SEEC’s Mission Support preserving the national energy resources to enhance the national development and economy through the rationalization of energy consumption and improving energy efficiency in order to achieve the lowest possible levels of energy intensity.

SEEC’s Mission…continue SEEC’s main activities include: Ø Development of policies, rules and regulations governing EE and support their implementation. Ø Support the integration of the stakeholders’ efforts to improve EE and coordination amongst them. Ø Promote EE awareness at both public and institutional levels. Ø Participate, as needed, in the implementation of EE pilot projects.

Samples of SEEC’s Activities Developing a “Holistic National Energy Efficiency Program”: • • Targeting main consuming sectors (Buildings, Industry and Transportation) Set EE Goals for each sector Coordinated by SEEC Implemented by Stakeholders

Energy Efficiency Program (EEP) objectives • Improve Kingdom’s energy efficiency in buildings, transportation, and industry • Design the energy efficiency initiatives with their energy savings goals, implementation mechanisms, and enablers • Engage key stakeholders: Government, businesses, and public

EEP framework EE Savings goals EE savings Sectors 6 EE sub-sectors with EE savings goals Initiatives to achieve the EE savings goals Buildings New buildings Initiatives Transport Industry Existing buildings New Existing fleet New plants Initiatives Regulations (specific to initiatives) Enablers to implement initiatives ESCO’s (Energy Service Companies) Funding Governance Awareness Existing plants Initiatives

Buildings objectives Increase energy efficiency in residential, commercial and governmental buildings by achieving international level of Energy Use Intensity (k. Wh. year / m 2) Lead by example: government buildings Improve & enforce standards of A/C energy efficiency ratios EER Enforce building code on new residential / commercial buildings Mandate thermal insulation Retrofit existing buildings Enhance other white goods energy efficiency standards Phase III Phase I Products initiatives Phase II Buildings initiatives Phase-out incandescent bulbs
