This Teaching Unit is an introduction to a series of knowlege and issues at stake, necessary and critical, in an evolving practice of the architectural projetc at a global scale. Understanding and mastering these knowledge and technologies within a semester, thanks to a series of exercices applied to a case study of small scale, would allow for practical reuse and implementation in future projects. The case study is a bus stop shelter project conceived and realized by Richter Dahl Rocha & Associés at Ecublens, Abribus RC1 and with whom we will be in direct exchange during the semester. The content of the unit is organised along the three first phases of an architectural project. Each session consists in an introductory lecture of 30 minutes and followed by applied exercices on the same topic. Each phase will enriched by one or two lectures from an external personality.
