When it comes to choosing and installing a ceiling fan in your home, you might be of the mind to add an energy efficient model. Searching for an energy star ceiling fan is a great way to find an efficient option on the market. But not all energy efficient ceiling fans are energy star rated. Below, we will go over the definitions associated with these types of fans, and what constitutes an energy efficient model, so read on.
Terms and Definitions
When dealing with ceiling fans, you will need to understand some terminology. A few of the industry terms include cubic feet of air per minute (cfm) and cubic feet of air per minute per Watt of energy (cfm/W). The first term, cfm, is an overall measurement of the amount of air a fan can push or circulate around a room. For example, if a fan is rated at 3000 cfm, it pushes 3000 cubic feet of air per minute. The second term, cfm/W, is a measurement of the efficiency of the fan. For example, if a fan is rated at 100 cfm/W, it will push 100 cubic feet of air per minute per Watt of energy.

The Emerson Midway Eco is an energy star rated ceiling fan with a whopping 336 cfm/W energy efficiency rating.
Energy Star Criteria
For a fan to achieve an energy star rating, there are a couple of criteria that need to be met. The first is related to the cfm of the fan at low, medium, and high speeds. At low, it must have a minimum of 1250 cfm; at medium, it must have a minimum of 3000 cfm; at high, it must have a minimum of 5000 cfm. The second stipulation is related to the efficiency, or cfm/W, of the fan. At low, it must have a minimum of 155 cfm/W; at medium, it must have a medium of 100 cfm/W; at high, it must have a minimum of 75 cfm/W.
The motor of an energy star rated residential ceiling fan must be warrantied for at least 30 years, with the other fan components warrantied for at least one year. The fan must also meet the energy star luminaires specifications if it has a light kit. And finally, the fan must provide an easy way to change speeds, with either an easily accessible pull chain or remote control.

What if a fan isn't energy star rated?
So if you find a fan that you like but it is not energy star rated, does that mean it isn't energy efficient? Not always. For some companies, submitting their ceiling fans for rating is cost prohibitive and takes a long time. Since the EPA regulates these ratings for just about every piece of technology out there, you can imagine the red tape that needs to be cut through to obtain such a rating. If a fan meets all of the requirements but isn't energy star rated, it is likely that the company is either waiting for the government agency to get around to rating their product, or they simply refuse to deal with them.
So just because a fan doesn't have the rating doesn't mean it isn't energy efficient. There are several fans on the market that don't have that tag but easily meet the criteria. Pay attention to the cfm, the cfm/W, and the warranties available. Those things will clue you into how energy efficient a specific ceiling fan is.
Hopefully this article will help you to see what constitutes an energy efficient ceiling fan. Remember to keep these things in mind when shopping for your next ceiling fan for your home or living space. Thanks for reading!
