Home Energy Audit Guide (Identify Energy Waste in Your Home)
Part of our Energy Efficiency & Utility Savings Hub.
A home energy audit evaluates how efficiently a house uses electricity, heating, and cooling. Energy audits identify areas where energy is being wasted and recommend improvements that can reduce utility bills.
Homeowners can perform basic energy checks themselves, but professional energy audits provide detailed assessments using specialized diagnostic tools.
What a Home Energy Audit Evaluates
| Inspection Area | Purpose |
|---|---|
| Insulation Levels | Identify heat loss through walls and ceilings |
| Air Leaks | Locate drafts around doors and windows |
| HVAC Efficiency | Assess heating and cooling system performance |
| Appliance Energy Use | Evaluate electricity consumption |
| Lighting Efficiency | Determine opportunities to upgrade to LED lighting |
Professional Energy Audit Tools
Professional auditors use diagnostic tools that help identify hidden energy losses within a home.
- Blower door tests to measure air leakage
- Thermal imaging cameras to detect heat loss
- Duct leakage testing to evaluate HVAC efficiency
- Energy monitoring devices to measure electricity consumption
Benefits of Conducting an Energy Audit
- Lower monthly electricity bills
- Improved heating and cooling efficiency
- Better indoor comfort
- Reduced environmental impact
- Identification of high-impact upgrades
Common Energy Efficiency Improvements After an Audit
Energy audits typically recommend improvements that deliver the greatest efficiency gains.
- Upgrading attic insulation
- Sealing air leaks around windows and doors
- Installing smart thermostats
- Replacing inefficient appliances
- Installing LED lighting
Energy Audits and Solar Power
Many homeowners perform energy audits before installing solar panels. Improving energy efficiency first allows solar systems to be sized more accurately and reduces overall installation costs.
