6. District Cooling – opportunities and challenges
Cooling represents 70% of peak energy consumption across the GCC
DC uses 50% less energy than Conventional Cooling
DC life cycle costs ca. 16% lower than Conventional Cooling

Opportunities
Challenges
Economies of scale – higher efficiencies and lower capital cost of chillers
Various uncertainties exist in the data used at system planning and design stages.
Alternative condenser cooling – cooling towers, river water, waste water
– more efficient than air-cooled
Uncertainties in cooling load calculation: Outdoor weather condition including the outdoor air temperature, relative humidity, solar radiation, etc
Alternative refrigerants –
High variance in load causes large fluctuation in performance
