Calculate Energy Use Intensity (EUI)



Formula

The formula to calculate the Energy Use Intensity (EUI) is:

\[ EUI = \frac{TE}{TFLA} \]

Where:

Example

Let's say the total annual energy consumption (\( TE \)) is 5000 GJ and the total floor area (\( TFLA \)) is 2000 ft². Using the formula:

\[ EUI = \frac{5000}{2000} = 2.5 \text{ GJ/ft²} \]

So, the Energy Use Intensity (\( EUI \)) is 2.5 GJ/ft².

What is EUI?

Energy Use Intensity (EUI) is a measure of the total energy per unit of area that a building consumes on an annual basis. The energy is typically measured in units of gigajoules (GJ) or kBtu. The area units are most often square feet or square meters. EUI is an important metric for assessing the energy efficiency of buildings.

Energy Use Intensity Formula

Definition: Energy Use Intensity (EUI) is a measure of a building's energy efficiency, expressed as energy consumption per unit area.

Formula: \( \text{EUI} = \frac{\text{Total Energy Consumption}}{\text{Total Floor Area}} \)

Example: \( \text{EUI} = \frac{50000}{1000} \)

How to Calculate Energy Intensity

Definition: Energy intensity is the amount of energy consumed per unit of output or activity.

Formula: \( \text{Energy Intensity} = \frac{\text{Energy Consumption}}{\text{Output}} \)

Example: \( \text{Energy Intensity} = \frac{20000}{500} \)

Equation Useful Energy Intensity

Definition: Useful energy intensity measures the useful energy consumed per unit of output.

Formula: \( \text{Useful Energy Intensity} = \frac{\text{Useful Energy Consumption}}{\text{Output}} \)

Example: \( \text{Useful Energy Intensity} = \frac{15000}{500} \)

Intensity Formula in Terms of Energy

Definition: This formula calculates intensity in terms of energy.

Formula: \( I = \frac{P}{A} \)

Example: \( I = \frac{100}{20} \)

How to Calculate Electric Intensity

Definition: Electric intensity is the electric field strength at a point in space.

Formula: \( E = \frac{F}{q} \)

Example: \( E = \frac{10}{2} \)

How to Calculate Intensity

Definition: Intensity is the power transferred per unit area.

Formula: \( I = \frac{P}{A} \)

Example: \( I = \frac{50}{10} \)
