Note:

• Lighting & Fan Loads: Calculated at 13 W/sq.m of all built-up floors.
• General Power Sockets: Sized at 55 W/sq.m for general-use power requirements.
• Basement/Parking: Calculated at a reduced energy envelope of 3.23 W/sq.m.
• HVAC Power Draw: Calculated at 1.25 kW/TR (incorporating both high-side chillers and low-side condenser pumps/AHUs).
• Lifts: Standard municipal traction passenger lifts are rated at 15 kW per lift.
