District heating and cooling

Heating and cooling networks: decarbonizing solutions

Heating and cooling networks provide solutions on the scale of a community, city or industrial basin, replacing thousands of individual heating or air-conditioning systems with a reliable, modern and economically competitive industrial system, making increasing use of renewable and upgraded energies (biomass).

Wastewater treatment plants, data centers, incineration plants, geothermal energy, biomass, etc. are all sources of electricity and heat to be exploited. The benefits? Greater energy efficiency, lower greenhouse gas emissions and renewable, local, cost-effective heat.

Hundreds of cities around the world have chosen us to operate and manage their heating and cooling networks: we provide heating, domestic hot water and air conditioning to public and private buildings. We help cities define their low-carbon strategy and intelligent energy management by developing mixes that encourage the use of renewable and alternative energy: geothermal, biomass, cogeneration or even recovery of heat produced by household waste incineration and wastewater treatment plants, etc.

District heating networks

District heating is a system that uses a singular central heat source to distribute hot water through a network of insulated pipes to multiple individual dwellings. The structure is usually used to fulfill heating and hot water requirements in apartment complexes.

Benefits of District Heating

  • Energy efficiency: District heating systems can be more energy efficient than individual heating systems because the heat is generated at a central plant and distributed through a network of insulated pipes, rather than being generated at each individual building.
  • Cost effectiveness: District heating can be more cost effective than individual heating systems because the costs of operating and maintaining the central plant can be shared among multiple users.
  • Reduced emissions: District heating can help reduce greenhouse gas emissions because the central plant can use renewable energy sources, such as solar or geothermal, to generate heat.
  • Improved reliability: District heating systems can be more reliable than individual heating systems because they are less prone to breakdowns and can be more easily maintained and repaired.
  • Space savings: District heating systems do not require individual heating units in each building, which can save space and reduce clutter.
     

Business Cases

Harbin - Heilongjiang
Harbin district heating network

Veolia is responsible for the construction and operation of the heating network in Harbin, capital of Heilongjiang province, with a 30.1 million m2 heating area. Demolition of over 500 small coal-fired boilers has improved the air quality in the city and energy efficiency.

Jiamusi - Heilongjiang
Jiamusi district heating network

Committed to improving the quality of heating in Jiamusi, Veolia followed the overall plan of the municipality and launched the complete reconstruction of the heating network to ensure citizens enjoy stable indoor conditions.
In 2009, the project won the honorable “Global District Energy Climate Award” issued by IEA in Copenhagen.

District Cooling System

While cool air brings much comfort to the residents of the subtropical city, the heavy use of electricity to run air conditioning systems is in fact taking a toll on the air quality. More energy-efficient air-cooling methods stand to bring remarkable improvements to our health and wellbeing.

Veolia Solution

First-of-its-kind District Cooling System in Hong Kong

Veolia has designed, built and operated the Kai Tak District Cooling System (DCS). The facility uses seawater as a cooling medium to produce chilled water to consumer buildings in the Kai Tak District, to replacing traditional decentralised air-conditioning systems in the consumer buildings. Chilled water travels through an underground water distribution network to provide green cooling to an non-domestic air-conditioning area spanning 1.7 million m2 and consisting of offices, schools, MTR stations, shopping mall, hospital and Cruise Terminal.
