As one of the world’s leading district heating consultancies, Ramboll has more than 30 years of experience from projects in more than 25 countries. Our services encompass all stages of planning, design, operation, maintenance and management; including technical, institutional, legal, as well as economic aspects. In recent years we have also actively engaged ourselves in several district cooling projects.
As cities aim to be carbon neutral, district heating and cooling systems become more important than ever. Our international market for these services is growing, not least due to a growing concern with climate change.
Hot water district heating
A city-wide, low-temperature hot water district heating system is key to any low-carbon city. The system is cost-effective and uses efficient, carbon neutral heat sources that would otherwise be wasted.
The heat sources derive from CHP plants with heat accumulators, waste-to-energy plants, geothermal plants, biomass boilers, large-scale heat pumps and large-scale solar heating plants.
Even for small settlements, district heating with thermal storage can be the key component of the most intelligent, cost-effective and carbon neutral heating for both existing and new buildings.
District heating steam and super-heated water
A special system for district heating, based on super-heated water or steam, is used mainly for industrial processes, but also in some cities and hospitals. Ramboll has extensive experience with these systems, including the design of pipe systems with a proven lifetime of more than 50 years. We also have experience in transforming these systems into more efficient, low-temperature systems.
Combined heat and power
At Ramboll, our great experience of energy production facilities based on a variety of fuels is combined with our experience of district heating transmission systems and low-temperature district heating systems. This helps us maximise the environmental, social and economic benefits for both investors and consumers.
We offer our clients all services that are necessary for establishing optimised CHP plants, heat accumulators and district heating systems – from planning, design and procurement to implementation.Our experience encompasses a wide range of CHP plants, including waste-to-energy, biogas and biomass plants.
Decentralised electric chillers in district cooling systems can often be replaced by less expensive systems that use cold seawater, groundwater or carbon-free thermal energy. Our experience in district cooling includes chilled water storage, district heating absorption heat pumps and decentralized cooling plants based on solar heating.

Heating installations in buildings
The efficiency of a city-wide heating system depends on its integration with low-temperature heating systems in buildings. We provide our clients with expertise in the design and operation of all facilities in the system, including building installations.

Hydraulic calculations and thermal analyses are prerequisites for correct dimensioning of utility supply networks, for new schemes as well as for expansion or renewal of existing networks. Ramboll has a team of engineers who perform hydraulic/thermal analysis on a daily basis for clients with large and small schemes for both district heating and district cooling networks.
Ramboll has developed a system for stationary and dynamic hydraulic/thermal calculations. Read about System Rornet.
Efficient operation and maintenance ensure high security of supply within the economic framework. Ramboll offers unique asset management consultancy based on a combination of expert knowledge of O&M theory and hands-on technical experience from district energy systems.
