Introduction to EUI Calculation Formula
The Energy Use Intensity (EUI) Calculator is a simple formula that calculates the energy used per square foot of a building over a period of time. The formula is:
EUI (kBtu/sq. ft. yr.) = Total Energy Consumption (kBtu) / Total Gross Floor Area (sq. ft.) / Number of Days in the Year
It may sound complicated, but don’t worry! We’ll break it down for you.

FAQs on EUI Calculator and EUI Calculations
Do you have some burning questions about Energy Use Intensity (EUI) Calculator and EUI Calculations? We’ve got answers! Check out the FAQs below:
- What is EUI? EUI stands for Energy Use Intensity, which is a formula that calculates the energy used per square foot of a building over a period of time.
- Why is EUI important? EUI is important because it helps building owners and managers identify opportunities to save energy and reduce costs.
- What is a good EUI score? A good EUI score depends on the type of building and its location. Generally, a lower EUI is better.
- How can I improve my building’s EUI? You can improve your building’s EUI by making energy-efficient upgrades, such as replacing old lighting and HVAC systems.
- What data do I need to calculate EUI? You need to know your building’s total energy consumption and gross floor area.
- How often should I calculate my building’s EUI? You should calculate your building’s EUI on a yearly basis.
- Is EUI the same as energy efficiency? No, EUI is a metric for measuring energy use intensity, while energy efficiency is a broader concept that includes all measures to reduce energy consumption.
- Can EUI be negative? No, EUI cannot be negative because it is a measure of energy use intensity.
- What is the difference between EUI and Energy Star rating? EUI is a metric for measuring energy use intensity, while Energy Star rating is a certification program for energy-efficient buildings.
- Can I compare my building’s EUI to other buildings? Yes, you can compare your building’s EUI to similar buildings using benchmarking tools like Energy Star Portfolio Manager.
