HVAC LOAD CALCULATION FOR ENERGY SIMULATION IN BUILDING

ENERGY SIMULATION

1. HVAC Load Calculation Case Study: Energy Efficient Office Building

2. Building Overview • Office building, 10,000 m², warm-humid climate • Mixed-use zones: office, meeting rooms, lobby

3. Climate & Design Days • Summer: 35°C DB, 27°C WB • Winter: 7°C DB

4. Heat Gains • Internal: lighting, equipment, people • External: solar gains, conduction, infiltration

5. Results • Peak cooling load: 950 kW (July 15, 3 PM) • Peak heating load: 450 kW (Jan 10, 7 AM)
