cial kitchens are afterburners for energy use-primarily because of
the exhaust hoods-but commercial laundry facilities are even worse.
The solution for the kitchen exhaust is dedicated makeup-air fans
calibrated to the exhaust fans. Maintaining consistent pressure and
controlling the airflow is a key to passive building.
In the laundry, ozone cold-water washers eliminate heating water
from the process and also remove the chemicals from the waste
stream.
Another big challenge was that the new administration building
had to share a common atmosphere with the nursing home. There's
no way in the world it can ever be made airtight," Rodell said. The
solution was to compartmentalize the air barrier. Three different
buildings were built under a single roof. "We let the corridors, the
circulation systems, and the stairwells become part of the common
atmosphere of the nursing home. You don't know it, but when you
step from the hall into the administrative offices, you are actually
stepping into a different environment," he said.
The kitchen and laundry facilities are a self-contained building;

these extreme exhaust hoods require calibrated makeup air.

the administrative offices are another. Additional office space for a
home-health business is the third building under the common roof.
All three share a thermal envelope and a roof, but the interior buildings are compartmentalized with an air-barrier system. "That allowed
us to add a passive-house facility onto a non-passive house facility,"
Rodell said
CURVE BALL

Rodell uses a design scenario from this building that serves as an
excellent example of not knowing what you don't know and the
deeply ingrained inertia that litters the path to the high-performance
building. In the basement of the boarding home is space where heat
pumps use warm air to heat water with cool air as a byproduct. In an
adjacent space, computer servers are humming, heating the area and
using extra energy to power their internal cooling fans.
The design team initially missed the synergy because "...it is hard
to acclimate yourself to understanding how significant little things
are inside a high-performance building. Like how the distribution of
water lines can challenge you with cooling-or help you with heating." Intuition, Rodell says, can act as a mask "...before you recognize
that those computers can be heating the water, and those showers can
be cooling the computers."
"As an architect, to suddenly learn that everything I knew was
wrong," was surprising, Rodell said. "You can't unlearn this stuff, and
once you're aware of it, everything around you seems-negligent." He
doesn't blame negligence on people who don't know what they don't

struction sector, passive building is so foreign to so many. CA

One of the first questions asked by architects and designers about
this kind of construction relates to payback or return on investment
(ROI). But ROI presumes an initial investment. Because there was no
additional investment beyond what was in the budget, the ROI is either spectacular or irrelevant. "This particular company is not a
non-profit, but they act like it," Rodell said. "So, that wash of funding
has allowed them to improve the services they offer their residents."
DESIGN CHALLENGES

The main design challenges for the administration building were the
commercial kitchen and the commercial laundry facility. Commer50
