City-wide district heating systems and in general District Energy Systems are the key to cost-effective use of environmentally friendly, low-carbon heat sources. Ramboll is among the world’s leading consultancies for the planning, implementation and operation of these city-wide systems with experience from more than 25 countries.

Our district heating departments work closely together with our departments for waste-to-energy, CHP and renewable energy and buildings to make optimal use of our multidisciplinary approach. Our services include all stages of planning, design, operation, maintenance and management, and include technical, institutional, legal as well as economic aspects of the work.

Carefully planned and optimized in combination with individual solutions, a district heating system with a storage tank or a large inter-seasonnal pit storage is a cost-effective and efficient solution in urban areas. It is a precondition for efficient use of carbon neutral or low-carbon heat sources, such as:

• heat from CHP plants
• waste-to-energy plants
• biomass CHP plants
• geothermal plants
• biomass boilers
• large-scale heat pumps using surplus heat or any thermal resource
• large-scale heat pumps in combination with district cooling (trigeneration)
• electric boilers to utilize fluctuating wind energy
• and large-scale solar thermal plants.

Even for small communities, district heating with a thermal storage can be the answer to the demand for cost-effective and carbon neutral heating for both existing and new buildings.
