Health-care facility managers are confronted by an increasing inventory of aging building stock and face the difficult decision on whether to remove these buildings and build new, re-purpose, or relocate operations. Hospital administrators particularly are reluctant to remove their aging existing structures due to the often limited availability of open areas to erect new buildings and because in many instances the existing facility must remain fully, or partially, operational. This presentation documents the complete renovation of a 70's era critical care building at Johns Hopkins Hospital while maintaining hospital operations throughout the construction phase. The highlight is an innovative approach that developed a high-performance, hybrid envelope system that results in a modern hospital design aesthetic that is highly energy efficient, environmentally sustainable, and improves building resiliency for decades to come.


1. Be able to better assess the code implications related to designing a new exterior enclosure on existing infrastructure to inform design decisions.
2. Appreciate the role that analysis and CAD technology plays in assessing, coordinating, and implementing design strategies for new enclosure design.
3. Examine the impact of design decisions on constructability related to cladding materials, fenestration, roofing and insulation of a new enclosure.
4. Understand strategies to future proof buildings through innovative design systems that address enclosure performance and sustainability objectives.
