European projects focusing on sustainable heating and cooling

The Heat Roadmap Europe project is mapping and modelling the heating and energy systems of the 14 largest users of heat in the EU, to develop new policies at the local, national, and EU level to ensure the uptake of efficient, sustainable, and affordable heating and cooling solutions. These 14 countries cover 85-90% of the heating and cooling demands in Europe!


THERMOS (Thermal Energy Resource Modelling and Optimisation System) is an EU Horizon 2020 funded research project that will develop the methods, data, and tools to enable public authorities and other stakeholders to undertake more sophisticated thermal energy system planning, far more rapidly and cheaply than they can today.


The ReUseHeat project will showcase replicable models enabling the recovery and reuse of excess heat available at the urban level, with the aim to increase the energy efficiency of district heating and cooling systems in cities across Europe.


The project “Low Temperature District Heating for the Baltic Sea Region” (LowTEMP) will make the district heating supply in the partner regions more sustainable and promote the installation of so-called 4th generation district heating networks. These systems are characterised by the transfer of lower temperature heat in optimally insulated pipes with reduced pipe dimensions. At the same time, multiple heat supply options are possible in these systems, i.e. the use of waste heat from industrial processes as well as renewable heat sources like geothermal and solar-thermal.




The project aims to showcase how District Heating systems can be more resource efficient and more energy efficient. COOL DH is designed to innovate, demonstrate, evaluate and disseminate technological solutions needed to use sources of very low-grade waste heat for heating of energy efficient buildings via Low Temperature District Heating (LTDH).



PLANHEAT will develop and validate an integrated and easy-to-use tool to support local authorities in selecting, simulating and comparing alternative low carbon and economically sustainable scenarios for heating and cooling. It will be validated in the three PLANHEAT cities.


The overarching goal of Hotmaps is the development of an open source heating / cooling mapping and planning toolbox and to provide default data for EU28 at national and local level. These data and tool allow public authorities to identify, analyse, model and map resources and solutions to supply energy needs within their territory of responsibility in a resource and cost efficient way. Those results will help authorities to develop heating and cooling strategies on local, regional and national scale which are in line with RES and CO2-Emission targets on national and EU level.



The progRESsHEAT project (March 2015- October 2017) assisted local, regional, national and EU political leaders in developing policy and strategies to ensure a quick and efficient deployment of renewables in heating and cooling networks. All project resources (local strategy development process, national analyses, policy recommendations, training materials, webinars and event reports) are available on the website.




SDHp2m stands for Solar District Heating (SDH) and actions from Policy to Market. The project addresses market uptake challenges for a wider use of district heating and cooling systems (DHC) with high shares of RES, specifically, the action focuses on the use of large-scale solar thermal plants combined with other RES in DHC systems.


Tempo develops technical innovations that enable district heating networks to operate at lower temperatures and make them suitable for a sustainable energy system. The project aims to combine individual technologies into solution packages for dedicated application areas covering 90% of the European district heating market. TEMPO further seeks to empower consumers through digital solutions and will develop new business models.




HeatNet will address the challenge of reducing CO2 emissions in North West Europe by creating an integrated transnational NWE approach to the supply of renewable and low carbon heat (incl. waste heat) to residential and commercial buildings. District Heating and Cooling facilitate energy efficiency, less CO2 emissions and a greener economy.


The RES H/C SPREAD project was aimed at developing six pilot regional plans for heating and cooling from renewable energy that could further support the planning efforts of other regions. It involved six regions – Castilla y Leon (Spain), Emilia Romagna (Italy), Riga (Latvia), Rhodope (Bulgaria), Western Macedonia (Greece) and Salzburg (Austria) – representing the main EU climatic zones, most of which are in the Mediterranean. Special attention has been devoted to improving participatory governance, enabling the cooperation of local, regional and national stakeholders. To this end, each region has established its own country governance committee to support the development and implementation of the plans.


LowUP – which stands for ‘Low valued energy sources UPgrading for buildings and industry uses’– will contribute to achieving Europe’s GHG reduction targets and increase energy efficiency. The project will develop and demonstrate three new efficient heating and cooling technologies that will significantly reduce both CO2 emissions and primary energy consumption.



The CE-HEAT project aims to improve the governance of energy efficiency by focusing on the field of waste heat utilization in Central Europe space and through increased exploitation of endogenous RES – waste heat. This field was identified as one of the most pressing issues at the regional and local scale – with little success in the past. At the same time, the waste heat utilization is recognized as important issue in the latest Energy Efficiency Directive (2012/27/EU). In order to improve governance in waste heat utilization, better and comprehensive planning, but also monitoring tools are needed.


 Large quantities of waste heat are continuously rejected from industries. Most of this waste energy, however, is of low-quality and is not practical or economical to recover it with current technologies. The Indus3Es project will develop an innovative Absorption Heat Transformer (AHT) for this purpose, focused on low temperature waste heat recovery (below 130ºC, referred to a recovered waste heat source temperature). The Indus3Es System will effectively recover and revalorize almost 50% of the low temperature waste heat, increasing quality of the waste source to the required temperature and reusing it again in the industrial process.



BERTIM will develop a prefabricated solution which will provide the opportunity to renovate improving energy performance, air quality, aesthetics, comfort, and property value at the same time while ensuring low intrusiveness during renovation works.



The main objective of TASIO project is to develop solutions dealing with the development of Waste Heat Recovery Systems (WHRS) based on the Organic Rankine Cycle (ORC) technology.

These solutions are able to recover the waste heat produced in energetic intensive (EII) processes of industrial sectors such as cement, glass, steelmaking and petrochemical and transform it into useful energy for internal or external use.
