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

  • Efficient home: 3-4 kWh/sq ft/year
  • Average home: 5-6 kWh/sq ft/year
  • Inefficient home: 7+ kWh/sq ft/year

    • Most homes can reduce energy use by 15-30% through basic efficiency improvements.

    Ejemplo Resuelto

    A 2,000 sq ft home using 10,800 kWh electricity and 500 therms gas annually at $0.15/kWh.

    1. Energy intensity: 10,800 / 2,000 = 5.4 kWh/sq ft
    2. Electricity cost: 10,800 * $0.15 = $1,620
    3. Gas cost: 500 * $1.50 = $750
    4. Total cost: $1,620 + $750 = $2,370
    5. Potential 20% savings: $2,370 * 0.20 = $474/year
