AIM Associates is the leader
of the Green Team of High Performance
School (HPS) consultants for the Petaluma
City School District. We started our input
at the beginning of the Schematic Design Phase
That early involvement allowed several major
accomplishments. The site layout of the buildings
was changed during the first site plan review
from a layout based on the street grid which is
forty-five degrees from north. Since it was early
in the process the architect agreed to a new layout
with true north/south facing of glazing. The daylighting
model testing and energy use simulations of a
typical classroom led to classrooms designed to
be so energy efficient and comfortable that a
mechanical air conditioning system will not be
necessary (CA climate zone 2). Daylight harvesting
will save about 45% of lighting energy cost.
The Multi-Use Room and Gym have very high
ventilation rates because of the high occupancy
loads. Passive down draft cool towers utilizing
evaporative cooling will make those spaces quite
comfortable even when it is 100 degrees outside.
Solar heated air that would have saved 30% of
the heating cost with a eight year pay back was
rejected by the A/E because it would have affected
the building appearance and required a redesign
of the HVAC Schematic Design.
The full campus energy is predicted to be
35% better than T24-2001, as confirmed by
the PG&E Savings By Design Program.
Indoor air quality is being improved by the carefull
selection of materials and specification of construction
procedures. We are using CHPS (The Collaborative
for High Performance School) criteria to address
the many other HPS issues from storm water management
to good acoustics.
