Greenbuild is the largest international conference and expo devoted to sustainable building, development, and urban planning. The new technologies driving “smart buildings” are a key focus for Greenbuild 2012, which this series of print ads represent through “conversations” between buildings and their inhabitants. Illustrating the 2012 theme, @Greenbuild, the placemarkers in this campaign represent location, technology, and the interaction between people and their environments. Our text—Build Smarter, Build Dialog, and Build Momentum—pairs with a series of progressively wider photos of San Francisco.
