For use by communication managers at Tractebel Engineering and its subsidiaries, the "Moodbook" lays down the new visual identity devised by Concerto since 2006. Baseline, logo, typeface, iconographic and editorial approach, templates... Every element associated with the image of the group is set out in clear and pragmatic detail, explaining the "why" as well as the "how". A highly strategic tool in formulating consistent communication and building a strong image.
