Pioneering LEED v4The Bown Library! Case Study
Copyright© 2017 by RWDI. All rights reserved.
The project team chose to implement LEED v4 before the registration deadline was established, resulting in a truly pioneering effort to certify before most projects considered taking the plunge. This choice was a collaborative decision between the design team, construction team, and key stakeholders.
