上海某商务楼建筑能源审计及节能潜力分析

Building Energy Audit and Energy-saving Potential Analysis for a Business Building in Shanghai

建筑能源审计和设备节能潜力评估是建筑节能开展合同能源管理的必要技术措施。本文以某综合性商务楼为例,介绍了建筑能源审计的研究方法,包括计算建筑总能耗、单位建筑面积能耗、不同功能区单位建筑面积用电量和空调能耗指标等,经审计比较后得出该建筑用能较为合理的结论。而后,测试了空调冷水机组、冷冻水泵、冷却水泵等设备的运行状态,对空调系统设备和照明设备提出了节能改造方案,预估综合节能率约为7.1%,投资回收期为3 a。

It is a necessary technical measure for contract energy management of building energy conservation to audit building energy and assess energy-saving potential of equipment. In this paper, to take a comprehensive business building for example, the research method of building energy audit was introduced, including calculating total building energy consumption, energy consumption per building area, electricity consumption per building area at different functional zones and air-conditioning energy consumption indicators,etc. ,and therefore a relatively reasonable conclusion for building energy consumption through audit and comparison was achieved. Afterwards, the operating conditions of such equipment as water chilling units, chilled water pumps and cooling water pumps in air-conditioning system were tested, and energy-saving reconstruction plan for air-conditioning system equipment and lighting equipment was brought forward. The predicated comprehensive energy-saving rate was about 7.1% ,and the payback period was 3 years.
