One Sightsolutions through their attitude towards providing ‘open’ solutions were able to assist the University in getting a system in place that could provide interfacing for all systems that are currently being deployed in new and renovated buildings across the Campus today. This was accomplished by listening to the requests of the University for implementing a system that would allow an infrastructure to be deployed that encompassed all areas of control and monitoring across the entire Campus.
Niagara AX was chosen as it had the proprietary driver available to connect to the installed BMS system in all buildings. This allowed for a seamless upgrade to achieve web access to University personnel to view and change specific requirements within the portfolio of buildings. The fact that Niagara was deployed across the buildings also assisted in providing data collection for many electricity and energy meters around the site. As we have found very popular, the addition of the oBIX interface to an eSight aM&T system provides energy control across the entire site. One Sightsolutions provided the Niagara AX and aM&T products utilized across the site …..
The University of Liverpool has always been a leader in installing products that embrace new technology within building controls systems. The University was one of the first sites in the UK to install an Ethernet backbone to connect various HVAC controllers to a common platform across the Campus, thus giving the engineering department a supervisory view of the many plant rooms via an Ethernet connected system. In the early days this was installed as an IPX interface but as technology developed, then the site upgraded to TCPIP to ensure a more modern site wide scope was adopted.
Having an IP infrastructure installed across the site has allowed the Campus to benefit from the availability of connecting to metering devices to enable the University to handle their commitments to energy reducing programs. This has been accomplished by using meters with smart interfaces such as Modbus, Mbus and Bacnet protocols. Most electricity and heat meters incorporate one of the protocols listed above and can readily be interfaced to, if selection of products is correct at the time of installation. Gas and Water meters are monitored in most circumstances with a pulse input indicating usage.
One Sightsolutions were selected to provide products that incorporated Niagara AX interfaces and hence by the coupling of AX devices that could operate on any ‘open’ protocol, the aM&T system was able to seamlessly and automatically read and store data using the IP enabled ‘oBIX’ interface from the many ‘open’ solutions that are readily available from most manufacturer’s equipment.
To this end, One Sightsolutions were contracted to supply an aM&T system to the University that was not only web deployed for ease of engineering access, but also web deployed in that the aM&T system was enabled to collect data from AX devices connected on the Universities Intranet. Strategically placed devices collect data locally from smart meters and store the values which are collected on a regular basis by the aM&T system.
The aM&T system is also able to import information direct from files supplied via utility company websites. This is very useful where metering devices have not yet been installed that allow the connection to either the Niagara AX or aM&T protocol interfaces.
The final solution has now been installed and has been operational for a few years. The growth of integrated systems across the University Campus is today benefiting massively from the initial vision deployed by both the Universities Engineering department and One Sightsolutions which put in place a system with the future of building controls and energy monitoring coupled with the interfaces that are now integrated into most manufactures equipment catered for.
