INTRODUCTION Within the RES-DHC project, stakeholders in the 6 pilot areas will foster the market development for renewables in district heating and cooling networks. For reaching this objective, they could also benefit from a number of already existing tools on the topic of DHC (District Heating and Cooling) by RES (Renewable Energy Sources), often developed within the framework of other European projects. Therefore, one of the RES-DHC activities is the collection and systematisation of these tools, which are listed and described in this document. The choice of the tools to be included in this deliverable was made basing on different criteria: - Specific tools related to RES-DHC and not more general tools, for example on energy plan-ning. - A wide variety of typologies for the tools, such as planning, design, policy, training, etc. - Different categories of target groups (policy makers, professionals, district heating sector, etc.). - Suggestions from RES-DHC project partners. - Specific needs and requests by the RES-DHC pilot areas, also discussed within the Regional Stakeholder Advisory Groups. - Preferably non-commercial tools. Regarding the last point, commercial tools which can be useful for working on RES by DHC were anyway summarised in the Appendix. 2.

TOOL 1: POTENTIAL FOR RENEWABLE HEATING AND COOLING (ENTRAIN) The tool at a glance Within the framework of the ENTRAIN project, supported under the Interreg Central Europe pro-gramme, specific guidelines were prepared for assessing the potential for exploiting renewable en-ergy sources for heating and cooling, with a special focus on district heating networks. The scope of such a potential assessment could be at different scales: local, regional or even national. The tool is available for free here. Figure 1: Front cover of the guidelines Tool description The potential guidelines aim at supporting, and at the same time motivating, potential stakeholders and local communities to seek better and more efficient solutions to meet local heat demand. The purpose is not to provide a comprehensive methodology for performing a detailed assessment but rather to give an overview of the necessary information prior to deciding on the investments and initiating projects. 6 For each one of the key topics of the guidelines (heat demand, heat supply, external aspects), the main questions which should be answered for carrying out a good potential analysis are presented, together with a list of tools and references, collected from a number of projects and publications. Figure 2: The basic scheme of the guidelines A thorough analysis of energy supply and demand in the targeted area lays the foundation for further planning of renewable DH system. Initial energy balance in the targeted areas helps to identify the needs of the communities, as well as to evaluate potential solutions to the current state. Therefore, guidelines for determining heat demand and supply are given as the primary steps of such evalua-tion. In the heat demand step, additional attention is given to the territorial aspect of the target area, i.e. climate of the area, urbanisation, industrial areas, which all provide important elements to consider when planning the DH systems. Heat supply step provides an overview of the locally available re-newable energy sources (biomass, solar heat, geothermal, waste heat and heat pumps) each with a set of questions, which can help determine the potential for each in the target region. Finally, the last step of the evaluation is combining the inputs and insights gathered in the two pre-vious phases in order to reach some conclusions on the potential for using DH from renewables in the target area. The reader may also be interested in having a look at the potential reports, also developed within ENTRAIN, on the renewable heat potential in the 5 pilot areas in the project (in DE, HR, IT, PL and SI). The reports are available here, under the ‘TARGET REGIONS’ section. Target groups This tool is mainly addressing public administrations at different levels, such as Municipalities, Re-gions, Provinces, National Ministries, etc. Furthermore, it could be used by local stakeholders (for example DH project developers) for as-sessing the DH potential at a smaller scale (urban regeneration for a single district or block, heat supply for a small suburb, etc.). 7 4. TOOL 2: COUNTRY HEAT MAPS AND ATLASES (HEAT ROADMAP EUROPE) The tool at a glance The Horizon 2020 funded Heat Roadmap Europe project developed a set of tools basically divided into two main sections: - An interactive map providing a variety of resources for heat planning in 18 EU countries. - A Pan-European Thermal Atlas reporting, for 14 EU countries, the heat demand density for performing potential analysis. The tools are available for free here. Figure 3: A screenshot of the interactive map Tool description This set of tools was developed mainly within the Heat Roadmap Europe project, supported within the Horizon 2020 programme. The goal is to provide stakeholders, especially at national level, with useful resources to evaluate the potential for renewable district heating and cooling as well as to create strategies for market development. The main difference with the previous tool, therefore, is the wider scope of the analy-sis, shifting from the local or regional scale to the national level. First of all, the set of tools includes an interactive map with a variety of resources related to 18 EU countries: Atlases, maps, country presentations, roadmaps and other sources of information useful for heat planning (see, in the screenshot below, the example for Italy on the list of the available resources). 8 Figure 4: An example: The list of resources available for Italy The second part of the set is a Pan-European Thermal Atlas (PETA), now available in its 4.3 version here. This atlas reports, for the 14 EU countries included in the analysis, heat density maps. Although the resolution is 100 m grid size, the atlas authors warn that the confidence level of the actual values on this scale is too low. Therefore, when looking at small scales, the heat demand figures can be only indicative, while a better level of confidence can be expected for larger resolutions, for example 1 km. Figure 5: A screenshot of PETA4 9 Finally, a version 5.1 of the PETA was also developed containing, at the moment, preliminary data which are subject to validation. Target groups Given the scale of the available data and of the analysis, the Heat Roadmap Europe set of tools is mainly targeting key stakeholders of the district heating market operating at national level, therefore including, for example, Ministries, associations of DH operators, networks of cities and regions, etc. 10 5. TOOL 3: ONLINE PACKAGE FOR VIRTUAL STUDY TOURS (ENTRAIN) The tool at a glance This tool, developed within the ENTRAIN project, offers an online collection of videos, from all over Europe, on district heating and cooling networks run on renewable energies. The tool is available for free here. Figure 6: Partial screenshot of the webpage on virtual study tours 11 Tool description The idea of this virtual package was born soon after the COVID-19 pandemic, since this sudden emergency prevents many projects, initiatives and single DH operators from welcoming visitors and arranging study tours. It includes, at the moment, 10 examples in Europe of district heating systems using different solutions with renewables, namely solar thermal, biomass, waste heat, etc. The videos usually report not only the technical details of the heating plant and of the connected network but also the story of how the project was initiated, which where the barriers to be overcome, the opportunities to be exploited, etc. The number of available videos, however, will constantly grow since the package is being continu-ously updated. In many cases, furthermore, you can hear directly from the stakeholders involved in the project, such as DH utilities, Mayors of the Municipalities, citizens as users of the system, etc. The videos are published in different languages but, since they are all available on YouTube, auto-matic English subtitles can be easily added just by clicking on the image to open the video and then, on the YouTube video, by clicking on "settings", selecting "subtitles" > "automatic translation" and finally selecting the English language. Target groups The virtual package is addressing all stakeholders who want to learn about how renewables are used in practice for supplying district heating and cooling systems. Therefore, the targeted recipients belong to a wide variety of actors: Mayors and other representa-tives of Municipalities, Regions and other Public Authorities, district heating utilities and experts, renewable energy professionals, consumer associations, environmental NGOs, etc. 12 6. TOOL 4: ECONOMICS OF HEAT PUMPS IN DISTRICT HEATING The tool at a glance This tool, developed by the Danish Energy Agency, allows to perform an initial and simple calculation of the economics of electrically driven heat pump projects in district heating. The original tool in Danish is available for free here. Within the RES-DHC project, the Excel spread-sheet was translated in English and coupled with a short document summarising the instructions for filling in the sheet. Figure 7: Partial screenshot of the tool spreadsheet Tool description In connection with the document "Guide to large heat pump projects in district heating", the Danish Energy Agency also developed a spreadsheet-based tool, which can be used for a simple calculation of the economics of electrically driven heat pump projects in district heating. First of all, it should be stressed that the actual economics of a project may differ significantly from the tool outcomes. It should be used, therefore, only at an initial stage of a project and the calculated results should always be validated through other studies before being used for investment decisions. The spreadsheet, developed in Microsoft Excel, consists of one tab. It is recommended to zoom the spreadsheet so that the whole tab can be seen on the screen. The purpose of the spreadsheet is to calculate the cost-effectiveness of a heat pump project in an already existing heating plant, which can consist of up to four different production units, one of which is a solar heating plant. 13 The calculation is based on user-based inputs in the 35 sand-coloured cells on the left side of the user interface. The calculation results are shown in the four graphs on the right side of the interface, as well as in the light blue tables. Figure 8: Graphs and tables showing the calculation results It is recommended that, before calculating a project example through this tool, the user read carefully all the details reported in the document “Spreadsheets instructions for simple heat pump calcula-tions“. Target groups Due to the expertise and competencies needed to fill in the spreadsheet correctly, this calculation tool is mainly addressing technical actors dealing with district heating as, for example, utilities or technical personnel of Local Authorities in charge of a first evaluation of the economic feasibility of a project. 14 7. TOOL 5: OPEN SOURCE TOOL FOR MAPPING AND PLANNING OF ENERGY SYSTEMS (HOTMAPS) The tool at a glance The HotMaps project developed a toolbox to support interested stakeholders in strategic heating and cooling planning at local, regional and national levels, in line with European energy policies. The toolbox is accessible for free here. Figure 9: The concept of the HotMaps toolbox Tool description The HotMaps toolbox is an open source software, for studying the integration of RES in DH by providing datasets, as well as tools for estimating demand reduction scenarios and analysing dis-patch and related performance indicators for various supply portfolios under different conditions. Another feature of this tool is that it is user-driven since it was developed, within the HotMaps project, in collaboration with 7 pilot areas. Furthermore, the scope of the tool is very wide, being applicable to all cities and other areas in EU-27 + the UK. The tool provides the users with a large array of open source data sets for EU-27 countries + the UK, including many different layers, such as energy supply sources (geothermal, solar thermal, mu-nicipal solid waste, etc.), load profiles (residential loads for both space heating and domestic hot water, industrial energy needs, etc.), economic information (fuel costs, technology costs, electricy price scenarios, etc.), etc. 15 Figure 10: Screenshot of the tool in use HotMaps also features a DH dispatch model available in three different versions. This model, acces-sible in the online browser tool via the “Calculation Modules” button, allows to look into the details of the demand side and to perform hourly-based calculation. It is possible to project the future heat demand based on scientific data on demographic and energy efficiency effects. It is also suitable for studies and analyses on both sector coupling and temperature levels in the DH networks. Figure 11: The HotMaps district heating dispatch model Target groups The key beneficiaries of this tool are the main actors in strategic heating and cooling planning, namely public authorities at different levels, energy agencies and planners, as well as other inter-ested and relevant stakeholders, such as district heating and renewable energy associations. While some features such as the heat demand and potential analyses are simple to use, the calcu-lation modules require more skilled knowledge of the topic. 16 8. TOOL 6: QUALITY MANAGEMENT SYSTEM FOR RENEWABLE DISTRICT HEATING (ENTRAIN) The tool at a glance The application of the quality management system “QM Heizwerke” can allow a more efficient reali-sation and operation of DH systems, thus ensuring a better quality of the service and low heat prices for the consumers. All the details on this tool are available here, under the “QM TOOLBOX” section. Figure 12: Screenshot of the “QM TOOLBOX” Tool description The QM system was born as a quality management system, known as “QM Holzheizwerke”, as a collaboration between Austria, Germany and Switzerland to improve the quality of district heating systems run on biomass. Later, thanks to the work done within the ENTRAIN project, the key documents and tools of the QM systems were translated first in English and then in the national languages of the project pilot areas in (Croatian, Italian, Polish and Slovenian). One more action, carried out within the ENTRAIN framework, was the extension of the quality system from biomass only to all the potential renewable energy sources, including the recovery of waste heat, which can be used to feed DH systems. Compliance with the QM system allows to reach several key objectives at the same time, namely reliable and low-maintenance operation, precise and stable system control, highest possible degree 17 of utilisation and low distribution losses, low emissions in all operating states and, finally, ecological and economic sustainability. The QM TOOLBOX, freely available online, includes several documents and spreadsheets in Eng-lish: The QM guidelines (describing the process and the quality requirements), the economic profit-ability calculation tool, two different tools for estimating heat losses, an information sheet on meas-urement equipment and, finally, a QM informative leaflet describing the key features and benefits of this quality system. Figure 13: The Italian page of the QM system, run by the energy agency of Friuli-Venezia Giulia Target groups The QM system aims at reaching two different group of stakeholders, depending on the phase of its application. As a matter of fact, such a system could really help in improving the quality of the DH sector at national or regional level and, therefore, it could be introduced as a compulsory system or as a voluntary one, possibly linked to the granting of incentives for the realisation of a new DH system (as well as for its extension or revamping), as happens at the moment for example in Austria. From this point of view, then, the target groups of this tool are the national or regional authorities regulating the sector and the related incentives (regulatory bodies, Ministries, regional administrations, energy agencies, etc.). Once in use, then, the system targets mainly technical subjects in charge of developing DH project, such as technical managers of the utilities, designers and planners of biomass heating systems, etc. 18 9. TOOL 7: SOLAR DISTRICT HEATING – PLANT DATABASE The tool at a glance This database presents the basic data for several solar district heating plants in many different coun-tries. The tool is accessible for free here. Figure 14: A screenshot of a part of the database Tool description The database includes basic information on 195 solar district heating plants in operation in many different countries. The set of data includes: Name of the plant, year of operation start, owner, Coun-try, city, aperture area of the solar collector field (in m2) and thermal capacity (in kWth). The database can be downloaded as both a sheet (CSV or Excel) or a pdf file. Target groups The database is especially targeting technical stakeholders, such as researchers, technical person-nel of Municipalities, utilities, ESCOs, engineering companies and single professionals. 19 10. TOOL 8: PERFORMANCE ASSESSMENT OF DHC SYSTEMS (WEDISTRICT) The tool at a glance This tool is rather a methodology, summarised in a detailed scientific paper, for calculating different DHC key performance indicators (KPIs), distinguishing between heating and cooling ones. The paper is described and downloadable for free here. Figure 15: Heat fluxes in the proposed methodology Tool description1 The assessment of a DHC system is challenging when the same equipment or system elements are used for purposes of producing heating and cooling, either simultaneously or alternatively. This is particularly the case for complex systems, which involve different energy sources and technologies in a single district energy system. Many components of such a system may be used for both heating and cooling: Reversible heat pumps, heat generation or recovery applied to thermally driven cooling technologies, geothermal probes coupled with ground source heat pumps, photovoltaics, etc. Moreover, a growing endeavour of energy vector coupling, including renewable heat, electricity, green hydrogen, and syngas, is go-ing to lead to even more complex district energy systems. As for now, there is no comprehensive methodology for performance analysis of combined DHC systems. This paper, therefore, proposes a methodology for calculating different DHC key perfor-mance indicators (KPIs), distinguishing between heating and cooling ones. A total of 11 indicators 1 Text slightly edited from the original one, available at https://www.wedistrict.eu/new-publication-performance-assess-ment-of-district-energy-systems-with-common-elements-for-heating-and-cooling/ 20 are organised under four categories: Energy, environment, economy and socio-economy. The meth-odology proposes demand-based and investment-based share factors that facilitate the heating and cooling KPI calculation. Target groups Given its very technical and scientific approach, this tool / paper is addressing researchers working on DHC and technical personnel of the utilities. However, as a second priority, this methodology for DHC performance evaluation could be also used in support schemes managed by local, regional and national authorities and, therefore, though indi-rectly, they could also be regarded as target groups of this tool. 21 11. TOOL 9: THERMOS SOFTWARE The tool at a glance This free online tool aims at helping to accelerate the decarbonisation of heating and cooling net-works by supporting engineers, planners and other actors to create and optimise low-carbon heating and cooling solutions. The geographical scope of the tool is worldwide. The tool is accessible for free here. Figure 16: The software logo Tool description2 THERMOS has been developed by the EU-funded project by the same name. The project software version (version 8) is freely available as an open-source code. THERMOS main features include: - Network optimisation model for identifying a cost-optimal network design; Users can estimate energy output or cost over time through different demand profiles and tariffs. - OpenStreetMap for easy map creation and analysis or the possibility to upload own GIS data. - Tool for generating heat and cold maps. - Demand estimation method operating with limited data input in any location. - Representation of variable pipe and dig costs and network heat losses. - Incorporation of capital costs for plant, pipes and connection, set against revenues from heat sales and monetised emissions. - Interoperability with GIS formats for model results and map export. - Nearly comprehensive documentation of data requirements and model operation. - Network supply model, for a more detailed modelling of the heat supply. 2 Text slightly edited from the original one, available at https://www.thermos-project.eu/thermos-tool/tool-access/ 22 Target groups The THERMOS software has, as first target group, technical actors in the field of DHC, such as planners, utilities and university researchers. Figure 17: A video tutorial of THERMOS 23 12. TOOL 10: SOLAR DISTRICT HEATING IN CITIES The tool at a glance These guidelines describe the implementation of solar district heating integrated in existing district heating systems in cities. This tool, therefore, is not including all renewable energy sources in DHC but it rather focuses on solar thermal only. The document is downloadable here, searching in the database for “SDH in cities”. Alternatively, the English version of the guidelines is directly accessible here. Tool description3 The manual describes the steps for integrating medium and large-scale solar thermal plants in ex-isting district heating (SDH) systems in cities. Figure 18: The cover of the SDH guidelines When starting SDH projects in existing district heating there are two key problems. The first one is that the summer load, that is when the solar output is higher, is normally already produced by the utility through power production or other sources of excess heat. 3 Text slightly edited from the document introduction. 24 The second barrier is that it is often difficult and sometimes expensive to find areas where to place the solar collectors. Of course, that does not mean that it is impossible to integrate SDH in cities, especially because more and more cities want to change their heat supply from fossil fuels to RES. In order to reach this goal, for instance, DHC systems often need to have thermal storages in place and, in that case, large SDH plants can play a role, as they are one of the cheapest heating technologies. These guidelines are divided into development steps following the decision-making process. After each step, a decision has to be made by the process stakeholders whether or not to continue the process, basing this decision on economic, social and logistic parameters. Target groups This manual is targeting both technical actors and decision makers such as, for example, managers of utilities, policy makers at the local, regional and national levels, planners, etc. 25 13.

INTRODUCTION The RES-DHC project — Renewable Energy Sources in the District Heating and Cooling sector, kicked off in October 2020 focuses on increasing the share of renewable energy in district heating and cooling systems across Europe. Eight countries (Germany, Switzerland, Austria, Italy, France, Poland and Denmark) as well as the European umbrella organisation EuroHeat & Power, based in Brussels, Belgium have joined forces to drive the decarbonisation of the DHC sector. The project started with surveys at regional level to analyse the current market situation as well as barriers and opportunities to the development of renewable district heating. The next step is to use this knowledge to develop concrete and detailed action plans to promote renewable district heating. The point is to propose an adaptive methodology for developing regional market development strategies and planning the corresponding actions. The methodology presented in this document should bring support in the development of strategies that are adapted to the identified barriers, feasible and efficient. However, the process proposed is flexible to make sure that all regional par-ticularities can be taken into account. 3 2. PROCESS DESCRIPTION The process is divided in four steps. Each step is further detailed below. However, it is important to note that the result is not final. Step four takes place after implementation start: the action plan should be continuously and regularly updated to take into account new developments and concretise the actions further. This process should be undergone taking into account the ideas and opinions of relevant market actors. In the RES-DHC project, Stakeholder Advisory Groups composed of relevant market actors at regional level have been set up. These groups should be involved, at least in step 1 and if possible, all along the process to consolidate the result and make sure that market actors endorse the defined strategy. However, we recommend to test the methodology in advance in a small group before moderating a larger event to the action plan.

STEP 1: FROM BARRIERS & OPPORTUNITIES TO MEASURES The aim of this step is to create a list of possible measures to tackle the barriers and make good use of the opportunities identified. Each barrier should be met with one or several concrete measures. This step should be dealt with in a “brainstorming” mind-set. No budget or limits should be taken into account at this stage. The only criteria is that the measures proposed should be adapted to the regional framework conditions. We recommend to involve market stakeholders at this stage to bring in a large diversity of points of view and ideas. A preliminary step consists in classifying the barriers. The type of barriers identified within the RES-DHC project are listed in Table 1: Types of barriers TYPE OF BARRIER DESCRIPTION LACK OF KNOWLEDGE A lack of information of the stakeholders is one of the most common bar-riers for renewable district heating. But it is often not expressed as such, especially if the list of barriers is made directly by the stakeholders. It is therefore important to identify if the know-how is available but not spread or if the issue has not been tackled yet. ECONOMICAL Economical barriers are also very common. In this case, the solutions exist and are well known but are not implemented because of economic feasibility criteria. LEGAL / POLITICAL The legal framework must be changed to tackle this barrier, or a change must occur at political level (i.e. new procedure, contracts etc.) TECHNICAL Technical barriers are very seldom and it is important to ensure that the solution is not already available, at least at international level. ORGANISATIONAL Organisational barriers concern communication between stakeholders as well as the organisation of the market sector in general. A selection of possible measures to overcome the identified barriers are listed below, according to the type of barrier. Basic measures Following basic measures are planned for all regions in the RES-DHC project and should be con-sidered for replicating regions: • Creation of a regional / national stakeholder group gathering market actors with regular meetings and exchanges • Setting-up an information point centralizing all resources on the topic (i.e. website) 5 Measures addressing a lack of knowledge / information The first point is to identify if the know-how is available at local level or not. If not, the scope should be broadened and the measure should consist in identifying external solutions, i.e., at international level and organizing exchanges: site visits, workshops, courses. Figure 2 shows the first steps to undergo in this case. If the know-how is available at local level but the information does not circulate, for example in the case of the legal framework or financing opportunities, an information campaign should be started. The priority is to identify the stakeholder group (municipalities, DH operators, etc.) and to decide on the best supports (see list in Figure 2). The main actors who can help to spread the information should be identified and involved. Measure addressing economical barriers Economical barriers can mostly be addressed by: - Finding and spreading the knowledge about possible sources for financing, innovative business models or quantifying the other advantages of renewable solutions - Lobbying for incentive taxes on fossil fuels or any other change in framework conditions able to improve the economical calculation (see measure addressing legal barriers). Countries where the solution is more widespread can be studied to understand the levers used for market development Measure addressing legal / political barriers Where is the know-how available? At international level At local level Organize exchange (site visits, workshops, courses etc.) Feasibility studies (For replication of the solutions at local level) Pilot projects (at local level) Best practice examples (at local level) Spread the know-how: - Workshops - Formation - Factsheets, articles, publications, guidelines, videos - Tools Figure 2: Matching barriers with adapted measures 6 If the barriers are specific to the legal or political framework and the issue cannot be addressed directly, the stakeholder group is very precious. Indeed, with the support of professional associations concerned, a position paper can be published to propose a list of framework modifications that would ensure faster market development. Local political representatives can also be addressed directly to explain the necessary changes and their advantages. Measure addressing technical barriers Identifying a technical barrier, the first question to answer is: is it really a technical issue or does the solution already exist but is not well-known? If the solution is already implemented somewhere, measures addressing a lack of knowledge should be implemented. If no solution was identified yet, a research project is an appropriate measure. Measure addressing organisational barriers The DH market sector is organized quite differently in each country and this has an important impact on the market developments. The necessary measures are therefore very specific to the local con-ditions but as a rule, enhancing communication between market actors to share good practices, setting common targets, developing quality criteria or labels, organizing the sector thanks to profes-sional associations or common innovation centers are efficient measures to promote market devel-opment of new solutions. 7 4. STEP 2: SETTING PRIORITIES The first step should have resulted in a list of possible measures for market devel-opment. The aim of this second step is to analyse each of the measures of the list in order to rate it and classify in a level of priority. 4.1. Evaluation chart An evaluation chart should be defined. An example is given in Table 2. Working groups should feel free to add criteria or change their weight according to their local circumstances. In this proposition, available resources is not a criteria for defining the priority of a measure. Measures with high priority but no funding or not enough resources available stay marked as high priority, even if the funding has to be found first (see 4.3). Table 2 : Example of evaluation chart Criteria Notation Comment Weight Time horizon of the impact Long-term 1 Mid-term 2 Short-term 3 Estimate how long the measure will take to be implemented and to show effects (ST 5 years) 20% Direct impact on the market Low 1 Average 2 High 3 For example: investment triggered, num-ber of plants taking action 30% Indirect im-pact on the market Low 1 Average 2 High 3 For example improvement of the quality level, know-how of stakeholders etc. A measure can have direct and indirect impact 20% Opportunity No 1 Unclear 2 Definitely 3 Is there a momentum around this topic at the moment or stakeholders ready to take action now? Is there a high public ac-ceptance? 30% The sum of the weights should add up to 100%. The weights are set here as an example. For ex-ample, in a country where the legislation will soon become very restrictive regarding fossil heating and measures with long-term impact might come too late, the weight of this criteria will be stronger than in countries where the efficiency of the measure could prevail over its rapidity of implementation. 4.2. Notation Each measure should be evaluated according to the evaluation chart defined. The more stakehold-ers participate in this step the better consolidated the result will be. Each criteria receives an average notation taking into account all votes. This average notation is then taken into account in the global evaluation with the corresponding weight. For example, if a group of stakeholders is asked to evaluate the following measure: “develop a CO2-neutral label for district heating networks”. Table 3 shows the result if three persons participate in the process and give the notes indicated in their column for one measure: 8 Table 3 : Example of votation and calculation of the global evaluation for the measure “develop a CO2-neutral label for district heating networks” Criteria Person 1 Person 2 Person 3 Average Comment Weight Time horizon of the impact 1 2 2 (1+2+2)/3 = 1.7 When will this label start to have an impact on the market? How long until customers are aware of it? (long-term is 1, mid-term is 2, short term is 3) 20% Direct impact on the market 1 1 1 (1+1+1)/3 = 1 Will this label directly trig-ger new projects or change of energy in exist-ing DH? (yes, a lot: 3, maybe but not sure: 2, probably not 1) 30% Indirect im-pact on the market 3 3 3 (3+3+3)/3 = 3 Will this label improve the quality, image, and com-munication within the sec-tor or towards customers? (yes, a lot: 3, maybe but not sure: 2, probably not 1) 20% Opportunity 3 3 2 (3+3+2)/3 = 2.7 Are there other projects dealing with the topic or is a tool already available that could be adapted? Is there an interested stake-holder in the group who is ready to support this ac-tion? (yes, clearly: 3, yes, but there are also a lot of barriers: 2, not really a topic at the moment: 1) 30% Total - - - = 1.7*0.2 +1*0.3 +3*0.2 +2.7*0.3 = 2.1 - 4.3. Classification The global evaluation for each measure should help sort the measures in three priority levels. The exact limits of those categories should be defined according to the local situation. For example, priority 1 for projects with a global evaluation over 2 points, priority 2 over 1.5 points and priority 3 below. If there are too many measures or too few in category 1 for instance, the limits should be set differently, or the reasons should be discussed with the participants. 9 Finally, measures implemented in category 1 should be sorted out between measures that can be implemented immediately because resources are available (budget, stakeholder interest, etc.) and the measures for which resources should still be acquired. At the end of the process, all measures from the initial list should be sorted into one of the following four categories: 1- Highest priority – immediate implementation 2- Highest priority – search for resources 3- Second priority 4- Low priority, to implement only in case an opportunity arises This prioritized list constitutes the regional strategy for market development ore renewable district heating solutions. Category 1 will be further detailed in an action plan. Funding or resources will be actively looked for regarding measures in category 2. Measures in the other categories should be documented also to be evaluated again further on. 10 5. STEP 3: ACTION PLAN Once the priorities have been defined, each one of the measures ranked 1 accord-ing to the previous step should be described in detail to enable implementation and monitoring of the impact. The description of each measure should contain following information: 1) General information: • Title of the measure • Short description • Date of the last update • Author 2) Detailed information: • Geographical localisation • Partners involved at local level • Description of the initial situation and addressed barriers • Addressed target group(s) • List of objectives • Detailed description of the implementation plan • Monitoring strategy for the impact The collection of these description constitutes the action plan for the region/country. As far as pos-sible, the measures should be endorsed by all partners involved in the implementation. For exam-ple, the action plan could be published presenting the logos of all partners involved. Within the RES-DHC project, action plans will be developed for each region involved. A summary report of the regional strategies and action plans will then be published and made available on www.res-dhc.com. 11 6. STEP 4: REGULAR UPDATE Two types of regular updates should be planned: 1) Update of the descriptions of measures Depending on the measure, a rhythm should be defined in the monitoring strategy for a regular update of the description, including a feedback on the impact of the measure and lessons learnt from the implementation. 2) Update of the action plan A regular update of the whole action plan, i.e. yearly, should be planned. The process should be repeated to take into account the evolution of framework conditions, check if the priorities are still valid or if new measures can be put in motion. This process results in the confirmation of the current action plan or its update. 7. CONCLUSION The proposed methodology should support market actors in their market development goals by help-ing to clarify their strategy, plan and monitor the implementation. Key success factors are the partic-ipation of experiences market actors, flexibility and adaptation of the methodology to the framework conditions and regular update of the results.
