Abstract: The 1999 Policy Address presented by Mr. Tung Chi Wah, the HK SAR Chief Executive emphasized the importance to make Hong Kong a clean, comfortable and pleasant home. One of the outsets is to reduce the environmental burden by reducing overall energy consumption, pollution and waste, while at the same time, helping to preserve natural resources. An introduction and implementation of an appropriately developed and well planned Energy Management System in a commercial building by the facilities/energy manager of the management company would provide effective guidelines and procedures to enable the organization in short term: i) to achieve a cost and energy saving; ii) to improve business performance, efficiency and productivity; iii) to reduce the environmental impact; iv) to label the corporate and building with a "Green" and or "Energy Efficient" image and; v) to provide occupants with a clean, safe, health and comfort working environment. In long term, it is aiming to increase the public awareness and to motivate the other building occupants and tenants to participate in an energy management programme through the marketing technique of an Energy Management System. In Hong Kong, there has been always a perception that energy management is a technical issue rather than managerial issue, and is of low priority as compared with other business activities. Hence, most of the energy saving activities are undertaken by the technical department of an organization alone, without much support and commitment from top management. To improve this situation, the Energy Management Guide, General Information Report 12 that was prepared by the U.K. Building Research Energy Conservation Supply Unit (BRECSU) and provides effective managerial guidance to the management organization, has been adopted as the base for the development of an Energy Management System able to suit the local practice. In addition, software analytical tools have also been employed to increase the effectiveness of the Energy Management System developed. A case study on applying the Energy Management System developed has been carried out in a 70 storeys high rise office building in Hong Kong. The case study included a formal assessment of the Building Management aspects in Energy Management, and a site audit of the energy consumption for the building services installations, such as the lighting, air conditioning mechanical ventilation and potable water supply system, etc. of the building. In addition, a questionnaire survey was also carried out among the energy management team members in order to evaluate their awareness, and the effectiveness of the Energy Management System developed. The case study demonstrated that the EMS developed can help the building owner/management effectively raise staffs awareness in energy conservation, distribute the accountability and responsibility of Facilities/Energy Manager to responsible department, people and ultimately achieve a reduction in energy use and operating cost of the building.
