Public Works & Government
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 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
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.
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
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
