District cooling

Because of the climate in Oman and because of the wealth of Omani people there are many air conditioning systems. Those systems need a lot of electricity, around 70% of total building energy, and therefore it is necessary to reduce the consumption of energy, wherever it is possible. One way of reducing it without giving up a cool climate is “District Cooling”. It works similar to the principles of district heating, which is more common in European countries. There is a central plant, which chills water that is pumped through a pipe network to the buildings of the customers. In each building, which is connected to the pipe network, there is a water circuit that circulates the cold water and produces an air conditioned environment. In the central plant the warm water will be re-chilled again. Compared to common air conditioning District Cooling can save up to 55% of energy. Beside this positive effect for the environment it also helps to reduce the energy and maintenance costs for the buildings.
District cooling is especially suitable for large-scaled, high density population developments in cities, there are already lot of projects for District Cooling in the Gulf-region, for example the Metro in Dubai, or the Knowledge Oasis (KOM) in Oman.
Because the Omani people have a tradition in building their own houses we think the first projects concerning district cooling should be public buildings, District cooling would be very suitable for Economy and Knowledge Centers, but also for MOMO (Muscat Optimized Mobility Organization).
