Ceiling Fans

A non-portable device designed for home use that is suspended from the ceiling for circulating air via the rotation of fan blades. Some ceiling fans also have an integral or attachable light kit.

Life Cycle Cost Savings

Ceiling fan products certifying for ENERGY STAR under the Version 4.0 specification will offer consumers a savings of more than 40 percent.  If all ceiling fans sold in the United States were ENERGY STAR certified, the energy cost savings would grow to nearly $900 million and nearly 18 billion pounds of greenhouse gas emissions would be prevented.

For most applications, energy-efficient ceiling fans have the lowest life-cycle cost. For example, EPA has estimated that an Energy Star-qualified ceiling fan can save a typical user $165 in energy costs over the life of the unit, while avoiding 216 pounds of greenhouse gas emissions each year.

An efficient product is cost effective when the energy costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Energy Star considers both upfront costs and lifetime energy cost savings when setting required efficiency levels. Federal purchasers can assume that Energy Star-qualified products are life-cycle cost effective. On its Purchasing & Procurement page, Energy Star offers MS-Excel-based calculators to estimate how much money and energy you can save purchasing ENERGY STAR ceiling fans.

The National Renewable Energy Laboratory used computer models to determine the energy-saving potential of ceiling fans, and found that raising the cooling setpoint by 4 degrees F (from 74 to 78 degrees) could reduce building energy costs by as much as 11%. Savings are greatest in the first 4 degrees of setpoint change.

Guiding Principles

Additional Guidance

Energy Star Version 4 specification for Residential Ceiling Fans and Ceiling Fan Light Kits becomes effective on June 15, 2018.  Products included within the V4 specification are:

  • Products that meet the definition of a Residential Ceiling Fan (i.e., Standard and Hugger) or LowMount High-Speed Small-Diameter Ceiling Fan as specified.
  • Products that meet the definition of a Ceiling Fan Light Kit as specified.

Products excluded from the V4 specification are:

 

  • High-Speed Small-Diameter ceiling fans that do not meet the definition of Low-Mount HSSD.
  • Large-Diameter ceiling fans, as defined in 10 CFR Part 430, Subpart B.
  • Very-Small-Diameter, Highly Decorative, and Belt-driven ceiling fans, per Section 1, are not covered by the definition of a Residential Ceiling Fan for ENERGY STAR certification.
  • CFLKs packaged with bulbs that have an ANSI-standard lamp shape and base type that have not been ENERGY STAR certified (e.g., A19 shape and E26 base).
  • CFLKs not packaged with a light source.

 

Smart ceiling fans have sensors that measure temperature and incrementally adjust the fan speed. They turn on and off automatically based on occupancy or predetermined temperatures.

In researching smart ceiling fans for GSA's Proving Ground, the National Renewable Energy Laboratory found that smart ceiling fans should be considered for open office space with:

  • Ceilings at least 9 feet high and interior/desk partitions less than 54 inches tall,
  • At least 2,000 cooling degree days and full daytime business hours,
  • No features, such as lighting or air conditioning, that will interfere with fan blades, and
  • Cooling setpoint lower than 75 degrees, and no prohibition against raising it.

The Energy Star Product Specification for Luminaires V2.0 took effect on June 1, 2016. The specification applies to Ceiling Fan light kits.

Note that lighting that is part of a ceiling fan does not have to meet low standby power requirements otherwise applicable to lighting.

 The ENERGY STAR Most Efficient program identifies the most efficient products among those that qualify for the ENERGY STAR in particular product categories. Product categories were selected and recognition criteria were established to ensure that products that receive this recognition demonstrate efficiency performance that is truly exceptional, inspirational, or leading edge. There are Most Efficient criteria for the following sizes: 52 inches and under, 53-55 inches, 56-60 inches, and over 61 inches.

Included products: Residential ceiling fans, standard ceiling fans, and hugger ceiling fans, as defined below, are eligible for ENERGY STAR® Most Efficient recognition in 2017.

Residential Ceiling Fan: A non-portable device designed for home use that is suspended from the ceiling for circulating air via the rotation of fan blades.

Standard Ceiling Fan: a low-speed small-diameter ceiling fan that is not a very-small-diameter ceiling fan, highly-decorative ceiling fan or belt-driven ceiling fan; for which the lowest point on fan blades is greater than 10 inches from the ceiling.

Hugger Ceiling Fan: a low-speed small-diameter ceiling fan that is not a very-small-diameter ceiling fan, highly-decorative ceiling fan or belt-driven ceiling fan; for which the lowest point on the fan blades is less than or equal to 10 inches from the ceiling.
