Conducting a DIY energy audit is a fantastic way to identify where your home is using energy—and where you might be wasting it. By following a few simple steps, you can uncover opportunities to save energy, cut costs, and contribute to a more sustainable environment. Here are three practical examples of steps to perform a DIY energy audit.
Understanding how your lighting affects your energy consumption is a crucial part of any energy audit. In this example, we’ll focus on evaluating the efficiency of your home lighting.
First, gather a list of all the light fixtures in your home. Include everything from ceiling lights to table lamps. Next, check the wattage of each bulb. If you still have incandescent bulbs, consider swapping them out for energy-efficient LED bulbs. Not only do LEDs use significantly less energy, but they also last much longer.
Walk through your home in the evening and take note of which rooms feel over-lit or under-lit. This can help you assess if you need to adjust your lighting setup. For instance, if your living room has multiple lamps, you might consolidate to one or two brighter fixtures to reduce energy usage while still providing adequate light.
For an added layer of energy savings, consider installing dimmer switches or motion sensors in rooms that are frequently used. This will allow you to customize the lighting level based on your needs and reduce energy waste when rooms are unoccupied.
Your heating, ventilation, and air conditioning (HVAC) system is a significant energy consumer in your home. Regularly inspecting it can help you maximize efficiency.
Start by checking the air filters. Dirty filters can restrict airflow and force your HVAC system to work harder, consuming more energy. Depending on your system, you may need to replace or clean the filters every 1-3 months. Take this opportunity to familiarize yourself with your HVAC system’s maintenance requirements by reading the user manual or searching online.
Next, inspect the ductwork for any visible leaks. Utilize duct tape or mastic sealant to seal any gaps you find. If you’re comfortable doing so, you can also check your attic or basement for insulation around ducts, which can help maintain temperature throughout your home.
Lastly, consider setting your thermostat to a more energy-efficient setting. The Department of Energy recommends setting it to 68°F in winter and 78°F in summer for optimal savings.
Large appliances are often the biggest energy consumers in our homes. Performing an audit of your appliances can reveal opportunities for savings.
Begin by listing all major appliances such as your refrigerator, washer, dryer, and dishwasher. Check the energy labels to see how much energy each appliance typically consumes. If you notice any appliances that are older or less efficient, consider upgrading to ENERGY STAR-rated models, which are designed to use less energy.
Pay attention to how and when you use your appliances. For example, running your dishwasher only when it’s full and using the air-dry setting instead of the heat-dry option can lead to substantial energy savings. Similarly, washing clothes in cold water and air drying them can drastically reduce energy costs.
Lastly, consider using a smart power strip for appliances that are frequently left plugged in, as they can draw energy even when not in use.
By following these examples of steps to perform a DIY energy audit, you’ll not only save money on your energy bills but also contribute positively to the environment. Happy auditing!
