What is the heating and cooling load of a building?

Heating and cooling loads are the measure of energy needed to be added or removed from a space by the HVAC system to provide the desired level of comfort within a space. Right-sizing the HVAC system begins with an accurate understanding of the heating and cooling loads on a space.

What is the heat load per unit area?

In the Industry, the Heat Load per unit Area (btu/h/sqft) is a key parameter used as to determine a required cooling or heating capacity. It may be a usual practice for designers to consider other forms of Heat Loads by directly applying a higher Heat Load per unit Area (btu/h/sqft).

How do you calculate HVAC load for a building?

## Example HVAC Load Calculation

1

2,000 square feet x 25 (base value) = 50,000.

2

3 people x 300 = 900.

3

10 windows x 1,000 = 10,000.

4

2 exterior doors x 1,000 = 2,000.

5

50,000 + 900 + 10,000 + 2,000 = 62,900 BTU.
