DOHA: Msheireb Downtown Doha (MDD), the multi-billion dollar ambitious project of Msheireb Properties, has opted to install energy efficient ‘District Cooling’ (DC) technology to cool its buildings instead of using power-intensive conventional air-conditioning system, said a press statement yesterday.
Msheireb Properties, a subsidiary of Qatar Foundation (QF), announced that its flagship project has achieved permanent 11 kilovolt (kv) power connection in its first DC plant in partnership with Qatar General Electricity and Water Corporation (Kahramaa) and is now operational and in the testing stage.
District cooling is an innovative and energy efficient cooling system which delivers chilled water via an underground insulated pipeline to offices and buildings needing cooling.
The DC technology is not only cost effective but also an environment-friendly system which uses 30 to 40 percent less energy than conventional refrigeration system, resulting heavy reduction in CO2 emissions.
The power connection represents a major milestone in the delivery of MDD as the permanent electricity supplies will allow for the operation of highly efficient water cooled chillers in the plant which will cool the Diwan Amiri Quarter with chilled water.
This plant will be part of a larger district cooling system which will comprise two district cooling plants (DCP-1 and DCP-2). Once fully operational, the total capacity of the district cooling system will be 29,250 TR, sufficient to serve the cooling needs of the entire MDD development.
“We are extremely proud to have completed this major “power ON” milestone for our MDD project in close cooperation with Kahramaa. It is the result of the tireless efforts of the entire Msheireb Properties team, Kahramaa management and their field engineers. Our environmental considerations are deeply incorporated into each element of the MDD master plan, underscoring our commitment to sustainable development and industry best practice,” said Abdulla Al Mehshadi, CEO of Msheireb Properties.
The MDD district cooling system will enable significant savings in comparison to the power consumption of conventional air cooled chillers. The plants will use chillers of the highest efficiency, which will be able save up to 12.6 million kWhs per year compared to similar conventional chillers.
These developments reflect Msheireb Properties’ commitment to attain the highest of standards in efficient energy and water consumption, confirmed by its LEED certification and sustainability objectives.
In September, Msheireb Properties and Kahramaa activated the first 66kV energised underground substation in MDD. The development will eventually be powered by two 66kV primary underground substations that will feed 11kV power to 40 underground distribution substations in each building and both district cooling plants.
