What Are HVAC Load Calculations?

HVAC load calculations determine the heating and cooling requirements of a building. These calculations consider building size, insulation, occupancy, equipment, and climate.

Why They Matter

• Prevent over/undersizing of equipment
• Ensure energy efficiency
• Guarantee occupant comfort
• Meet building codes

Key Factors

Building Envelope: Walls, windows, doors, roof - each affects heat transfer.

Internal Heat Gains: People, lights, equipment generate heat.

Ventilation: Fresh air requirements affect HVAC load.

Conclusion

Proper HVAC load calculations are essential for building performance and efficiency. IEPM uses advanced software and ASHRAE standards for precise calculations.
