Survey of Climate Conditions for Demonstration of a Large Scale of Solar Energy Heating in Xi'an

摘要

A special Energy-Efficiency Plan, for medium and long-term periods, was brought forward by the National Development and Reform Commission of China in 2005. Energy efficiency in buildings is highly emphasized in this energy planning. The Ministry of Finance, together with the Ministry of Construction P.R.C, is selecting cities with different climates to carry out demonstrations of renewable energy applications in buildings. Xi'an, a representative city in the West, is selected to demonstrate large-scale solar energy heating applications in urban residential buildings. In this paper, Xi'an's geographical situation and climate conditions are fully analyzed. The survey on solar energy resources, and the feasibility of solar energy heating on a large scale is also investigated. If this project is completed, the successful experience with respect to the solar energy application in Xi'an will be disseminated in the northwest regions of China. It is expected, after completion of this project, that design methods, procedures and installment of solar energy applications in residential buildings in Xi'an will be obtained.
