Project Reports

The following page is going to include all published reports on survey and analysis results, guidelines and handbooks as well as learning material produced in this project.


Policy framework conditions assessment and outlook for sustainable heating and cooling in selected European regions – Report D2.1

The following report deals with an overview of policy strategies, measures and instruments related to heating and cooling (HC) equipment. It identifies the main drivers and barriers, and presents success stories of HC replacement projects/instruments in each project region which can potentially be replicated.


Making heating and cooling sustainable – barriers, solutions and best practices – Report D2.2

The focus of this analysis lies on legal aspects that impede the market acceptance of renewable heating and cooling systems. The barriers, their causes and consequences are the main topic of this report.


Survey on existing demand-response (DR) actions and collective actions in the heating and cooling sector and overview of legal and other requirements and challenges – Report D2.3

This report provides information on the status quo of Collective Actions (CAs), Renewable Energy Communities (RECs) and Citizens’ Energy Communities (CECs). Altogether, 19 demand-response actions and 28 examples for collective actions in the REPLACE target countries are shown.


Exchange of experience with previous replacement campaigns and their embedding in policy programms, SWOT of facilitating policy measures – Report D2.4

Report D2.4 shows an in-depth overview of the work that has already been done on national and local level in order to replace inefficient heating and cooling systems. It includes 22 campaigns for the promotion of heating and cooling equipment that had taken place inside the REPLACE regions, plus five more campaigns that occurred outside the target regions.


Inventories of the mind-sets and needs of all relevant stakeholders in the target regions – Report D3.1

Report D3.1 shows the socio-economic motives and mind-sets of REPLACE’s key stakeholders, their perceptions, attitudes and motives in respect to sustainable heating and cooling. The survey’s focus in the nine pilot regions was on heating and cooling equipment replacement issues, market conditions and observations and on related collective actions. Investors additionally were asked about heat supply models and demand response related activities. 


Statistical inventories of the heating systems market and development scenarios in the target regions – Report D3.2

This report reflects the status and transition from the use of fossil fuels and inefficient heating and cooling systems for residential buildings to cleaner and more environmentally friendly alternatives in ten EU regions. It describes the impact of the REPLACE project in the number of boilers and homes replacing old inefficient systems by new sustainable ones, as well as the energy savings, CO2 emissions reduction and level of investment triggered.


Heating-matrices showing recommended RES heating technologies fitting to various building types & qualities – Report D4.1

The heating matrices in this report provide an initial overview of which heating system based on renewable (non- fossil) energy sources or district heat is most suitable for a building. The matrices presented, starting from the Austrian “klimaaktiv” blueprints, were adapted regionally with regard to structural and environmental conditions, building standards and economic viability. 


Renewable heating & cooling replacement handbook for end consumers – Report D4.2

In order to support consumers in making the right replacement choice, this report provides a practical guide to end-users who are considering replacing their heating system or undertaking an energy efficiency measure in their home. The report gives useful information on the economic, environmental and social benefits, it advises on the steps that should be taken before and during the replacement process and answers the most common questions that end-users ask in this context. Finally, the report presents a comprehensive list of the renewable heating and cooling technologies currently available on the European market.


Best Practice Examples of (R)HC Replacements in the Target Regions – Report D4.4

In order to persuade consumers of the benefits of innovative low-carbon and renewable heating and cooling systems, the illustration of best practice examples is an excellent tool to show how replacements can be implemented under real local conditions, being at the same time technically and economically feasible.

This report shows real life testimonies of 38 end-users and building occupants who have recently replaced their old inefficient heating system with a greener solution, which provides both economic and environmental benefits. Three cases from each of the project’s target regions, plus eight innovative best practice examples from more experienced countries (Austria, Germany and Spain), are presented and cover a variety of solutions and approaches, ranging from residential building refurbishment and (R)HC replacement to demand-response and collective consumers actions.


Action plans for boiler & oven replacement campaigns in ten pilot regions – Report D6.1

REPLACE aims to boost the phase-out of inefficient and old heating and cooling systems. The project implements replacement campaigns, which include activities that shall inform consumers about sustainable heating solutions and motivate them to replace their fossil fuelled or any old, inefficient heating systems.

Report D6.1 contains tailor-made action plans for each pilot region. The action plans define specific activities/measures, time-frame, involved stakeholders and all other necessary details for actual implementation. In addition, local media cooperation strategies for promoting the replacement campaign are part of the action plans.



Handbook heating replacement – For installers, chimney sweeps and investors

For climate friendly replacements of heating and cooling systems to be successful, the commitment of intermediaries and investors is as necessary as the involvement of end users.

This report aims therefore at providing professional intermediaries (such as installers, chimney sweepers, building developers, energy advisors, etc.) with in-depth knowledge of the renewable heating and cooling systems options available on the market today, with the objective of making them well-trained facilitators of replacements and of enabling them to measure and communicate expected energy and financial savings and wider societal benefits of heating and cooling replacements.


At the same time, the report informs investors (either financing institutions, public authorities, energy suppliers, or homeowners) about economic issues, best practices and innovative business models, as well as model contracts, for renewable heating and cooling solutions.
