Division 17 - Central Control and Monitoring System 17.01 Central Control & Monitoring System (CCMS)

     The Department of Operations and Maintenance at the University
     of Maryland College Park operates a Campus-wide Central
     Control & Monitoring System (CCMS).  Installation of a system
     that interfaces with the central equipment on the College Park
     campus of the University of Maryland are required.  The CCMS
     system must be an extension of the campus system and not an
     independent system.  This system is used to override local
     building control systems, but  does not replace them. 
     Therefore, a complete local (stand alone) system must be
     provided and integrated with the CCMS.  Connection to the
     College Park CCMS can be achieved via modem and phone lines.

     The scope of the CCMS design shall incorporate the operating
     characteristics for the proposed facility with regard to the
     capabilities of the existing CCMS, resulting in an optimally
     designed CCMS in terms of effectiveness and cost.  The guiding
     principles for this design are to provide metering (and
     submetering by campus department as feasible) for all
     utilities; to provide remote start/stop and reset for all HVAC
     systems and other major equipment; to monitor energy-using
     systems for actual loads and conditions and all systems for
     alarm status and critical malfunctions.  The desired CCMS
     shall provide surveillance and optimal operation of the HVAC
     and other systems and provide metering information as to
     actual utility usage.

     CCMS is a microprocessor based, Environmental Management and
     Control System (EMCS) which uses a distributed processing
     architecture to achieve a high degree of system efficiency and
     reliability.  It is an extension of the owner-provided Staefa
     Control System (SCS) Phoenix/System II model CCMS system.

     Systems' requirements include:

     A.   The system design and architecture shall be compatible
          with the existing CCMS campus system.  The system shall
          be designed and the equipment shall be selected to
          achieve the highest possible system wide reliability,
          serviceability, maintainability, and provide flexibility
          to meet both current sequences of operation and any
          anticipated future needs.  Specific directions of
          approach are presently being developed.
     
     B.   A digital communication line connection shall be made
          between the existing owner-provided CCMS and the CCMS
          extension within a facility.

     C.   Supervisory remote control and monitoring of the system
          is accomplished through the CCMS unit which has an
          intelligent, stand-alone capability.  The EMS/CCMS system
          will digitally communicate with stand-alone
          microprocessor-based DDC controllers installed in
          controlpanels associated with each mechanical system
          including the air handling units and the chilled and
          heating hot water systems.  The CCMS will also
          communicate with stand-alone microprocessor-based
          controllers installed at each peripheral or terminal
          mounted equipment affecting a building's environment.

     D.   Control of equipment will be direct digital control DDC
          with electric and electronic actuation.  Power actuation
          for isolation valves, two position in design, shall use
          pneumatic pressure (30 psig).

     Director of Operations & Maintenance shall be contacted in
     order to obtain the present capabilities of the CCMS and to
     provide the University with a plan for the energy efficient
     operation of the HVAC systems.  This plan shall be coordinated
     with the life cycle costing and HVAC load analysis in the
     Energy and Energy Analysis section to produce the most energy
     efficient facility design.  It shall also delineate the scope
     of control between local controls, CCMS override control and
     fail-safe arrangements by HVAC systems.

     Provisions shall be made for the complete system installation,
     including:

     A.   All sensors, contacts, equipment, and system interfaces
          and metering points.

     B.   All electrical and mechanical interface to the building
          systems and equipment.

     C.   All electrical and mechanical system components required
          by the CCMS.

     D.   Interfacing the new building CCMS to the existing CCMS
          central equipment.  This includes all necessary
          alterations to the central processing units and their
          software routines located in the Service Building (003)
          on the UMCP Campus.

     E.   Extension of underground duct bank and communication
          cables from the existing CCMS to the proposed facility.

     The Department of Architecture, Engineering & Construction
     (DAEC) in conjunction with Facilities Management (FM) is
     evaluating both the process and procedures to conduct Building
     Commissioning as well as the method for contracting for these
     services.  Until this effort has been completed and approved
     by the UMCP, DAEC will identify the applicable scope of
     services.
