Innovative ultra-low Carbon building Steel Envelop systems with Bio-based insulation

ended

The strategic objective of the “Innovative Ultra-low Carbon Building Steel Envelop systems with Bio-based Insulation (InCSEB)” project is to develop five innovative ultra-low carbon building steel envelop systems thanks to the innovative use of wood fiber, a renewable and bio-sourced insulation material, while achieving a high level of thermal performance and ensuring compliance with other requirements such as mechanical, fire and acoustic. The projected Global Warming Potential (GWP) gain of these innovative systems is likely to exceed 60% compared to conventional systems for a comparable thermal performance. The five systems studied, which have all been selected because of their market reach in the European Union, include three sandwich panels systems (pitch and flat roofing and cladding), one double skin system and one facade cladding (cassette). A detailed experimental, analytical and interpretation programme based on relevant classification reports has been designed for each of these systems with a series of tests to evaluate their mechanical, thermal, fire, acoustic performances together with their air, water, and vapour permeability. Two full scale prototypes will be built incorporating the new systems to evaluate their behaviour and durability when exposed to the real-life. The indicators of life cycle assessment (LCA) for the systems studied will be calculated and the benefits in terms of carbon footprint (GWP) will be evaluated by comparing the current situation of a steel office building in France with that of the same building should it had been fitted originally with the five new steel envelops. Five generic BIM objects will be produced. Three draft amendments will be prepared and submitted to CEN. The industrial partners intend to submit four patents to the European Patent Office. The partners have also planned to carry out a strong activity of dissemination of the innovative solutions to stakeholders across the European Union (publications, workshop)
