Solar Potential Assessment Of Residential Areas

In recent years,with the development and expansion of cities,energy consumption has been increasing,resulting in a large number of urban energy shortage and environmental pollution.As a clean and renewable energy,solar energy has the advantages of inexhaustible and pollution-free.The application of solar energy in urban buildings can replace fossil energy and achieve energy conservation and emission reduction.At present,China’s use of solar energy is more embodied in the building,lacking the research on solar energy utilization in the urban block scale and the overall scale of urban planning and systematic evaluation system and research methods;For practical engineering projects,there is no design strategy for solar energy utilization.This paper is intended to build evaluation system and method of solar energy utilization in urban block scale,with wuhan city as an example,in wuhan city center to evaluate the potential of solar energy utilization of residential areas,map of potential of solar energy utilization,solar design strategy is put forward,at the same time,in view of the new residential areas,analyze the influence of layout form,plot ratio,building density and other factors on the potential of solar energy utilization,and put forward design strategy.This article from the definition of the potential of solar energy utilization to block scale building radiation resource acquisition,threshold calculation of solar radiation,solar installation potential assessment and comprehensive benefit assessment of the potential of solar energy utilization,established a complete set of solar energy utilization potential evaluation system and method.Then based on the evaluation system and method for existing and new type residential blocks do solar energy utilization potential evaluation,it is concluded that solar design strategy,designed for urban planning and architectural designer to provide the corresponding reference.
