One of our ongoing pursuits is the exploration of the latest technologies suitable for local application. In the past years, EEO has successfully promoted the application of a number of advanced energy-efficient systems and technologies. Some of them have proved to be highly successful, gaining wide acceptance by the public and the trade.

Technologies identified for trial are typically tested in pilot installations. Electronic ballast was the first type of technology successfully introduced and promoted. T5 fluorescent lamp was another important successful case. Following the success of our pilot projects in 2001, the T5 technology has been increasingly adopted by the engineering profession attracting the interests from both the manufacturers and users. The rising market demand has further driven down product prices, making the technology even more accessible and attractive. It has become a norm for many major developers to specify the use of T5 tubes in new buildings.

Other energy-efficient systems which EEO has tested and published include:

• Digital Addressable Lighting Interface (DALI) control technology for lighting systems,
• induction lamps,
• variable speed drives for air-conditioning systems,
• energy optimisers for escalator motor drives,
• heat-pump water heaters,
• self-luminous EXIT signs,
• LED EXIT signs,
• solar window films, etc.
