With its silvery metal panels and glass cladding, and a canted photovoltaic (PV) array that projects beyond the edges of the roof like the brim of a hat, the recently completed six-story Bullitt Center in Seattle’s Capitol Hill neighborhood doesn’t at all resemble a Douglas-fir forest, admits Denis Hayes. Nevertheless, Hayes, who is president and CEO of the Bullitt Foundation, is fond of comparing the 52,000-square-foot office building to just such a forest. “It functions like one,” he maintains.
Appearances aside, Hayes’s metaphor is apt. If the $18.5 million building operates as intended, it will be self-sufficient in much the same way a forest is: It will obtain all its water from the rain that falls on the site, and over the course of a year, will consume no more electricity than is generated by the roof’s PVs.
