Dr. Ir Leonard Chow is the Member of the Task Force for Review 2006/2007 Energy Efficiency Registration Scheme for Buildings of EMSD

The reviews were conducted by EMSD in conjunction with dedicated Task Forces with participation from representative organizations in the building industry including professional institutes, trade organizations and the academia. The reviews were to ensure that the BEC and the Registration Scheme cope with technological advancement and prevailing building trade practice.

Review in 2006/2007

The review simplified the application forms, and offered registration to energy-audited buildings meeting good energy performance requirements. The review also identified the following amendments in the BEC:

• Lighting - the requirements on luminous efficacy and LPD are generally upgraded, EMSD's Voluntary Energy Efficiency Labelling Scheme for CFL and Electronic Ballasts are quoted as requisite requirements, a performance approach for LPD compliance is introduced to Atrium/Foyer & Vehicle Depot, the requirements on maximum allowable LPD are extended to Retails, Restaurant, & Vehicle Unloading Bay, minor deviation from compliance is allowed for a small quantity of lighting, the maximum allowable controlgear loss requirements are extended to outdoor lighting, and the performance approach on LPD requirement in a composite space is emphasized;
• AC - the COP requirements for various AC equipment are upgraded, and designers are requested to provide data on Part Load Values of AC equipment and motor power of fan coil units;
• Electrical - the maximum allowable copper loss requirements for exceedingly lengthy circuits are slightly relaxed, the motor efficiency requirements are upgraded, the requirement on power transfer devices is waived, and a performance requirement as an alternative to THD compliance is introduced;
• Lift & Escalator - the maximum allowable electrical power requirements are upgraded, with high speed fire service lifts or sky lobby shuttles serving a tall zone exempted from the maximum allowable electrical power requirements.

Incorporating these amendments, the 2007 edition of BEC are developed. Having had the 2007 edition, the 2005 edition could still be adopted in the interim. Installations with design commenced in October 2007 should follow the 2007 edition, and installations designed earlier than October 2007 could follow the 2005 edition. Installations designed even earlier and not complying with both of these editions could apply for good energy performance certification. Installations certified for BEC compliance could also apply for good energy performance certification.
