RenoZEB aims to unlock the nZEB renovation market leveraging the gain on property value through a new systemic approach to retrofitting that will include innovative components, processes and decision making methodologies to guide all value-chain actors in the nZEB building renovation process; including integrated solutions with highest impact in the revalorization of the building. This will be achieved through: (a) Development of an innovative holistic, cost-effective and fast deep retrofitting methodology fornZEB. (b)Supporting the methodology for nZEB renovation, through ICT tools. (c) Development of a cost-effective and non-intrusive prefabricated multifunctional modular “plug and play” system for the renovation of buildings, (d) Increasing the post-retrofitting property value, through the transformation of buildings into an Active Energy. (e)Nodes through a smart control & monitoring system (f) New collaborative multi-value, multi-stakeholder methodologies and decision making process for selecting the best energy efficient renovation strategy. (g) Creation of new drivers of change for the Real Estate Industry creating fresh post-renovated property value schemes. (h) Demonstration to the Market of the Replicability of the Holistic Methodology and New Technologies through. (i) Three Virtual Demonstration sites. (j) Boosting the NZEB market through training and awareness of the value chain. RenoZEB addresses all the relevant aspects from the call, but also many of the issues expressed in the work programme. RenoZEB will provide cost-effective plug&play solutions for a large scale deep NZEB rehabilitation schemes, ensuring the integrability of all its components, methodologies, training, guidelines, and demonstration cases (real and virtual) that show and ensure the replicability of the schemes, and technical tools to appropriately address the valorization of the building stock before and after nZEB renovation schemes are applied.

Tertiary sector buildings sector consume a sizeable proportion of EU total energy consumption and the majority of consumption is directly attributed to the operational phase of the building life-cycle. Occupant behaviour is a major cause of this consumption. OrbEEt proposes an ICT-based framework to induce behaviour change toward energy efficiency by transforming energy measurements into personalized feedback delivered through engaging user interfaces. To achieve this challenge, OrbEEt foresees dynamic, spatially fine-grained extensions of building-level Operational Rating methodologies and Display Energy Certificates to provide a detailed view of energy use in office spaces, business processes and organizational entities rather than entire buildings. The fusion of information from Building Information Models, Business Process Models and real-time energy use measurement via a comprehensive ICT cloud service - the Systemic Enterprise Operational Rating framework - will enable energy use tracking and will establish direct accountability of people, processes and spaces toward overall consumption. Exposing the direct influence of occupant behaviour on energy use enables the design and successful deployment of behavioural change campaigns in public organization buildings. OrbEEt proposes interventions appealing to intrinsic/extrinsic human motivators through intra-organization social competitions and organization-wide social collaboration endeavours. The OrbEEt framework and behavioural change interventions will undergo real-life pilot validation in four EU public buildings that provide the business, cultural and geographical diversity for demonstration of result effectiveness and transferability. Finally, the OrbEEt consortium will use a User Driven Innovation Approach throughout its development, deployment and validation of phases to leverage and actively support Open Innovation and the EU Cleanweb/start-up community toward further exploitation of its outcomes.

ENSNARE’s main objective is to boost the implementation of renovation packages through (1) the digitalisation of the entire process by means of a digital platform and (2) the development of an industrialised envelope mesh enabling fast assembly and interconnection of passive and multifunctional building components. The methodology and tools provided will facilitate the necessary market uptake of novel and highly efficient solutions for nZEB, accelerating the current retrofitting rate and supporting the transformation of the European building stock into a highly efficient and technologically advanced built environment. Within a comprehensive systemic approach, the project will target the development of modular adaptable components to be integrated within the system (rather than marketed as standalone products that increase the cost and complexity of the system), including an active window for ventilation and heat recovery, solar harvesting devices (thermal collectors, PV and hybrid panels with advanced technologies such as roll-bonding), heat pumps and energy batteries for load shifting. The digital platform will comprise a set of digital tools supporting and accelerating all stages for a more efficient renovation process: automated data acquisition, LCA/LCC analysis and decision support, digital BIM model building and computer-assisted manufacturing (CAM), and a smart building management system (sBMS) for optimised operation and maintenance. All these tools are linked to a digital model, which increases in complexity and interaction potentialities as the project develops. At completion, the model becomes a Digital Twin of the renovated building allowing real-time monitorization, simulation and optimised operation of all building components. The ENSNARE solution will be validated through three pilot renovation projects covering Nordic, Continental and Mediterranean climates, and three virtual demonstration buildings aimed at upscaling the development of the solution.

Heat4Cool proposes an innovative, efficient and cost-effective solution to optimize the integration of a set of rehabilitation systems in order to meet the net-zero energy standards. The project develops, integrates and demonstrates an easy to install and highly energy efficient solution for building retrofitting that begins from the Heat4Cool advanced decision-making tool (which addresses the building and district characteristics) and leads to the optimal solution combining (1) gas and solar thermally driven adsorption heat pumps, which permits the full integration with existing natural gas boilers to ensure efficient use of current equipment , (2) solar PV assisted DC powered heat pump connected to an advanced modular PCM heat and cold storage system, and (3) energy recovery from sewage water with high performance heat exchangers. This retrofitting solution together with a closer interaction between building monitoring, demand/respond supply match, weather forecast and HVAC activation/control through a Self-Correcting Intelligent Building Energy Management Systems (SCI-BEMS) will save at least 10% of energy consumption. The project will implement four benchmark retrofitting projects in four different European climates to achieve a reduction of at least 20% in energy consumption in a technically, socially, and financially feasible manner and demonstrate a return on investment of 8 years. The Heat4Cool consortium will ensure the maximum replication potential of the Heat4Cool solution by a continuous monitoring of technical and economic barriers during the development and validation phases in order to present the building owners and investors with clear energy and economic evidence of the value of implementing Heat4Cool solution. A detailed business plan will be developed in the beginning of the project to strengthen the exploitation plan of the retrofitting package and set the basis for a massive replication of the demonstrated concept across Europe.
