How to Perform a Basic Energy Audit
An energy audit compares your actual energy use against benchmarks to identify saving opportunities.
Key Metric: Energy Use Intensity (EUI)
EUI = Annual Energy / Square Footage
Residential Benchmarks
Most homes can reduce energy use by 15-30% through basic efficiency improvements.
Example Calculation
A 2,000 sq ft home using 10,800 kWh electricity and 500 therms gas annually at $0.15/kWh.
- 01Energy intensity: 10,800 / 2,000 = 5.4 kWh/sq ft
- 02Electricity cost: 10,800 * $0.15 = $1,620
- 03Gas cost: 500 * $1.50 = $750
- 04Total cost: $1,620 + $750 = $2,370
- 05Potential 20% savings: $2,370 * 0.20 = $474/year
