Part of one of the most significant capital projects in Washington University in St. Louis’ recent history, McKelvey Hall is the new home of the Department of Computer Science and Engineering. Perkins Eastman’s design honors the vision of long-time dean, James McKelvey, and provides a state-of-the-art environment for high-impact research and training for future computation researchers, computer scientists and engineers. The new building’s primary exterior corresponds with the surrounding traditional campus architecture, while the courtyard-facing exterior provides a dramatic window into the contemporary computational research spaces. With flexible interior layouts, the building fosters collaboration and a range of research and engagement activities. With attention to solar orientation, energy efficiency, low impact materials, reuse, recycling, and health and wellness, McKelvey Hall’s design relies on multiple sustainability efforts to meet the University’s operational goals.
