The building, designed by Rafael Viñoly, wide at the ground floor, is built into a hill and designed to be the primary research facility. A 96 room hotel for conference attendees overlooks a pond and connects to the Landscape Building via a tunnel under Helix drive. Selden Island, a former sod farm in the Potomac River was added to the campus in 2004 and is popular amongst staff for jogging and recreation. Many employees live on campus. There are two apartments buildings totaling 140 units, 34 single-family townhouses and 21 studio apartments providing housing for more than a quarter of the staff, with another 100 unit apartment under construction as of 2022. Other employees commute to Arlington on an HHMI provided shuttle bus. There are extensive fitness facilities, including a yoga studio, bouldering gym, tennis courts and a soccer field. Site and landscape design were completed by Dewberry in 2006 and include over four acres of green roof meadow plantings which blend the building into the surrounding site. In 2006, the institute hired landscape architecture firm Lewis Scully Gionet, Inc., to redo some of the previous landscape work which was completed in fall 2008 (and won an Honor Award from the Maryland and Potomac chapters of the American Society of Landscape Architects). This work includes an architectural water feature, expanded path network, and siting of multiple pieces of artwork, as well as comprehensive planting additions. Additional campus-wide landscape improvement designed by LSG Landscape Architecture followed up until now. Research Facilities Computational Infrastructure The storage and computational requirements of modern neuroscience can be extremely demanding. Some two-photon microscopes can generate data at over 5GB/s. Electron microscopy connectomics can be especially demanding. The FlyEM dataset alone is a 400TB, 34431 x 39743 x 41407 64-bit image. The analysis of a similar dataset took nearly 7000 GPU hours. Computational infrastructure available to researchers at Janelia includes a high performance 7000 core cluster, 5 petabytes of storage and an off-site data center where data is backed up nightly. Animal Facilities An accredited vivarium houses laboratory animals including zebrafish, mice and rats. Support staff assist with routine care, breeding and surgeries. Routine care is aided by automation. Several fly flipping robots help maintain Drosophila stocks by transferring them to vials of fresh food. Two robot arms aid in the sanitation of mouse cages. One arm picks dirty cages from a stack and inserts them into
