A consortium of "Saudi Tabreed" and the "SNC Lavalin-Canada" signed a contract with " Rayadah investment company" (RIC) , the developer of King Abdullah Financial District in Riyadh, a contract to design and build a district cooling services for the air-conditioning systems of the office towers at the King Abdullah Financial District including the operation and maintenance of the system for a period of ten years. The total capacity of the project (100) thousand tons of refrigeration, and is the largest of its kind in the Kingdom. The project will be implemented in two phases the capacity of each stage is Fifty thousand tons of refrigeration, and the first phase will be commissioned in the first quarter in 2011, the second phase will be commissioned in the first quarter in 2012.
GCC countries witnessed over the past decade a significant expansion in the field of district cooling services for air conditioning of offices and residential towers as this technique provide gains from economic, environmental, performance applications of this technology resulted from the substantial saving in power consumption (up to about 40%) in comparison with the conventional air-conditioning systems also this technique use refrigerants that are consistent with the environmental standards imposed by the United Nations (Kyoto and Montreal) protocols reducing the emissions of carbon dioxide to preserve the ozone layer surrounding the atmosphere, in addition this technique uses treated sewage water to be in line with the standards of green buildings imposed by the U.S. Green Building Council (LEED).
District Cooling in brief is to produce a low temperature water from central station of industrial chillers of large capacity and distributed through a network of pre-insulated pipes and connected to each building via heat exchangers to reduce the temperature of the water used for air-conditioning in the building and retrieved the high temperature water to the central station to re-cooled and then pumped back to the network.
"Saudi Tabreed" is a closed joint stock company owned mainly by "ACWA Holdings" which specializes in the development of infrastructure in many areas, and National Central Cooling UAE which is one of the largest companies specialized in the development and operation of district cooling schemes in the world, Tabreed owns 44 station with capacity of more than 449 thousand installed tons of refrigeration and is found in a number of the GCC states.
Saudi Tabreed recently signed a similar contract to develop the cooling system for the "Saudi Aramco" company to serve the company premises in Dhahran having cooling capacity of 32000 tons, and the company is currently working to develop similar projects in Medina, Jeddah and Makkah.
Mr. Mohammed bin Abdullah Abu Nayyan, Chairman of the Board of Directors of Saudi Tabreed announces that "The company is proud to participate in the infrastructure works for King Abdullah Financial District, which is one of the most important and strategic projects in the Kingdom which includes all the important financial and economic institutions. And also reflects the awareness of the Rayada Investment Company officials for the importance of environmental and economic impacts of such modern technology resulted from the reduction in power consumption needed to run air-conditioning systems, which normally consumes an average of 70% of the electricity for the buildings.
