Within the Roadmaps for Energy (R4E) project the partners will work together to develop a new type of energy strategy through visions and roadmaps for the 8 partner cities, in co-creation with local stakeholders. The stakeholders include the benefactors of the strategy, such as citizens, as well as relevant research and industry partners, to offer a clear picture of the future potential of the city. In the R4E project a four step process is applied. The FIRST step sets the ambitions for the project. The ambitions of the participating cities on sustainable energy and Smart Cities in general are set, as well as the partner cities' choice for 2 focus areas within Smart Energy Savings: 1.Smart Buildings, 2. Smart Mobility or 3. Smart Urban Spaces. The SECOND step is to develop desired scenarios for the cities for the selected focus areas. During the THIRD step the roadmap will be created, existing and future technologies and other developments will be identified, which enable the realization of the desired future scenarios. Opportunities and developments will be plotted on a timeline to provide insight in the required steps and milestones towards the favoured scenarios. The roadmaps will contain generic parts that are common for the partner cities, as well as specific parts that cater for the specific context of the cities. During the final and FOURTH step a project portfolio will be generated with new projects and initiatives to reach the ambitions, visions and roadmaps of the cities. This portfolio provides an overview of individual and joint projects and includes a cross-city learning plan and a financial plan. At the end of the project each partner city will each have 2 future scenarios, 2 roadmaps and a portfolio of individual and joint projects to implement sustainable energy policies and measures. Also the visioning and roadmapping capacities within the municipalities are developed to spur future development and implementation of innovative energy solutions.

Heat Pump and solar appliances are the most social accepted residential Renewable Energy based energy systems. SunHorizon will demonstrate up to TRL 7 innovative and reliable Heat Pump solutions (thermal compression, adsorption, reversible) that acting properly coupled and managed with advanced solar panels (PV, Hybrid, thermal) can provide heating and cooling to residential and tertiary building with lower emissions, energy bills and fossil fuel dependency. A Cloud based functional monitoring platform will be realised in the project to be the “performance data mine” for the development of Data Driven/KPI oriented optimized algorithms and tools to predict maintenance, optimize the management towards maximisation of solar exploitation and give to the manufacturer inputs for new installation design, via an innovative “robust design under uncertainty approach” which aims to overcome classical H&C equipment oversizing due to safety factors . This monitoring platform will also drive smart end user interfaces that will be applied at building level to collect thermal comfort data towards a new end-user driven H&C control system. SunHorizon tools will be applicable not only to proposed solar coupled HPs, but to all H&C appliances towards a global increasing efficiency of EU H&C stock and its decarbonisation. 5 low emission H&C Technology packages (TPs) will be tested coupling HP and solar installation. SunHorizon aims to be a breakthrough demonstration to market project involving 21 partners and 8 demosites all around EU focusing its activities on “reducing system costs and improving performance as well as optimising existing technologies for H&C applications”. SunHorizon will be focused on three main research pillars interacting each other towards project objectives achievement, demonstration and replication: i) OPTIMIZED DESIGN, ENGINEERING AND MANUFACTURING OF SUNHORIZON TECHNOLOGIES ii) SMART FUNCTIONAL MONITORING FOR H&C,iii) KPI DRIVEN MANAGEMENT AND DEMONSTRATION.

The overall aim of Sav€ the Homes is to contribute to an increase of an annual renovation rate of > 5% by offering attractive OSS services to homeowners, managed and implemented by municipalities as being trustworthy entities for citizens. This is achieved by the implementation of OSS Citizen Hub concept, offering renovation offices, both as physical hubs and web-based virtual hubs at local level based on the concept of medium-sized cities and to maximize replicability, at national and EU level. Sav€ the Homes will: 1. Offer a full customers journey in 5 stops: - Stop 0 Onboarding - Stop 1 Design: Social design by co-creation with the homeowners - Stop 2 Elaboration: Organizing the financing, purchasing of renovation kits and the preparations for the construction of the renovation works - Stop 3 Construction: Realization of proven quality in interaction with homeowners and a peer-to-peer Renovation Community, as part of the Citizen Hub - Stop 4 In-use: Monitoring of total performances in practice for ensuring sustainable quality of building and user experience 2. Create strong networks and trustworthy partnerships with local actors in the whole chain 3. Create locally developed and organized financing and investment pipelines The integrated home renovation services will be established within already established OSS networks at the city (City of Rotterdam) and regional (Comunitat Valenciana) level in two EU countries, building upon existing energy targets and networks so far well established at the city levels where it brings a new method and mechanism on how to improve the existing interactions between the relevant organizations and stakeholders. It holistically connects renovation advisory, products and services, finance opportunities and legal advice with a building owner at a single point. By involving relevant EU umbrella organizations, the concept will be further promoted in other member states to come to a harmonized method applicable at EU level.

NewTREND seeks to improve the energy efficiency of the existing European building stock and to improve the current renovation rate by developing a new participatory integrated design methodology targeted to the energy retrofit of buildings and neighbourhoods, establishing energy performance as a key component of refurbishments. The methodology will foster collaboration among stakeholders in the value chain, engaging occupants and building users and supporting all the refurbishment phases through the whole life cycle of the renovation. The methodology will be supported by an online platform to ease collaborative design, which will play the role of exchanging information and facilitating dialogue between the different stakeholders involved in the retrofit process. It will store all the information useful to the design of the retrofit intervention in a cloud based interoperable data exchange server, i.e. the District Information Model server, which has the ability to and export multiple file formats thanks to semantic web technologies. A Data Manager tool will be developed to guide the designers in the data collection phase, which might be a complex task for retrofit projects where information and drawings are scattered or even not available. The NewTREND platform will be a tool for collaborative design allowing evaluation of different design options at both building and district level through dynamic simulations via a Simulation & Design Hub. Design options, including district schemes and shared renewables will be presented to the design team, together with available financing schemes and applicable business models, in a library which will build on lessons from past and ongoing R&D projects. The NewTREND methodology and tools will be validated in three real refurbishment projects in Hungary, Finland and Spain where the involvement of all the stakeholders in the design .process, will be evaluated and specific activities will be dedicated to inhabitants and users

GEOFIT is an integrated industrially driven action aimed at deployment of cost effective enhanced geothermal systems (EGS) on energy efficient building retrofitting. This entails the development technical development of innovative EGS and its components, namely, non-standard heat exchanger configurations, a novel hybrid heat pump and electrically driven compression heat pump systems and suite of heating and cooling components to be integrated with the novel GSHP concepts, all specially designed to applied in energy efficient retrofitting projects.
