National Award-Winning, phased rehabilitation and adaptive reuse of National Register Listed, (c.1866) Old Naval Hospital. A deteriorating former federal government building was preserved and transformed into a vibrant cultural center for education and the arts for the Capitol Hill Neighborhood. All work was subject to Section 106 of the National Historic Preservation Act. The second and third phases of the project, for a non-profit organization holding a long-term lease of the property, were partially funded by the US Government, the DC Government, private donations, Historic Rehabilitation Tax Credits and a Save America’s Treasures Grant.
This three phase project was designed to target LEED silver standards and required the repair and support of historic masonry bearing walls and chimneys, structural wood framing and original wood flooring and ornamental wood and iron stairs. Interior rehabilitation included flat plaster repair, wood doors, windows, trim repair, replication and finishing, based on historic finish analysis. The main building received a new elevator, provided Universal Accessibility (ADA compliance) to all levels and fully rehabilitated interior upgrades. The site also made use of a geo-exchange system to avoid the use of above-ground heating and cooling units on the site. The buildings’ metal roofs, slate mansard, brick and stone walls, wood windows and doors and period lighting were rehabilitated with new air, vapor and thermal barriers. The building now houses classrooms, meeting spaces, offices and other multi-purpose spaces.
Challenges and Solutions
• Historic Rehabilitation Tax Credit and Save Americas Treasures Grant funding
• IBC Existing Building Code 2006- Performance-Based Code Compliance
• Restored open three-story ornamental wood stair
• New egress stairs inserted into historic spaces
• Geo-exchange system, extremely energy-efficient/quiet HVAC, avoided on-site combustion heating/cooling tower
• New energy efficient elevator for accessibility to all 4 floors with underpinned foundation walls
• Low-Impact Development (rain garden, pervious pavement)
• Provide building wheelchair access at lowest level to avoid unsightly ramps and lifts at exterior
• Selective removal of masonry walls to create large multi-use assembly spaces
