Ceiling fan energy efficiency is one of the many important things to consider when you buy a fan for your home. When you hear that a ceiling fan is energy efficient, you know it saves you money on utility costs and helps promote a cleaner environment, but how do you compare the energy efficiency of ceiling fans to see which is the best model for your home?
The U.S. Environmental Protection Agency requires all ceiling fan manufacturers to provide you with energy and performance information. A label with this data is affixed to the fan or printed on the box, and will tell you what you need to know about ceiling fan energy efficiency, airflow, and electricity usage.
Decoding Ceiling Fan Energy Information
The EPA’s mandate that all ceiling fan manufacturers provide the same types of energy information make it relatively easy to understand and compare different fans. A few of the most important ceiling fan energy efficiency performance measurements are provided below.
The top section on the label will list the testing speed to show how fast the fan was running for the results provided. To ensure uniformity, manufacturers are only required to list the results for fans tested at the highest speed. Although many of them do not test at lower speeds to avoid the extra testing costs, comparing the energy efficiency of ceiling fans at their peak levels of performance is all you really need
The airflow of your ceiling fan is measured in cubic feet per minute or CFM. This measures the volume of air your ceiling fan is capable of moving when it’s running at high speed. Airflow is the most important measurement to pay attention to when comparing fans. The amount of CFM correlates to how much air you feel coming off the fan, so higher is always better. Getting the best air movement is the most effective way to lower air conditioner usage and costs, and it helps keep the planet green.
Another ceiling fan energy efficiency measurement is the electricity usage, which is measured in watts. This makes it easy to compare to a light bulb. Even powerful fans that use a relatively large amount of energy typically do not use more than 100 watts—making ceiling fans the most energy-saving way to keep you cool compared to the high energy and monetary costs of air conditioners.
Your ceiling fan’s efficiency is measured by dividing the CFMs by the total watts your fan uses. The result is the cubic feet per minute per watt. It’s important to note that this is a ratio between the two measurements, not a percentage, so the number may be higher than 100 depending on the size of the fan.
Remember that airflow (CFM) is the most important measurement of ceiling fan energy efficiency. When considering the best ceiling fan for your needs, keep in mind that fans with powerful motors can be run at a lower setting to reduce wattage and increase the life of the fan. Regardless of the way you operate your ceiling fan, the versatility and efficiency of fans are unmatched, keeping a room cool at the fraction of the price and footprint of an air conditioner.
These are, of course, just a few of the many things to consider as you begin your search for the perfect ceiling fan for your home.
