既有建筑绿色低碳改造空间能效提升与用能结构优化Ⅰ——原型与机理
Space energy efficiency improvement and structure optimization in green and low-carbon renovation of existing buildings Ⅰ:Prototypes and mechanisms
摘要
Abstract
The green and low-carbon renovation of existing buildings is a key pathway to achieving"emission peak"and"carbon neutrality".To reveal the influence mechanisms of spatially synergistic effects based on heat transfer principles on energy efficiency improvement and energy structure optimization,a typological clas-sification of environmental regulation and heat transfer mechanism analysis were conducted.An association model between spatial prototypes and energy transfer was established.Two types of environmental regulation,isolated type and interactive type,were systematically analyzed.The mechanism correlation between heat transfer effects such as radiation,convection,conduction and evaporation,and the enhancement of spatial en-ergy efficiency was elucidated.Optimization mechanisms for indoor climate gradients and environmental air-flow organization in spatial renovation design were summarized.The results indicate that a hierarchical ther-mal resistance distribution significantly reduces building energy consumption,and an open airflow organiza-tion effectively enhances natural ventilation efficiency.The proposed two high-energy-efficiency architectural spatial prototypes of intensive hierarchical space and discrete open-connected space provide theoretical support for methodological research and practical exploration of green and low-carbon renovation of existing buildings.关键词
