3. District Cooling In Kuwait- Introduction GCC countries have today one of the highest environmental foot print per capita in the world in terms of peak electric load/Capita, carbon emissions/Capita and annual power consumption/capita. With the Global move to reduce carbon emissions and preserve the environment, and with the power failures and crises in Kuwait occurring since the summer of 2006, it is essential to adopt energy efficient environmental friendly solutions to meet the future expected growth in Kuwait. 60 to 70% of building peak electricity load and over 50% of the building annual energy in the GCC is consumed by air conditioning equipment. District Cooling along with better building designs are playing a vital role in curbing power consumption related to air conditioning and can offer numerous technical, commercial and environmental benefits to the government and end users. 3

11. District Cooling In Kuwait- Total Government Benefits

12. District Cooling In Kuwait- Total Government Benefits (Cont’d) 1,200,000 Ton additional peak cooling load growth is estimated in the next three years in Kuwait with estimated actual load of ~890,000 Ton. With district cooling and thermal storage, the following can be achieved: Electric Demand of the 1,200,000 Ton is 919 MW for DC with TES tank as compared to 2,233 MW with traditional Air Cooled systems. Power consumption of 2,730 GWH for DC as compared to 5,471 GWH for traditional A/C systems. Government Infrastructure cost reduction with district cooling is around US $ 3.3 Billion for Power Water & Sewage Plants, auxiliaries, Transmission and distribution costs. Government costs for fuel consumption in electricity generation can be reduced by US$ 333 Million thus increasing sales revenue. CO2 Emission reduction by2.95 Million Ton. 12

13. District Cooling In Kuwait- Other Benefits of District Cooling Additional benefits of district cooling: Due to its economy of scale, district cooling have the potential of incorporating key energy efficiency measures and renewable energy easier than traditional air conditioning. Decreasing total developers’ construction cost by 8-10 % Maximize floor free space for commercial utilization by eliminating A/C plant and bulky outdoor equipment. Central plant room uses ozone friendly refrigerant such as HFC-134a. Leakage from central plant is accurately monitored and controlled and is significantly lower than many scattered plants or units. District Cooling plants are usually sized at a size of 80% of multiple stand alone plants or DX systems due to diversification of loads leading to lower capital and operating costs. 13

14. District Cooling In Kuwait- Other Benefits of District Cooling Higher human comfort conditions can be achieved with District Cooling: Lower indoor humidity level resulting from lower and better chilled water temperature control, Lower objectionable noise and vibration in occupied areas by locating chillers or condensing units in a remote site, Less maintenance disturbance Higher system reliability can be achieved with district cooling : Industrial grade equipment is used with much lower failure frequency than commercial equipment; with a reliability index in excess of 99.94% as documented by IDEA Central plant room has round the clock maintenance and operation staff. This allows proper preventive maintenance and quicker response time in the event of failure. 14

15. 15 District Cooling in Kuwait Benefits of Thermal Energy Storage (TES)

16. District Cooling In Kuwait- Benefits of Thermal Storage Benefits of thermal storage: Store cooling energy during low load conditions hours to be used during peak hours Level the electric demand throughout the day thus eliminating the variation in cooling electric demand between day and night Reduce chiller capacity and peak power demand by 20% Reduce annual power consumption by 3-5 % Reduce capital costs by 8-15 % depending on total plant capacity Reduce water consumption by 5-7 % by shifting the load to night time with lower ambient temperatures Offer back up during power shut down for part of the load. Provide reserve water for fire fighting in case of emergencies 16
