d. Survey sheets. Survey sheets included in Appendix D, or similar survey sheets will be used to
collect the necessary information for calculating savings and costs to implement a UMCS.
6. APPLICATIONS PROGRAM SELECTION. Applications programs will be selected for each system
from the survey data. A summary of applications programs discussed in Chapter 7 that can be applied to
mechanical and electrical systems can be seen in Table 12-1 at the end of this chapter.
a. Other applications to be considered for specific systems include the following:
(1)
Heating/Cooling operation monitoring.
(2)
Variable air volume control.
(3)
Air distribution terminal unit control.
(4)
Hot water distribution.
(5)
Domestic hot water generator control.
(6)
Site water distribution.
(7)
Lighting control.
(8)
Water treatment system monitoring.
(9)
Sewage system control.
(10) Cold/Ice storage systems control.
(11) Heating recovery boiler efficiency monitoring.
(12) Gas turbine generator efficiency monitoring.
(13) Cogeneration unit efficiency monitoring.
7. REPAIR AND REPLACEMENT (EXISTING EQUIPMENT). Equipment and accessories required to
provide building environmental conditions or process support must be in good operating condition.
During UMCS operation, existing local loop control equipment (for supervisory control implementation)
and actuators must be operational in order for the UMCS to perform its necessary functions.
Furthermore, during UMCS failure, the existing local loop controls must continue to function (for
supervisory control). The existing control devices that must be repaired or replaced as determined by
visual inspection and operational check will be noted during the survey. The cost to perform this work will
be estimated for each building for future use in determining budget contingencies and operating and
maintenance budget requirements.
8.
IDENTIFICATION OF EQUIPMENT MODIFICATIONS.
a. The implementation of UMCS requires mechanical and electrical equipment modifications. The
modifications will be identified during the survey in sufficient detail to estimate their cost.
b. The cost of the mechanical and electrical modifications required for each building will be
determined and used in preparing the cost estimate.
9. I/O POINT SELECTION ESTIMATE. The control diagrams for each system described in chapters 8
and 9 provide the starting point from which to determine the required number of points for each system.
The number of I/O points, and associated UMCS instrumentation and controls costs for each system, will
be identified and used in preparing the cost estimate.
