18 Monthly Electrical Consumption (GWh) Monthly Electrical Load versus Monthly Average Ambient Temperature for Kuwait in 2005 and y = x R² = y = x R² = Monthly Average Temperature (C)

19 Energy & Utility Facts about Kuwait AC and lighting of buildings account for nearly 85% of peak electric power and 60% of annual electrical consumption. Fuel share in power plants is 84% for electricity and 16% for water. Subsidies electricity charges. Actual cost 40 fils/kwh. Energy Charge only, flat rate of 2 fils/kwh. No demand charge.

20 Building Energy Code of Practice in Kuwait, Past: The 1983 code was developed by MEW, MPW and KISR: Applicable to all new and retrofitted buildings of all types. The code covers electrical installations : Regulations including their operations energy and conservation measures in buildings. Basic energy conservation requirements: limits A/C peak power (Watt) per unit area (m 2 ) for air- and water-cooled A/C systems as well as lighting for: Residential buildings. Commercial buildings (including office, shops, mosques, schools... etc.).

21 1983 codes are documented in the following publications: (MEW / R-1) Regulations for electrical installations. (MEW/R-2) Procedures for approval of electrical and A/C drawings and connection of power supply for construction and buildings projects. (MEW/ R-3) Electrical load form and explanatory notes. (MEW / R-4) Regulations for testing of electrical installations before connection of power supply. (MEW / R-5) General guidelines for energy conservation in buildings. (MEW/R-6) Code of practice for energy conservation in buildings and appendices. (MEW / R-7) Rules and regulations for design of A/C system and equipment. (MEW/R-8) Rules and regulations for handing over engineering services (electrical and mechanical) to the maintenance authority. (MEW / S-1) General specifications for electrical installations.
