The star rating (usually 1 to 5 stars) is a very simple and direct measure of a fan's Environmental Efficiency Ratio (EER). It tells the amount of air that the fan releases per unit of the power (in Watts) it uses, as determined by a body like the BEE
You meticulously spend hours researching energy-efficient appliances such as refrigerators, washing machines, and air conditioners.
You delve into their labels in detail and compare the annual consumption figures. What about the appliance that is practically working 24/7 in almost every room of your house, but you have not given it much attention?
The ceiling fan. Ordinary, non-rated fans are stealthy power hogs that can significantly increase your monthly electricity bill without your consent.
What is the solution? The BEE (Bureau of Energy Efficiency) Star Rating system. This frequently neglected guide is the turning point to drastically reduce the energy consumption of a fan.
Let’s look into star rating of ceiling fans together.
The star count on a ceiling fan isn't just flashy info; it shows exactly how well it saves power. Ratings usually go from one to five stars, decided by official groups tied to global standards, like India’s Bureau of Energy Efficiency (BEE) or similar agencies elsewhere.
The fan's Energy Efficiency Ratio (EER) basically decides its star rating. Putting it simply, this is the major reason why the fan is responsible for a lot less power consumption (expressed in Watts) when providing the same cooling or air delivery.
The one with 5 stars is the winner of energy efficiency, requiring the smallest amount of power to achieve the maximum air flow.
Keep in mind, efficiency rules don't last forever. Take BEE, they tweak their motor efficiency benchmarks every few years as tech gets better.
So a fan rated 5 stars back then could now pass as just 3 stars. That old rating? It may not hold up today. Look at the label’s expiry date before buying, so you get one that fits today’s tougher standards.
The main way to compare is by how many watts it takes for each bit of airflow measured in cubic meters per minute. Less power needed for more airflow means a higher star score.
Let’s get specific with the numbers. A typical ceiling fan that has not been rated or has a 1-star rating and uses a traditional induction motor is a significant power consumer, and its power consumption is usually between 75 and 80 Watts (W).
If a house has four or five fans that are on for the whole day, the power consumption resulting from this wattage will increase very fast.
On the other hand, a super-efficient 5-star rated fan is equipped with the latest technology to achieve the same result while consuming an unbelievably low power of only 28 to 35 Watts (W).
While the difference of about 40 to 50 watts per fan may seem insignificant, it is the main factor in the complete overhaul of your electricity bill.
The real reason for these big power cuts? It's down to the brushless DC motor.
Old-school fans run on AC electricity, which causes ongoing drag plus wear, wasting lots of power as heat while making a racket.
But BLDC models rely on strong magnets along with smart switching tech that changes the incoming AC current into smooth DC right inside the device. That shift brings three clear upsides:

Knowing the wattage difference between the two allows you to figure out the exact amount of money a 5-star fan could save you. You only need the old and new wattage of your fan, the hours of use per day, and the cost per unit of your utility (kWh).
The formula is very straightforward. It just calculates the daily savings in energy units:
Energy saved (kWh/day) = [(old wattage – new wattage) x hours used] / 1000
We can take a look at a concrete example to illustrate this better:
Daily kWh Saved: 40W x 12 hours / 1000 = 0.48 kWh
If you multiply 0.48 kWh by your electricity cost (let's say 7 units per kWh), you are saving more than 3.36 each day, which amounts to more than 1,226 per fan, per year. Now do the same for four fans!
Indeed, a 5-star BLDC fan with high efficiency will cost you more initially than a simple induction fan—maybe 2,000 to 4,000 more. But this extra cost should be considered as an investment instead of a loss.
You can figure out the payback period-the time when the energy savings will have paid for the extra cost of the first purchase by calculating your yearly savings.
For most residential users, this period is usually between 18 and 36 months, depending on the price difference and the hours of use. What is most important in the long run is that, after the payback period, the user will be saving continuously for the rest of the lifespan of the fan.
We have uncovered the fact that the star rating is not only a label—that is, it can be used as a potent tool for estimating and realising huge total savings that result from the lifespan of the equipment, reduction of the environmental footprint included.
So every replacement of the old fan or a new purchase simply becomes a step towards a well thought out, impactful decision both financially and ecologically.
Keep in mind: the initial low price of a cheap, non-rated fan is usually a catch that leads to higher bills month after month.
The 5-star fan investment is self-sufficient and continues to give you returns for years to come. So, make a move now and explore Victura Airmotion’s 5-star rated BLDC fans!
The star rating (usually 1 to 5 stars) is a very simple and direct measure of a fan's Environmental Efficiency Ratio (EER). It tells the amount of air that the fan releases per unit of the power (in Watts) it uses, as determined by a body like the BEE, a government agency.
Star ratings are important as they are the easiest way to understand the fan's power consumption. One higher star-rated fan will use considerably less electricity for a given period of time than the other and hence the utility bills for the whole month will be cheaper.
The foremost benefits are massive energy savings (up to 60% less power), a quicker payback period, a more silent working condition, and an increase in the robustness of the product as a result of the employment of highly efficient BLDC motor technology.
Indeed, the points a rating system gives a fan energy label are Limited Authorities for the rating systems. Values on physical tags inform the user about the duration of the norms applied to the labeling.
Five-star fans incorporate advanced technology of a Brushless Direct Current (BLDC) motor to a large extent, thereby consuming several times less power to deliver the same volume of cool air. Usually, a 1-star fan comprises an old generation, low-efficiency induction motor and thus uses more electricity than a newer model.
Generally, a 1-star fan or non-star rated one may take 75–80 Watts (W) to operate, whereas a 5-star, high-efficiency fan has only 28–35 Watts (W) of power requirement, thereby creating a gap of 40-50 W per hour of use between the two.
