既有建筑绿色低碳改造空间能效提升与用能结构优化Ⅱ——模型与转化
Space energy efficiency improvement and structure optimization in green and low-carbon renovation of existing buildings Ⅱ:Models and transformations
摘要
Abstract
Spatial energy efficiency serves as a key synergistic indicator in the green and low-carbon renova-tion of existing buildings.To establish a complete"prototype-mechanism-model-transformation"system,two design models of intensive hierarchical space and discrete open-connected space applicable to green and low-carbon renovation of existing buildings were proposed.Two distinct implementation pathways for high-energy-efficiency space of encircled spatial climate gradient and distributed environmental airflow organization were delineated,respectively.Empirical analysis was conducted on model application through demonstration cases from the National Key R&D Program-Strategic Scientific and Technological Innovation Cooperation.Re-sults demonstrate that the renovated Asian Architectural Archive Center reduces cooling and heating energy consumption by 30%and 34%respectively.The renovated School of Design and Environment 1&3,National University of Singapore(SDE1&3)buildings achieve annual energy consumption of 55 kW·h/m2,equivalent to one-third of pre-retrofit levels,with 36%increased time compliance rate for workstation natural illuminance.Through technical pathway innovation and practical verification,it drives the high-quality transition from experience-driven to scientifically-regulated approaches in green and low-carbon renovation of existing buildings.关键词
