District energy systems connect central energy plants to multiple buildings across a city, providing heating and cooling efficiently and sustainably. Instead of each building maintaining its own system, energy is delivered via a water-based distribution network, ensuring reliable and eco-friendly thermal comfort. This approach optimizes resource use and reduces overall energy consumption, making it ideal for urban environments.
District Heating
District heating, the more common form of district energy, distributes hot water from central plants through insulated pipes to residential, commercial, and industrial buildings. These networks range from small communities to entire cities and can easily expand with additional pipelines and generation points.
Generation & Fuels
Heat is produced in two primary plant types:
-
Heat-only boilers that supply thermal energy.
-
Combined Heat and Power (CHP) plants that generate both heat and electricity. CHP plants enhance efficiency by using the steam from electricity generation to heat water for the district heating system or industrial processes.
Distribution Infrastructure
Hot water travels through insulated pipes under high pressure, maintaining temperatures between 70°C and 120°C (160–250°F) depending on weather conditions. Upon reaching end users, heat exchangers transfer energy from the district system to individual building systems for radiators and tap water.
Smart meters and control systems allow users to monitor and optimize their heat consumption effectively.
District Cooling
District cooling operates on similar principles, delivering chilled water from central plants to multiple buildings. It uses innovative techniques such as:
-
Free water cooling from lakes or seas
-
Heat pumps for combined heating and cooling
-
Sorption machines that utilize district heating energy for cooling
Compared to traditional air conditioning, district cooling offers:
✅ 35% lower electricity use
✅ 50% less CO₂ emissions
✅ Over 50% higher energy efficiency
