With an aim to grow the green economy and make Oregon a world-class leader in sustainability, Oregon Sustainability Center is on its way to construct the Living Building challenge. What will be known as the largest certified office tower in the world is expected to be net-zero energy and net-zero water use development. The Portland-based skyscraper will incorporate features like natural lighting, floor plan and building materials that maximize natural cooling and solar panels to provide energy and shade. The stunning trees and plants that will beautify the structure will be irrigated with the collected rainwater, while the grey water will be recycled for use. The building will contain offices for non-profits that collectively make up the Center as well as a campus facility for the Oregon University System.
