The EXCESS project builds up on nearly-zero energy multi-storey building (consumption below primary energy threshold) residential concepts of the main 4 EU climatic zones towards Energy fleXible user-CEntric poSitive houseS (EXCESS). EXCESS defines a positive energy building (PEB) as a building that produces more energy than they use, with high RES self- consumption rate (instead of using the grid for solving seasonal balancing issues) over a time span of one year. RES and smart technologies exist, but complete packages for different climates do not. Important technical developments for plus energy building materials and other individual technologies are required to address specific climate related needs in order to meet the PEB level; especially in harsh climates. Integration is needed for upgrading single technologies to be part of a large orchestra enabling also user-context-aware energy flexible services between utilities and customers (selling flexibility). These will unlock additional revenue streams that reduce the lifetime cost of the developed PEB solutions, making them affordable also large portion of the society. Thus, EXCESS will advance new materials, technologies and integrated technological systems (TRL5-7) promoting a user centric approach (building tenants), capitalized on new ICT opportunities, for optimizing the interplay of local generation, storage, consumption at the building and district level. The demonstration activities in each of the climatic zones (Austria, Belgium, Finland and Spain) will be accompanied by co-innovation, replication and exploitation activities to maximize the project technical, social and economic impact and to prepare for a future market roll out of the PEB concept by also scouting energy efficiency funding opportunities.

InterConnect envisages to contribute for the democratization of efficient energy management, through a flexible and interoperable ecosystem where demand side flexibility can be soundly integrated with effective benefits to end-users. In fact, over the last few years several projects and technology providers have come up with solutions that allow every energy user to have awareness and control over his appliances, but there has always been a major issue with interoperability. End-users should be able to choose and change their technology providers, without having to replace their installation, every time they feel this need and still be able to adopt sustainable behaviour and benefit from technological advances. In the energy sector, a steep move towards digital is occurring and becoming tremendously user-centric and market-driven. The system dimension is significant, as the number of energy service providers is increasing thanks to favourable regulatory environment and technology advancements for monitoring and control. This is the reason why this consortium integrates relevant partners from all the representative stakeholders in this new energy paradigm. Specific competences in ICT, IoT, energy, data science, software, were included and the full value chain, from R&D institutions, manufacturers, DSO, retailers, IT providers, and energy users is represented. To guarantee a higher Europe-wide impact, several relevant associations related with ICT and energy are also involved. To achieve a significant dimension, 7 large scale pilots, in different countries and with different end-users, are foreseen to guarantee representativeness and dimension in terms of number of appliances and services. The overarching objective of these pilots is to demonstrate a real digital market environment over electrical systems with significant amounts of DSF, reducing operational and investment costs that will benefit energy end-users and help EU achieve its energy efficiency objectives.
