SITE ANALYSIS &
DEVELOPMENT
A paved plaza would be transformed into a
functional oasis where storm water is captured
by permeable pavers and gray and black water
is filtered through a microalgae pond.
Process Zero.
Research led Quinn to an emerging
technology. Scientists have tested
large-scale cultivation of microalgae
in horizontal and vertical glass tubes,
rather than in open-air ponds. Quinn
transferred the mechanics of tube
technology to the side of a building,
adding a full-scale closed system of
continued from page 104
holding tanks and filtration ponds to
complete the bioenergy network. Inside
the glass tubes, the plants swim in
a slurry of recycled wastewater and
consume carbon dioxide siphoned
from an air-intake pipe at the freeway.
In principle, photosynthesis would
be assured, oxygen pumped out to
the street as continued on page 131
Process Zero argues for fundamentally
reengineering the building.
ATRIUM & LIGHT-WELL
DEVELOPMENT
Bringing daylight to 100 percent of office
space and shifting workers to cloud computing enable the Process Zero retrofit team
to project energy savings of 80 percent.
