PDF《Energy Conservation》

1999 at ATCX, which houses the Air Traffic Control Centre and Air Traffic Control Tower, we contemplated a few measures as part of our continuous efforts in energy conservation.The results are as follows: (a) Procurement of electronic ballasts to replace the electro-magnetic ballasts of all the fluorescent light tubes installed in ATCX was in progress.The replacement work was scheduled to be carried out in the first quarter of 2001.It is estimated that the replacement of electro-magnetic ballasts with electronic types will reduce energy consumption by about 30%.The annual energy cost saved by the use of electronic ballasts is estimated to be $60,000. (b) Suitable harmonic conditioners are now being identified for installation to the electricity supply system of the ATCX and the BATCX.The harmonic conditioners can help to improve the overall energy efficiency. 节省能源 Energy Conservation

13 (c) 有关在航管大楼的公用地方装置移动 探测器,以确保空调及灯光在房间空 置了一段时间后会自动关上的措施, 我们在成本效益方面进行了详细的研 究.由於该装置的成本高昂及预期使 用率低,此措施已暂时被搁置. 除了由民航处负责大厦管理的航管大楼 及备用大楼外,民航处亦已就其他位於金 钟政府合署、机场客运大楼及机场空运中 心的办公室,向有关管理当局表达我们对 节约能源的关注.我们曾向金钟政府合署 大厦管理处反映我们对「用电需求管理计 划」的支持.「用电需求管理计划」是一 项由中华电力有限公司、香港电灯有限公 司及政府共同推行的计划,目的在维持本 港有稳定充足电力供应的同时,促进善用 及节约能源.此计划包括一个向非住宅用 户提供部份安装成本回扣优惠的措施以鼓 励他们更换高效能照明及空调设备. ? 购买能源效益高的仪器 作为一个对环境负责任的机构及支持政 府对环境保护的承担,我们有义务依从中 央订定的环保采购指引.在可行的情况 下,我们会把环保要求,如高循环再造性 及高能源效益等条款,放在标书细则中. ? 维持耗电量的增长低於香港国际机场的 航空交通增长 2000年的客货运处理量分别达3,340万 人次及224万吨,较1999年上升了9.8%及13.3% .飞机升降数目亦增至181,900架次,相对1999年上升了8.7%.虽然航空交 通量有不少的增长,但是航管大楼2000年 的平均每日耗电量 (15869度) 却较去年下 降了0.3%.这个成果相信是归因於在2000 年实施了的多项省电措施及员工对节约能 源的重视.不过,机场空运中心2000年的 平均每日用电量增至586度,较1999年增 加了15%.这是由於两个原因:第一,技 术及策划部的电子工程组就新的卫星航空 交通管制系统加装了新的电脑设备;

第二,位於机场空运中心的办事处扩大了, 以应付电子工程组的扩充. (c) A detailed study on the cost effectiveness of installing automatic occupancy sensors at the common use areas of the ATCX to turn off lighting and air conditioning automatically when an area is not in use was carried out.However,in view of the high equipment cost and the expected low utilization rate of the measure, it was decided to put in abeyance this option. Apart fromATCX and BATCX of which the building management is under the purview of CAD, for other CAD offices in QGO, Passenger Terminal Building of HKIA and AFFC, our concern on energy conservation has been expressed to the relevant parties.We conveyed to the Building Management of QGO of our full support on the Demand Side Management Programme (DSMP) launched by the two power companies,CLP Power Hong Kong Ltd and Hongkong Electric Company Limited, and the Government, to promote energy efficiency and conservation while maintaining reliable and adequate electricity supply in Hong Kong.The programme encourages the installation of energy efficient lighting and air-conditioning equipment by rebating part of the installation costs. ?
