Prepared: March 2000 / PANORAMA System Architecture for SC ELECTRIC

This document provides a short schematic system architecture and proposed layout for a campus of 15 buildings for SC Electric, using the Teletrol INTEGRATOR Building Automation system (BAS) and the PANORAMA Human Machine Interface software. Teletrol: Innovation, Standards... Interoperability Beyond the inherent precise control possible with a modern BAS, this project will provide the ability to collect and archive energy and electrical consumption data to be used for SC Electric company-wide energy management programs and aggregated energy purchases. The project will provide the ability to view and monitor HVAC system performance or override the BAS controls in any of the campus facilities from a centralized location or from any PANORAMA PC in any of the buildings. This feature promotes more efficient use of maintenance personnel time and resources, while maintaining a more consistent, comfortable and productive work environment.

In the early 1980’s, Los Angeles County established a building and a system to provide centralized monitoring and control of a large number of the over 1,200 County owned and managed facilities. REFERENCE Project : Los Angeles County Teletrol Installation The Building Energy Automation Systems (BEAS) project used small mainframe computers, connected to “data gathering panels” at the various buildings via dedicated leased lines. The system provided remote monitoring and exercised some degree of “overlay” or supervisory control and scheduling over the “traditional” pneumatic systems which performed the actual HVAC loop control. The NEW Teletrol / Panorama project takes advantage of LA County’s updated fiber optic cable Wide Area Network which interconnects all of the County’s owned and managed buildings. The main focus of the project is to save money via the elimination of the expensive lease lines, the implementation of intelligent energy management and rule-based system alarms, and the use of system generated predictive and preventive maintenance routines.

This project is similar in concept and scope to the LA County BEAS project, albeit in an industrial office and manufacturing campus setting with fewer buildings. Each building will have an autonomous building automation system. The project would interconnect the PC’s which monitor the building automation systems by using the SC Electric company-wide campus Ethernet LAN. This provides both centralized and distributed system monitoring and viewing capabilities, as well as data archiving and alarm logging of all connected HVAC and building automation systems. Because the proposed Teletrol / Panorama system follows well-defined Information Technology standards and protocols, it can make good use of the company “Enterprise-Wide Network” (EWN), without conflicting with other software or PC’s on the system.
