The distance materials were transported (below) was a factor in determining their greenness.

B. Salvaged doors and windows for second-floor focus rooms from Berkeley, CA.

C. California black acadia for project rooms and salvaged metal for third-floor focus rooms from San Leandro, CA.

D. Reclaimed brick for first-floor conference rooms from San Francisco, CA.

E. Monterey cypress for meeting tables from street trees in Half Moon Bay, CA.

F. California sycamore for lunch tables from a yard tree in Geyersville, CA.

In fact, that's the story throughout: when you set uniquely high standards, you're bound to fall short. Consider something as humble as the cabinets in the kitchen pantries on each floor: the doors are made of pressed sunflower hulls; the knobs are smooth river stones. But the metal pieces connecting the two? They're as conventional as can be, with a manufacturing lineage that's hardly pure. In general, says Gensler project designer Diane Rehn, the goal of minimizing impacts on the environment as much as possible got tougher with each additional component in a particular area.

"There are varying shades of green; you can't go to a hardware store and specify recycled steel studs," Rehn says. "When you're selecting a wood, it's fairly easy. But when you get to things like desk chairs, with dozens of components from who knows where, it's more complex to get something really green." That's why Gensler decided to go with Aeron chairs; viewed through the sustainability prism, they were better relative to the competition, even if only so-so in an absolute sense. "Work chairs are a lot of plastic and a lot of steel," project director Dominic Sarica sighs.

Even the most striking instances of reuse can come with angles of doubt. You obsess about them, or declare partial victory and move on. For example, a small conference room on the second floor: the walls are made of framed windows chosen on-site at Urban Ore, a legendary salvage operation in Berkeley. "We wanted to get some humor in the building, break up the monotony," Bartolucci says. "Is the paint on the frames 'good' paint? Probably not. But we're reusing old windows!"

The conference room that's her favorite, though, is the main one on the second floor. The centerpiece is a vast table made of planks from a single bay laurel tree found lying on the ground at a yoga retreat in Marin County. The walls are made of wood from a Midwestern barn. The doors were milled from raw wood debris by Woodworks, an organization in Oakland that employs disadvantaged youth. The ceiling insulation? Natural fiber made from aspen wood. "This room kind of represents what we want to be," Bartolucci says. "It's honest and open."

The conference room also shows that even when sustainability is a priority, it's not the only goal. "Transparency is a key thing, and this is a technology-based company," Bartolucci says. So the conference room has glass walls as well as the barn wood, and the huge doors slide easily, often staying open. The videoconferencing system is elaborate beyond Max Headroom's dreams.

While Moore settles in, Gensler is applying the lessons it has learned. The firm's new San Francisco office, on the waterfront south of the Ferry Building, will be geared toward qualifying for LEED's new commercial interior certification, with an emphasis on reuse of materials. And the San Francisco team has passed along its experiences at the Presidio, both positive and negative, to Gensler's company-wide sustainable design committee.

For all the strain that comes from pushing limits, the Gensler designers see progress in the way the building industry is responding to the emerging market demand for all things green. "Even when suppliers couldn't come through for us," Burry says, "we heard a lot of positive feedback: 'We don't have product yet, but tell us what you find. And give us a year.' When a client like this takes a stand, it makes a few manufacturers wake up."
