along with the water consumed, the
preheat energy required to address
the humidifi cation latent load and
perhaps ultraviolet (UV) sterilization
for the system.
Personally, I have not seen the
specifi c confi guration you illustrate
applied in the Portland area. I did
work with some 100% OA systems
that used direct/indirect evaporative
cooling in a Seattle project a while
back.
The systems were applied to mitigate
the solar load associated with
a 20-story glass atrium and worked
well. But there was an interesting
" lesson learned. " The contrast
between the environment in the rest
of the facility-served by low temperature
air systems-and the areas
served by the evaporatively cooled
systems generated a lot of occupant
complaints even though the space
temperatures were within a degree
Fahrenheit or less of each other.
Early in my career, I saw sprayed
chilled water coils in a mushroom
farm and chilled water air washers
in a paper products plant, both of
which are similar concepts. In those
cases, the system confi guration was
driven by process requirements
rather than infection control.
A quick survey of the folks in our
company reveals that we are seeing
systems confi gured in a manner like
what you suggest serving automotive
paint booths, server rooms and
museums. All the applications were
driven by the nature of the load
rather than infection control.
Your fi nal question is a great
segue into an upcoming column.
In it, I will explore/contrast the
various normalized data sets commonly
used for energy modeling

as well as real time weather data. I
have posted spreadsheets contrasting
TMY2, TMY3, satellite-based
TMY, and real time weather data for
several sites-including Portland-
on our commissioning resources
website to support the column. You

any questions, and thanks much for
