Get matched with top energy efficiency auditors in Murray, KY

Q: What is a good blower door test score?

• <div><p>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&rsquo;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. </p></div>

Q: How much energy can I expect a home wind turbine to generate?

• <div><p>Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home&rsquo;s needs. Accurate output estimates require a professional wind assessment and a review of your household&rsquo;s energy usage patterns.</p></div>

Q: What is the electrical load for a residential home?

• <div><p>There is no blanket figure for a residential home&rsquo;s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it&rsquo;s safe to assume 40 to 60 amps is the average electrical load of a residential home. </p><p> </p></div>

Q: What state has the highest utility bills?

• <div><p>Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.</p></div>

Q: Who does energy audits?

• <div><p>Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.</p></div>

"Wonderful, it was a very quick and easy process. Brian talked us through it and in no time we had a 3KW system mounted on a frame in the garden and the invertor installed in the basement. Brian talked us through working with our power company to get the system checked and approved and we now get credits from the power company for power we provide to the grid. In addition we are set up to get Solar Renewable Energy Credits (SRECs) payments for providing clean energy. We also got a free Energy Audit which helped locate some problems areas we were able to fix. The system has basically cut our energy costs in half. I have hesitation in recommending them to anyone interested in solar energy."
