Low VOC materials were chosen throughout the building to help gain LEED credits. Interior finishes include ceramic flooring, terrazzo flooring, low VOC carpet, acoustical ceiling tiles and wall treatments, and variety of paint colors. The building includes all major electrical, mechanical, plumbing and fire protection systems. The roof is a flat all-white roof, which helped to earn an additional LEED® credit for reducing the heat island effect. The structure is a cast-in-place concrete frame covered with brick, glass and metal panels. This allows greater access by the scientists to equipment that may not be needed on a daily basis.Īnti-terrorism/force protection measures include building access control, site perimeter control, building standoff distance from the street and surface parking, fire protection mass notification system, outward opening entrance doors, controlled roof access, air intake system located in penthouse, redundant M/E/P systems, no under building access, and public drive-up and drop-off areas are set away from the front entrance. In an effort to help maximize laboratory space, each hallway in the laboratory wing has a community room equipped with fume hood, eye washing station, and deep sink. Certain laboratories also contained acid waste piping and an acid waste treatment system to filter the acids released during laboratory work. Other unique equipment needed for the BSL-2 laboratories are a limited access system, impermeable work surfaces, hand and eye washing stations, load bearing furniture, differential air pressure, and fire and respiratory protection. The air filtration is a foundation to the BSL-2 laboratories because it allows them to maintain a clean room classification of 10,000. The laboratories also require a constant air flow with HEPA purification on the supply air to reduce the possibly of contaminating a work sample. For example, each laboratory is equipped with a fume hoods for working with aerosols or substances that may splash. The four BSL-2 laboratories require significant M/E/P resources to maintain the sterile research environment. Silane gas has a dedicated vent line to the building roof where, as it reaches oxygen, it will instantly combust into a constant blue flame. Another laboratory has a dedicated supply of silane gas (SiH4). Boron is widely used for its ability to absorb neutrons without forming unstable atoms. One of the laboratories was coated with the chemical element Boron. Several of the laboratories required unique materials or construction. Each of these laboratories requires an uninterrupted flow of fresh air, full coverage by the fire protection system, electricity with full emergency back-up, and limited access security measures. The project includes electronic (including low frequency, electromagnetic, photonics, and an experimental test range), chemical, optical and infrared, and computer laboratories. The fire alarm system is a VESDA (very early smoke detection apparatus). Information technology needs included data closets with UPS power back-up, cable trays for security, communication, and IT cabling. The electrical needs of the building are unique because they include a dual feeder incoming service as well as UPS back-up power all integrated with an advanced grounding and lightning protection system. The massive system was designed to feed each laboratory, individually, as well as service 110,000 square feet of the administrative wing. The 90 laboratories required extensive M/E/P systems because of the advanced research that will be completed in this wing. Although smaller in size, the design of the laboratory wing drove the mechanical, electrical and plumbing (M/E/P) needs for the ESB. The other third of the Exploration Sciences Building is the laboratory wing. The administrative wing also houses a 200-seat symposium room, several conference rooms of various sizes, three open collaboration areas, and a cafe with commercial kitchen. 500 offices make up the majority of the administrative wing. Two-thirds of the Exploration Sciences Building is a three-story office building. This project is Leadership in Energy and Environmental Design (LEED) Gold certified by the U.S. The structure is cast-in-place concrete frame covered with brick, glass and metal panels. The Exploration Sciences Building (ESB) project at the NASA Goddard Space Flight Center is a 200,000-square-foot, three-story office and laboratory building with electronic, chemistry and computer labs.
