Benefits of Conducting a Home Energy Audit:
A home energy audit identifies areas where your home is wasting energy and recommends improvements that can result in cost savings, improved comfort, and a reduced environmental impact. There are several companies that offer home energy audit services, with prices ranging from around $150 to $500. Energy audits for commercial buildings are more complex and expensive, typically costing several thousand to tens of thousands of dollar
A home energy audit can identify areas where your home is wasting energy and recommend improvements that can result in lower energy bills. By identifying areas where heat or cool air is escaping, a home energy audit can help improve the comfort of your home. Reducing energy consumption in your home can help reduce your carbon footprint and contribute to a more sustainable future. A home that is energy-efficient and has lower utility bills may be more attractive to potential buyers and have a higher resale value.
Commercial buildings have more complex heating, cooling, and lighting systems than homes, which requires specialized equipment and expertise to analyze. The cost of an energy audit for a commercial building is typically much higher than a home energy audit due to the larger scale and complexity of the building. The cost can range from several thousand to tens of thousands of dollars depending on the size and complexity of the building.
Below is a video where you can tag along during a home energy audit. One interesting reveal here is that the worst energy loss in this home is not through the newer windows, but around them. A proper seal around the windows was never done.
Conducting Your Own Energy Audit
While professional energy assessment provides the most complete picture of your home's energy use, a diligent self-assessment can help pinpoint problem areas and prioritize your energy efficiency upgrades. The guide from the DOE is posted here. Their video is below.
