Monday, 11 February 2019 16:30 Introducing Minimum Energy Performance Standards A global review of existing standards for lighting and recommendations for the development of Minimum Energy Performance Standards (MEPS) for lighting in SADC and EAC, 1
The inventory covers • the most commonly used international organisations and standardisation bodies in the field of Light and Lighting • reviews national regulations, standard related to energy efficiency in both indoor and outdoor applications • commonly used environmental certification systems related to energy efficiency and lighting in the world today 2
Aim of Inventory • Guidance for future Technical Committees within the SADC and EAC region responsible for the standards specification process in Light and Lighting • Guidance for the adoption and implementation of; o Standards and requirements in lighting applications o Certification systems o GPP (Green Public Procurements) or national regulations 3
Organizations for standardization in Light and Lighting - on national, regional and global level Global Global European European ISO IEC CEN CENELEC Applications Products TC 274 TC 169 in Light and Lighting safety requirement National standardization National standardization bodies bodies 4

Secretariat: Brussels CEN - the only recognized European organization according to Directive 98/34/EC for adoption of European Standards CEN and CENELEC have dedicated agreements with ISO and IEC, of the international standards to international trade and markets harmonization. 8
Priority items in ISO TC274 – CIE – CEN Aging population Visual and non-visual effects of light Integrative Lighting (Human Centric Lighting) Visual and non-visual effects of light – Lighting quality CRI / Flicker – Photometric data on LEDs Energy Performance Energy requirement for lighting – Lighting system approach Adoptive Lighting (Smart Lighting) Intelligent Lighting Systems addressing human needs 9
Summery of Standards - suitable for the Technical Committees Proposed suitable areas in application standards to be used in the design process of energy efficient installations and to be adopted and engaged in by the Technical committees under EASC and SADCSTAN. Covering the following criteria’s on energy efficiency in light and lighting; o Presentation of photometric data for lamps and luminaires o Energy performance for lighting on indoor and outdoor lighting application o Lighting design requirements of indoor and outdoor applications 10
