Each home is unique, and the highest impact (financial and environmental) projects will vary by specifics of the home, appliances, and energy mix of your home and the local grid. Zwell’s home energy audit accounts for these factors to present projects that will save you the most money and reduce the most emissions.

Absolutely, we want as many people to learn how their home is impacting the environment and the steps they can take to reduce their carbon footprint. In fact, we’d love it if you shared your results with your friends and family, and together, we want to reduce the carbon emissions from one million homes by 2030.

Most people are able to answer all of the questions from the comfort of their couch in less than 5 minutes.

We have an extensive database of local grid information (including costs and energy generation), weather, solar insolation, groundwater temperatures and the energy demands of common household appliances. Based on the specific details of your home and location, we’ll calculate the carbon footprint of your current household systems and compare that to other options.

If there are potential CO2 and/or energy cost savings, we’ll list out how your carbon footprint or wallet could benefit by making a change! A home score, based on your unique situation, will indicate how close your home is to Net Zero and where it sits relative to other homes in your area. We share the specific CO2 totals of each appliance and estimate energy costs, so you can make an informed choice about your key household systems. Let’s get to Net Zero together!

You’ll be asked between 25 and 30 questions about your home. Most people know the answer to these questions off the top of their head or know how to find the answer. Examples of some of the questions include the year of your home, square footage, type of windows, appliances, etc.

The audit evaluates the most impactful components of a typical home by asking simple, easy-to-answer questions. Some general assumptions are required to make an energy use estimate for homes without knowing all of the specific complexities that may be hard to determine without a thorough inspection from a professional auditor. Estimates should be accurate for a typical home matching the answers provided, but unique conditions or qualities of the actual home beyond those answers may affect the reliability of that inference.
The score is meant to give a useful but approximate estimate without the need for difficult-to-obtain information. But if a precise level of accuracy is required, you may prefer to seek out a professional home energy auditor who can perform an in-home inspection and measurement.

No, a professional home energy audit performed by a qualified building performance professional can provide you with more precise information to make decisions about the most important home energy improvements. A home energy auditor will often use specialized equipment like thermal imaging cameras, blower door tests and other health and safety testing devices to provide you with a comprehensive and as accurate an audit as possible without doing invasive work in your home. Zwell’s DIY Home Energy audit is designed to educate and inform

We hope you will join the fight to reduce your carbon footprint and begin working on the recommended home energy improvements found in your audit and sharing your audit with your friends.
