lowtemp-logo-kompilacijaIn order to contribute to a reduction of energy waste and greenhouse gas emissions in the Baltic Sea Region (BSR), energy supply systems in all countries need to become much more efficient. Thereby, district heating (DH) infrastructures play an important role, but currently, existing DH systems do not comply with increased energy efficiency standards and often are technically outdated. Therefore, they need to be upgraded and technology has to change, i.e. present DH systems must undergo a change towards low temperature DH networks, upplying heat to new low energy buildings, but also to the existing building stock that has been or will be refurbished.

Low temperature district heating (LTDH) is a possibility to optimise existing DH systems or to develop independent future sustainable grids. By lowering the temperature, a reduction of heat losses and the utilisation of renewable energy and waste-to-heat sources are possible.

Within the LowTEMP project, partners from nine BSR countries come together, representing local and regional public authorities, DH providers, energy agencies, research institutions and national associations representing the energy and DH sector. Together they aim to make the DH supply in their municipalities or regions, but also on a broader scale in other BSR regions, more sustainable by integrating LTDH solutions.

Project specific objective is to increase energy efficiency based on enhanced capacity of public and private actors involved in energy planning. The first objective of the LowTEMP project is to increase the knowhow and competences within the project partnership. Secondly, LowTEMP aims to jointly collect and analyse data and information and then develop, knowledge pools, guidelines, strategies and tools that constitute the basis for the planning, installation and management of LTDH systems. The third aim of LowTEMP is to apply and disseminate the developed know-how and the project outputs, i.e. pilot energy strategies, proof of LTDH sustainability and financial strategies that support the implementation and management of LTDH systems, to broader target groups outside the partnership via a training programme and connected dissemination measures.
