The Value of Open Systems © 2003 Echelon

Market Drivers l 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 9

Market Drivers 10 l Economic climate dictates focus on productivity – Efficiency demands better value, faster innovation, smarter investment l Homeland Security post 9/11 demands Vigilance – Want to know “everything” going on inside “every” building – Insecurity drives desire for integrated Enterprise systems l 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” l Demand for Open Systems

Industry Response l Focus placed on developing standards that define open systems – The leading standards are associated with BACnet and LONWORKS Systems 11

Industry Response l 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 12 l Traditional players provide integrated systems (open and proprietary) and webbased access l Significant advances made in security equipment and integrated systems l Tech-savvy non-traditional players are entering the market

Open Systems Promise l Owners are attracted to the “Promise” of Open Systems – Better Value for the Entire Building Life Cycle – More and better choices – Faster Innovation 13

Open Systems Defined l 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 15

Open Systems A Control Systems Evolution Master/slave Stand-alone controllers Networks Closed, single-vendor Open, multi- Centralized Home-run Wired 16 Distributed systems Tiered Islands of Proprietary Sub-systems Flat, open, multi-vender

Open Systems Create Opportunity by … 19 l Providing a standard system architecture l Allowing a comprehensive solution from Device to Enterprise Integration l Creating a common tool platform across multiple manufacturers products l Simplifying Adds/Moves/Changes as well as Monitoring, Control and Visualization l Open Systems are – The basis for Innovation, Differentiation, and Competition – An opportunity for specifiers, integrators and end-users

LONWORKS & BACnet A Comparison © 2003 Echelon

Comparing BACnet and LONWORKS Key areas to examine 21 l System Architecture l System and Device Characteristics l Conformance Testing and Certification l Product Selection l Network Management l Diagnostic Tools l Market Presence

Historical Comparison LONWORKS l 1988 – Released by the Echelon Corporation l l 1994 – Lon. Mark® Organization formed l 1995 – 1 st certified product l 1997 – LNS 1. 0 released l 1998 – 100 th certified product l 1999 – ANSI/EIA standard l l 1987 – ASHRAE committee formed 1995 – BACnet 1995 Released l 2001 – BACnet 2001 Released l 1999 – 200 th certified product 2002 – BTL begins product testing l 2001 – 300 th certified product l 2002 – 1 st tested product l 2002 – Address space increased through ANSI l 2002 - XML Work Group established l 2002 – 400 th device certified l 2003 – Becomes ISO Standard 16484 -5 l 22 BACnet 500 th 2003 – device certified (estimated)

System Architecture 23 l Description l Impact on Openness – 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 – 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 l 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 l Impact on Openness – Specifiers, integrators and owners must understand that there are degrees to openness l l 27 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

Conformance Testing and Certification 29 l Description – Certified LONMARK devices are assured to provide specified functions – Tested BACnet devices are identified to have one or more non-specific characteristics l 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

Product Selection 34 l 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 l Impact on Openness – There are lots of choices but they reflect a topdown. 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

Network Management and Diagnostic Tools l 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 l Impact on Openness – Multiple “proprietary” tools required to integrate and diagnose multi-vendor l 35 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 Open Understand & Help Define a Customer’s Needs © 2003 Echelon

Specifying Open Understand & Help Define a Customer’s Needs 43 l Do you need a whole-building approach to systems integration? l Is it important to be able to run the system from an application, like energy management or a performance contract? l What about the future? XML? SOAP? IP?

Specifying Open Understand & Help Define a Customer’s Needs 44 l Is centralized control & sequencing required? l How important is it to be able to replace a device with one from another manufacturer at a later date? l 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?

Specifying Open Understand & Help Define a Customer’s Needs 45 l How many times have you been locked in? l Do you want to be able to walk away? l Do I need multiple front ends? Can I switch?
