Supporting accelerated and cost-effective deep renovation of buildings through Public Private Partnership (EeB PPP) Proposals should demonstrate and promote innovative processes leading in practice to more cost-effective, higher quality, holistic and faster deep renovation of buildings with less disturbance of the residents. Proposals should demonstrate the contribution to an increased rate of renovation in a specific district/city/region. The building renovations may use pre-fabricated mass manufactured components or ""plug and play"" energy and ventilation systems, including innovations needed during the on-site phase. Proposals should consider innovative integrated packages of commercially available technologies. This typically includes actions on the building envelope and on the technical building systems both including renewable energy sources and conversion and storage technologies, in order to achieve very high energy performance. The proposals could include specific solutions for historic buildings, when applicable. Means of sharing technical information on the building over its whole life cycle could also be considered[[The use of BIM (Building Information Modelling) for documenting and sharing technical information on the building over its whole life cycle.]]. Proposals should ensure that the solutions guarantee high indoor environmental quality (thermal and visual comfort, acoustics, air quality, etc.). If necessary proposals should include smart controls to allow integration with the energy grid. Embodied energy and the possibility of reusing and recycling materials at the end of a building's life are highly relevant to the building's overall life cycle, therefore these aspects should also be taken into account.Solutions should demonstrate the integration potential of innovative processes and explore how they could facilitate renovation. Proposals could make use of geo-clusters[[Geo-cluster is understood as a group of districts, cities, regions or large areas of the EU (may be even covering several MS) with similar characteristics, e.g. climate, building typology, technology, market barriers, etc.]] to respond to specific needs and to demonstrate the potential for replication.Synergies may be considered with activities initiated under the topic LCE-17-2017.The Commission considers that proposals requesting a contribution from the EU of between EUR 3 and 4 million would allow this specific challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts.This topic will be implemented under the PPP on Energy-efficient Buildings. The activities are expected to be implemented at Technology Readiness Level (TRL) 6-8 (please see part G of the General Annexes). Proposers should note that this topic is also complemented by other topics relating to deep renovation, including in the PPP on Energy Efficient Buildings. Too much of Europe's building stock is inefficient in terms of energy use, with excessive heat losses through building envelopes and technical building systems. In addition, buildings need to contribute a greater share of renewable energy production. Too few buildings are undergoing deep renovation (whereby energy savings exceed 60% compared to pre-renovation levels) and such renovations are often too expensive. There is a need to demonstrate more cost-effective and practical ways of achieving deep renovation while reducing the time needed to renovate a building and at the same time promoting a holistic optimized approach that goes beyond the results of European and national projects, and the IEA report on Prefabricated Systems for Low Energy Renovation of Residential Buildings. Proposals are expected to demonstrate the impacts listed below, using quantified indicators and targets wherever possible: Net primary energy use reduced by 60% compared to pre-renovation levels; Cost reduction of at least 15% compared with a typical renovation (i.e. a renovation that meets current minimum requirements of existing building regulations[[Definition of typical renovation is based on each country’s implementation of Art. 4 of the EPBD]]); Demonstration of the effectiveness of the proposed solutions to reach an increased rate of renovation of a defined building typology in a specific district/city/region. Reduction in time needed for renovation by a factor of 2 at least compared to typical present day renovation.
