UNIVERSITY FACILITIES AND SERVICES

GRAPHICS STANDARD

Completed 09/5/2002

 

 

The controls installation shall conform to the University Standards and the current Building Automation System (BAS) Operational Standards, set forth by Facilities EOG and O&M divisions for the development of graphics, points and equipment nomenclature and naming conventions, and the software configuration organization. Rapidly changing technologies in controls and graphical interfaces require that this document be revised with advances and enhancements of the BAS.  The link above connects to the most recent version of the standard.  Revisions will be footnoted.

 

There are a number of basic graphics. These include:

 

1.                   System Graphic

2.                   Space Graphic

3.                   Engineering Submittal information

 A.       System Submittal Drawing.

B.               Description of Operation.

 4.        And any other graphics may be required by the specific project.

 

A more in-depth description of each graphic detail is as follows.

 

1.                  System Graphic

 

A.                 The equipment drawing will be three-dimensional.  The values on this screen shall be reported in real time as well as dynamic to be updated as the value changes.

B.                 All components of the drawing will show their actual field location and position.  Sensors will be in the exact location in reference to piping and air stream.  Icons or “library” images imported during the construction of the drawing will be accurate in depiction of the device and any interaction with other components of the drawing. i.e. do not draw piping into the motor of a pump Icon.

C.                 If there are size limitations or clutter from the number of components, a link to a sub graphic having the same layout will be used to clarify.

 

2                Space Graphic

 

1.                  Floor plan drawings will be linked to the supplying AHU or in some cases to the exhaust fan.  Electronic floor plans to be provided by Architect/Engineer or the university archives, as appropriate.

2.                  Floor plans showing areas served by more than one AHU will have the areas color-coded by AHU.  If the AHU serves different floors, the color will be consistent for an AHU for all floors.

3.                  If an area has control other than DDC, it will be noted with text and left white in the background.

4.                  A temperature zone serving more than one space shall have a unique pattern, to distinguish that zone from other temperature zones.  The patterns should slight enough as to not obscure the space temperature, room number, and borders detail but visible enough to be able to distinguish between different zones.  A different "peppering of symbols (of...... +^ * +hfsQRTYJXVNM) or patterns (hex, herringbone, verticals, etc.) will be used to define the zones.

5.                  Temperature zones dedicated to only one space will not have to be detailed.

6.                  Remote physical points such as differential monitors and the like shall be shown in their installed location.

 

B.         The second level of graphics shall be all the DDC points to be installed under the contract overlaid on building floor plan and the Air handling Unit and it’s associated systems.  Electronic floor plans to be provided by Architect/Engineer. 

 

 

3.         SUBMITTAL

1.                    This will consist of system schematic and related information as in the submittal.

2.                     

4              Description of Operation

1.      The approved description of operation will appear on a text graphic in 12-point text written in paragraph form.

2.      Additional notes may appear on the equipment graphic in an appropriate location.

5          Layout

 

A.                 The subject device of an equipment graphic will be centrally located on the drawing.

B.                 At the top center, the name of the equipment device will be displayed with its room number.  Immediately below the PM# will be displayed.  On a third line will be the capacity of the device in units common to that device. i.e. AHU’s in CFM, pumps in GPM.

C.                 The top right hand corner will contain links to associated graphics.  The Description of Operation, submittal graphic, Space graphic, and graphic index page will be typical.  Other links may be required.  All graphic pages will have a backward link to return to the main System Graphic.

D.                 The top left-hand corner will contain global data.  Outside Air would be the most common; other values may be required when related to the device operation.  If the program for this unit utilizes a global data point, then that point must be displayed on the system graphic. 

E.                  The lower left-hand corner will display the operational modes of the device.  Occupied, warm up, winterized, and economizer would be common.  Other modes will be displayed if the unit uses them.

F.                  In the upper right hand area, just below the links, the setpoints of the device will be displayed.  All set points in the various control loops of the device, DA temp, Static pressure, MA will be placed in columns as the drawing permits.

G.                 The date of the last revision of the graphic will be displayed in the lower right corner.

 

 

6.         Text

 

A.                 Text will contrast with the background for easy reading.

B.                 The text will be free floating with out borders or boxes unless specifically required.

 

7.         Reference

A.                 Attached are examples of existing graphics that meet these requirements.
