EVELIXIA brings together 36 high profile organizations from 12 EU countries envisioning to realize Buildings as Active Utility Nodes (BAUNs), rendering the EU Building stock as: a) energy efficient; b) connected, by facilitating a two-way communication between the grid and the occupants, capitalizing on flexible technologies; c) smart, by utilizing analytics supported by sensors and controls to co-optimize efficiency, flexibility, and occupant preferences; and d) flexible, reducing, shifting, or modulating energy use according to occupant needs, while considering utility signals. EVELIXIA structures the advancement of its solutions along five Innovation Pathways: IP1: Building-to-Grid (B2G) Services; IP2: Grid-to-Building (G2B) Services; IP3: Human-to-Building Interfaces & Interactivity; IP 4: Systems Interoperability; and IP5: Innovative HW as Flexibility Enablers, which will be integrated, deployed, and validated at 7 large-scale, real-life pilots (GR, RO, FR, FI, ES, AT, DK). During the EVELIXIA platform deployment and validation, different actors (i.e., DSOs, DNOs, ESCOs, aggregators) from various sectors (electricity, heating/cooling, mobility) will exchange data for providing B2G and G2B services and they will participate in the development of Business Models showcasing the economic viability of the solutions proposed. EVELIXIA puts a large focus on social engagement empowering citizens as not only adopters of solutions, but also, as their co-creators applying methodologies for citizen and consumer engagement and advanced human to building interfaces. Key expected outcomes include: 14 scalable B2G/G2B services demonstrated including DSF (implicit, explicit, shifting, etc.), P2P energy trading, portfolio management (day ahead/intra-day), TSO/DSO/DHO, and system planning services; GHG emissions reduced by 17%, increase of flexibility by up to 25%, increase of self-consumption up to 100%, reduce energy consumption by 13.5%, and increase RE generation by 11%.

CHRONICLE will deliver a holistic, life-cycle performance assessment framework and tool-suite for different building variants, supporting sustainable design, construction and/or efficient renovation and investment decision making. It will be methodologically integrate ongoing initiatives, like EPCs, Level(s), SRI, under the umbrella of the Digital Building Logbook concept. Performance will be assessed by means of well-defined KPIs, based on both static (by design) as well as dynamic information (sensor measurements) appropriately tailored to different types of use and building life-cycle phases (new or existing buildings under refurbishment). Continuous monitoring and analysis of the actual building performance over its lifetime, will be based on a powerful digital twin framework. The proposed data availability and accessibility within CHRONICLE will extend the limits of the EU energy related policies while the aggregated EPC advanced information will facilitate efficient energy planning. To this end, CHRONICLE will allow all stakeholders to realize in quantified terms the short- and long-term impact of the project activities, from policy to practice, and across the whole building life cycle. It will therefore promote evidence-based impact assessment practices to support policy coherence, design of smart penalties and reward schemes towards motivating energy consciousness, while also paying attention to the voice of market stakeholders (AECs, ESCOs, FMs) but also building owners and tenants/occupants, who are directly impacted by future regulatory decisions. CHRONICLE’s building performance assessment framework and tool-set will be demonstrated and validated in five pilot sites spanning the geographic diversity of Europe, namely in Spain, Ireland, Denmark, Greece and Switzerland.

Digitisation in existing buildings is not as widespread as in other sectors. A consequence is that buildings owners and occupants have generally a limited understanding of their building as an energy system. Improving the energy efficiency of existing buildings can and should be achieved through deep renovation. In comparison, smart technologies can increase the efficiency and the flexibility of buildings in a shorter term and with much less investments. The domOS project addresses the smart building sector through two axes. In the first axis, technology, guidelines for an open, secure, multi-service Internet of Things (IoT) ecosystem for smart buildings are defined: in-building gateways, which connect to local smart devices and smart appliance of any type, IoT platforms and applications operated by different parties can be integrated seamlessly. Buildings owners can enforce privacy rules, they can allow / forbid access to any measurement or control point. The second axis deals with the development of smart services. They increase energy efficiency of space heating (heat pumps, district heating, gas boilers) thanks to innovative control algorithms making use of smart sensors and smart heating appliances. Automated advice services provide concise and sound information on the building energy. Buildings become active nodes of an electricity grid or a District Heating grid. These two axes are present in each of the five demonstration sites of the domOS project: The Sion (CH) and Paris (F) pilots test smart services related to electricity. In Aalborg (DK), control techniques applied to space heating for buildings connected to a Distributed Heating grid reduces consumption and lower costs, CO$_{2}$ emissions and system load. In the Neuchâtel (CH) and Skive (DK) demonstrators, closed-loop control minimises temperature at the output of the heating system, thus increasing efficiency and reducing losses.

The aim of the SERENE project is to develop and demonstrate sustainable, integrated, cost-effective and customer-centric solutions for local communities. The idea is to integrate different energy system carriers and new renewable generation units in the local communities based on their social and technical status today to meet their energy needs in the coming years. The users has to be involved in the changes of the energy system and be informed about different technical opportunities and business cases to make decisions about their participation. Depending on the actual site, the new energy system involve different storage technologies (battery energy storages, heat storages, water storage-systems), demand response systems to enhance the flexibility of the systems (activating for instance electric vehicle charging stations and heat demand supplies), electric transportation systems like electrical vehicles or buses, heating system improvements using heat-pumps and integration of new renewable generation sources mainly in form of photo voltaics. The SERENE project will establish demonstrations in local villages in three European countries - Denmark, The Netherlands and Poland. The experiences gained at the demonstration sites will be analyzed and evaluated for replicability in firstly Europe but also world wide. Technical benchmark models and solutions will be set up together with their business models, and it is evaluated how different legal aspects form the involved countries will affect the possibility for replication. Further, the needed user involvement and their interest to join are evaluated seen from both geographic, social, environmental and economic conditions and characteristics.

The overall purpose of the SUSTENANCE project is to set up sustainable energy systems for achieving novel carbon neutral energy communities. The project focus on the development of smart technological concepts ensuring a green transition of the energy systems with higher share of local renewable energy and more efficient integrated energy solutions for the electrical, heat, water, waste as well as transportation infrastructure. The set up solutions will at the same time have good socio-economic impact in the local communities and ensure ecofriendly solutions and good infrastructures, which provides support to sustaining the essentials of life. The demonstration activities are set up in four countries: Denmark, India, Netherlands and Poland. These countries has different local energy resources, socio-economic, user behavior, political structures, market conditions and regulations. The project will show how same technical concepts such as coupling of different energy vectors, storage solutions, demand response, intelligent control schemes and digitalization can be applied to all demonstration cases despite the huge differences in the local conditions and regulations. Road maps will be set up based on these technical solutions together with guidelines for methods for user engagement and ensuring cooperation among the users in relevant cases leading to cooperatives. Finally, business cases will be set up for the different demonstration sites seen from both user perspective, small enterprises and utility point of view taking into account the local conditions. In this way, synergy effects with inputs from the different demonstration sites are expected and the results give abundant possibilities for maximum impact and replication in other local communities in the four countries as well as in societies worldwide.
