EXECUTIVE SUMMARY Efficient Cooling Water-cooled cooling technologies continue to offer the highest energy efficiency, especially when cooled using recycled water, so we are pleased to report an increase in the market share of DC to 21%. Dubai’s DC capacity increased to over two million refrigeration-tons, and output was up 2.9%. The reduction in demand for cooling from other technologies meant overall demand, inclusive of DC, was down 1.2% on the previous year. Three schemes introduced in 2019 set new standards for cooling load density, with the average load for the best scheme under 99W/ m2. These schemes improved the average from 141W/m2 to 135W/m2. Three of the six most energy efficient plant are reporting for the first year. The average efficiency of the six best plant was 0.76kWh/TRh, well ahead of the 2030 energy efficiency target of 0.82kWh/TRh. At the other end of the scale, the average efficiency of the six worst performing plant was 1.51kWh/TRh. Energy efficiency for the sector remained at 0.90kWh/TRh. There were five additional thermal energy storage plant reported in 2019, of which three were newly commissioned and two were from a company’s first return. Those additions brought the total number of thermal energy storage facilities to 14. 2 million refrigeration-tons market share 0.76kWh/TRh 1.51kWh/TRh 16 RSB
