Ceiling Fan
Ceiling fans with the Energy Star certification are 60% more efficient and use improved motors and blade designs. They typically have an integrated, energy-efficient LED light source. To meet the Energy Star standard, ceiling fans have to move 1,250 cubic feet per minute (cfm) 3,000 cfm, and 5,000 cfm on low, medium, and high speed, while using electric power of less than 155 W / cfm, 100 W / cfm, and 75 W / cfm, respectively.
Look at the Energy Star Most Efficient list for the current year. The most efficient ceiling fan on the list for 2017 is six times more efficient than the minimum Energy Star standard. It uses only 2 Watts on low speed, and with an LED light that only uses 6 Watts. This is amazingly efficient equipment, when you consider that older ceiling fans will often use 50 to 75 Watts, even at low speed. Some models have variable speeds, up to 6 speeds in forward and reverse, and allow dimming of the LED light.
A ceiling fan helps distribute warm and cool air in your living space, making the space more comfortable with less need to use energy for heating and cooling. If your house benefits from having a ceiling fan on for many hours in winter and/or summer, you can save additional energy on its operation by choosing a very efficient fan, and get an efficient and long-lasting LED light for the space at the same time.
Energy Star is a U.S Environmental Protection Agency (EPA) voluntary program created in 1992 to help homeowners and businesses save money and protect our climate. The Energy Star Label is now found on all major appliances, office equipment, lighting, home electronics, new homes, commercial and industrial buildings. Since its introduction it has helped save more than $300 billion in utility bills, and reduced greenhouse emissions by more than 2.4 billion metric tonnes.
