If BIM is key to address the construction sector growing technical complexity, to overcome construction processes fragmentation and communication problems between stakeholders, to reduce on-site time and improve quality and affordability, its uptake for the renovation of the EU existing building stock is yet to come and already late. To face this BIM4REN starts from 3 workflows adapted to the construction sector segmentation (90% of companies are SMEs) presenting particular technical and organisational requirements and has adapted the project and consortium to provide adequate and innovative processes, methodologies, software and hardware tools & BIM developments for each one of them, backboned by state of the art BIM technologies like worldwide used BIM Server (open-source) and BIM Bots by TNO among many others. BIM4REN gathers together top European RTOs active in the Built Environment domain (Nobatek, CSTB, Tecnalia, TNO, Fraunhofer ISE) alongside key industrial actors (EDF, CMB Carpi & ATI Project (leading BIM implementers in the EU market) with 2 Universities (RWTH & Vilnius Gedimas) and up to 11 SMEs: R&D performing (R2M, Ekodenge), SME contractors (Kursaal) and technology providers (IES, EnerBIM, WiseBIM, VRM, AEC3, etc.) with the European Builders Confederation, the Green Building Council Italy and a large French Social Housing Organisation (Logirep) representing the whole residential renovation value chain. B4R digital ecosystem will be accessible via a web based One Stop Access Platform, where depending on each user profile and needs, orientation, best practice examples from a dedicated database and links to the different tools and services (from Top-grade to Entry-level) will be provided on differentiated access schemes underpinned by different business models. Inspired by the Open Innovation 2.0 paradigm the project will setup a demonstration campaign with “pilots as Living Labs” integrating all stakeholders in 3 cities (Paris, San Sebastian and Venice).

Built2Spec brings together a new and breakthrough set of technological advances for self-inspection and quality assurance that will be put into the hands of construction stakeholders to help meeting EU energy efficiency targets, new build standards, and related policy ambitions. B2S will expand upon a cloud based construction support platform, conceived following the most advanced integrated design and delivery framework for the building sector and hosting applications that facilitate worksite activities and quality compliance by putting knowledge in hands of contractors, in the form of shared design specifications and 3D models, installation guidelines, information on regulatory frameworks, and help from construction experts on smartphones and tablets. New self-inspection technologies managed within the platform and developed in the project include: • Special IR camera in smartphones coupled with new mathematical “reverse” models for on-the-fly analysis of existing buildings envelope thermal properties • Rapid BIM modelling via instant 3D capture with smartphones, passed via the cloud to the refurbishment team back-office, allowing accurate instant energy efficiency evaluation, quality check and streamlined quotation process • Portable, innovative low pressure air tightness technique allowing testing of occupied buildings • Smart sensor-embedded construction elements (identification, structural performance, and building environment parameters) • Portable single device for Indoor Air Quality tests offering multi-gas capabilities targeting the most harmful gas pollutants • A novel lightweight portable sound source for on-site acoustic tests to regulation compliance The B2S system will be integrated into the operations of SME contractors, large construction firms, and end user clients directly within the consortium and work program activities, assuring systematic and scientific performance measures, feedback and powerful exploitation and dissemination strategies.
