【摘要】 以国家绿色三星项目——东莞生态园管委会办公楼设计为例,通过建筑环境计算机仿真与能耗实测对比,定性、定量分析与对比了办公建筑被动节能技术(包括朝向选择、自遮阳体系、自然采光、通风的利用等)及主动节能技术(包括水源热泵空调系统的运行、水资源的循环利用等)对岭南办公建筑生态性的影响,在计算机模拟与数据分析比较的基础上提出了优先使用低技术高效能的被动节能技术手段,并结合环境条件辅助使用适宜主动节能技术,以提高岭南地区办公建筑生态性、降低使用能耗的策略.更多还原

【Abstract】 Based on a national three-star greening project,namely the project of office hall design for the administrative committee of Dongguan Eco Park,a series of computer simulations and energy consumption measurements are carried out to analyze and compare the effects of several passive and active energy-saving techniques on the eco performance of office buildings in the South of the Five Ridges. The passive energy-saving techniques include the orientation optimization as well as the utilization of sunshading,natural lighting and ventilation,and the active energy-saving techniques include water recycling and air conditioning supported by water source heat pump. Then,a priority of the aforementioned passive techniques with less technological demand but greater efficiency,as well as an auxiliary use of the active energy-saving techniques to meet the requirements in particular conditions,is suggested,which helps to improve the eco performance and reduce the energy consumption of office buildings.更多还原
