Introduction to HVAC Loading Calculator

Heating, ventilation, and air conditioning (HVAC) load calculation is the process of determining the heating and cooling requirements for a building or space. In this formula, HL represents the total HVAC load, Area is the area of the room, and CL is the cooling load per unit area. The result is expressed in specific units depending on the cooling load and area used (e.g., BTU/h, tons, etc.).

Parameter usage:

Example valid values:


Data validation

The room area should be greater than zero, and the cooling load should be a positive number indicating the cooling capacity per unit area.


This calculator helps estimate the heating, ventilation, and air conditioning (HVAC) load for various types of spaces based on the measured area and required cooling load. The result aids in designing and choosing appropriate HVAC systems for different types of buildings or rooms.
