2. The BASNC is presently located in Building 2-99 at Camp Ripley.

Building Automation Systems Administrator:

Wade Sandbakken Email: wade.j.sandbakken.nfg@mail.mil Direct: 320-616-3161 Cell: 320-412-6091

G. Department of Defense, Minnesota Department of Military Affairs (DOD MN DMA) Network

1. The DOD owns and operates a dedicated mixed-mode network (fiber and copper) for building-to-building and building-to-BAS Network Center communications. The DOD MN DMA Network is responsible for network design and network device maintenance. All systems using this network need to be approved by the DOD. The DOD MN DMA Network is a protected network with limited internet connections.

2. The controls contractor shall consider the DOD MN DMA network an existing military network system to which the specific building control system will be connected.

3. All supervisory devices must communicate using BACnet/IP and must support the objects and services listed in this specification. The MN DMA is committed to integration so that point status and automatic control can be channeled into a common protocol. The MN DMA has established BACnet as the common protocol.

H. MN DMA BAS Functions

1. The general categories of the automated capabilities of the MN DMA BAS system are:

a. Monitoring and Scheduling: Includes starting, stopping, observing, and reporting the operating status of the equipment, systems, and subsystems.

mailto:wade.j.sandbakken.nfg@mail.mil

HVAC 23 09 23 - 2

b. Intervention: The ability to automatically or manually shift to an alternate operating mode from a remote location when weather or other conditions warrant it.

c. Integration: The ability to coordinate the operation of several systems within a building, or several subsystems within a system, to ensure most efficient operation.

d. Management Information: The ability to provide cumulative operating data such as system run time, units of energy consumed, and preventive maintenance schedules.

2. All vendor BAS systems must be capable of functioning in the following modes:

a. All building systems points can be monitored and commanded, including equipment scheduling, by the BASNC during work hours

b. System alarms shall be displayed and acknowledged by the BASNC during work hours I. BACnet Integration:

1. Due to the complexity and size of the MN DMA BACnet system, integration requires stringent cooperation between the BASNC and the selected temperature Controls contractor. The MN DMA requires direct communication with the manufacturer's highest level of customer support, and may need to converse with the manufacturer's BACnet development team during project design, implementation, commissioning, and warranty phases.

2. The MN DMA is committed to integrating different manufacturer’s temperature control systems on a common LAN using a master workstation for all existing and future temperature control systems that may be installed. MN DMA BACnet required conformance is limited to B-Side or BACnet building controllers, only. The temperature Controls contractor must provide labor, software, materials, wiring, fiber coordination and expertise to install the BACnet Building Controller.

3. BACnet communication shall be via the DOD directly from the supervisory controllers without having to route or convert it from a proprietary source. When supervisory network controllers are used for core BACnet communications, the field level panels on its sub LAN, such as VAVs and unitary level controllers, can utilize BACnet MS/TP.

1.03 BACNET CONFORMANCE

A. BACnet conformance disputes that may arise in the temperature control contractors installed

BACnet Building Controller will be resolved by MN DMA working directly with the temperature Controls contractor’s factory. Cost of translation between non-English speaking testers, developers and customer support personal whether overseas or in the USA will be the responsibility of the controls contractor. On site device testing will be conducted using the BACnet Manufacturers Association / BACnet Testing Laboratories (BMA/BTL) Virtual Test Shell

3.5.0 (VTS) program. Virtual Test Shell (VTS) is an application for testing the BACnet functionality of various devices used in BAS. It is available at http://sourceforge.net/projects/vts/. Conformance issue fault will be agreed on and resolved using ANSI/ASHRAE Standards 135-2016 publication.
