The Energy Conservation Act, 2001 gives the power to central government, who in consultation with BEE may:
- Specify the energy consumption standards;
- Prohibiting manufacture or sale or purchase or import of equipment and appliances not meeting the energy consumption standards.
- Direct display of labels on specified appliances;
Standards and Labeling has been identified as one of the key activities for energy efficiency improvements, for:
- having proven track record of being one of the most cost effective ways of reducing energy use;
- providing direct benefit to the consumer;
- enhancing the product quality;
- strengthening the competitive markets
- helping domestic industry to compete in markets where norms for energy efficiency are mandatory.
- being based on partnerships of all stakeholders.
S&L programs impact the energy savings in the medium and long run, as most of the equipment and appliances that will account for building energy use, say 20 years from now, have not yet been manufactured.
In India, the labeling program under BEE has been launched. The star rating ranges from 1 to 5 in the increasing order of energy efficiency and gives choice to consumer for choosing equipment or appliance. A typical comparative label is:

- The user of label to maintain the list of labeled equipment and submit to BEE every six months.
- A list of labeled equipment and information on the label will be maintained by BEE and will be made available to public through publication and on its website,
The user of label shall be solely responsible for ensuring:
- for the accuracy of the information displayed on the label;
- use of label only for equipment/models for which agreement is made.
- BEE will work towards creating a larger market for energy efficient equipment through consumer awareness and consumer education.
- BEE will appoint an independent agency to evaluate the program impact and process of implementation on a periodic basis. The scope of evaluation will include the impact on sales, energy consumption, cost, consumer purchasing behavior, manufacturing, national energy use and environment.
- BEE will review the scheme periodically to determine the need for revision or amendment or termination of the scheme.
Label Verification Process
- The BEE will verify the label content, and the manner of display of label for each equipment / model on a regular basis.
- Verification testing will be conducted in an independent laboratory registered with BEE.
- The label content can be challenged by any person by submitting the challenge to BEE in writing.
- The Committee will recommend whether to conduct a challenge test, keeping in view the basis of the complaint and examination of past records.
- The decision of BEE whether to conduct the challenge testing will be final.
- Verification testing will be conducted in an independent laboratory registered with BEE.
- If the equipment fails the challenge testing, the enforcement process will be followed.
- If the equipment fails the verification / challenge testing, then the matter will be placed before the Committee and user of the label will be informed about the failure.
- The user of the label has the option to go in for second test.
- If the equipment passes the second test, then no further action would be taken and equipment would deem to confirm to label.
If the equipment fails the second test, then the user of the label will:
- correct the label or remove the defect / discrepancies for new equipment yet to be shipped;
- change particulars / information on advertising material.
If the user of label fails to comply with the direction issued after failure in second test, then:
- Use of label for that model will be prohibited.
- BEE will inform the consumers about the failures of the equipment/model by wide publicity.
- BEE may advise the government to debar the equipment/model and/or the user of label from participating in any public tender.
Registration of Independent Testing Labs
- An independent laboratory with a valid accreditation from NABL or other international accreditation in force (with NABL approval) for the test procedures (energy efficiency and other performance tests) can register with BEE.
- The laboratories may be reviewed initially during registration and then on a regular basis, and in case any laboratory ceases to fulfill any condition laid down at the time of registration, registration will be withdrawn.
- If the test results of a particular lab are consistently found to be incorrect, then registration of the lab will be withdrawn, and wide publicity will be given of disqualification.
Star rating of appliances
The following sections tabulates star rating criterion for appliances as per BEE schedule for respective appliance:
Tubular Fluorescent Lamps

|lm/W at 0100 hours of use||<61||≥61 & <67||≥67 & <86||≥ 86 & <92||≥92|
|lm/W at 2000 hours of use||<52||≥52 & <57||≥57 & <77||≥77 & <83||≥83|
|lm/W at 3500 hours of use||<49||≥49 & <54||≥54 & <73||≥73 & <78||≥78|
Applicable to single-phase split and unitary air conditioners of the vapour compression type, for household use up to a rated cooling capacity of 11 kW and that fall within the scope of IS:1391 Part-1 and Part-2, being manufactured, imported, or sold in India.
Star rating for room air-conditioners
BEE has also specified voluntary schemes for cassette type, floor standing type, ceiling / floor type, and corner AC units. The star rating for these units is same as that of split type AC given in tables above.
Applicable to oil immersed, naturally air cooled, three phase, and double wound non-sealed type out-door distribution transformer. The standard rating covered is 16, 25, 63, 100, 160, and 200 kVA and non-standard ratings from 16 kVA to 200 kVA.
|Max losses at 50 % (W)||Max losses at 100 % (W)||Max losses at 50 % (W)||Max losses at 100 % (W)||Max losses at 50 % (W)||Max losses at 100 % (W)||Max losses at 50 % (W)||Max losses at 100 % (W)||Max losses at 50% (W)||Max losses at 100 % (W)|
For non-standard ratings between 16 to 200 kVA, the applicable losses at corresponding loading shall be determined by adding pro-rata difference of loss to the loss of the nearest lower capacity transformer losses, i.e.
LossNS = (KVANS - KVASL) / (KVASH - KVASL) x (LossSH - LossSL) + LossSL; where NS is non-standard, SL and SH are for standard capacities just below and above the non-standard rating.
LossNS = (KVANS - KVASL) / (KVASH - KVASL) x (LossSH - LossSL) + LossSL;
where NS is non-standard, SL and SH are for standard capacities just below and above the non-standard rating.
Frost free (no-frost) refrigerators
Applicable to electric mains powered frost free refrigerating appliance of the vapour compression type intended for household and similar use being manufactures, imported, or sold in India.
Star rating for frost free refrigerators
Direct cool refrigerators
Applicable to electric mains powered direct cool refrigerating appliance of the vapour compression type intended for household and similar use being manufactures, imported, or sold in India.
Star rating for direct cool refrigerators
All symbols have the same meaning as that for frost-free refrigerator, except Tested Energy Consumption (Et) is as determined by AS/NZS 4474.1 : 1997 and target temperature of freezer compartment is taken as -6 °C.
Applicable for 3-phase squirrel cage induction motor for continuous duty operation of ratings from 0.37 kW to 375 kW and conforming to minimum performance requirements of IS 12615 : 2011.
