As a responsible corporate citizen, we believe that providing quality services is just one element in the total quality equation. Our services must also contribute to the quality of life for everyone in Hong Kong - a major factor in ensuring this quality of life is the need to conserve and sustain a green environment. The efficient use of energy makes a significant contribution in this direction, ensuring both the wiser use of the world's resources as well as generating less pollution in the production of energy.
At EMSD, an Energy Efficiency Office (EEO) was established in 1994, to provide the technical expertise and the drive for energy efficiency and conservation programmes. The Office works to issue codes of practice, such as Building Energy Codes, establish guidelines, and is actively involved in working groups and related committees in the efficient use and conservation of electricity. Additional initiatives range from energy management to database management, benchmarking, the exploration of advanced energy efficiency technologies, energy efficiency labelling scheme, to promoting wider use of new and renewable energy. Our successes in this direction will help to ensure a greener and brighter future for all of us in Hong Kong.
The Energy Efficiency Office also publishes a newsletter "EnergyWits" on energy efficiency and conservation. The latest issue of this newsletter (forty-first issue) [PDF format (6.86MB)] and all issues of the EnergyWits newsletter are available for viewing on-line.
