Air-conditioning Systems
  • Consider using centralised type air-conditioning system rather than non-centralised 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 within an 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 minimise 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 using 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 the area is 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
  • Disconnect power source after using electrical equipment
