The Study Of Integration Design On Solarbuilding In Hunan Area

Since the 1970 s,due to the aggravation of energy shortage and the recognition of environmental issues,solar energy has been widely concerned as a widely distributed sustainable energy source.In the 21 st century,because of the progress of technology,and introduced incentives in European countries,there are more and more solar equipments installed in buildings as technology advances and national policy incentives.However,due to the difference between climatic conditions and solar intensity between different regions,solar energy equipment and construction combine need to solve the problem of local conditions.Therefore,the design of solar energy and building integrative design in Hunan has important practical significance.This paper verifies the feasibility of solar energy building integration by analyzing the natural conditions,solar energy resources and the current situation of development in Hunan area.Most areas of Hunan Province have relatively abundant solar energy resources,photovoltaic industry has been developed under the support of policies.Solar buildings in Hunan Province have a huge potential for promotion.Collect different types of solar building design strategies and technical measures.The principle and integrated design type of passive solar energy utilization and active solar energy utilization are expounded.And different types of architectural integration design were combed and analyzed.The effect of climate environment on the effectiveness of passive strategies in Hunan Province is demonstrated by the energy consumption simulation software climate.The benefits of different passive strategies are analyzed from the indoor thermal environment.The quantitative comparison and qualitative analysis are carried out.Through calculation and simulation,the optimization principles of photovoltaic,photothermal and other active equipment in Hunan area are obtained.Finally,through the 2018 China international solar decathlon competition platform,the solar energy building technology optimization principle is directly applied in the design of the construction scheme,which directly demonstrates the feasibility and economy of the integrated design of solar energy in Hunan province.
