BIM was also important in making sure all the equipment, piping, and accessories would ﬁt into the space.
The phasing construction documents also helped the
contractor during bidding to understand that the system
could not be shut down for an extended period of time.
The engineer and the owner carefully worked through
the schedule for each phase and shutdown. All of the

shutdowns and phases were printed on the construction documents
with dates for each. As a result, all of the bids were within $100,000.
The project was very successful. All of the shutdowns were completed in less time than anticipated. The contractors knew exactly
what needed to be done during each phase. Air-handling units were
able to be operated in economizer mode while still maintaining the
proper temperature and humidity in the patient rooms.
The existing chiller plant was controlled manually at each piece of equipment. The computer graphics of the
system were for viewing temperatures
and monitoring only. Most of the existing controllers and actuators had failed.
As part of the project, the controls for
the facility were upgraded to the new
version with BACnet® capabilities. All
control points can now be viewed from
the workstation. The control system is
now fully automated. The plant operators can view and operate the system
from home over the Internet. Since the
chillers were purchased with an extended warranty plan, the required maintenance had been reduced. The addition of
the PVC jacketing on the systems makes
it easier to keep the facility clean. All of
the valves in the plant have new valve
tags that correspond to a valve schedule
and the associated ﬂoor plan. These tags
make it easier to maintain the system.
The total project cost was $2.5 million. Both Chillers 1 and 2 were at the
end of their life. Assuming that both
chillers needed to be replaced, the only
additional capital cost for the project
was upgrading Chiller 1 from a standard
centrifugal chiller to a heat pump chiller. The difference in cost between these
two chillers is $450,000. The utility cost
for 2009 was $2,084,200. The utility
cost for 2010 was $1,814,009. The utility cost savings from 2009 to 2010 was
$270,191. Dividing the added chiller
cost by the savings yields $450,000/
$270,191 = 1.665 years of simple payback.
This project reduces risk to the environment by replacing the original
R-12 chillers with R-134a refrigerant
for Chiller 1 and R-123 refrigerant for
Chiller 2. A refrigerant monitoring system was also installed as required by
ASHRAE Standard 15. In 2009, the
hospital produced 5,413 tons of CO2.
The total tons of CO2 in 2011 were reduced to 2,025.
