Foundations of the 4th UtilityUsing dedicated infrastructures for different systems is a tradition that’s slow to die – now the era of new energyefficiency control systems is making the savings offered by integrated building infrastructure hard to ignore

www.systimax.com

Doing things the way they’ve always been done is a comfortable approach that leads to a false sense of securitythat everything will go well. But, for building infrastructures, sticking to tradition comes at a high price. Using separate networks for data/voice, environmental control, security surveillance or other systems canseriously damage your profits.

Application NotesDecember 2006

A study by the Building Technologies Group in the UK showed a reduction of 23 percent in capital expenditure achievedby converging IT and building systems networks. Even more important, the study reports savings of 30 percent onoperating expenses. As labor costs rise and there are demands to connect more systems via the network infrastructure,these savings will go on increasing.

Every year, building automation systems are growing in complexity. Much of this is the result of new regulations toimprove employee’s working conditions and safety. Added to this is a stream of new regulations and directives in thepipeline to make buildings ‘greener’ and more energy efficient.

Since 75 percent of a building's total lifecycle cost is operating expenses, any savings here are especially valuable. They raisenet income, improve return on investment and allow space to be let profitably at prices that ensure consistently high occupancy.

Cutting Costs and Saving the Planet

If the cost and environmental benefits of managing energy usage don’t persuade owners and developers to installimproved control systems, then new laws soon will. To comply with the Kyoto Protocol, the European Union EnergyPerformance of Building Directive became mandatory from January 2006. This requires energy performance certificationand energy demand management in all new and refurbished buildings of more than 1000m2.

Even tougher laws to reduce energy consumption and carbon dioxide emissions can be expected in the future, not only inEurope but also worldwide. In response, suppliers of building control systems are introducing sophisticated new solutions.

A common theme in these new solutions is the expanded use of IP (Internet Protocol) to enable communication betweena wide array of devices, and as we know from traditional LAN networking today, this in turn will drive the use of standardstructured cabling systems for these control systems. This makes the move to a common network and cablinginfrastructure for voice/data and building automation systems much easier.

Not only does using one high performance infrastructure to replace several dedicated ones save money today, it alsoopens the way to greater savings in the future. High quality, standards-based structured cabling will easily support growingnumbers of sensors and controllers needed by new, energy saving systems.

As additional regulations accelerate the adoption and deployment of these new building control systems, owners ofbuildings with disparate infrastructures will face performance and management problems. In contrast, well designed,high bandwidth structured cabling systems can support and be adapted to the needs of legacy control systems todaywhile in addition will meet the requirements of vital systems for 20 years or more.

SYSTIMAX® Solutions has been at the forefront of cabling development not just for network intensive systems used inthe voice and data networks of most modern enterprises, but also in testing and qualifying traditional building controland automation systems usually associated with proprietary cabling media, to operate over standard structured cabling.

Using high performance twisted-pair copper cable in horizontal connections and multimode fiber in the network backbone willsupport the wide range of a building’s IT and other services. This has become the blue-print for the ANSI/TIA/EIA-862 cablingstandard for Building Automation Systems that specifies a generic cabling system for BAS for use in commercial buildings.

While using the right cabling removes performance barriers to integration, standardizing on Ethernet interfaces and RJ45connectors is removing the practical obstacles. Many new building automation and security devices include these andcan be plugged directly into the data network.

Transforming Buildings and BusinessesAs well as lower installation and operational costs, integrated network infrastructure brings other major benefits to realestate owners and developers. The ‘network workspace’ is now as important as the physical workspace and can have a critical impact on the efficiency and productivity of businesses. As a result, many prospective tenants will have highquality connectivity near the top of their priorities when looking for a new address.

The ability to meet or exceed tenant’s infrastructure requirements is an important selling advantage for real estate.Organizations often see moving offices as an opportunity to transform their business. Offering them a workspace with the right infrastructure gives them the means to streamline processes and introduce operational efficiencies that raiseworkforce effectiveness.

The competitive edge of most businesses depends on fast information flow and efficient collaboration between employees.By delivering an advantage in these key areas, high quality cabling improves a building’s ability to attract and retain good tenants.

As well as helping transform tenants’ businesses, integrated infrastructure opens the way to move efficient propertymanagement. Services such as environmental control and security, connected via this infrastructure, are easier to monitorand manage from remote locations. Skilled staff at single control centers can ensure that buildings throughout a metropolitanarea are all functioning as they should. Using high speed communications and remote control, they can respond to problemsbefore tenants are even aware of them.

The same connections also offer other options such as outsourcing building management. With integrated high speedlinks to all its systems, both the building and its management can be more flexible. They can adapt quickly to changingeconomic conditions or market expectations to maintain high occupancy and revenues.

In contrast, the wrong connectivity can lock a building into specific uses and low rents. It can also render buildings obsoletelong before their time. Re-cabling to remedy this is not only expensive and wasteful; the property will also have to becleared while the work is done.

SYSTIMAX SCS: Infrastructure Flexibility

The Next StepsUsing one data and communications infrastructure to replace all others (with the possible exception of some fire alarmconnections) is now a practical proposition for most buildings, and is becoming known as the 4th Utility. There is usually,however, another cabling infrastructure to provide electrical equipment throughout the building with power.

Over the last 30 years, devices demanding electrical connections have multiplied even faster than those requiring networkconnections. But, recently, more and more of these devices have been types that don’t need high power or voltage.Controllers, sensors, cameras and much other equipment in building systems work with low voltage direct current.

This trend is driving another new move in network integration – the use of communication cable to supply low voltagepower. International standards for PoE (Power over Ethernet) have been ratified, and the necessary equipment is nowcommercially available. This uses conductor pairs in data cables to supply connected devices with power from powersupplies in communications closets.

While it can never replace all high voltage connections, PoE promises to reduce the amount of power cabling needed inbuildings and cut equipment installation costs. In the near future, we can expect to see a wider set of devices poweredvia their twisted pair cables.

Driven by the need to reduce energy costs and minimize heating effects, the move to cut the power consumption of officeequipment is only just beginning. Environmental pressure from within and outside the organization can only acceleratethis trend.

Growing use of energy and environmental management solutions, driven by new regulations, will also accelerate acceptanceof PoE. The large numbers of sensors essential to the new control systems may require major additions to electrical cablingin areas where the need was not previously foreseen, and the use of their network connection for both power andsignalling reduces the cabling to a single connection per device.

A bonus of eliminating high voltage electrical cables is the space saving in cable ways. This is especially valuable whenrenovating older properties where cable routing can be a major issue. If the height between floor severely limits the under-floorspace for cabling, replacing several cables with just one could tip the balance towards preserving a building rather thandemolishing it.

When deciding on network infrastructure for new or refurbished buildings, real estate businesses must look 20 years intothe future. Among the few certainties over this time are much higher energy prices and far more stringent environmentalregulations. To support the advanced building management systems these demand, major network vendors, such asCisco Systems and HP, are already developing and promoting new architectures and technology.

If they are to take advantage of the potential these offer to support multiple systems, buildings need the right cabling.Installing a high quality solution today gives buildings the foundation to adopt the new control technology essential tomeet tomorrow’s demands for ever higher business and energy efficiency.

The Route to SuccessConstruction costs for the cabling of the voice, data, and BAS can be reduced considerably when integrating the cablingand pathways. The potential for one project team to engineer, install and project manage the installation for all the cablingis extremely compelling. Trade contention is reduced, scheduling is easier and ultimately the project runs more efficiently.If something goes wrong, the customer only has to deal with one team for systems integration. The length of the overallproject for engineering and installation can also be reduced by consolidating the cabling installation.

The key is early planning. If the systems (Voice, Data, Fire, Security, HVAC, etc.) are bid and designed separately, costsfor delivering the cable will increase and flexibility will decrease. Costs can be minimized and flexibility can be increased ifpathways are shared for the various services. How the cabling is delivered to the work areas and devices will ultimatelydetermine the cost of changes and rearrangements. One integrated cabling system and cable pathway can be implemented,versus five or six individual cabling systems and pathways.

Moves, changes, rearrangements and upgrades can be performed more cost effectively, with potential savings for materialand labor when using a structured cabling approach. There is less disruption to the work environment, which also affectsthe cost and performance of doing business. In addition, with only one cabling system to administer, the response timeto end-user cabling requests is reduced. All of this makes one thing clear, how the “building is built” today will ultimatelydetermine how much it costs to live there tomorrow.
