Active Energy Management Limited was appointed by Cathay Pacific Airways for the planning and delivery of enhanced efficiency in the recently constructed Air Cargo Terminal at HK International Airport

The project was also integrated with a post-occupancy evaluation of the company's other facilities with the intent to embed relevant 'retrofit' opportunities found elsewhere as 'Day One' features in the new facility as well as including prevailing best practice features.

The project encompassed the following broad steps:

  • Greening Review of Cathay City, Headland Hotel and CNAC/KA House in conjunction with the original project's architect, assessing scope for improvement in both passive building fabric design and all engineering services. Opportunities for enhancing thermal behaviour, lighting, lighting control, BMS and energy reporting, air conditioning (air handling, chiller plant and means of heat rejection), vertical transportation etc. were all assessed, together with reviewing scope for adding solar water heating and PV generation. Process assessment related mainly to training pool energy use as well as in flight simulator hydraulics and air conditioning.
  • Selection of relevant applicable and positive features from HK BEAM and LEED, without 'points scoring' gaming, with attention biased towards items considered capable of making significant meaningful and cost-effective improvement in the context of the functional nature of the building. (For example optimizing chilled water pipe velocity proved much more dollar-effective than 'light tube' daylighting.
  • Preparing design briefing requirements for mainstream architectural and E&M designers, incorporating environmentally and energy efficiency feature objectives, with budget vs impact priority.
  • Reviewing subsequent sketch design, detailed design, tender stage interviews and post-tender contractor submission reviews.
  • Some examples of elements included were:
    • Challenging prevailing statutory obligations for daylighting in the context of large floor-plates, making reference to feedback experience on managing perimeter glare and heat gain in existing facilities.
    • Ensuring lighting circuits were aligned with building facades to allow progressive penetration of daylight linking.
    • Including requirements for highest grade electric motors.
    • Reviewing automated cargo handling to maximise use of gravity material flow and energy recovery motor drives.
    • Provisions for scrap timber gasification (waste to energy) scheme with space allocations and electrical feed-in provisions. Site-specific efficiency assessment of alternative PV solutions.
    • Feed-in provisions and structural provisions for large scale post-construction PV installation.
    • Pioneering adoption of radiant chilled ceiling installation, including large scale pilot trial installation with environmental logging and condensation margin testing.
  • During construction stage, AEM provided enhanced Commissioning Management support to Cathay Pacific, independently validating the correct and optimised set-up of energy consuming plant.
  • Into-service 'tuning' of E&M systems to ensure maximised real life efficiency was being achieved, with support and guidance provided to the ultimate permanent operator of the facility to maintain future performance.
