District cooling system as a utility infrastructure business – Contractual obligations of the district cooling operator
Introduction The district cooling system, according to IDEA’s “District Cooling Best Practice Guide”, is a long-term utility service business. By their very nature, district cooling systems are often structured as utility infrastructure. In this article, we shall explore the key characteristics of district cooling that distinguish it as a utility infrastructure business, as well as…
District Cooling Plant vs In-Building Chiller Plant: Understanding the Key Differences
Introduction The United Nations Environmental Program, in its publication titled “District Energy in Cities: Unlocking the Full Potential of Energy Efficiency and Renewable Energy”, stated that:• Cities account for over 70 percent of global energy use and 40 to 50 percent of greenhouse gas emissions worldwide.• Half of the cities’ energy consumption is for heating…
What are the benefits of chilled water storage in district cooling?
Introduction Chilled Water Storage, being a form of sensible energy storage, utilizes a large insulated tank as a storage vessel for chilled water. In District Cooling Plants, Chilled Water Storage is used to store the excess chilled water generated by the chillers during periods of low cooling demand. During peak periods, when the cooling demand…

What are the benefits of District Cooling?
District cooling systems are often structured as energy utilities which provide cooling energy as a service. As a modern, cost-effective and energy efficient cooling energy solution, district cooling delivers numerous benefits to its multiple stakeholders.
What is District Cooling?
In traditional in-building air-conditioning systems, each building is provided with their own refrigeration systems for producing chilled water. With the exception of a few larger scale developments, the majority of buildings which are smaller in size tend to adopt more energy intensive cooling technologies such as air-cooled packaged units or water cooled chiller units without thermal energy storage system.
District Cooling offers a sustainable and energy efficient solution for the modern urban development. District cooling systems produce cooling energy, in the form of chilled water, at a central chiller plant. The chilled water is supplied to multiple end-user buildings via a piping network for comfort cooling.
