Lightweight construction correspond to wooden-framed or prefabricated system fulfilled with a lightweight biobased material. Knowing the technical aspects, limitations and solutions, rules, public market, but also building physic is essential for a good conception and the management of the project.

Regenerative materials come in a wide variety of forms and compositions, from raw materials to industrialized construction systems. Knowing the specificities of these different materials is needed to adopt the appropriate constructive choice adapted to the socio-economic situation of the territory and the resource availability.

Earth construction is attracting attention in contemporary construction. New strategies have been developed for innovation, combining traditional techniques with modern construction systems and new materials. These constructions are still challenging with regards to standards and building codes, but many solutions exist to fulfil the expectation and ambition to make a different architecture.

Building materials with a special focus on regenerative materials: earth, bio-based and reuse.Looking at material sourcing, properties and performance, as well as how they are integrated in the buildings (building envelope and detailing).

The last module of the CAS consists in an individual or group project exercise, that will be presented during a final review on the 15th of May 2020

New construction represent only one percent of construction per year in European countries. Re-valuing the existing building stock is therefore a priority. Using bio-based insulation for energy retrofit and the reuse of building component in case of building demolition represent promising carbon-neutral solutions for the construction sector.
