A Professional Energy Audit, on the other hand, is conducted by trained professionals who use specialized tools and equipment to assess a home’s energy efficiency. These audits are more detailed and provide a comprehensive evaluation of the home’s energy usage, identifying specific areas for improvement.

An Online Energy Audit is a self-guided audit that can be completed online using software or tools provided by energy companies or government entities. This type of audit allows homeowners to input information about their home and energy usage to receive a basic assessment of energy efficiency. While online audits may not be as accurate as professional audits, they can still provide valuable insights and recommendations.

Components of a Home Energy Audit

A Home Energy Audit consists of several key components that help evaluate the energy efficiency of a home:

Utility Bill Analysis: The auditor will examine your utility bills to determine your energy consumption patterns and identify any irregularities or areas of high energy usage.
Thermographic Inspection: This involves using an infrared camera to detect heat loss or air leakage in the home by capturing images that show temperature variations. This helps identify areas where insulation or sealing may be insufficient.
Blower Door Test: A blower door is a powerful fan that is mounted in an exterior door frame to measure the airtightness of a home. By depressurizing the house and measuring the airflow, the auditor can identify air leaks and drafts.
Air Leakage Analysis: This involves a thorough examination of the home for any air leaks, using techniques such as smoke pencils or thermal imaging cameras. Identifying and sealing air leaks can significantly improve energy efficiency.
Insulation and Ventilation Inspection: The auditor will assess the insulation levels and quality throughout the home, including walls, ceilings, floors, and ductwork. Proper insulation helps maintain a consistent indoor temperature and reduces energy waste.
Appliance and Lighting Evaluation: The auditor will assess the energy efficiency of your appliances and lighting fixtures. This can involve checking for ENERGY STAR® ratings, analyzing wattage usage, and recommending more efficient options where necessary.
HVAC System Assessment: The auditor will evaluate your heating, ventilation, and air conditioning (HVAC) system, checking for proper sizing, efficiency, and maintenance. This helps identify any issues or inefficiencies that may be affecting energy usage.
Water Heating Assessment: The auditor will examine your water heating system, assessing its efficiency and insulation. They may also recommend water-saving measures, such as low-flow fixtures or insulation wraps for the water heater.

Common Findings in Home Energy Audits

During a Home Energy Audit, several common findings may be identified:

Inadequate Insulation: One common issue is insufficient insulation, which can lead to significant energy loss. A Home Energy Audit can help pinpoint areas where additional insulation is needed for maximum energy efficiency.
Air Leaks: Air leakage through gaps, cracks, or poorly sealed areas in the home can significantly impact energy efficiency. Auditors can identify these leaks and recommend sealing measures to prevent air infiltration.
Inefficient Appliances: Outdated or inefficient appliances can be a major source of energy waste. Identifying and replacing these appliances with more energy-efficient models can result in significant energy savings.
Old HVAC Systems: Aging heating and cooling systems may be less efficient and consume more energy. An audit can help identify the need for upgrading to newer, more energy-efficient HVAC systems that will save on energy costs.
Water Heater Inefficiency: Inefficient water heating systems can waste a significant amount of energy. Auditors can assess the efficiency of your water heater and provide recommendations on how to improve its energy performance.
