The new tenants are the Office of the Comptroller of the Currency, the Federal Housing Finance Agency, and the Securities and Exchange Commission, all of which will enjoy the benefit of the building's cutting-edge technology, security standards that exceed ISC Level IV, and an anticipated LEED™ Gold rating.
