Healthy buildings are often associated with openness, while secure facilities are seen as constrained and compartmentalized. This session bridges that gap through the Institute for Defense Analyses National Headquarters in Potomac Yard, Virginia, a two-tower workplace that achieved WELL Gold (2023) within a high-security environment integrated into a mixed-use community. The presenters will share design and material strategies that support occupant well-being, bring daylight into secure interiors, encourage movement through intentional circulation and stair placement, and provide secure outdoor amenities such as courtyards and terraces. The session also highlights low embodied carbon approaches, including concrete incorporating sequestered CO₂ and precast systems designed to reduce emissions while maintaining a contextual limestone aesthetic. Attendees will leave with practical methods to apply WELL principles to complex, security-driven projects while maintaining operational flexibility and community impact.
