武汉建设大厦节能改造及运行效果

Energy saving retrofit and operation performance of Office Building of Wuhan Urban and Rural Construction

结合该项目的改造实践,探讨了既有建筑在绿色改造过程中的设计理念及适宜技术。该项目低能耗运行的主要原因在于其有效的设计策略:1)通过对建筑功能的优化设计,减少空调区域面积并利用自然通风,大大降低了过渡季及夏季空调能耗;2)通过平面优化设计,有效减少了照明能耗;3)提高了围护结构的隔热与遮阳性能,在提升室内环境质量的同时降低能耗;4)通过空调系统的优化设计,提高了能源的利用效率。

Combined with the experiences of the project, discusses the design concept and appropriate technology of green retrofit for existing building. The energy efficient operation of the building mainly results from its effective design strategies： 1） Greatly reducing the energy consumption of air conditioning in transitional seasons and summer through optimal design for the building function such as reducing air conditioned area and actively using natural ventilation; 2） Effectively reducing the energy consumption of lighting through optimization design of plan; 3） Effectively improving the indoor thermal insulation and sunshade performances of building envelope, which improves the environmental quality as well as reduces the energy consumption during operation after optimal design of envelope; 4） Improving energy efficiency through optimal design of air conditioning.
