When I joined the National Team of the nonprofit Engineers for a Sustainable World (ESW) in the summer of 2013, the group had a logo and a shade of green, but little else in the way of a polished or consistent brand. From my very first contacts with the team at a retreat during that summer, I set about building a visual identity and branding guidelines and materials for the group, including logo variations, typographic families, a color palette, and supporting materials to help members of the national team implement designs.
I led a brainstorm with the entire National Team to nail down six key adjectives that capture how ESW perceives itself as an organization and wishes to be perceived by the public. Building off of those core values, I went through iterations with other members of the team and a graphic design professional to develop a color palette, choose open-source typographic families that fit the group's needs, and develop an iBook/PDF Branding Guide for general consumption by the national team and the organization's hundreds of student and professional members.
The latest iteration of my efforts is visible to the public at http://eswusa.org/drupal/brand.
