Study On The Economy Of GSHPs' Application In The New Buildings And The Policy Suggestion

Because of limitation of resource, high cost of buildings, the energy conservation has become the important content in the buildings energy strategy every country in the world. China is now in the stage of urbanization and rapid development of industrialization, in the next 15 years, the increasing buildings is about 2 billion m2 every year, but it can't satisfy the request of buildings energy conservation in the word only depend on 50% or 65% of the design standard of the energy conservation in the present and the fact is that it can not reach this design stardard now. Therefore, considering the application of renewable energy such as Ground-Source Heat Pump systems(GSHPs) etc in the construction field is necessary. The application of renewable energies in the buildings can effectively reduce the consumption of energies and will produce large economic benefit and environmental benefit while satisfying the living comfortableness required by the users. The Ground-Source Heat Pump buildings starts early in the foreign countries and many countries invest more for the Research and development(R & D) of this technology and it is relative mature, they also spare no effort in the promotion of it. However the development of GSHPs is at the initial stage in our country, many concerned policies about this technology have been drawed and improved by government, but the speed of its development in the buildings is still slow. Besides the reason of the GSHPs technology and the standard of its assessment at home, the main reason of it is that there is less economic research for the GSHPs and it is also the main reason that restrict the development of GSHPs.This thesis studies on reasons that GSHPs develops slowly in buildings field:The society recognization problem and invested high at the initial stage and policy obstacle. Then according to interrelated economic analysis, come to the result that GSHPs can receive payoff by many partners:applying consumer demand and consumer surplus to analyze GSHPs supply and demand, and we can conclude that it is needed by market and can be a new investment direction,but its market supplies is serious shortage; comparing the economy between GSHPs'and traditional air-conditioning systems',the air-source heat pump systems' using the main factors of economy analysis such as initial investment,operating expenses, the cash discharge method, etc, and the result is that the application of GSHPs in the buildings is the most economic; and finally, the paper give the advice of popularizing GSHPs such as administration policy,law policy,economy policy and so on. The Government is required to implement these policies, and encourage the whole societies to participate to popularize application of GSHPs in the buildings. At last, it gives the conclusion and prospect in the end.The economic analysis and the policy suggestions of GSHPs in the buildings of this paper help providers to know its benefit rightly and invest properly; and help consumers to know and andaccept it and also helps government to promote GSHPs' policies. thus will promote its development in the buildings.
