La pensée créative est à l’innovation ce que les méthodes sont à la recherche scientifique: une base essentielle. Longtemps associés à une certaine part de mystère, les mécanismes intrinsèques de la créativité sont aujourd’hui peu à peu décryptés par les communautés de chercheurs actifs en ingénierie de la conception, en sciences sociales ou en psychologie. Un consensus semble se dégager quant à l’étendue de son application: la véritable valeur ajoutée de la créativité apparaît lorsqu’elle est appliquée, telle une culture d’entreprise, à toutes les strates d’un projet et lorsqu’elle est mise en oeuvre, sans distinction, par tout un chacun. Forts de ce constat, des entrepreneurs et inventeurs tels que David Kelley (fondateur d’IDEO, directeur de la d.school, Université de Stanford) ou Tim Brown (CEO actuel d’IDEO) ont activement développé une approche appelée le "Design Thinking". Celle-ci vise à démystifier et «décomplex(ifi)er» certains procédés favorisant la créativité et ainsi parvenir à décomplexer les acteurs généralement considérés comme «non créatifs». L’intervention abordera, au travers d’une vingtaine de «success stories», les concepts de base de la démarche. Elle se voudra avant tout à la portée de ceux et celles qui désirent ré-intégrer la créativité au sein de leur pratique professionnelle et, en finalité, augmenter leur potentiel innovant. [less ▲]

La posture créative est à l’innovation ce que l’excellence opérationnelle est à l’entreprise: une démarche désormais incontournable. Et pourtant les plus sceptiques poussent nos communautés, avec raison, à poursuivre la réflexion: que reste-t-il à apprendre des méthodes créatives divergentes, comme le brainstorming par exemple ? Comment éviter à l’avenir la mise en œuvre répétitive et décontextualisée de recettes « toutes faites » qui dénaturent la créativité et nuisent à sa crédibilité ? Ces inquiétudes seront analysées par Catherine Elsen à la lumière du Design Thinking, cette approche méthodologique qui pourrait bien faire favorablement évoluer les représentations et accompagner chaque entreprise dans la mise en œuvre d’un modèle créatif qui lui correspond réellement. Esquissée dès la fin des années 80 aux Etats-Unis par des entrepreneurs et innovateurs tels que David Kelley (fondateur d’IDEO, directeur de la d.school, Université de Stanford) ou Tim Brown (CEO actuel d’IDEO), la méthode repose sur deux piliers fondamentaux: l’approche empathique (du marché, des utilisateurs, mais aussi de l’entreprise elle-même) et le « quick and rough prototyping » (ou « protocept »), soit une matérialisation itérative précoce des idées, que certains qualifient d’agile. L’intervention abordera ces fondamentaux théoriques et leur mise en œuvre pratique au travers d’exemples d’applications et d’outils ré-appropriables. [less ▲]

The search for sustainability achievement in the building sector led to the use of crop-based insulation materials. Among these, raw products like plant straws bales can present elementary representative volumes (REVs) in the size order of several square centimeters. Fibers orientation may play an important role on material thermal behavior. Measuring their thermal conductivities with standard steady-state equipment can thus lead to some inaccuracies due to the necessity of resetting lower thickness samples. This paper presents a Guarded Hot Plate (GHP) apparatus designed to test high thickness samples, up to 40cm, with an accuracy of 2%. The different parts of the machine are described in details along with design process and challenges encountered. Temperature and heat flux measurements in the device represent critical design stages where optimal accuracy is needed in order to optimize the resulting global error. Regarding this, necessary numerical and experimental analyzes were conducted emphasizing on intrinsic systematic error assessment. To complete the study, some validations tests are performed on a reference material and other widely-spread polystyrene slabs. These tests take into account the optimal computation parameters resulting from the numerical analysis and the apparatus proved to be in accordance with accuracy requirements. [less ▲]

In this paper, we present an elegant solution for creating robust monolithic achromatic half-wave plates (HWPs) for the infrared, based on the form birefringence of subwavelength gratings (SWGs) made out of diamond. We use the rigorous coupled wave analysis to design the gratings. Our analysis shows that diamond, besides its outstanding physical and mechanical properties, is a suitable substrate to manufacture mid-infrared HWPs, thanks to its high refractive index which allows etching SWGs with lower aspect ratio. Based on our optized design, we manufactured a diamond HWP for the 11-13.2 µm region, with an estimated mean retardance ~3.143 ± 0.061 rad (180.08 ± 3.51°). In addition, an antireflective grating was etched on the backside of the wave plate, allowing a total tansmittance between 89 and 95% over the band. [less ▲]

This paper presents an innovative system comprising a heat pump connected to a solar roof and a geothermal heat exchanger. This heat pump is also able to invert its cycle and operate as an ORC. By using the whole rooftop (hereunder called “absorber”) as a heat source, a large amount of heat is generated throughout the year. This heat is used in priority to cover the building annual heating needs and the surplus heat generated during the summer is utilized to generate electricity in a so-called HP/ORC module. This paper will thus focus on these two main points: designing of the prototype and results from experimentation. This paper demonstrates the feasibility of such a prototype with encouraging performance in ORC and HP modes. Experimentally, a COP of 4.2 is reached in heat pump mode and a global efficiency of 5.6 is obtained in ORC mode. Possible means of improvement and perspectives are finally described. [less ▲]

Building is one of the economical sectors where solutions are available to significantly reduce energy consumption and greenhouse gases emissions. Among other, heat pumps offer promising perspectives to provide energy-efficient space and sanitary hot water heating in many applications. This paper presents an innovative system comprising a heat pump connected to a solar roof and a geothermal heat exchanger. This heat pump is also able to invert its cycle and operate as an ORC. By using the whole rooftop (hereunder called “absorber”) as a heat source, a large amount of heat is generated throughout the year. This heat is used in priority to cover the building annual heating needs and the surplus heat generated during the summer is utilized to generate electricity in the so-called HP/ORC module. The same module can be used during winter as an efficient heat pump which radically reduces the complexity of the total system. The main advantage of the proposed technology is due to the reversibility of scroll machines, which have proven to operate efficiently both as compressor and as an expander in lab testing. [less ▲]
