The formula to calculate the Energy Use Index (EUI) is:
\[ EUI = \frac{E}{A} \]
Where:
The Energy Use Index (EUI) is a benchmarking tool that measures the energy efficiency of a building by calculating the amount of energy used per square foot per year. It is expressed in units of energy per square foot per year and it’s used to compare the energy efficiency of different buildings or the same building over time. A lower EUI indicates better energy efficiency. It is a crucial component in energy management and sustainability strategies for commercial and residential properties.
Let's say the total energy consumed (E) is 500,000 kBtu, and the total floor area (A) is 50,000 ft². Using the formula:
\[ EUI = \frac{500,000}{50,000} = 10 \]
So, the Energy Use Index (EUI) is 10 kBtu/ft².
