EVENT will develop, demonstrate and validate a cost effective, high energy efficient, low CO2 emissions, replicable, low intrusive, systemic approach for retrofitting of residential and commercial buildings, able to achieve NZEB retrofit standard levels, through the integration of an innovative adaptive ventilated façade system, including: • Embedded, breakthrough smart modular heat recovery units, which allow thermal storage mode • High efficient photovoltaic generation capability units • Cost-effective, easy to install, high performance adapted products for external thermal insulation • Energy efficient HVAC systems The developed technologies will be integrated in the ventilated façade, and a real time intelligent façade management system will control operation of the system based on meteorological prediction methods for forecasting in advance the decentralised electricity production and the energy (electrical and thermal) demand of the building enabling maximum RE usage. It will inter-operate with existing or latest state-of-the-art Building Energy Management System, to achieve optimum energy efficiency by reducing primary energy needs, CO2 emissions and peak loads, assuring at least the same comfort levels required by Member States Building Codes, at an affordable price. Foreseen impact will be: • Energy savings of more than 40%, by the holistic use of the ventilated façade, the heat recovery of ventilation air • At least a reduction of 40% of CO2 emissions, as a consequence of the achieved primary energy savings • Reduced thermal and electrical peak loads • Typical performance target of less than 25 kWh/m 2 year (excluding appliances) Use of heat recovery units, number of photovoltaic cells, natural lighting strategies, and insulation thickness; are variable depending on the characteristics of the building to be retrofitted. Therefore EVENT retrofitting system can be adaptable to different types of buildings and climates, which makes the system versatile.

Conventional Retrofitting (CR) can result in high energy use reductions at the expense of high installation costs and, usually, without being able to directly perform harvesting from Renewable Energy Sources (RES). Building Automation (BA) systems, as compared to CR, can result in medium energy use reductions and in low or medium harvesting from RES at the expense of medium installation costs and medium operational costs. Recently, the concept of Adaptable/Dynamic Building Envelopes (ADBE) - such as Multifunctional Façade Modules - has been proposed towards overcoming many of the shortcomings of CR and BA. ADBE systems can result in high energy use reductions and high harvesting from RES at the expense of medium-to-high installation costs and medium operational costs. The main strategic goal of the PLUG-N-HARVEST proposal is to design, develop, demonstrate and exploit a new modular, plug-n-play concept/product for ADBE - deployable to both residential and non-residential buildings - which is able to provide high (maximum possible) energy use reductions and high (maximum possible) energy harvesting from RES both at the single-building and the district scale while requiring medium-to-low installation costs and almost-zero operational costs. Moreover, by appropriately exploiting its attributes, the PLUG-N-HARVEST system will be designed and implemented considering circular economy principles, which will allow implementing new business models based on leasing and renting modes and, by this, leaving the door open to massive implementations. Four different multi-building Pilots – in Germany, Spain, Greece and the U.K. - will be used for demonstrating the use of the integrated PLUG-N-HARVEST system in full-scale, on a 24/7 basis and for a long period. The Pilots involve buildings with all different kinds of energetic, thermal and occupants' interactions, home occupants of highly diverse behaviour and background and include both residential and non-residential buildings.

PLURAL aims to design validate and demonstrate a palette of versatile, adaptable, scalable, off-site prefabricated plug and play facades accounting for user needs (“Plug-and-Use” kits). Three different core systems are assessed, coupling heating-cooling, ventilation, heat harvesting systems with smart windows, 3D printing, low carbon footprint and nano-enabled coating materials to reduce the building total primary energy consumption to less than 60 kWh/m2 per year and ensure on-site renewable energy generation to more than 50 kWh/m2 reaching NZEB status for different European climates and different residential building typologies. A BIM based big data management platform and a Decision Support Tool (DST) are coupled to enable the optimal component selection, and integration, best PnU kit design, speedy and low-cost manufacturing and installation. Renewable energy and smart control systems are coupled with low environmental footprint prefabricated façade components to create the integrated all-in-one PnU kits for post war residential building deep renovation. The project creates best practice renovation examples for the residential sector based on innovation and competitiveness, with benefits for the citizens and the environment. It develops business cases and models for key stakeholders and improves the life cycle based performance standards applied in the building sector. The solutions are implemented in three real and three virtual residential buildings to evaluate reduction in renovation time and costs, the PnU kit performance, carbon saving and users’ acceptance. The selected buildings cover all European climatic zones and are representative residential typologies. PLURAL will achieve at least 50% reduction in the time required for deep renovation of e.g. multi-family blocks. 58% reduction in renovation costs will be achieved through off-site prefabrication lean manufacturing and construction, interactively supported by the BIM based platform and DST.

Europe has witnessed a significant rise in the frequency and severity of extreme weather events, and especially the broader Mediterranean region showcases the devastating consequences of climate-related disruptions. CLIMRES aims to foster a ‘Leadership foEurope has witnessed a significant rise in the frequency and severity of extreme weather events, and especially the broader Mediterranean region showcases the devastating consequences of climate-related disruptions. Unseasonably warm temperatures during the winter months are increasingly becoming a pattern, disrupting traditional weather patterns and ecosystems. CLIMRES aims to foster a ‘Leadership for Climate Resilient Buildings’, by addressing the identification and systematic categorisation of buildings’ vulnerabilities and estimating their impact in the buildings' ecosystem considering the interlinkages within the urban context. The project will deliver vulnerability assessment and impact evaluation methodologies along with an inventory hub of measures for building materials and design against climate risks and a decision support toolkit addressing three levels of decision making at strategic, tactical and operational levels. CLIMRES solutions will be tested in 3 large scale pilots in Spain, Greece, Italy and Slovenia evaluating their efficacy against heatwaves, extreme flooding, fires and earthquakes and one multi-hazard replication multiplier pilot in France. The experiences and lessons learnt from the extensive pilot evaluation will consult the replication roadmap of the project as well as a capacity building programme that will train the next frontier leaders for climate resilient buildings. Overall, the CLIMRES Leadership will provide valuable insights and guidance for building owners, policymakers, and stakeholders involved in building climate resilience and sustainable development, through the co-creation, development, deployment and demonstration at TRL 6-8 highly cost-effective and replicable solutions.
