Abstract: Built to Specifications (Built2Spec) is a Horizon 2020 EU-funded project involving 20 European partners that seeks to reduce the gap between a building’s designed and as-built energy performance. To do this, the project will put a new set of breakthrough technological advances for self-inspection checks and quality assurance measures into the hands of construction professionals. This collection of smart tools will help building stakeholders at all levels in meeting EU energy efficiency targets, new build standards and related policy goals.
Built2Spec will deliver a new set of tools:
All connected to a Virtual Construction Management Platform supporting the collection and sharing of all project data, from initial design to the delivery. During the project, this platform will be integrated into the operations of small and medium-sized enterprise (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.
Collaborations in European Programs, except FP7 & H2020
Collaboration with BAM, Berlin
Participants : Laurent Mevel, Michael Doehler, Eva Viefhues.
Eva Viefhues is currently student in BAM, Berlin. a PhD will start in 2016. Michael Doehler has visited a few times BAM in 2015 to prepare and plan the PhD.
Collaboration with CNR-IREA, Italy
Participants : Jean Dumoulin, Nicolas Le Touz.
This internship aims to identify defects in the interior walls, using thermal and electromagnetic reconstruction method, developed by IFSTTAR (in Bouguenais) for thermal and CNR-IREA (in Naples) for electromagnetism.
First, we make a numerical study for the two direct problems, with the resolution of the heat equation with finite elements, allowing a detailed study of how is made the assembly of matrices for a problem in two or three dimensions. A study of Maxwell’s equations solving by using a centered finite difference method is also conducted for the direct problem of electromagnetism.
We also study the resolution of these inverse problems, in particular with the calculation of a functional gradient using the adjoint method for the thermal reconstruction, what allows the resolution of the problem with the Levenberg-Marquardt algorithm, and a study of the Born model for the electromagnetism problem.
Applications to the reconstructions of various types of defects are then lead. These different situations allow to highlight the stimuli, thermal of electrical, to bring to the system so that the reconstruction is made correctly. We could thus reconstruct defects in domains of various dimensions with thermal or electromagnetism highlighting the electrical (conductivity, permittivity and permeability), thermal (effusivity) and mathematical parameters (regularization terms) playing on the fidelity of the reconstruction.
A coupling of these two reconstruction methods is then carried out to improve the fidelity of the reconstructions realized with only one of these two methods. In the case of this coupling, the reconstruction get with GPR data provides a priori information to the thermal inverse problem allowing to get a better location of the defects.
European Research Network on System Identification (ERNSI)
Participants : Qinghua Zhang, Michael Doehler, Laurent Mevel.
The I4S project-team is involved in the activities of the European Research Network on System Identification (ERNSI) federating major European research teams on system identification. Modeling of dynamical systems is fundamental in almost all disciplines of science and engineering, ranging from life science to process control. System identification concerns the construction, estimation and validation of mathematical models of dynamical physical or engineering phenomena from experimental data.
MODRIO
Participants : Qinghua Zhang, Liangquan Zhang.

Objectif: To meet the evermore stringent safety and environmental regulations for power plants and transportation vehicles, system operators need new techniques to improve system diagnosis and operation.

Abstract: Open standards are necessary for different teams to cooperate by sharing compatible information and data. To meet the evermore stringent safety and environmental regulations for power plants and transportation vehicles, system operators need new techniques to improve system diagnosis and operation. Open standards are necessary for different teams to cooperate by sharing compatible information and data. The objective of the MODRIO project is to extend modeling and simulation tools based on open standards from system design to system diagnosis and operation. This project joined by partners from Austria, Belgium, Finland, France, Germany, Italy and Sweden has been selected by the board of Information Technology for European Advancement (ITEA 2). The involved Inria project-teams are PARKAS, HYCOMES and I4S. This project is funded from June 2012 to November 2015.
COST Action TU 1402

Objectif: Quantifying the value of structural health monitoring
-
Partner: 23 countries, see http://www.cost.eu/COST_Actions/tud/Actions/TU1402
-
Abstract: This COST Action enhances the benefit of Structural Health Monitoring (SHM) by novel utilization of applied decision analysis on how to assess the value of SHM - even before it is implemented. This improves decision basis for design, operation and life-cycle integrity management of structures and facilitates more cost efficient, reliable and safe strategies for maintaining and developing the built environment to the benefit of society. SHM is increasingly applied for collecting information on loads and aggressive environments acting on structures, structural performances, deterioration processes and changes in the use of structures. However, there is an urgent need to establish a better understanding of the value of SHM before its implementation, together with practically applicable methods and tools for its quantification. This Action thus aims to develop and describe a theoretical framework, together with methods, tools, guidelines, examples and educational activities, for the quantification of the value of SHM. The COST Action will be conducted with the support of the Joint Committee on Structural Safety (JCSS). The networks of researchers and industries established during COST Actions TU0601, C26, E55 and E24, the EU FP7 project IRIS, the Marie Curie Network SmartEn and the JCSS will ensure visibility, impact and dissemination.
