我国绿色建筑常用节能技术后评估比较研究
POE research on common energy saving technology applied to green buildings in China
摘要：
根据后评估（POE）的方法，对我国不同气候区的11栋绿色建筑及示范建筑的实际能耗情况及节能技术进行了调研和分析研究，包括围护结构、暖通空调系统、生活热水系统及可再生能源系统等，对系统的设计参数、运行效果、实际能耗、室内环境质量和使用满意度进行了分析，总结了设计、运行中的常见问题和优化策略。研究发现，自然通风和自然采光等低成本被动式技术实际运行效果良好，值得重视和推广；人员的行为模式和使用模式对能耗影响较大，应成为节能运行管理中的要点；绿色办公建筑在引进建筑节能技术和应用可再生能源系统时，需考虑技术的经济性。在中国现有建设水平下，应发展低能耗、低投入成本、低空间成本、高运行效率的示范技术。
Abstract：
With post-occupancy evaluation (POE) method, investigates and analyses actual energy consumption and energy saving technology of eleven green buildings and demonstrating buildings in different climate zones in China, which covers building envelope, HVAC systems, domestic hot water systems and renewable energy systems. Analyses design parameters, operation performance, actual energy consumption, indoor environment quality and users’ degree of satisfaction. Sums up common questions and optimization strategies in design and operation. Finds that the passive techniques with low costs such as natural ventilation and daylighting have good operation effects, deserving attention and popularization. The behaviour mode and use pattern of occupants have a major influence on energy consumption, which should be deemed as key points in operation management. Economical efficiency should be considered when importing energy technology for buildings and applying renewable energy. The demonstrating technologies with lower energy consumption, investment costs and space costs and higher operation efficiency should be developed under exist constructions level in China.
