UBC Technical GuidelinesUBC Vancouver and UBC OkanaganNovember 2021 Revision1OVERVIEW1.1.GeneralA.1.2.Section 25 05 00Building Management System (BMS) Design GuidelinesPage 4 of 60The University of British Columbia is a large campus with numerous buildings of variousages. A significant number of these buildings are of a vintage that predates modernmicroprocessor based HVAC control systems and these older building control systems arecontinuously being upgraded. New buildings are also being constructed at the UBCCampus on an on-going basis.To assist in the operation and maintenance of campus buildings, UBC Building Operationsprovide centralized monitoring and control of UBC buildings from a central location viamicroprocessor based DDC controls. To facilitate the centralized BMS monitoring andcontrol standards have been applied to the selection of BMS equipment and for theapplication of BMS installations in buildings. The UBC BMS Design Guidelines serve toidentify typical standards for the application of BMS’s in UBC buildings. These DesignGuidelines have also been developed to assist UBC in ensuring that UBC buildings areprovided with high quality BMS installations that fully meet their requirements.Application of these BMS Design GuidelinesA.This document is intended to serve as a guideline for the Design of Building ManagementSystem (BMS) installations in buildings at the University of British Columbia (UBC). Theguideline serves to generally identify the existing UBC Campus BMS infrastructure andinstalled components and to record BMS design requirements specific to UBC installations.The UBC Design Guidelines may be used by BMS Designers for guidance in the design ofUBC BMS installations but shall not be reproduced, in whole, or part, for inclusion in BMSDesign Specifications, or Tender or Contract Documents. The UBC BMS Design Guidelinesare not Design Specifications and do not include sufficient detail to be used as such. BMSDesigners will be required to include additional detailed information in BMS DesignSpecifications to clearly identify all aspects of the BMS installation.B.BMS Designs shall be based on sound industry standard practices. BMS Designers shallprovide BMS Designs that have been specifically engineered for the application and shallexercise discretion in the application of these guidelines. All new building construction atUBC will utilize DDC BMS monitoring and control of building equipment and systems tosome degree. Existing buildings are also being upgraded with retrofits to mechanical andelectrical systems as well as to the building control and monitoring facilities. BMS DesignDocuments shall clearly identify the nature of the BMS installation work and shall includethe contractual documentation and requirements where applicable.C.All new BMS installations shall comprise equipment, data and data communications thatare fully compliant with ANSI/ASHRAE Standard 135-2001 “BACnet” and Division27Section 27 05 08 – 1.4.8.1.Legacy equipment manufactured by JCI and SBT that are not compliant withANSI/ASHRAE Standard 135-2001 shall NOT be used for NEW BMS installations.2.Equipment installed on extensions of a BMS using non-BACnet legacy equipment,manufactured by JCI and SBT, shall have the capability of directly communicating tothe legacy equipment in the proprietary communications protocol as well ascommunicating with BACnet devices. New equipment that does not have thecapability to communicate in both the proprietary protocol and BACnet is placedonto a legacy system; the device shall use the BACnet communications protocol.When equipment capable of communicating only with BACnet is placed onto an
UBC Technical GuidelinesUBC Vancouver and UBC OkanaganNovember 2021 RevisionSection 25 05 00Building Management System (BMS) Design GuidelinesPage 5 of 60existing legacy system, a communication gateway device shall be placed on to theproprietary network. The gateway shall bridge the two disparate communicationprotocols and act as a translator that allows bilateral communication between theBACnet compliant devices and devices communicating using proprietarycommunication protocols.1.3.List of AbbreviationsA.The following are a list of abbreviations used throughout these design guidelines andare also abbreviations used by the University of British Columbia relating to BuildingManagement Systems.ANSI ASC ASHRAE -American National Standards InstituteApplication Specific ControllerAmerican Society of Heating, Refrigerating and AirConditioning EngineersASTM AWG B-AWS -American Society for Testing MaterialsAmerican Wire GaugeBACnet Advanced Operator Workstation: The B-AWS is the advancedoperator's window into a BACnet system.

The networkcommunications is accomplished using a 3-wire, 18 gauge, RS-485 platform.The newer JCI installations utilize BACnet data communications over a MSTPnetwork that operates across a 3-wire, 22 gauge RS- 485 platform. The BMSprimary communication networks within buildings are dedicated BMS networksegments and are not shared with other building data communications.The same network topology indicated above is used for, dedicated Field Levelcommunications network (labelled the “Floor Network”) for communicationbetween ASC’s and between ASC’s and DCP’s.

The Management Level communications network utilizes coppertelephone grade cable between the remote buildings and the UBC telephonecentral exchange in the Henry Angus Building. Signal conditioning and networkinterface equipment is required to transmit the data communications via thetelephone grade lines. There are four SBT Apogee primary communicationnetwork segments at the UBC campus. All of the network segments areconnected to the SBT Apogee Server. Individual building BMS’s areinterconnected to one of the network segments based on a number of criteriaincluding the building geographical location.b.There are a number of newer SBT Apogee building installations that utilize TCP/IPEthernet data communications over the UBC campus enterprise EthernetNetwork for communication between the remote building BMS installations andthe central monitoring and control equipment. The dedicated standalone BMSnetwork is interconnected to the UBC Campus Enterprise Network at a locationwithin the building.
