Architizer is "the largest platform for architecture and design online hosting projects uploaded by the designers themselves." At time of this writing, it is hosting 54,434 projects, so it's no surprise that its awards program should be huge too. Winners are selected by jury and by popular choice. Here's a quick snapshot of the Architecture +Sustainability finalists and winner, starting with the Bullitt Center. This really is a no-brainer this year, it's accurately self-described as the greenest building in America, possibly the world.
The Bullitt Center collects rainwater for potable and non-potable use, and all materials and systems were vetted against a 'red list' of prohibited toxins. Building occupants utilize the only known six story compositng toilet system in the world, a true feat of engineering and design.
