It is important to calculate heat load because it will help in keeping cost efficient and effective energy use. Depending on how much heat load you have, you need to identify the best option for your home, hostel or business needs.

By multiplying the specific heat of air (cp) by the density of air (rho) by the air flow (q) and the temperature differential, the sensible cooling load (hs) is derived. The sensible cooling load is divided by the overall cooling load to get the SHR.

Simply plug in the following formula to calculate the anticipated HVAC load for a house with 2,500 square feet, 12 windows, and 3 external doors occupied by 4 people: Base BTU = 2,500 x 25 = 62,500 4 individuals multiplied by 400 equals 1,600. 12 windows multiplied by 1,000 equals 12,000 dollars.
