cost of pollution, evaluate the environmental value. Under the influence and restriction of information asymmetry and system boundary uncertainty, it is difficult to quantify environmental value, and it is not easy to calculate accurately. The economy of green building is hidden through social value. By analyzing the development of international green buildings, green buildings originated in the 1970s. They are the products of the green movement in the west. Green movement advocating environmental consciousness, and contains the social justice in the environmental awareness, green building of the values is a critique of the current economic system, its advocacy of environmental benefits and the pursuit of social justice, green buildings to reduce the environmental impact needs public foster a sense of responsibility.The so-called external effects, in a nutshell, is in the process of actual production and operation, the activities of the producers of the impact of other consumers, usually it is a kind of cost or benefits spillover. For green building, its economy on the one hand, is characterized by energy saving on the use of lower cost and other direct economic benefits, on the other hand to reduce the environmental impact caused by indirect environmental benefits, with the help of certain areas are the environmental benefits. Green buildings require investment in technology costs, and the society shares the environmental benefits of green buildings, namely the external effects of green buildings.留学生写作网（www.pnstudy.com）-专业留学生作业辅导中心留学生写作网（pnstudy）为留学生提供高效、优质的论文服务Time effect refers to the happen now with the same amount of costs and benefits, compared to the value of future costs and benefits are relatively low, generally, the longer the time apart, its present value will be smaller. Discounting is the process of adjusting future costs and benefits to present value. The reasons why people use discount mainly include two aspects: time preference and opportunity cost of capital. The so-called time preference refers to that everyone likes to benefit before spending, while the opportunity cost of capital refers to the higher value of capital now than the same amount in the future.Considering the impact of green buildings on the environment from the whole life cycle of buildings, generally, it mainly includes the collection, processing, transportation, construction, use and decomposition of building materials. Take the energy consumption of buildings as an example. Compared with buildings, the energy consumed by building materials is equivalent to the total energy consumed by building materials for 3-5 years. The energy consumed in the use of buildings mainly includes energy consumption in heating, air conditioning, ventilation and other aspects. Of the total energy consumption of buildings, the energy consumption of heating and air conditioning ventilation accounts for about two-thirds. Therefore, improve building thermal performance usually can cause long-term economic benefits, in this process, although can increase the part of the building materials and energy consumption, but compared with the cost of building phase or less.To 2000, both the housing area in China, the city has reached 7.66 billion m2, 20.04 billion m2 of
