Office Building 4220

Building 4220 is the first major replacement building in the main administrative 4200 complex at the Marshall Space Flight Center.  The project replaces an existing facility with a new five-story, 150,000-square-foot administrative building. Designed to be energy and operationally efficient, the new facility includes a large atrium gathering space, open office areas, a variety of conference rooms, collaboration space, balconies and information technology support spaces.  4220 is LEED Silver Certified.

Key aspects of the design include:

  • Massing and use of glass and metal elements that are aesthetically compatible with existing 4200 complex and the historic Marshall Space Flight Center.
  • Building and site designed as part of an integrated campus master plan, incorporating a future quadrangle and greenway to enhance the pedestrian-friendly nature of the complex.
  • NASA Building 4220 has been awarded LEED Silver certification from the USGBC. Some sustainable features include solar photovoltaic panels, HVAC energy recovery units, a rainwater collection cistern supplying irrigation water, permeable hardscape plaza pavers, and native landscaping.
