According to the ENGIE’s webpage, “District heating and cooling systems” (2013) ENGIE aims to provide comfort to the public and conserve nature. ENGIE was awarded to be the “world’s largest independent provider of urban cooling networks”. Currently, they are managing 320 systems globally and can be seen in France, the USA and even in Malaysia. The webpage focuses on two systems, heating and cooling. The heating system focuses on warming up the building or city with the help of hot water and surcharge steam. It uses available resources for heat generation such as natural gas. However, the cooling network supplies cold water to the air conditioning system. In this system, distribution facilities and cold water production is needed for the services. According to the webpage, ENGIE's cooling systems help make a district greener in terms of energy efficiency and reducing operating costs . One of the main outcomes of using cooling systems is that the district is able to use less energy. ...
