In ZERO-PLUS, a comprehensive, cost-effective system for Net Zero Energy (NZE) settlements will be developed and implemented. The system will be composed of innovative solutions for the building envelope, for building energy generation and management, and for energy management at the settlement level. A reduction of operational energy usage to an average of 0-20 kWh/m2 per year (compared with the current average of 70-230 kWh/m2) will be achieved through a transition from single NZE buildings to NZE settlements, in which the energy loads and resources are optimally managed. A primary objective of the project will be to develop a system whose investment costs will be at least 16% lower than current costs. In order to reduce "balance of system" costs, an approach of mass customization will be employed. Mass produced technologies will be integrated in a system that is optimally designed according to the local climate and site of each project in which it is implemented. To this end, a structured process will be developed and applied for the integration, optimization and verification of the design. The project's work programme will ensure a rapid market uptake, within its four-year scope, of the innovative solutions that will be developed. These solutions will be implemented in four different demonstration projects throughout the EU, with varying climates and building types. The results of their implementation will be monitored, analyzed and disseminated. A comprehensive market analysis and business plan will support the commercial exploitation of the project's results. The project will be carried out by a consortium that includes universities, project owners, technology providers and organizations, which will closely collaborate in all the project's phases.

Buildings account for 40% of energy consumption and 36% of CO2 emissions in the EU. • Anerdgy has developed a roof edge building technology which combines local energy generation, building design options and roof edge functionality in just one modular system. Currently many flat roof buildings, which are renovated or new builds, face multiple challenges to be energetically upgraded – cost, functionality, aesthetics and the local energy generation have to be optimally combined by architects and building planners to achieve both the building owners’ & the regulatory goals. As of today it is very difficult to achieve and as a result, the potential of flat roof buildings are very often not utilised. • The Anerdgy WindRail C30 System enables architects & building planners to overcome the flat roof challenges in an easy way for both planning & installation by the use of our multifunctional system on roof edges. The system combines the maximum possible renewable local energy generation with great aesthetics and cost savings. • The system is fully customizable for the various roof geometries and their needs. • The WindRail C30 system takes over many of the functions of traditional separately installed elements thereby typically recovering 35-70% of its cost whilst additionally enabling easy integration of design options. The remaining 30-65% of the costs is repaid by the local energy generation with a typical energy production cost of 0.05-0.10€/kWh. • The WindRail C30 system unlocks the immense potential of flat roof buildings, resulting in a by far better solution to achieve the goals of renewable local energy generation and CO2 reduction than with the current standalone solutions. Reports by the EU funded IEE project Episcope looking at European countries show that on average 11% of the buildings have flat roofs. A market review from Uni. St. Gallen indicate an addressable market size of 2.3 billion € per year. • WindRail C30 can tap this hitherto huge untapped market

PROBONO brings together a European multidisciplinary consortium of 47 partners, construction and consulting entities, public asset service managers, municipalities, technology solution providers and experts, to turn the six European districts (PROBONO´s Living Labs) into Green Building Neighborhoods (GBN), with positive energy balance and zero carbon emissions: two large-scale demonstrators (Madrid and Dublin) and four living labs representing business/owner promoters of the green buildings and neighborhoods’ transition (Porto, Brussels, Aarhus, Prague). PROBONO will provide strong examples of how GBN's technological and social innovations can be applied, with a vision focused on building infrastructure and a renewed focus on people and sustainability, taking full advantage of digitalization and smart technologies for the benefit of society. The adoption of the PROBONO approach and innovations will be proposed through a range of participatory methods that promote stakeholders (including citizens) partaking in co-designing and co-delivering a sustainable GBN. PROBONO will provide GBN Strategic Planning Tools in spatial, economic, technical, environmental regulatory, and social context aligned with city and urban masterplans and policy frameworks. PROBONO will create evidence-based policy recommendations, standardization actions, and robust adoption and commercialization strategies supported by a capacity-building program and a European Alliance of GBN Innovation Clusters. PROBONO will provide a GBN Digital Twin (DT) implemented across the LLs as a virtual representation of associated GBN including operational assets that implicate environmental and efficiency KPI. A cloud-based decision support-planning tool will be created to develop an optimized design for carbon-neutral energy GBN systems incorporating PROBONO innovative solutions on GBN demand and response dynamics. The technological developments will include metering different utilities with electricity, gas, warm energy, cold energy, and water linked to Smart IoT gateway and Energy Optimisation middleware, all this combined with geothermal, PV, micro-turbines, efficient HVAC technologies, green roofs, custom insulation, and GB energy optimization, efficient energy storage and integrating EV charging value chain. To enhance wide-scale adoption and standard creation, PROBONO will contribute with evidence-based policy recommendations, standardization actions, and robust adoption and commercialization strategies.

The innovative aspect in Pro-GET-OnE (Proactive synergy for Greater Efficiency On buildings’ Envelopes) consists in the following holistic vision: To combine in a same integrated system based on pre-assembled components the highest performances (iii) in terms of i) Energy requirements – by adding (or substituting the existing with) new prefab and plug and play high energy performing envelopes ii) Safety – by using appropriate steel structures to reduce horizontal loads and implementing the structural safety while supporting the new envelopes (timber for opaque parts/surfaces, glass, PV and solar panels) iii) Social sustainability – by ensuring tailored and customized solutions for users and increase the desirability of retrofit options. Building upon the previous experiences, Pro-GET-OnE aims at promoting a holistic optimized approach that goes beyond the results of EU and national projects and the IEA report on Prefabricated Systems for Low Energy Renovation of Residential Buildings. In fact, PRO-GET-ONE proposes the highest transformation of the existing building’s shell with volumetric increase and buffer zones (i.e. sunspace between the building and the outdoor environment, extra room, etc.). These solutions have been designed and analysed in a large set of existing buildings. Being the openings guaranteed, this solution would efficiently provide an effective zone to reduce thermal losses in the cold winter season while ensuring shadow during summer.
