IV Seminar on Energy Efficiency in Latin America and the Caribbean

Minimum Energy Performance Standards (MEPS) to promote the transition


Energy-efficiency standards are procedures and regulations that prescribe the energy performance of manufactured products, sometimes prohibiting the sale of products that are less efficient than a minimum level.

Two possible meanings:

1) well-defined protocols (or laboratory test procedures) by which to obtain a sufficiently accurate estimate of the energy performance of a product in the way it is typically used, or at least a relative ranking of its energy performance compared to that of other models; and

2) target limits on energy performance (usually maximum use or minimum efficiency) based on a specified test protocol

  • Three types of energy-efficiency standards:
    • ■ prescriptive standards
    • ■ minimum energy performance standards (MEPS)
    • ■ class-average standards
    • Prescriptive standards require that a particular feature or device be installed in all new products.
    • Performance standards prescribe minimum efficiencies (or maximum energy consumption) that manufacturers must achieve in each and every product, specifying the energy performance but not the technology or design details of the product.
    • Class-average standards specify the average efficiency of a manufactured product, allowing each manufacturer to select the level of efficiency for each model so that the overall average is achieved.



Lamps (Product ) Performance Criterion

  • Establishing performance standards or defining what products are acceptable to a scheme or market and which will be discouraged through mandatory or voluntary measures, is essential for almost all phase-out schemes.
  • The most important factors to bear in mind when specifying the parameters to be included in a performance standard are:
      • Specify only the parameters which are important, adopting existing international performance standards, where available. This will increase the likelihood of receiving compliant products at reasonable prices from suppliers, and make managing the scheme administration easier.
      • Ensure that test standards exist to accurately, reliably and consistently verify the product performance. If a product is in compliance with international safety standards, the product shall be considered safe. Health and safety issues which relate to potentially hazardous situations and or materials used in the product may be covered by additional requirements.


product coverage criterion
Product Coverage Criterion

decision on product coverage will be largely dependent on the mix of lamps in the market and the objectives of the phase‐out scheme

include consideration of what loopholes might be possible and how to avoid or mitigate them. (Eg . Base type , geometry etc.)

exemptions or less stringent requirements are only applied to products that can be truly warranted: i.e. “special purpose lamps” that have very unique performance needs ( eg. Marine lights, traffic signals, navigation lights, incest lights etc)

mitigation options
Mitigation Options

Set a wattage limitation for niche or special purpose products to minimise their sales growth into other areas

Allow an initial exemption or modification of the requirements but to set maximum market penetration level.

Develop a specific category for special purpose lamps which are required to clearly and prominently state their intended purpose on product packaging and all forms of product information, along with a statement that they are not suitable for general lighting purposes.

Set a schedule for phasing‐out exemptions over time


Generic product performance requirements (example)

Note : International, regional and national requirements exist on specific product information to be shown on the product (packaging) or in leaflets or websites.



Energy performance of lamps

  • There are four main options for specifying energy performance:
  • Single wattage limitation
  • Single minimum efficacy level
  • Lumen output groups
  • Performance curves


en lighten phase out option 1
En.lighten : Phase Out Option 1

Countries develop phase out policies/plans in such a manner that the minimum luminous efficacy of all the lighting products follow the curve in red colour however the other parameters with regards to the product quality would be as in tables (shown in previous slides).

A review three years after the implementation of the phase-out, monitoring the trends of the halogen market and analyzing the development of LED alternatives

Omni‐directional Lamp Efficiency ≥ Ф / (0.836√Φ+0.04655Φ ) (lm/W)

en lighten phase out option 2
En.lighten : Phase Out Option - 2
  • Countries develop phase out policies/plans in such a manner that the minimum luminous efficacy of all lighting products follow curve in See curve yellow, however the other parameters with regards to product quality would be as in tables
  • The target date for complete phase out of ILs would be 31 December 2015
  • Depending on the growth of EE lighting products, a further revision of the luminous efficacy values as under curve in yellow colour would be scheduled for revision by 2020

Omni‐directional Lamp Efficiency ≥ Ф / (0.2112 x √Ф + 0.01176 xФ)) (lm/W)

Note: All requirements to be tested at a batch of 10 product samples. The batch of products shall be considered to comply with the requirements set out in this document if the average results of the batch do not (adversely) vary from the limit, threshold or declared values by more than 10 %)
