Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

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.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
