Description of the Technology

This methodology describes the main steps to create energy strategies and provides guidelines for efficient district heating system implementation with lower temperatures in the distribution networks. The methodology provides specific working steps for energy planners in municipalities on how to compile an energy strategy. This includes area analysis, stocks evaluations (buildings, density, supply, energy demand), potentials for increasing energy efficiency and diminishing consumption, resolving the technical preconditions and requirements of district heating, profitability assessment etc.

The DH development strategy should be developed in close cooperation with the municipality and relevant stakeholders as there are steps that cannot be implemented without the support of a heat supplier or DH network operator. Nevertheless, the municipality has an important role in the transformation process as it has the necessary tools to ensure legislative framework, identify long term goals for a particular area and ensure communication between heat suppliers, developers, consumers and other interested parties.  


Development of low-temperature climate neutrality heat supply strategy applicable to heat supply system long-term development planning by identifying main tasks and objectives for the future energy sector.


The low-temperature heat supply strategy allows planning long-term development scenarios, making well-thought-out investments and systemic development of the urban environment, identifying synergies between energy efficiency in buildings and district heating in buildings. Lowering the temperature of the networks contributes to the reduction of transmission heat losses and more efficient use of renewable energy sources.
