摘要

自然通风作为降低建筑能耗的重要手段，近年来受到广泛关注。本研究以探索自然通风与建筑能耗之间的关联为核心，旨在为建筑设计提供科学依据以实现节能减排目标。研究选取典型气候区域的多栋建筑作为案例，通过现场监测、数值模拟及数据分析相结合的方法，系统评估了自然通风对建筑能耗的影响机制。研究结果表明，合理设计自然通风策略可显著减少空调和机械通风系统的使用频率，从而有效降低建筑运行能耗。创新点在于引入动态模拟技术，结合实时气象数据，建立了自然通风潜力与建筑能耗的量化模型，揭示了两者间的非线性关系。此外，研究还提出了一套适用于不同气候条件的自然通风优化设计方法，为实际工程应用提供了参考框架。最终结论显示，在适宜气候条件下，通过优化自然通风设计，建筑能耗可降低20%-30%，同时改善室内空气品质与热舒适性，为推动绿色建筑发展提供了重要支持。

ABSTRACT

Natural ventilation has garnered significant attention in recent years as a critical approach to reducing building energy consumption. This study focuses on exploring the relationship between natural ventilation and building energy consumption, aiming to provide scientific evidence for architectural design to achieve energy-saving and emission-reduction goals. Multiple buildings in typical climate zones were selected as case studies, and a systematic evaluation of the impact mechanisms of natural ventilation on building energy consumption was conducted using a combination of field monitoring, numerical simulation, and data analysis. The results indicate that a well-designed natural ventilation strategy can substantially decrease the usage frequency of air conditioning and mechanical ventilation systems, effectively reducing operational energy consumption in buildings. An innovation of this research lies in the introduction of dynamic simulation technology integrated with real-time meteorological data to establish a quantified model linking natural ventilation potential with building energy consumption, revealing the nonlinear relationship between the two. Furthermore, a set of optimization design methods for natural ventilation applicable to various climatic conditions was proposed, providing a reference fr amework for practical engineering applications. The final conclusion demonstrates that, under suitable climatic conditions, optimizing natural ventilation design can reduce building energy consumption by 20%-30%, while simultaneously improving indoor air quality and thermal comfort, offering crucial support for the advancement of green building development.
