SAVING FROM AIR-CON
• Adjust public area temperature to 25-26℃
• Adjust AHU cool air temperature to 13-14℃
• Fix VAV thermostat to 23-25℃
• Modify chiller plant operating schedule (for
ice storage/melting)
• Modify chilled water distribution according
to actual tenant requirements
• Regular cleansing of AHU valves
• Re-fix door frame to keep doors shut or add
air curtain
17
SAVING FROM LIGHTING
• Review all public lighting, no. of tubes
and schedule
• Mechanical floors changed to two way
switch
• Parking lot lights from halogen to T5
tubes and relocating to proper location
