An approach to collect building sensors data based on Building Information Models. Pierre Brimont & Sylvain Kubicki CRP Henri Tudor CRP Henri Tudor, three objectives Research: Contribute through scientific excellence to the production and transfer of knowledge and to the international recognition of the scientific community in Luxembourg. Innovation: Sustainably strengthen the innovation capacity of companies and public organisations. Policy support: Support through research and innovation, the definition, implementation and evaluation of national public policies. CRP Henri Tudor Scientific & Technological Domains: Materials technologies Environmental technologies Health care technologies Information and communication technologies Business organisation and management Key Economic Sectors: • Industrial Production and Manufacturing • Construction and Building • Transport and Logistics • Service Industry • IT, Multimedia and Communication • Finance and Banking • Healthcare, Medical and Social • Governmental and Public Organisations Construction @ CRP Henri Tudor Construction Program. Our competencies • Business “experts” (Architects, Civil Engineer / Dr., PhD students) • IT scientists • Appropriation, networking, IPR Our team is historically involved in CRTI-B innovation projects (http://www.crti-b.lu) Today Tudor is co-animator of the NeoBuild innovation pole (http://www.neobuild.lu) Context 2020 challenge in the construction industry • Towards zero-energy buildings (EU regulations for new buildings) Passiv/Positiv energy buildings characteristics • • Very high level of insulation and airtightness of interior spaces Heating, Ventilation and Air Conditioning become high-tech systems Context Most of new-built houses are passiv houses, with high control of: • Heat recovery ventilation, insulation, solar gains Issues are emerging from these technologydriven design choices (Hasselaar 2008) • Comfort (overheating), noise (from installations/systems), health risks (legionella contamination of domestic water buffers, moistures because of low ventilation volumes) Context Building pathology data • • Usually comes from the assessment of insurance agencies experience Could be widely collected from sensors implemented within buildings, buildings elements and equipments Air-moisture sensor (Savory et al. 2012) An example: • Multi-layer wall panels in wood construction Source: Leverwood Big Data relevance Sensor mesures Context metadata Linear and trustfull sources No real time Security perspective Modeling : use of the BIM Challenges and Opportunities with Big Data Computing Community Consortium www.cra.org/ccc Source: Autodesk BIM According to most of the practitioners and researchers, BIM is both • • Product modeling, i.e. modeling of building-related information, Process modeling, i.e. the way practitioners contribute to a single/interoperable model of the (future) building Towards standardization (BuildingSMART, research community) • • • IFC: standardizing product model (expected software interoperability) IDM: standardizing process model (understanding collaborative work process) IFD: effort towards common definitions and translations BIM BIM through the life-cycle of a building/facility Source: www.bccomfort.com BIM as a step to big data modeling buildingSMART data model standard • IFC (ISO 16739:2013) • Usually implemented by AEC software vendors IFC Property Sets • Define all dynamically extensible properties. • Can be customely defined (e.g. for sensorsspecific data modeling?) www.buildingsmart-tech.org Thank you for your attention pierre.brimont@tudor.lu sylvain.kubicki@tudor.lu
