Our Partners

We wanted to do this right – to design a sustainability retrofit that would not only make our building more energy efficient, but one that could serve as a template for other buildings worldwide. We wanted to make the case that energy efficiency is not a sacrifice; it's smart business. We partnered with a number of global leaders, forming a team that is committed not just to this project, but to creating a more sustainable model for energy consumption around the world. We look forward to seeing that team's success continue to impact our global community.
