Experience

UDEI inherits Qatar Cool’s experience in building and operating five cooling plants across two major districts, taking the experience internationally.

The West Bay District

The total area served is more than 1.9 million square meters (20 million square feet), the length of the Pipe Distribution Network (PDN) is 28 kilometres (17 miles) of underground supply and return pipelines with pre-insulated steel pipe. The three operational plants are connected to the network and currently serving over 69 towers of Doha’s West Bay skyline. Qatar Cool serves such towers as government offices, ministries, hotels, residential, commercial, metro, and retail complexes.

Qatar Cool has implemented TSE in all three cooling plants in the West Bay district, two of which receive direct TSE and the third via an onsite Reverse Osmosis (RO) plant. Since 2015 Qatar Cool has saved over 6 million m3 of potable water.

Plant One

Plant one was inaugurated in 2006 as Qatar Cool’s first cooling plant. The plant has a cooling capacity of 25,000 Ton of Refrigeration (TR) and a Thermal Energy Storage Tank of 25,000 TRh. The cooling plant houses 10 centrifugal chillers.

Plant Two

Plant two became operational in 2009 with a cooling capacity of 32,500 Ton of Refrigeration (TR) and a Thermal Energy Storage Tank of 20,000 TRh. The cooling plant houses 13 centrifugal chillers.

Plant Three

The plant has a cooling capacity of 35,000 Tons of Refrigeration (TR) and a Thermal Energy Storage Tank of 25,000 TRh. It is unique in comparison to its sister plants. Plant three is our first plant certified with a Leadership in Energy and Environmental Design (LEED).

The Pearl Qatar District

The total area served is 3.9 million square meters (41 million square feet) of the man-made island, the length of the Pipe Distribution Network (PDN) is 92 kilometres (57 miles) of underground supply and return pipelines with pre-insulated steel pipes with diameters ranging between 75 mm to 1400 mm. All Energy Transfer Stations (ETS) are linked to the plant through a Fibre Optic Communication Network allowing for centralized monitoring and control.

On each customer’s premises, Qatar Cool installs, operates and maintains an Energy Transfer Station (ETS). The ETS is configured to allow redundancy and reliability. The control system operates both the primary and the customer’s secondary systems. Our engineers continually work with the building operators to introduce advanced energy saving and failsafe concepts.

The Pipe Distribution Network (PDN) is strategically designed and executed to achieve high energy efficiency, operational simplicity, and concurrent maintainability. PDN operational parameters are monitored 24×7 from our Central Command Centre (CCC) supported by active patrolling and surveillance on site.

Integrated District Cooling Plant (IDCP)

In 2010 we inaugurated the world’s largest district cooling plant on the then newly developed manmade island, the Pearl Qatar. Our cooling plant has a staggering cooling capacity of 130,000TR and serves the 3.9 million square meter island. The Pearl Qatar houses numerous Heat Exchange Stations (HEX) around the island, allowing us to pump sufficient cooling capacity to our customers and keeping its reliability and efficiency, due to the sheer size of the island.

Gewan District Cooling Plant (GDCP)

This cooling plant, with a cooling capacity of 18,000TR, will provide sustainable cooling solutions to the emerging Gewan Island. The island once complete will extend over 4 hundred thousand square meters and hold a combination of residential and commercial customers.

The plant will utilize a Reverse Osmosis (RO) plant, with a unique feature of using sea water, thereby eliminating the need to use fresh/potable water. The plant is designed to provide an average annual plant efficiency of 0.83 Kw/TR, achievable by selecting the efficient chillers, pumps, and other components.

To limit heat gain to the building, the external façade has highly insulated walls and low shading coefficient glazing. 30% of the building’s façade will be covered with a vertical garden, aside from the aesthetic appeal the green wall will provide improved air quality and a decrease in noise pollution. We will use drip irrigation for the vertical garden which will reduce water consumption.
