The Gensler-designed Capitol Tower, a 34-story speculative office building developed by Skanska USA on the site of the former Houston Club in downtown Houston, Texas, has been awarded Platinum Pre-Certification under the U.S. Green Building Council’s LEED v4 ranking system. According to a press release put out by Skanska, the project is one of only a handful of in-the-works buildings to earn the distinction under the fourth generation of the LEED system. The company also stated that it wished Capitol Tower to be the greenest building in Houston. The design includes a high-performance facade system, daylight harvesting technology to reduce energy use, 90 percent access to daylight and views for tenants, a garage with daylight occupancy sensors and a green roof, alternative vehicle charging stations, a rainwater collection system, and bicycle amenities to encourage cycle commuting, among other sustainable features.

“Skanska made it clear from the beginning of the design process that they wanted this to be the most sustainable building in Houston,” Gensler principal Kristopher Stuart said in a statement. “We really pushed our team to move beyond anything we have done before to create a building that offers an exceptional work environment in a high-performance envelope that will dramatically reduce operating costs. The design also places an extraordinary emphasis on public spaces and pedestrian experiences which we believe will greatly enhance and enrich Houston’s urban fabric.”
Under the LEED system, pre-certification allows owners to begin to market the proposed green features of a project to prospective tenants who wish to occupy a LEED certified space. Earning a pre-certification is not a guarantee of actual LEED certification. While the pre-certification review is conducted in the same manner as a combined design and construction review, no credits or pre-requisites can be awarded. They are instead marked as “anticipated.” In addition, only projects registered under the LEED for Core & Shell rating system can apply for pre-certification.
