Introduction
Energy Efficiency program for domestic appliances:
• Energy efficiency standards• Energy labels • Incentive schemes• Procurement programs• Information and awareness raising programs

Energy Efficiency Standards
• Well-defined protocols (or laboratory test procedures) for accurate estimate of energy performance
• Target limits on energy performance based on specified test protocols

Introduction](https://reader034.vdocuments.net/reader034/viewer/2022042509/5f9230e5acf9a7296a1e9c43/html5/thumbnails/5.jpg)
Types of Energy Efficiency Standards
• Prescriptive standards• Require that a particular feature or device be fitted or
installed in all new products• Minimum energy performance standards (MEPS)
• Prescribe minimum efficiency levels or maximum energy consumption that appliances/equipment must achieve
• 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 overall average is met

Test Standards
• Test methodologies/procedures• Appliance performance• Appliance energy consumption• Appliance Efficiency classes
• Enable appliances/equipment to be compared on a fair basis

Energy Labels
• Comparative energy labels• Informs the consumer that the product meets the required
standard or eligibility criteria• Allow consumers to compare and form a jugdement on
energy performance among similar products using • Discrete categories of performance• Continuous scale
• Endorsement labels• These are seals of approval given according to a specified
criteria• Energy labels can stand alone or complement energy
standards

SANS 941
• Formulate performance test standards and appliance energy labels
• Appliance passive standby power requirements
• Follow the European system for performance standards and labelling
• Add the European directives for appliance labelling as National annexes to the respective performance standards
• Harmonisation was key
