Energy Efficiency Auditing FAQs, answered by experts

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew.
