110 Central Park South was built in the late 1920’s, originally consisting of 24 floors, to which three more floors were added during a recent renovation. The original exterior walls are comprised of brick, masonry laid in Flemish bond, ornamental terra cotta cornices, architectural cast stone balustrades and parapets, and cast iron window bays with replacement aluminum windows.

The current building owners and property management engaged Vidaris to work on the facade and during this assessment, defficiencies within the PTAC Unit assemblies became obvious. Vidaris Building & Energy Sciences joined the project to analyze, and recommend solutions for excess humidity and condensation issues prevalent throughout the building. Vidaris’ observation included non-destructive visual observation of exterior walls, windows and roof as well as thermal imaging of the façade interior and exterior elevations. In addition, a detailed observation of each apartment units HVAC systems was performed. As a result of the analysis, Vidaris identified deficiencies in the building envelope components including testing of indoor environmental conditions such as airflow, temperature and humidity, as well as improperly sealed HVAC sleeves, restriction of HVAC discharge airflow, deficient air outlet installation, and oversized equipment. This was the cause for excessive humidity conditions in the summer months as well as draft conditions in the winter months. Vidaris recommended remedial measures for each deficiency identified and is currently assisting the client in preparation for, and oversight of mock-up and associated construction activities required to correct each issue in 2011.
