Refurbishing commercial buildings for higher energy efficiency
We invest significantly in refurbishing office premises
and shopping malls each year regardless of their age to
optimize their energy efficiency with the latest proven
technologies. The following table covering International
Commerce Centre, Sun Hung Kai Centre, Mikiki and
Landmark North details our consistent efforts to make
buildings greener.

Management
- Implement energy management
systems such as those to ISO 50001
standard
- Introduce energy efficiency guidelines

Collaboration with occupants
to change behaviour
- Encourage tenants to increase indoor
air temperature
- Encourage occupants to switch off
unnecessary lighting
- Provide free energy audits to tenants
to raise awareness

Lifts
- Operate passenger lifts
selectively during off-peak
hours
- Apply zoning controls for
new lifts
- Carry out routine
maintenance
- Upgrade chiller or chiller water pumps
that use more energy efficiency
technology
- Monitor chiller plant performance closely
via building management system and
analyze data to drive improvement
- Adjust chiller water temperature to
balance performance with energy
efficiency
- Maintain and repair chiller plant facilities
regularly for better performance
- Increase efficiency of air handling units
(e.g. filters with lower air flow resistance)
- Install occupancy sensors to better
anticipate energy demand
