SUBJECT: Location of Cooling Towers in Future
Headquarters Building Expansion
1. As indicated in the November 1982 Master Develop-
ment Plan and Master Utility Systems Plan, the Powerplant
cooling towers are to be relocated behind the new parking
garage. Under this proposed plan, the cooling towers
would be approximately 500 feet from and out of direct
sight of the Powerplant.
2. With the future trend in this Agency towards
electronic offices and small computer centers in addition
to the expansion of central computer centers, the primary
source of chilled water for air conditioning will be the
Powerplant. Thus the reliability of operation of the
Powerplant and in particular the chillers and cooling
towers will become increasingly critical in the future.
Therefore, in light of this fact and for the following
reasons, it is recommended that the cooling tower location
be reconsidered and that they be moved closer to the
chillers in the Powerplant:
a. Cooling tower problems can show up first
as high head problems at the chillers. In trouble-
shooting these problems, maintenance personnel must
physically check both the chillers and the cooling
towers. Therefore, the response time to trouble-
shoot and correct operational problems is less with
the cooling towers located adjacent to the Powerplant
than it would be with the cooling towers located 500
feet away.
b. Remote location of the cooling towers will
make normal maintenance, routine inspection, and watch
checks more time consuming and less convenient for the
maintenance personnel which could result in the cooling
towers getting less attention than is desirable.
c. Location of the cooling towers closer to the
Powerplant will result in significant construction
cost savings since less large pipe must be installed.

Pumping costs will also be reduced somewhat due to
the lower pump head required.
3. While the significance of the factors cited in
paragraphs (a) and (b) above vary with the importance of
the particular equipment involved, the cooling towers
will be truly critical to the operation of this Agency.
Therefore, these operational and maintenance factors become
more critical to overall system reliability. Of course
these factors can be reduced in importance to the extent
that increasingly higher levels of maintenance and moni-
toring are provided at the Powerplant, something which
would probably not occur should GSA remain on site in their
present maintenance configuration.
4. Therefore, it is felt by the undersigned that
the long-term system reliability of the chiller/cooling
tower system would be decreased by locating the cooling
towers remotely from the Powerplant. Aesthetically,
placing the cooling towers behind the new parking garage
places them only 350 feet further from the new building
than their present location and still within sight of the
building. While aesthetic considerations are important,
in this case, it is felt that maximizing overall chilled
water system reliability is more important to long-term
Agency operations. Should chillers be located in the
basement of the new building, the importance of locating
their cooling towers as close to the chillers as possible
remains critical for the same reasons outlined above. If
there are any questions, please give me a call on extension
