President of Alcoa Building and Construction Outlines Key Green
Building Solutions and Initiatives

NEW YORK–Alcoa (NYSE:AA) today participated in the White House Better Buildings
Roundtable, contributing to the national dialogue on how public-private
partnerships can advance the green building sector, drive innovation and
stimulate economic growth.

Glen Morrison, President, Alcoa Building and Construction Systems, took
part in the Roundtable as part of the Company’s commitment to the Better
Buildings, Better Plants Challenge, a U.S. Department of Energy
initiative aimed at making commercial buildings 20 percent more energy
efficient by 2020 and accelerating private sector investment in energy
efficiency.

“Last year, the buildings in which we work and live used roughly 40
percent of the energy in the U.S. economy at a cost of over $400
billion,” said Mr. Morrison.

“Through a variety of efficiency improvements we can make these
buildings more energy efficient, while creating jobs and building a
stronger economy.”

Non-residential green building activity is expected to triple between
2010 and 2015, according to McGraw-Hill Construction’s Green
Outlook 2011: Green Trends Driving Growth. Alcoa Building and
Construction Systems is capturing this opportunity by bringing
innovative solutions to market, and in the last year has had a record
number of patents either issued or in process.

Recently announced Alcoa innovations include OptiQ™ Ultra Thermal
Windows, developed with the support of a grant from the U.S. Department
of Energy; the Kawneer product suite of high-performing curtain wall
systems, energy-saving sunshades and hurricane-resistant framing
solutions; and Reynobond® with EcoClean™, the first coil-coated
architectural building panel that cleans itself and the air around it.

Alcoa has joined President Obama’s Better Buildings, Better Plants
Challenge to improve energy efficiency in commercial and industrial
buildings across the country. The Company is implementing an
enterprise-wide energy reduction initiative to decrease energy use in
its Global Primary Products division by 10 percent and its other
businesses by 20 percent by 2020.
