100 Park Avenue

Location:New York, NY
Architect:Moed de Armas & Shannon Architects
Client:SL Green Realty Corporation / Prudential Real Estate Development

Located near Grand Central Terminal, 100 Park Avenue was originally constructed in 1950 as Park Avenue’s first modern glass and steel tower, and at the time ushered in a new era of skyscrapers. The renovation from 2006 until 2008 includes a new two-story atrium lobby, stunning new glass façade, sleek new elevator cabs with glass and stone accents, new HVAC systems, upgraded electric capacity, a new emergency generator, green roofs, and state-of-the-art security. The project won two international BOMA awards for “Best Renovated Building of the Year” in 2008 and 2009.

Vidaris was responsible for the consulting and monitoring of the exterior recladding, replacement of 2,500 insulated high-performance windows, and roofing. The exterior recladding was essential to improve the overall efficiency of the building envelope. The existing retail storefronts were removed and replaced with new tempered glass storefronts with steel-reinforced aluminum mullions and stainless steel base and trim. The north and south facades were overclad with closed system kynarbased coated aluminum composite metal panels, responding to the metal and masonry facades of the surrounding buildings. To achieve the LEED® Silver rating, the original windows were replaced with new insulated glass and kynar-based coated aluminum windows and the adjacent mullions refinished with a low VOC resinous coating. The recycling capabilities and energy management program was enhanced to include the installation of low-flow plumbing fixtures that reduce water consumption by an estimated 50% or almost one million gallons of water per year. The installation of green roofs, a total of 14 in all, employ a low-maintenance/water consumption Xeroflor mat system.
