Elements |
'Best
in Class' practices that we have adopted or
committed to implement in our portfolio |
|
Sustainability in energy efficiency
|
Energy management
|
- A dedicated energy taskforce to plan and execute
energy saving plans and budgets, and include
energy conservation in the Company policy
|
|
Assessment by external bodies (e.g. Building
Environmental Assessment Method, BEAM)
|
- Life-cycle of both new and existing buildings
are assessed by recognised environmental schemes
|
|
Energy conservation practices within the Company
|
- Use of sensors or timers to switch-off lightings
|
|
Influencing tenants
|
- Distribute guidelines/advices to tenants on
energy saving practices
|
|
Sharing with industry
|
- Publish papers on successful cases and research
- Participate in relevant award schemes by the
government or institutions
|
|
Minimise direct emissions
|
- Devices or policy to minimise leakage of GHGs
such as refrigerants
- Policy to recover CO2
from fire extinguishers during servicing or
testing
|
|
Reduction in energy consumption
|
HVAC
|
- HVAC equipment separately scheduled based
on the different operating hours and functions
- Heat recovery from exhaust air to fresh air
e.g. thermal wheel
- Apply free cooling / hybrid mechanical ventilation/air-conditioning
systems where applicable
|
|
Tenant lighting - energy saving and lighting
control
|
- Use of more energy efficient lamps, electronic
ballasts and addressable lighting control
|
|
Operation of lifts and escalators
|
- Counter weight adjustment
- Provision of passenger sensors to slow down
or switch off escalators
- Double-decked shuttle lift
|
|
Operation of hot water system
|
- Use of heat pumps to generate hot water
|
|
Continued improvements in operational efficiencies
for HVAC
|
Operational data collection and storage for analysis
|
- Provide appropriate sensors / control points
to collect data for analysing the running conditions
and efficiencies of the HVAC system
|
|
Data analysis for energy efficiencies
|
- Data are analysed to produce information for
operational improvement
|
|
Chiller plant energy analysis
|
- Use software to analyse historical and manufacturer's
data to automatically benchmark chiller plant
efficiencies with actual operating points
|
|
Automatic fault detection and diagnosis
|
- Use software to analyse historical data to
automatically detect faults of VAV boxes and
AHU valves
