1 IV Seminar on Energy Efficiency in Latin America and the Caribbean Minimum Energy Performance Standards (MEPS) to promote the transition

2 Energy efficiency and Conservation Figure 1.14

3 Standards 3 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

4 Standards 4 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.

7 7 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.

8 Product Coverage Criterion decision on product coverage will be largely dependent on the mix of lamps in the market and the objectives of the phaseout 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)

9 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 phasingout exemptions over time

12 12 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

13 13 Comparison of options for specifying energy performance OptionDescriptionAdvantageDisadvantage Single wattage limitation This option involves setting a simple wattage limit to cover all lamps. For example, no lamp over 70W can be sold after a certain date. This approach is simple to write and communicate and could be effective if the goal is to move all lamps to CFL or better performance levels The approach restricts the level of savings that can be achieved. Single minimum efficacy level involves setting a minimum efficacy level (in lumens per watt) for all lamps. Simple to write and communicate With all available lamp technologies today, the lamp efficacy increases with light output, therefore if the level set is too high/stringent, it may be difficult for low lumen lamps to comply. Alternatively, if it is set too low, the potential incremental savings from brighter bulbs may be lost.

14 14 Lumen output groups Setting a lumen output equivalency group for the light output of todays standard incandescent lamps, combined with a maximum permissible wattage, or minimum efficiency (lumen per watt), for each equivalency group ( i.e. the maximum energy consumption or minimum efficacy of the replacement lamps) relatively easy to communicate and the wattages or efficacy of the replacement lamps in each lumen category can be tailored to ensure maximum savings at the various levels. Care must be taken when assigning the lumen equivalency groups. They must not be so wide that they encourage manufacturers to produce lamps that deliver less lumen in order to comply. This could result in the consumer switching to lamps from a higher lumen level in order to obtain the amount of light they have been accustomed to, which would have an adverse affect on the anticipated energy savings. OptionDescriptionAdvantageDisadvantage

15 15 Performance curves Based on establishing a curve that sets minimum efficacy levels (in lumens per watt as a function of light output). The curve is created by plotting the lumen out- put of todays lamps against their efficacy in lumens per watt. The data follows a natural curve with efficacy increasing as a function of light output. Would yield maximum efficiency benefits as it forces all lamps to be more efficient Lacks the simplicity of some of the above approaches and requires the use of formulas and/or detailed tables.
