maintaining superior performance
for one year.
Mickey Leland
Federal Building
Houston, TX
In 2011, Gensler, Gilbane and the General Services Administration (GSA) collaborated to renovate
the Mickey Leland Federal Building, an occupied 23 story building in downtown Houston, Texas.
The project utilizes the design-build process to establish a new standard n sustainable renovation,
featuring: high-performance exterior cladding, an inviting lobby, and modernized mechanical and
lighting systems. Energy conservation and long-term energy cost savings are essential components
of the design team's commitment to environmental stewardship.
