Energy Audits

This weeks blog is about energy audits. I am not going to bore you with the formulas used to calculate how your kilowatts used is billed by the electrical company. I am going to excite you to explain how to save money on your electric bill and certain ideas to keep a few pennies in your pocket. So lets begin.

On a recent inspection in Webster Florida we had a client asking about how to lower the electric bill. The first way is to check the insulation in your attic as heat loss and cold air will be a big factor. But she went on and stated that the insulation was not the problem. What she was referring to was that from one year ago til that day she knew she used less electric as certain appliances and devices weren’t being energized but got the same bill. This is what brought about this blog and how we assisted her to find out what was going on in the home.

There are several types of ways to perform an energy audit. You have the blower door type, you can have assessment from the electrical company to analayize your electric bill then you have what we did. We did an assessment of her kilowatts used in the past 12 months. They usage was about the same per month. However, our client insisted that certain devices and appliances were not being used as she was traveling and turned off certain ones. This is what really brought “the raised eyebrow” If you are being billed a similar amount but using less electric yes the bill should be lower. So here is what we did.

First thing we did was to make sure that the panel box had no double taps. Maybe a neighbor had tapped into their electric box. (Could happen since they are on the exterior.) Then we turned on the appliances. The dishwasher, heat-pump, let hot water in the shower run for 20 minutes so the elements on the new hot-water heater were energized and the well pump was pumping water.  We turned on the oven and stove to assimilate we were cooking. (we did make coffee)  Then had all the lights on with ceiling fans going. And finally lowered the temperatures on the refrigerator and chest freezer to engage the compressors to turn on. Now keep in mind we did check the windows to make sure there was no heat loss. The windows were energy efficient and installed correctly. We even used an infrared camera to determine if there was any difference in temperatures. And for the most part they were fine. So, what is causing this issue.

As the appliances were in full energized mode we went to each one and checked electrical connections, insulation, and checked any electrical components. So first we checked the hot-water tank. That was performing perfectly. Then went down the list of the above mentioned appliances. And here is where it got interesting.

When we checked the loads and amps being used we found 3 aging appliances. We found that the chess freezer was over 12 years old. The gasket on the door was in its bonus life. This could affect the appliance to work more as it is loosing cold air. Then moving forward we checked the fans, the heat-pump and the oven. All working perfectly. So as we are nearing the end of the audit the last appliance we tested was the well pump, faucets and hose bibs. And here is where we found the culprit making the electrical bill high. The hose bibs on the side of the home were dripping. Just enough for the well pump to engage. Then checking the load on the well pump we found that the motor was engaging high amperage. To the point that the breaker did not trip as it was an incorrect breaker installed. The wingdings in the motor were winding faster and drawing more amperage then recommended. And with the incorrect breaker the breaker did not trip. And this would make the electric bill high.

So, in closing we found that that freezer gasket needed to be replaced as this could allow cold air to escape and which would engage the compressor to come on more then it should. The hose bibs were leaking enough for the well pump to engage and the well pump motor using more amperage then it should. Now keep in mind the home owners were traveling so alot of the devices were not energized but the major components were being worked more and defective. This audit assisted the home owner to know how to get the correct repairs and safety devices replaced.
