Pursuing LEED Platinum®

Capitol Tower (now Bank of America Tower)


Walter P Moore is providing structural, civil, traffic engineering, and parking consulting services for this new high-rise office building in downtown Houston. The project includes 25 floors of office space above a 10-story podium parking garage.

The front of the building faces Capitol rather than Rusk, an improvement that will ease traffic flow for those entering downtown from the north, and features a glass façade accented by LED-lined light boxes. The underground tunnel bound by Capitol, Milam, Rusk, and Travis includes a two-level plaza filled with restaurants, retail, and amenities with an inviting common area. The plaza opens to the north, where the orientation allows for maximum daylight.

Capitol Tower was one of 100 projects selected for the pilot program of LEED Version 4, and is one of three projects in the world to achieve LEED v4 Core and Shell Platinum Pre-Certification. To pursue Platinum certification, the project needed to achieve the majority of the revamped Materials and Resources credits. This included the Whole Building Life Cycle Assessment credit, which Walter P Moore led. Capitol Tower is the only project in the LEED v4 Beta program to attempt this credit.

To achieve the credit, which recognizes a building’s reduction in the impacts associated with the manufacturing and installing of materials, Walter P Moore used the ATHENA Impact Estimator to help quantify the significant sources of environmental impacts. Based on the studies, the team developed a strategy of aggressive cement minimization, which led to a projected 19% reduction in Global Warming Potential and a 12% reduction in acidification.
