Classic New York Skyscraper Clad in Alcoa Architectural Building Material

August 10, 2010

NEW YORK--Alcoa’s Reynobond® aluminum composite material was selected for the façade of 100 Park Avenue, the first retrofit building in New York City to receive LEED (Leadership in Energy and Environmental Design) Silver certification.

100 Park Avenue was one of the first steel and glass modern skyscrapers that transformed Park Avenue into a desirable business address. The SL Green Realty Corporation and Prudential Real Estate commissioned Moed de Armas & Shannon Architect of New York, to transform the classic address into a “New Modern Classic,” a state-of-the-art corporate headquarters location constructed to sustainable design standards.

Metal was specified by the architects to give the tower a new modern perspective. Alcoa Architectural Products’ Reynobold® ACM with a Pewter, Kynar® finish was the material of choice for the exterior façade.

“One of the engineering challenges on this project was to develop a way to anchor the panel system over a deteriorating veneer brick façade without imparting any loads on the veneer brick,” said Michael Potkay, director of engineering for IDA International, Inc., a metals fabricator. “The light weight of the ACM panel was integral to achieving the resulting suspended system. The ACM panels provided the desired aesthetic, and their light weight made it possible to re-clad the building without adding stress to the original façade underneath. The high recycled content of the material also helped with the quest for LEED certification since ACM meets sustainable design standards. The architect selected Reynobond ACM, in particular for the façade, because of his long-standing relationship with IDA and experience working with Reynobond materials.”

When the $72 million redevelopment of the 36-story, 955,000-square-foot office tower was completed, the architects had doubled the height of the lobby and integrated new double-height retail storefronts into the lobby and building exterior. The infrastructure was upgraded: dated systems were replaced with state-of-the-art electric and HVAC systems.

Additional sustainable amenities include 14 green roofs, which employ a low-maintenance/water consumption Xero Flor® mat system; enhanced recycling capabilities; and an energy management program that includes the installation of low-flow plumbing fixtures that reduce water consumption by approximately 50 percent a year.
