Enter the total energy consumption in kilowatt-hours (kWh) and the area in square feet into the calculator to determine the energy usage per square foot. This calculator helps in assessing the energy efficiency of a space.
kWh Per Square Foot Formula
The following formula is used to calculate the energy usage per square foot.
E_{sf} = {E}/{A}Variables:
- E_{sf} is the energy usage per square foot (kWh/ft²)
- E is the total energy consumption (kWh)
- A is the area in square feet (ft²)
To calculate the energy usage per square foot, divide the total energy consumption by the area in square feet.
What is kWh Per Square Foot?
kWh per square foot is a measure of energy efficiency. It indicates how much energy is used per unit area and is commonly used to assess the energy performance of buildings. A lower kWh per square foot value suggests better energy efficiency, meaning less energy is used to maintain comfort in the space.
How to Calculate kWh Per Square Foot?
The following steps outline how to calculate the kWh Per Square Foot.
- First, determine the total energy consumption (E) in kilowatt-hours (kWh).
- Next, determine the area (A) in square feet (ft²).
- Next, gather the formula from above = E_{sf} = E / A.
- Finally, calculate the Energy Usage Per Square Foot (E_{sf}) in kWh/ft².
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Total energy consumption (E) = 1200 kWh
Area (A) = 1500 ft²
