The building at 2100 Franklin Street will be the first new Class A Downtown office building to be built in Oakland since the year 2002. The new building will have a total area of 183,700 square feet. It is located adjacent to the 2101 Webster building and when complete, the two office buildings will be physically and functionally integrated to form "Center 21," one of Oakland's largest commercial office complexes. 2100 Franklin is registered as a LEED for Core and Shell pilot project and is being designed with the goal of achieving a LEED Silver rating. Its energy-conscious features include a high-performance building skin, variable speed fan drives/pumps, abundant natural light, and efficient mechanical, electrical, and plumbing systems.
