1. What is Energy Use Intensity (EUI)?

Energy Use Intensity (EUI) measures how much energy a building uses relative to its size. It's calculated by dividing total energy consumption by the total floor area, giving us kWh per square meter (kWh/m²).

2. How Does the Calculator Work?

The calculator uses the EUI equation:

Where:

• \( E \) — Total energy consumption (kWh)
• \( A \) — Total floor area (m²)

Explanation: This simple calculation helps us understand how efficiently energy is being used in a building. Lower EUI values indicate better energy efficiency.

3. Importance of EUI Calculation

Details: Calculating EUI helps identify energy-efficient buildings, track energy performance over time, and compare different buildings' energy usage. It's an important metric for sustainability and environmental awareness.

4. Using the Calculator

Tips: Enter total energy consumption in kWh and total floor area in square meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a good EUI value?
A: Lower EUI values are better. Typical values range from 50-300 kWh/m²/year depending on building type and climate.

Q2: Why is EUI important for kids to learn?
A: Understanding EUI helps kids learn about energy conservation, sustainability, and how to be more environmentally responsible.

Q3: Can EUI be used for homes and schools?
A: Yes! EUI can be calculated for any building - homes, schools, offices, or any other type of structure.

Q4: How often should EUI be calculated?
A: EUI is typically calculated annually to track energy performance over time, but it can be calculated for any period.

Q5: What units are used for EUI?
A: EUI is most commonly expressed in kWh/m² (kilowatt-hours per square meter) for metric measurements.
