The Energy Conservation Act, 2001 gives the power to central government, who in consultation with BEE may:

Standards and Labeling has been identified as one of the key activities for energy efficiency improvements, for:

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.

Impact on Refrigerators: US Example

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:

Overview of the Labeling Process

  1. Identify and prioritize products for labeling;
  2. Set up Steering Committee including all stakeholders;
  3. Identify critical issues and organize technical subcommittees;
  4. Finalize test procedures, lab specifications, minimum technical qualifications;
  5. Assess market and product characteristics w.r.t. energy efficiency;
  6. Develop technical criteria for labeling;
  7. Develop implementation and enforcement plan;
  8. Notification after finalizing all the technical and admin details;
  9. Launch labels;
  10. Consumer awareness campaign;
  11. Check and challenge testing; and
  12. Program monitoring, review, and updates.

Criteria for selecting products for labeling: Select products that:

  • that use a significant amount of energy;
  • that are present in most households or where rapid growth is predicted;
  • for which energy-efficient technology exists but is not being used in most products in the market; and
  • for which there is a significant variation in the energy efficiency of different units.

Establishment of a rating plan:

  • Compile data on energy consumption of Indian equipment and benchmark against international ones.
  • Comparison to be on an equitable terms, taking into account variations in test procedures, product design, and other considerations.
  • Target of the programme is to achieve highest international efficiency levels for that category.
  • Highest efficiency may be achieved gradually.
  • Recommend time for achieving highest efficiency.
  • Rating plan to be reviewed periodically.

  • CEC (Comparative Energy Consumption): It is the nominal energy consumption of the model and is based on PAECav. It appears on the label.

    CEC = K * Vadj + C (kW⋅h/year)

  • K is constant multiplier (kW⋅h/litre/year)
  • C is constant fixed allowance (kW⋅h/year)
  • Vadj (Total Adjusted Storage Volume): The rated storage volume of a compartment of fridge adjusted to compensate for heat loadings if its temperature is different from fresh food compartment viz freezer.

    So, Vadj = fresh food compartment volume + Adjusted Volume Factor * target compartment volume + ... (litre)

    Adjusted Volume Factor = (test room temperature - target compartment temperature) / (test room temperature - fresh food compartment temperature)

  • Tested Energy Consumption (Et): The value of energy consumed in as determined by IS 15750 : 2006 for a period of 24 hours.
  • Projected Annual Energy Consumption (PAEC): The estimated annual energy consumption.

    PAEC = Et * 365 / 1000 (kW⋅h/year)
