Msheireb Downtown Doha complex to install 29,000 TR district cooling system

Date: 7 January 2014

Utilities-ME reports that Msheireb Properties’ $5.5bn (QAR 20bn) project Msheireb Downtown Doha (MDD) has opted to install energy efficient District Cooling (DC) technology to cool its buildings.

The project has achieved permanent 11 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. The DC chillers are estimated to save up to 12.6 million kWh per year compared to conventional air conditioning.

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.

“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.

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.

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.

In addition, Construction Week reports that photovoltaic (PV) solar panels at the $5.5bn (QAR 20bn) Msheireb Downtown Doha (MDD) project have been installed by renewable energy firm Innovations Unlimited ME. Roof-mounted modules will supply a portion of the electricity needs of the buildings within the first phase of the development.

As many as 2,072 PV panels and 37 inverters are being installed, feeding a total of 463.4 kWp (kilowatts at peak power) of electricity and will feed directly into the electrical grid of the development with the aim of significantly reducing the buildings’ carbon emissions.

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.
