The Design Of Passive Energy Saving For Public Buildings In Severe Cold Areas Of GanSu Province

In recent years,green passive buildings have become the main theme of the development of China’s construction industry during the period of new urbanization,especially in the cold and cold regions of Gan Su,where most of the regions are typical of the northwest cold and dry regions.It consumes a lot of energy in the future,so public buildings should pay great attention to energy conservation in building design.At the same time,in the existing relevant domestic standards and research results,there is a lack of passive design and regional thinking of buildings,a lack of sorting and summarization of public buildings of the same type,and a lack of translation of theoretical principles into graphic languages to provide design guidance.Research,energy-saving design and architectural design are separated from each other,architectural design and traditional culture are not dependent,and traditional culture and energy-saving design are not compatible.At present,there is no clear guiding technical system for how to combine building space and overall shape with passive energy-saving design.Based on the opportunity to write "Guidelines for the Design of Passive Green Buildings in the Northwest Cold and Arid Regions(Gan Su)",the article investigated a large number of public buildings and traditional buildings on the spot.By analyzing the passive design strategy of typical public buildings,combined with the construction experience of traditional buildings,finally summarized the passive building design system suitable for public buildings in severe cold areas in Gan Su,which is used to guide public buildings to adopt effective passive energy-saving design methods in order to pass the building The design itself realizes energy-saving optimization.This research is mainly divided into four parts.The first part uses Climate Consultant software to simulate the climatic characteristics of Gan Su’s cold and cold regions,analyzes the software’s thermal comfort design strategy and passive design strategy,and summarizes 11 passive design strategies and 5 active design strategies applicable to Gan Su’s severe cold and cold public buildings.The second part is based on the passive design strategy summarized by the software,to analyze the passive design strategy of public buildings in the cold and cold areas of Gan Su,as well as the organization,spatial model and passive design strategy of traditional houses.The third part demonstrates the internal relationship between the passive strategy of traditional architecture and public architecture from the perspective of topology.Combined with the actual investigation of thermal comfort data to verify the effectiveness of the passive strategy,it summarizes the common passive space combination methods and design strategies suitable for public buildings in severe cold regions in Gan Su.The fourth part takes the summarized passive design strategy system as a reference,selects a typical area,and completes a new set of architectural design schemes,which provides a certain theoretical basis and design guidance for the passive design practice of public buildings in the cold and cold regions of Gan Su,my country.In summary,based on the principle of green passive design priority,the local green design strategy in severe cold areas in Gan Su is proposed to reduce the heating and cooling energy consumption of local buildings,improve the indoor thermal comfort environment,and develop passive technical guidelines for public buildings in Gan Su.Provide some help in green research and development.
