Ministry of EnergyDefinition of Energy Saving Policies


To encourage the efficient use of energy and other resources, national governments and regional authorities have issued regulations, which mandate the provision of information to consumers regarding the energy and water consumption of household appliances and associated performance characteristics.

Energy Saving Policies

This information is usually conveyed by labels attached to appliances at the point of sale and also by brochures provided by manufacturers.

The RAC lists the reference testing labs, the sampling techniques, the tests and the acceptable tolerances.

Manufacturer / Importer should attest that its product attends the requirements on electric safety and energy efficiency.


Gaps and Challenges

More calibration / testing laboratories are needed for strategic schemes.

More government investment is needed to improve the existing infrastructure.

Market surveillance has an strategic role in labeling programs and need to be successfully implemented.

Industry is becoming more refractory to systematic revisions of energy efficiency levels.

Demand increases in quantity and complexity.

Uncertainty Reporting of Measurements

Methods for measuring declared values for energy and water consumption and performance characteristics must be of sufficient accuracy to provide confidence to governments, consumers and manufacturers.

The repeatability of a test method must be sufficiently accurate for comparative testing.

The reproducibility of a test method must be sufficiently accurate for the determination of values which are declared and for checking these declared values.


Ways to assess uncertainty

Bottom-up method (GUM)

In this method, the test result y is expressed as a function of input quantities.

In the case of home laundry appliances, the y may be one of the final test results like water consumption, energy consumption, washing performance, spin speed, spin drying performance, program duration or rinsing efficiency.

The input quantities may be temperature, masses, times, power, etc.


Ways to assess uncertainty

Top down method (IEC 61923 and ISO 5725)

In this method the reproducibility standard deviation isestimated from testing of the same machine (or the samemodel) in different laboratories using the samemeasurement method. This testing is in general named ´ringtest´ or ´round robin test´. The reproducibility standarddeviation of the test results can then be seen as the inherentuncertainty of the measuring method as it may be influencedby remaining differences in the ambient, the people andwhatever else may be different between differentmeasurements in different laboratories.

Because the eye's sensitivity changes with thewavelength, the output of lamps is commonly measuredin lumens, a measure of the power of light as perceivedby the human eye. The luminous efficacy of lamps is thenumber of lumens produced for each watt of electricalpower used. The luminous efficacy of a typical CFL is50–70 lumens per watt (lm/W) and that of a typicalincandescent lamp is 10–17 lm/W. Compared to atheoretical 100%-efficient lamp (680 lm/W), CFL lampshave luminous efficiency ranges of 7–10%, versus 1.5–2.5% for incandescents.

Energy efficiency efforts should not be a trade-off to safety

Safety/Energy efficiency standards/regulations require measurements to show conformity of products and services with specifications

Measurements carried out by testing labs require calibrated standards and meters and certified reference materials. Testing labs need to participate in proficiency tests.

Calibration labs need reference standards traceable to primary standards from National Metrology Institutes (NMIs)

NMIs need to participate in SIM international comparisons on physical, chemical and biological quantities
