How to Calculate HVAC Load for Any Project
- Gather Building Information:
This includes the building's location, size, insulation, window types, and occupancy details.
- Calculate Heat Loss:
Heat Loss = U-Value × Area × Temperature Difference
This looks at building materials, surface area, and temperature differences.
- Calculate Heat Gain:
Heat Gain = Solar Heat Gain + Internal Heat Gain
Solar heat gain considers sunlight entering through windows, and internal heat gain accounts for heat from occupants, appliances, and lighting.
- Summarize Loads:
Total the heat loss and heat gain for the entire building.
- Select HVAC Equipment:
Based on these calculations, pick HVAC equipment (like air conditioners, heaters, etc.) that's appropriately sized to meet the building's needs.
