A ceiling fan is one of your major tools for achieving energy efficiency. When the blades run counterclockwise, they help move cool air around, creating a wind chill effect so that a room’s occupants feel cooler as perspiration on their skin evaporates. In the winter, the blades should be reversed so that they can push warm air from the furnace down from the ceiling to floor level. Either way, the fan allows you to cut back on energy use from your HVAC system.
But not all ceiling fans are created equal when it comes to energy efficiency. If you’re looking for greater energy efficiency through the use of your ceiling fans, then you may want to do a little research prior to choosing them.
What Makes an Efficient Ceiling Fan?
- Look for the Energy Star label.
Ceiling fans that are tested and rated by the government’s Energy Star program are the most efficient. Whenever possible, choose an Energy Star-labeled fan.
- Look for a fan with longer blades.
In general, a fan with longer blades will move more air (measured in cubic feet per minutes) than fans with shorter blades. The key is to move more air, but at a lower speed. You don’t want to be running the fan at high speed all the time or you will waste money on your utility bills.
- Compare the efficiency of fans by labels.
Labels should reveal the amount of air flow, how many watts the fan uses and the fan’s air flow efficiency (cubic feet per minute of air moved by 1 watt).
- Look at the ceiling fan lights’ efficiency as well.
Be sure to look at how efficient the lighting that comes with the fan is. Ceiling fan lights tend to get used a lot, so it’s important that you check for the most efficient ones.
Whichever fan you choose, keep the fan blades clean for greater efficiency. Dirty blades resist air flow.
