Research On Integration And Optimization Of General Pubic Architectural Design Guided By Passive Ultra-low Energy Building System

China's urbanization process has gradually transitioned to a new era of pursuing high-quality and sustainable development.General public buildings distributed in urban and rural environments are places to accommodate the demand of social activities.Based on their extensive distribution and massive construction,the social,environmental and economic impacts caused by energy consumption problems cannot be ignored.Based on the passive design,the passive ultra-low-energy building system is an important way to realize the sustainable development of buildings.In this context,this paper focuses on the basic issues of architectural design.Under the guidance of passive ultra-low energy consumption,general public building design is taken as the research object to analyze the relevant factors affecting architectural design.Starting from the connection between buildings and environmental energy,the paper explores the principles,methods and strategies of integration and optimization in architectural design.The article is mainly divided into five chapters: Chapter 1 clarifies the research background and problems,comprehensively analyses the research status at home and abroad,and constructs the research framework;Chapter 2 combs the concepts of building and environmental energy,passive ultra-low energy consumption building system and general public building;Chapter 3 combs environmental impact factors,architectural design elements and physical performance control elements.The fourth chapter systematically discusses the objectives,principles and methods of integrating and optimizing the design of controlled buildings,and puts forward operable integrated and optimizing strategies at four levels: site layout strategy,building shape design,building interface design and cavity space design.The fifth chapter is an empirical study,taking the architectural design of FIVEWIN Science and Technology Museum in Zhengzhou as the carrier,and making a comprehensive analysis.Based on the analysis,the integration optimization of architectural design is discussed from four aspects: site layout,shape design,interface optimization and spatial organization,and verified by simulation optimization.Through the integration and optimization of architectural design,we can createthe basic conditions for achieving the goal of passive ultra-low energy consumption,reduce the dependence on unnecessary technologies and measures and economic investment,promote the design decision-making to get rid of subjective randomness,improve the efficiency of design and decision-making process,and help to enhance and refine the research of passive ultra-low energy consumption buildings.
