A loyal client since 1994, Public Works & Government Services Canada (PWGSC) has looked to ESAC for its integration needs.  Located in Ottawa, the nation's capitol, PWGSC has installed integrated SCADA solutions in two of its large institutions.  Our goal to make the design right the first time has allowed PWGSC to use existing projects in future endeavours.  When expansion is required, an ESAC system will ensure that you do not waste the money you've already spent.

Confederation Heights

The Confederation Heights project involves the monitoring of the Central Heating and Cooling Plant (CHCP) and 12 buildings usage of electrical power, high temperature hot water, and chilled water.  ESAC develops highly reliable, fault-tolerant communication systems to consolidate the data coming from each building.  ESAC also employs redundancy allowing the individual devices in each building to retain all necessary data in case communication is temporarily lost.  Upon reconnection, the system automatically obtains the most recent information from the device. Operators of the complex are now able to monitor all hot and cold water as well as electrical usage for the heating plant.  Real-time data values are displayed on the operators PC making it easy to view the entire plant from one location.  Operators are also notified of any alarms in the system as soon as they occur to avoid costly failures. Equipped with the ESAC Reporting module, management of the Confederation Heights complex has access to totals that allow them to decide future courses of action.  At any point, a few clicks can generate daily, weekly, monthly, or yearly totals.

Tunney's Pasture

A project dating back as far as 1994, Tunney's Pasture involved the integration of their Central Heating and Cooling Plant (CHCP) DCS and 20 individual buildings.  The data from each building has the functionality of being viewed at any of four distributed view nodes.  As with any of ESAC's projects, a wide variety of real-time and historical trend screens are available as shown.  Reporting was also configured so that management can concern themselves with only the big picture. With the moderately large amount of data to be acquired from the field, ESAC developed a communication system reliable enough to accurately poll each of the monitoring devices in a short amount of time.  Operators continually have the ability to view communication diagrams, readings, and status indicators.
