Benefits of IELVS IBMS

The Traditional Approach

Imagine an office where each department; management, accounts, production, sales,engineering, HR all ran different software packages operating on different computer networks.Any time you had to share information or generate a report, various people would have to passdocuments around either on paper or using a memory stick. Data would have to be reentered,imported or converted. Nothing would line up and key information would be spread acrossmultiple systems.

This sounds ridiculous, but this is the approach that is used when installing control systems inbuildings. Each control system; BMS, security, lighting, metering, electrical, lift controls,generators, hydraulics, etc. are supplied and installed as separate, standalone systems.

These control systems are often referred to as Extra Low Voltage or ELV systems as theyoperate at voltages less than 48 volts over data cables.

Facility managers need to learn every ELV system and somehow pull together the informationneeded in order to operate each system. Operators are required to log into and run eachsystem separately to monitor and control the facality.

Each ELV system will have its own workstation, software applications and login passwords tomanage functions such as graphic displays, trends, reports, alarms, schedules and historicaldata storage. Some systems can only supply some of these functions. In fact, some systemscan’t provide any of these functions at all.

Traditional ELV Implementation with different workstations and networksIf data from one ELV system is required by another ELV system, it is solved by either:

a . Developing a “oneoff” High Level Interfaces (HLIs) – complex, custombuilt software and



hardware to transfer limited data back/forward to each system; or

b. Connect via low level interface using hard wired relays and multiple cables to connectcontrollers together.

High level interfaces are expensive, difficult to maintain and often fail if either system has to beupgraded or changed.

Low level interfaces are also expensive to install and you are charged twice by two suppliers toconnect one wire. They can only pass limited information so they tend to be used for limitedpurposes (eg. alarms and status).

The ongoing management of changes and additions for either interface is cumbersome andexpensive.

What is an IELVS?

An Integrated Extra Low Voltage System (IELVS) is a new approach to designing andintegrating the disparate control systems in a facility to improve the operation of that facility.

IELVS ensures every system connected communicates and shares all of its data via an industrystandard open protocol. IELVS also ensures the data collected from every system is madeavailable for other client application to use.

IELVS supplies an independent user interface that monitors and controls every system from acentral location and over the web, as opposed to a traditional path of multiple workstations withdifferent logins and applications.

One set of graphics for all systems.One alarm console to display, acknowledge and dispatch alarms from all systems.One set of time schedules used by all systems.

One data storage area for all historical data for trending and reporting for every system.

IELVS – Consolidated, consistent and simplified

How Does it Work?

The primary design principles of an IELVS are Open Communications and Open Data.

IELVS works by obtaining data using multiple industry standard open protocols. This data isused within IELVS and can also be exposed for other applications to use. IELVS communicatesdirectly to field devices, plant equipment and open gateways into each system to obtain, store,diagnose, display and expose data from each system.



An IELVS design also uses a single network to connect all systems together. The network isinstalled by a certified contractor using industry standard equipment. The consolidation ofnetworks removes the expense of separate networks being installed by each systemcontractor. The IELVS contractor becomes the single point for all network management,connectivity, security and provides the servers or virtual servers for all contractors to use.

IELVS Implementation with single network and no workstationsTraditionally, all data from each system is either not available or stops at a proprietary BMS. AnIELVS solution makes the data available as live, real time values or historical records. Thisallows clients to freely choose different applications that are fit for purpose. Open data allowsapplications such as maintenance packages to obtain information about equipment such asruntimes, alarms and warnings to aid with predictive maintenance options. Energy applicationshave access to all meters and ambient conditions for detailed reporting. Client specificapplications can be used to monitor key performance indicators in real time.

IELVS – Open Communications and Open DataThe Open Data principle simplifies the integration of other applications that need to access datafrom any ELV systems. These applications could include:

Tenant Web PortalsAfter Hours Booking and Scheduling SystemsRoom Scheduling SystemsRemote monitoring, maintenance and repair of systemsEnergy ManagementNABERS ReportingMaintenance and Asset ManagementAdvanced Fault Detection and DiagnosticsPredicative Maintenance Scheduling



Energy and Performance Diagnostics

The Open Communications principle allows the installation of different systems for the samearea. Expansions, upgrades and variations can be supplied from different suppliers allowing acompetitive tender process to take place. Since the communications to each system isgoverned by industry standard protocols, to IELVS, there will be are no differences betweensystems.

Open Communications, Open Data, relies on open and documented formats, standards andspecifications and avoids all closed proprietary formats that carry the risk of becomingobsolete. New systems that become available in the future will be able to integrate into anIELVS design because of the specified open standards.

Features and Benefits

IELVS becomes the ‘eyes and ears’ of a facility and provides the single operator interface toview information collected and has the means of being able to adjust and manage, improvingoperational efficiency and safety.

An IELVS design minimises the duplication of graphics, trending, reporting, scheduling, datastorage, software, management functions, network equipment and cabling. An IELVS designeliminates the need for any workstations. Operators access IELVS using their standard webbrowser on their work or home computer and are presented with a consistent, consolidated andsimple user interface.

The major features of an IELVS design are:

Specifies an open architecture that uses open and documented formats, standards andspecifications and avoids closed proprietary formats that lock a client into a single vendor.Specifies certified network installation based on industry standard equipment.An IELVS design allows the installation of different ELV systems for the same function in onefacility (e.g. Different airconditioning control or DDC systems, different lighting systems). Expansions, upgrades and new systems can be supplied from different suppliers andintegrated into the one IELVS.Provides a consolidated environment for all live and historical data storage from all controlsystems maximising the ability to report, trend and diagnose the facilities operatingperformance and energy usage.Provides a single web interface into all systems for all operators. Being web based solutionintranet and/or internet access can be enabled for all users. Web access can be givenduring construction, implementation and commissioning providing an overview of eachsystems progress.An independent layer to validate the commissioning and operations of each control system.

Some of the main features and benefits of an IELVS include:



Features Benefits of an IELVS

Single User Interface forall systems

Easier to maintain and upgrade.Faster troubleshooting.Commissioning and verification of all ELV systems beingmonitored.

Web based UserInterface

Easy access to anyone with authority. Less Training costs. Minimal cost to give access to tenants and other users.Simplifies remote access.No Workstations.

Simplify Operations One alarm console to unify alarms from every ELV system,including network equipment. There is no longer the requirementto log into multiple systems to see and acknowledge alarms.One set of graphic pages displayed using standard WEBbrowsers. ELV system providers no longer need to supplyseparate graphic pages which reduces their overall costs.Time schedules and holiday assignments are centralised and setfrom one location.Information from multiple systems can be combined on trends,reports and graphics.

Open Design based onOpen Technology

A future proof facility

Avoids being locked into original suppliers. Expansions, upgrades and maintenance can be put out tocompetitive bidding.Reduces fit out costs.

Consolidated equipmentrequirements (hardware,software, networks andcabling)

ELV suppliers can reduce their scope by omitting commonfeatures such as graphic pages, trends, reports, front endequipment, storage devices and vertical cabling and networkequipment. Initial capital reductions that fund the IELVS Ongoing life cycle cost savings.All ICT equipment can be serviced by an experienced contractor.

Common open databasefor gathering informationand reporting

All the facilities historical data is stored in a single location for allsystems.Improved response to faults and problems.



Improves productivity of facility management team.Provide quality information and reports to management, facilityowners and tenants.Easier to generate new income streams from tenants.Improved compliance monitoring of essential services (fire,emergency lighting, etc).Ability to pass data from one system to another. Ability to mix and match trends and reports from multiple ELVsystems.Provide a platform to encourage clever strategies for reducingconsumption by integrating the functionality of previouslyseparate ELV systems. Simplifies the implementation of advanced fault diagnostics andpredictive maintenance strategies

Single source for allEnergy EfficiencyReporting

Improve NABERS ratings.Reduced operating costs.Single reporting platform for monitoring energy targets forNABERS.

Independent overviewand validation of ELVsystems.

Because the IELVS is not a part of any ELV system, it offers anindependent means for verifying the operation of all the ELVsystems. This can greatly improve commissioning and ongoingfault identification when the facility is operating.

Conclusion

We believe that providing a fully open IELVS the end result would be a facility that is farsuperior to that normally specified and the client would have a building management systemthat is easier to use and provide more flexibility for the future. Most importantly, the clientwould be able to closely monitor, diagnose and alter the operations of the facility ensuring themost efficient performance is achieved yearonyear.
