Present Situation Analysis And Optimization Strategies Of Residential Solar Access Rights In Harbin

Clean and pollution-free energy is paid more and more attention as a result of the increasingly serious problems such as energy shortage and environment pollution.As a kind of inexhaustible,clean and pollution-free energy,solar energy has been got more and more favour of people.In the construction of urban residential districts in China,solar energy utilization is more close to people's life with the concept of the solar energy residential district and the ecological residential district.At present,the laws and regulations related to the solar access rights in China are all on the basis of sunshine lighting time of buildings.The protection of the right of daylighting,is usually realized by controling the distance of buildings,but no clear rules about the quality of the solar has been regulated.Therefore,it is necessary to put forward corresponding standards of the use of solar energy,to guarantee the right of residents to obtain and make use of solar energ y.This research proposes the concept of solar access rights.Through the investigation and survey of urban residential districts which are constructed during from 2006 to 2016 in Harbin,four kinds of typical patterns of Harbin residential districts are determined.Solar access conditions of residential buildings,public buildings and public spaces in each pattern are simulated and analyzed,achieving the solar access conditions of different patterns of Harbin residential districts.On the basis of the simulation results,the method of solar envelop is introduced into China,and the correction method is put forward to make it applicable to conditions of China.Besides,based on the solar access rights,the study raises the optimal planning strategies of improving the solar access of residential buildings,public buildings and public spaces.By drawing lessons from solar access policies and calculation methods in western developed countries,and combining with the actual situation of Harbin,this paper is aimed to achieveing the index that is suitable for Harbin residential solar access rights with simulation analysis,and putting forward the planning and design strategies of optimizing the residential solar access conditions.The study of the control strategies of Harbin residential solar access rights will also provide a reference to residential planning in other areas of China,leading more and more residential development towards the direction of the ecological and energy saving.
