Definition and Purpose of a Home Energy Audit
A home energy audit is a thorough assessment of a residential property’s energy consumption and efficiency. It involves a detailed inspection of various aspects of the home to identify areas that are contributing to energy inefficiency and increased utility bills.
The primary purpose of a home energy audit is to help homeowners understand how they can reduce energy consumption and save money in the long run.
How a Home Energy Audit Helps Identify Energy Efficiency Issues
During a home energy audit, a certified professional will conduct a comprehensive evaluation of the home’s insulation, heating and cooling systems, appliances, lighting, and overall structural integrity. Through various diagnostic tests and the use of specialised equipment, the auditor will measure energy usage, detect air leaks, assess insulation levels, evaluate ductwork efficiency, and identify potential areas for improvement.

The steps involved in conducting a home energy audit
Once the audit is scheduled and all necessary preparations are made, the certified energy auditor will arrive at your home to conduct the assessment. The steps involved in the audit process may include the following:
- Initial Walkthrough: The auditor will start by conducting a visual inspection of your home, both inside and outside. They will look for any signs of air leaks, inadequate insulation, or inefficient appliances.
- Diagnostic Testing: Using specialised equipment, the auditor will perform various diagnostic tests to measure energy usage, airflow, and insulation levels. These tests may include blower door tests, infrared thermography, and combustion safety assessments.
- Detailed Evaluation: Based on the findings from the visual inspection and diagnostic tests, the auditor will compile a detailed evaluation of your home’s energy efficiency. They will identify areas that need improvement and provide recommendations for energy-saving measures.
- Audit Report: After completing the assessment, the auditor will prepare a comprehensive audit report. This report will outline the specific recommendations for improving energy efficiency, including estimated costs and potential savings.
- Explaining Recommendations: The auditor will review the findings and recommendations with you, explaining the benefits of each suggestion and answering any questions you may have. This is an opportunity for you to gain a deeper understanding of your home’s energy usage and the potential impact of implementing the recommended measures.
It’s important to note that a home energy audit is a non-invasive process that focuses on identifying energy efficiency issues. The auditor will not perform any repairs or installations during the audit. However, they may provide information on available rebates, incentives, and resources that can help you implement the recommended improvements.
Assessing Heating, Cooling, and Ventilation Systems
The energy auditor will also evaluate your home’s heating, cooling, and ventilation systems to determine their efficiency and identify potential areas for improvement. Some of the key components assessed in this part of the audit include:
- Heating and Cooling Equipment: The auditor will inspect your furnace, boiler, heat pump, or air conditioning units to assess their age, condition, and efficiency ratings. They will check for any signs of malfunction or inefficiency that could be contributing to high energy usage. The auditor may also recommend upgrading to Energy Star-certified equipment for greater energy savings.
- Thermostat Programming: The auditor will review your thermostat settings and programming to ensure they are optimised for energy efficiency. They may provide recommendations for adjusting temperature settings and utilising setback or programmable thermostats to maximise comfort and minimise energy consumption.
- Ventilation Systems: Proper ventilation is essential for maintaining a healthy indoor environment. The auditor will assess your home’s ventilation systems, such as exhaust fans and whole-house ventilation systems, to ensure they are functioning effectively and providing adequate fresh air exchange without excessive energy waste.
By evaluating insulation, air sealing, heating, cooling, and ventilation systems, a free home energy audit provides a comprehensive assessment of your home’s energy efficiency.
