District energy

District energy is a generic term for the central production and distribution of thermal energy for heating and/or cooling residential, commercial and institutional buildings, and for industrial processes. District energy systems have a number of overall benefits, including improved energy efficiency, enhanced environmental protection, ease of operation and maintenance as well as reliability, comfort and superior convenience for consumers.

District energy comprises three main elements:
  • A central energy plant that produces thermal energy. The central plant may also incorporate combined heat and power (CHP) plants.
  • A network of pre-insulated pipes to distribute the thermal energy from the central plant to buildings.
  • The interface with services at the building including space heating, domestic hot water services, cooling and process heat.

Ramboll offers a full range of services on district energy projects from feasibility studies and planning to follow-up on operation and maintenance.

Our specialists in district energy, waste-to-energy, CHP, renewable energy and building installations work closely together to provide optimal use of heating and cooling sources.

Feature article about district heating

Until now, no waste-to-energy plant in Denmark has used heat pumps to boost flue gas condensation and recover heat. No one believed it could be done cost-effectively, but the design team at Ramboll Energy had other ideas.
