Cooling and Heating Load Calculator :

  • This calculator provides a simple method to estimate cooling and heating load.

  • Load refers to the heating or cooling demand of a building.
  • Capacity indicates how much heating or cooling an HVAC system can supply.

  • The cooling load is the amount of heat that must be removed to maintain comfort.

Heating Load :

  • The heating load is the amount of heat required to maintain a comfortable temperature.

Formula :

  • Square Feet Load = Square Feet × 25
  • Total Members Load = Members × 500 + 100
  • Total Windows Load = Windows × 1000
  • Total Doors Load = Doors × 1000
  • BTU = Sum of all above values
