The Formula Explained

The Energy Performance Index (EPI) is calculated using the formula:

EPI = \(\frac{Annual Energy Consumption}{Building Area}\)

Glossary of Terms

Building Area: The total floor area of the building.
Annual Energy Consumption: The total energy consumed by the building annually in kilowatt-hours (kWh).
Energy Performance Index: A measure of energy efficiency calculated as annual energy consumption per square meter.

How It Works: A Step-by-Step Example

For a building with an area of 1000 sq meters and an annual energy consumption of 500,000 kWh, the EPI is calculated as follows:

EPI = 500,000 / 1000 = 500 kWh/sq meter

Frequently Asked Questions (FAQ)

What is the Energy Performance Index?

The EPI is a measure of how efficiently a building uses energy, calculated by dividing the annual energy consumption by the building area.

Why is EPI important?

EPI helps identify energy-saving opportunities and improve building sustainability.

How can I improve my building's EPI?

Consider implementing energy-efficient systems, improving insulation, and using renewable energy sources.
