Energy Reduction:
Rather than meet the cooling load for the Final
Assembly and Body Shop buildings through the use of mechanical
equipment sized for peak demand, the chiller component of the
project evolved into a sustainable thermal storage chiller that used
a 1.3 million gallon storage tank. Incorporating the water storage
tank into the building allowed water within the tank to be cooled at
a steady rate that would be drawn against as required. The high
periods of cooling demands were satisfied by thermally stored cool
water rather than through the operation of equipment running at peak
periods. As the engineering design moved to a sustainable
perspective, it provided a business case that resulted in less
equipment with lower capital expenditure and lower energy
utilization.
According to Bill Newman of Arcadis-Giffels:
“When the decision was made to air temper the Dearborn Truck Plant,
the selection of combined chillers and chilled water storage, over
the conventional chiller-only system allows for continuous energy
savings by base loading the chillers. This means operating them more
efficiently around the clock by storing the unused chilled water
during off peak hours for use during peak hours. The Truck Plant’s
Campus had a large enough cooling capacity to allow for the
economical use of chillers with chilled water storage, thereby
saving money not only on the first cost but also on the yearly
operating energy and maintenance costs of the system.

Environmental Quality for Occupants:
The interior environments, the working areas,
were just as demanding as systems relating to the exterior. For
sustainability to be viable, provisions were needed for a positive
and healthy work environment. Human comfort issues include the
introduction of daylight into large percentage of all building areas
including manufacturing spaces. Day lighting was provided through
monitors, skylights and specially placed windows. A positive sense
of open space within a light-filled environment tends to positively
impact worker productivity. The use of non-toxic and low emissive
materials and finishes were added to the projects specification. It
was difficult to place a construction life-cycle cost analysis to
the “soft” environmental benefits for the occupants.

According to William Kroczolowski of Arcdis
Giffels: “At the beginning of the project, whenever presentations
were made to the employees about what the new Dearborn Truck Plant
might look like, the dominant attitude of the workers was; sure we
have heard all of this before, but nothing ever changed. As the
scope of the projects progressed from big to small to definitive
detail, the attitude of the workers changed as well. Suddenly, they
were reading about the new Dearborn Truck Plant in the Ford Rouge
Connection, a regularly published magazine about the news and
construction happening at their site. The Truck Plant credibility
leaped from rumor to Our Future. The employees’ interest in the
project increased proportionally. It was during this time frame that
Arcadis Giffels started receiving requests from the more experienced
employees asking how they might help during the design process. The
message received was that Ford Motor Co. had provided their families
with a tremendous life style, and as they prepared for their
upcoming retirements, they wanted to repay the company in some way.
They wanted to leave behind a small legacy of themselves at the
Rouge.It was obvious that this was important to them. While not all
of their suggestions were feasible, we listened to them all. The
ideas that reflected the “Remember and protect the past” goal
established early on during this project were incorporated in some
way. The Commemorative Wall and Plaza, Powerhouse memorial, Employee
Walkway to DTP Assembly, to name a few, all include design elements
by employees from memories of their, or their families’ time at the
Rouge.
The greatest pleasure an architect can achieve
is to see their concepts and ideas transformed into a three
dimensional reality. That pleasure is compounded when the users of
the building approach the designers, and thank them for what their
efforts have accomplished. Again and again, their message is
consistent. The “Thank You” being offered is not on their behalf,
but on behalf of the future generations of employees who will work
at the Dearborn Truck Plant but “won’t have to do it under the same
conditions that we had to”. In some small way, while remembering
the past, a foundation has been laid for a solid future. Thirty
years from now, one cannot help but wonder what today’s “next
generation” of workers will remember of their work life and how it
will relate to their predecessors’ recollections.” |
