4 Section 9 Building Management and Information Systems and Automatic Controls PART A BUILDING AUTOMATION SYSTEM 9.1 INTRODUCTION RMIT University considers Building Automation Systems (BAS) to be an integral part of its building infrastructure. It plays a major role in the comfort of occupants, the support of specialised services and the amount of natural resources consumed by the building. RMIT requires the installed BAS to meet the following requirements: Communicate via the BACnet communications protocol for the provision of multiple automatic control vendors and competitive tendering. Common naming, information and display conventions amongst buildings. Be functional for the many different stakeholders who may use the system, including: Property Services staff, for asset preservation, problem diagnostics and resource consumption management; Laboratory staff, for monitoring of electrical and mechanical services to specialist areas; and Occupants, for snapshot of temperature conditions within their local area to confirm if the system is working properly REQUIREMENTS The requirements are to provide RMIT with the ability to have Remote Supervisory Access and Control of all automatic controls (connected). Provide graphical representation of automatic controlled building services. Graphical representation shall be simple and overview focused initially and allow for further information to be gathered by linking to more detailed pages. Include available CAD drawings of duct work for floor plans on graphics. Clearly depict the equipment with the associated BACnet Objects displayed as currently configured. Graphics shall include provision for trends of all statuses, analogue valves, time schedules and graphical access buttons for easy of movement throughout the graphics. Depiction of outside air temperature and fire alarm shall be displayed on the front page of each building INTEGRATION WITH NON BAS SYSTEMS RMIT University endeavour to integrate the BAS with other non BAS systems. The following are some of the systems RMIT endeavour to integrate the BAS with: BEIMS, RMIT s Maintenance Work order request program, for configuring an alarm to a BEIMS work order request. Alarm handling is required to be sophisticated enough to ensure false alarms and unnecessary alarms are minimised. Syllabus Plus, RMIT s time tabling system, to allow mechanical heating and cooling system to pre-cool or pre-heat the room for occupation DOCUMENTATION RMIT require Operating & Maintenance Manuals for all services to be submitted in electronic copy in PDF format (in conjunction with the hard copies) to be retained on the BAS server. For all projects the services relating to the BAS (mechanical, electrical, hydraulic, etc.) are to be retained on the BAS. Access to the documentation is via the BAS graphics that are part of these services. Design Standards Brief Section 13 Page 4 Issue No. 6, 2009

54 Section 9 Building Management and Information Systems and Automatic Controls APPENDIX 9.G The above tuning page indicates a representation of a tuning page. Page to also include the following. 1. Integral Gain should state Integral action (with the value being in repeats per minute) 2. Derivative should state Derivative action (with the value being in minutes) 3. Valve Overrides should state Manual Override, clicking on the display box on the right of the position, should toggle between automatic and manual. When on manual the valve position display should change to reverse video and allow a value to be entered from the keyboard, pressing the return key will send the entered value to the valve. This action and the ability to change any of the PID values would be password protected. 4. When on manual control the controller must have the ability to track the manual signal so as to prevent the integral action from accumulating (winding up), this will then give a bump-less transfer when transferring back to automatic control. 5. Make provision for tuning at 1 second intervals for upto 60 minutes and then be able to revert back to 1 minute intervals (or any other interval greater than 1 second upto 5 hours). Also include change of state recording of value changes. Design Standards Brief Section 13 Page 54 Issue No. 6, 2009
