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

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.
