More about Performance and Efficiency:

Ceiling fan manufacturers are required by federal law to publish an EnergyGuide label for all models in a standardized format, including watts used, cubic feet of air moved per minute (CFM), a resulting CFM per watt efficiency value and an estimated annual cost to use the product. These values are “weighted averages” of high and low speed performance and are intended to represent typical use. They are based on results from a standardized test gathered in a controlled environment and are furnished to help consumers and specifiers compare products. Because the standardized test method and the EnergyGuide format has changed over the years (with significant impacts on resulting data), be sure to only compare information which has been published based on current test methods and EnergyGuide label format. Many websites continue to provide “high speed” performance data instead of the more current “weighted averages”, making for large discrepancies. Please contact our customer support team with questions about performance data.

It is also important to recognize that in a real world installation, there are a number of variables that can affect air movement patterns and volume, including ceiling height, down rod length, room size/layout, furnishings and airflow direction. It can be challenging to rely on the reported EnergyGuide information alone to determine how the airflow might feel in a given application. Nevertheless, our EnergyGuide data shows that all Modern Fan products perform at the upper range of fans on the market.

Furthermore, while DC motor fans are reaching new levels of efficiency, it’s important to remember that all ceiling fans (AC or DC motors) are inherently efficient and use very little electricity to begin with, especially when used to offset or reduce use of air conditioning.
