District heating and cooling

District heating and cooling (DHC) is an integrative technology that can make significant contributions to reducing carbon dioxide emissions and air pollution while increasing energy security. A district heating network is a system that supplies the heat generated in a centralized plant to meet residential and commercial space and water heating requirements. A district heating scheme comprises a network of insulated pipes used to deliver heat, in the form of hot water or steam, from the point of generation to the end user.

District heating networks transport heat efficiently. Currently, they can be built in a distance of up to around 30 km from a generating plant and the distribution networks themselves can be hundreds of kilometres long. This is sufficient to distribute heat across cities, smaller communities and industrial areas. A network can easily be extended by simply adding more heat sources along the way. With respect to cooling, the DHC concept is implemented either through the distribution of chilled water or by using the district heating network to deliver heat for individual heat-driven chillers. DHC networks can distribute energy from various sources and integrate large scale storage while enabling the connection of several users, especially new buildings and refurbished buildings, with a decrease in the energy consumption of the district. 

List of projects where this technology is being implemented.

FLEXYNETS

FLEXYNETS will develop, demonstrate and deploy a new generation of intelligent district heating and cooling (DHC) networks that reduce energy transportation losses by working at “neutral” (15-20°C) temperature levels. Reversible heat pumps will be used to exchange heat with the DHC network on the...

PITAGORAS

The PITAGORAS project focuses on the efficient integration of city districts with industrial parks through smart thermal grids. Technologies and concepts for low and medium temperature waste heat recovery, considering as well integration with renewable energy sources (RES), and heat (and power)...

SINFONIA

The SINFONIA project is a five-year initiative to deploy large-scale, integrated and scalable energy solutions in mid-sized European cities. At the heart of the initiative is a unique cooperation between the cities of Bolzano (Italy) and Innsbruck (Austria), working hand in hand to achieve 40% to...

SCHOOL OF THE FUTURE

The aim of the School of the Future project was to design, demonstrate, evaluate and communicate shining examples of how to achieve the high performance building of the future. School buildings and their primary users - pupils - were the focus of the project. Both the energy and indoor environment...

REMOURBAN

REMOURBAN is a lighthouse project whose ultimate goal is to design and validate a urban regeneration model in the cities of Nottingham (United Kingdom), Valladolid (Spain) and Tepebasi/Eskisehir (Turkey), while maximizing its replication potential in two follower cities, Seraing (Belgium) and...

SmartEnCity Site Tartu

Tartu has around 100,000 citizens and it is a compact university city. It provides a very good development environment, to a great extent due to its proactive city government. Demanding cross-sectorial cooperation is well established in Tartu, and it has internationally competitive R&D...

CELSIUS Site Cologne

In order to create a district-wide energy network in Cologne, Active Network Management (ANM) integrates decentralised energy generation and district heating systems with the electricity distribution network. The objective of the ANM scheme is to inform the models that are used to assess if...

CELSIUS Site Genoa

Genoa Municipality’s objectives include education and solidarity, quality of life, energy efficiency strategies, economy and employment, communication and promotion of the city, port and infrastructure, city management improvement. The Municipality of Genoa is one of the first cities in Italy to...

CELSIUS Site Gothenburg

In Gothenburg a large amount of waste heat, from both waste incineration and industries, is used in the district heating system. There is also heat pumps taking care of the heat in sewage and plants using bio fuels such as wood pellets, wood chips and bio oil. There is also a district cooling ...
