T he West Branch Library in West Berkeley, Calif., had outgrown its space by the late 2000s. After a study found it was more beneficial to build from scratch rather than renovate, the old
library was demolished. In its place now stands a new zero net energy
(ZNE) library highlighted on Page 6.
While the City of Berkeley had previously passed a citywide climate
action plan, the library was not linked to those goals. However, the
architects saw an opportunity for synergy with those goals in recommending a ZNE facility. Their vision included generous daylight, natural ventilation and spacious reading rooms.
The new building allowed for better use of the tight site area and a
more open and flexible library layout to meet community needs.
Incentives from Pacific Gas & Electric were used to offset some
design fees and established the library as a pilot ZNE project for the
utility. This official project goal helped the client, key stakeholders,
and the design and construction team reach an early commitment to
Initial cost estimates were high. Rather than eliminate photovoltaic
and solar thermal panels or the high performance envelope, the façade
was simplified with a reduced amount of glazing. These adjustments
kept the cost in line with other libraries that did not achieve ZNE.
THROUGH INTEGRATED DESIGN, the design team was able to maximize
the renewable energy generation. Though only a one-story building, the
building’s height was raised to reduce the roof shading from an adjacent
three-story building. The roof design became a major focus of the integrated process, meeting the needs for solar panels, natural ventilation
The team sought natural ventilation while also protecting the building
interior from truck noise and exhaust fumes. The solution was a wind
chimney, pulling fresh air into and across the building from the side not
To take advantage of the Bay Area’s temperate climate, the design
team established a mixed-mode system that minimized the needs for
active heating and cooling systems.
SINCE OCCUPANCY, the author found that it is crucial for ZNE projects
to include adequate funding for measuring, evaluating and responding
to the performance data. Also, she points out the challenges of complex
systems in dealing with unpredictable user behavior and scheduling
Still, she writes, the library has succeeded well beyond its original
program requirements. And it has become “an inspiring center of its
