The National Park Service (NPS) required an assessment of the Clara Barton House. The house served as a museum displaying Clara Barton’s foundation of the Red Cross. The building had many deficiencies from neglect over the years. There was extensive water penetration along the envelope. Several of the original window panes were cracked. The foundation was inadequate for keeping water out. The mechanical system needed an upgrade, however, the exterior of the building leaked drastically. The proposed solution was to fix the water and air infiltrations, fix the roof expansion joint and provide a 50-ton air cooler to maintain the appropriate set-points.
