Qatar Cool demonstrates how it ’ s possible to be a world-leading , wholly sustainable district cooling provider in a region with scarce water and soaring temperatures
Qatar boasts temperatures that rarely drop below 23 degrees , something which , along with its many shopping opportunities and luxury hotels , makes the country hugely appealing to tourists wishing to escape cold winter months .
However , the climate comes with its challenges : water is a precious resource , and air conditioning , an energy-intensive system , is required almost all year round .
A far more sustainable system is district cooling . Rather than use electricity to cool the air like conventional air conditioning does , it employs chilled water that is transported through underground pipes , and can be recycled from a number of sources like seawater . Qatar Cool , a global leader in district cooling , uses Treated Sewage Effluent
( TSE ) in two of its cooling plants , which is essentially wastewater that has been filtered of contaminants .
Sustainable cool Chief Executive Officer Yasser Salah Al Jaidah explains that its main benefits are energy efficiency and savings in both operational and capital expenditure . “ We reduce electrical consumption by almost half . Air conditioning is at its peak 75 % of overall electricity consumption during the summer months , so that ’ s huge . Obviously as a consequence we reduce CO2 emissions , by reducing the demand for electricity .”
A recent study they completed found that over the last eight years they have saved over a billion tonnes of CO2 , equivalent to 1.9bn kilowatt hours of electricity . The cooling system
