The Value of Open Systems

9

Market Drivers

Owners are dissatisfied with the costs of proprietary systems– Sole-source maintenance contracts– Other operational expenses associated with energy consumption

and moves/adds/changes dictate a need to introduce more efficient and cost-effective systems

10

Market Drivers

Economic climate dictates focus on productivity– Efficiency demands better value, faster innovation, smarter

investment Homeland Security post 9/11 demands Vigilance

– Want to know “everything” going on inside “every” building– Insecurity drives desire for integrated Enterprise systems

Rapidly changing technology enables disruptive changes in the building automation landscape– The Internet, Web services, ubiquitous communication

technologies create expectation of real time information – “everywhere”, “all the time”

Demand for Open Systems– Some Specs are now requiring it– Market and Competition is growing

11

Industry Response

Focus placed on developing standards that define open systems – The leading standards are associated with BACnet and

LONWORKS Systems

12

Industry Response

All major players deliver products or systems that conform to one or more established open system standard – Many continue to invest and update proprietary product lines

Traditional players provide integrated systems (open and proprietary) and web-based access

Significant advances made in security equipment and integrated systems

Tech-savvy non-traditional players are entering the market

13

Open Systems Promise

Owners are attracted to the “Promise” of Open Systems

– Better Value for the Entire Building Life Cycle– More and better choices– Faster Innovation

15


Open building systems are created using the products and systems from multiple vendors that, as a system, offer greater flexibility, easier management, higher levels of scalability, and lower life cycle costs

LONWORKS BACnet

23

System Architecture

Description– LONWORKS provides for a flat architecture– BACnet provides a tiered architecture– LONWORKS flat peer-to-peer networks enable data exchange

directly between devices without the need for gateways or custom software

– BACnet tiered networks are designed around gateways or custom software to link sub-systems and components/subsystems from different vendors

Impact on Openness– Linking sub-systems creates “islands of automation”– Flat architectures require more training, but have lower long-term

costs– Integration of different subsystems requires more engineering– Upgrades cost more due to need for gateways and/or custom

software

System and Device Characteristics

Description– LONWORKS (LONMARK Association) enables different manufacturers

to produce products that have identical functional characteristics (both data interface and actions taken on shared data)

– BACnet allows manufacturers choose unique implementation of specific functions

Impact on Openness– Specifiers, integrators and owners must understand that there are

degrees to openness Low Range: Can’t substitute devices from other vendors – Vendor Lock High Range: Substitute and extend with any vendor’s products

– Addition of new equipment requires involvement from original integrator and manufacturer to understand how specific low level functions were actually implemented in each controller

29

Conformance Testing and Certification

Description– Certified LONMARK devices are assured to provide

specified functions– Tested BACnet devices are identified to have one or more

non-specific characteristics Impact on Openness

– Design and integration of BACnet and LONWORKS devices can be expensive

– Compliance testing makes life easier for manufacturers but harder for owners

– Certification makes life harder for manufacturers but better for end-users

34

Product Selection

Description– LONMARK Association has certified 470 devices (as of

Aug. 2003) www.lonmark.org – BACnet has tested 32 devices (as of Aug. 2003)

www.btl.org

Impact on Openness– There are lots of choices but they reflect a top-down .vs.

bottom up approach– Limited competition results in higher prices; few sources for

product; few sources for design and integration – Limited product selection may mean that the type of

function/product desired is not available

35

Network Management and Diagnostic Tools

Description– LONWORKS Network Management (design, commission,

installation) and Diagnostic Tools available from manufacturers and independent vendors that leverage a standard database

– BACnet Network Management and Diagnostic Tools only available from manufacturers

Impact on Openness– Multiple “proprietary” tools required to integrate and diagnose

multi-vendor Opportunity to remain “locked in” for upgrades

– Diagnoses and troubleshooting network issues require “proprietary” tools provided by the same manufacturer that supplied the system/devices – no vendor independence

Specifying OpenUnderstand & Help Define a Customer’s Needs

Do you need a whole-building approach to systems integration?

Is it important to be able to run the system from an application, like energy management or a performance contract?

What about the future? XML? SOAP? IP?

44


Is centralized control & sequencing required?

How important is it to be able to replace a device with one from another manufacturer at a later date?

I want to master my own destiny. Can I get all the necessary documentation, configuration information, configuration tools, programs, drivers, and other software or licensing from my suppliers?

45


How many times have you been locked in?

Do you want to be able to walk away?

Do I need multiple front ends? Can I switch?
