Air-conditioning Systems

• • Consider using centralized type air conditioning system rather than non-centralized type system
     if possible.
• • Consider using water cooled chillers instead of air cooled type for centralized system
• • Opt to use Grade 1 Energy Label for window-type and split-type air-conditioners
• • Maintaining the indoor temperature at 25.5 °C or at appropriate temperature range.
• • Regular maintenance of the air conditioning system to keep the system running in high efficiency.
• • Installation of solar films on windows to minimize the external heat gain to the premises.
• • Place “Energy Saving Alerts” labels in common areas in offices.

Lighting & Electrical Systems

• • Opt to use T5 fluorescent tubes with electronic ballasts instead of old type T8, T10 or T12 tubes
• • Opt to use halogen lamps for accent lighting application
• • Avoid using incandescent lamps
• • Switch to use LED lamps where appropriate
• • Switch to use LED EXIT Signs and Emergency Lights
• • Consider to use compact fluorescent lamps or LED type fluorescent lamps with Grade 1 Energy Label
• • Installation of occupancy detectors and digital timers in areas which are infrequently used. The
     devices can help controlling the switching of the lights when not occupied for a certain period of time.
• • Re-design of lighting zones so that the lights can be controlled in small groups such that partial lighting
     can be achieved.
• • Install those high reflectors for lighting fixtures such as aluminum and silver reflectors

Audio-visual Equipment

• • Use the equipment with higher ranks of Energy Label
• • Disconnect power source after using audio-visual equipment

Computers/Office Equipment

• • Disconnect power source after each use of equipment
• • Phase out CRT monitors
• • Ensure sleep mode or energy saving mode are enabled during operating hours

Miscellaneous

• • Disconnect power source after using electrical equipment
