How much electricity does a 5-Star BLDC Ceiling Fan save compared to a 75W Induction Fan?

A 5-Star BLDC ceiling fan consumes 28 Watts at top speed versus 75 Watts for a conventional non-star induction fan. Running 2 fans for 12 hours daily saves ~33.5 Units every month (over ₹250/month or ₹3,000/year at ₹7.50/unit).

Are Ceiling Fans subject to mandatory BEE Star Ratings in India?

Yes. Under BEE Schedule 18 / Notification S.O. 2004(E), mandatory star labeling for electric ceiling fans came into effect on January 1, 2023. All new ceiling fans must display a BEE Star Label.

Do BLDC ceiling fans consume standby power when turned off using remote control?

Yes. When turned off via remote control while the wall switch remains ON, the internal RF/IR receiver PCB draws ~0.5 Watts of standby power. Switching off at the wall socket completely eliminates standby draw.

What is Service Value in ceiling fan BEE star ratings?

Service Value is the ratio of Air Delivery (in cubic meters per minute, m³/min) to Power Input (in Watts). A higher Service Value indicates greater energy efficiency. BEE 5-Star BLDC fans achieve Service Values ≥ 6.0.

How Ceiling Fan Power Consumption is Calculated

Ceiling fan electricity consumption is governed by BEE Schedule 18 mandatory star ratings and Service Value (m³/min/W). 5-Star BLDC fans use smart electronic commutators to cut power consumption by over 60%.

Daily Active Energy (kWh) = (Power W × Operating Hours × Fan Count) ÷ 1,000

Daily Standby Energy (kWh) = (0.5W Standby × Non-Operating Hours × Fan Count) ÷ 1,000

Worked Example (2 Atomberg 28W BLDC Fans): 12h/day = 0.684 kWh/day $\rightarrow$ 20.52 Units/month (₹153.90/month @ ₹7.50/unit) vs ₹405.00/month for 75W Induction (Saves ₹251.10/month or ₹3,013.20/year!)
