BACnet An American Standard,but so Much More

The tremendous success of BACnet in the worldwide build-ing automation market is not simply the result of good luckor fortunate timing. It is the result of countless hours of hardwork by dedicated industry experts who have come to sharea common vision and a process that enables effective collab-oration. Formal standardization efforts have a reputation forbeing slow, bureaucratic, and dif cult for outsiders to under-stand or in uence. Because of that widely held view, it maycome as a surprise that the standardization process has beenkey to both the technical quality and the wide acceptance of BACnet in the marketplace, but it is true.

The focal point for maintaining BACnet is a standingcommittee in the American Society of Heating, Refriger-ating, and Air-Conditioning Engineers (ASHRAE) knownas Standing Standard Project Committee 135 (SSPC 135).Even though ASHRAE is an American society and developsAmerican national standards, in practice the process is inter-national in character. The meetings of SSPC 135 are open toany interested person and, if you attend one, you will ndparticipants from throughout North America, Europe, Asia,and sometimes other parts of the world as well. Most of thepeople in the room will not even be formal members of thecommittee, but that makes no difference. SSPC 135 main-tains formal International Organizational Liaisons to helpfoster and encourage this international participation.

There is a formal continuous maintenance process thatenables anyone to submit change proposals to SSPC 135through the ASHRAE website. Sometimes that happens,but it is much more common for new ideas to come throughdirect participation. People simply show up at some meet-ings, learn how the committee works, and then begin toengage with their own ideas and contributions.

The home for the international version of BACnet (ISO16484-5) is ISO Technical Committee 205, Building Envi-ronment Design. This international standard is adoptedby many countries as a national standard. Although ISOis not bound by the American process, special procedureshave been put in place to expedite international approval of changes that come from ASHRAE. Any proposed changesto BACnet are rst submitted to SSPC 135 for consideration.Why would an international committee act in this way? It isbecause there is great con dence in both the openness andfairness of the ASHRAE process.

BACnet works because of the dedication and quality of thepeople involved in maintaining the standard. It is embracedaround the world because its contributors come from all overthe world and the process creates a collegial atmosphere thatwelcomes all comers.

The term Energy Management is all over the placethese days. You can hardly open a magazine, peruse

a conference agenda or review a product announce-ment without coming across it. I suppose all this couldbe driven by the huge amount of government moneyfocused on energy projects or maybe its a response tothe growing building owner / operator focus on energycosts, sustainability and carbon footprints. Or, it could

just be that energy is the current next big thing muchlike the web was in the late nineties and biotech was afew years back. Whatever the reason, it seems more andmore people are climbing on the Energy Managementbandwagon but not everyone understands what it reallymeans. Some people seem to equate Energy Ef ciencywith Energy Management.

Putting the M in Energy Management

There are lots of formalde nitions of Manage-ment but in general Ithink we can say it includesthree elements. To makeit simple, lets call themthe three Is Informa-tion, Intelligence and In u-ence. To effectively manageanything, we need informa-tion about the current situ-ation and perhaps infor-mation about the past. Wealso need intelligence tointerpret the information,balance competing objec-tives, consider alternatecourses of action, assessthe likely outcome of eachaction and make a deci-sion. Finally, to effectivelymanage we need the abilityto directly or indirectlyin uence the situation. So,lets look at each of thesein the context of energymanagement and explorehow BACnet enables practi-cal implementation of each.

InformationEnergy management in com-mercial buildings re quiresinformation on both energyef ciency and energy effec-tiveness. At a high level the

rst one is pretty clear. We

need to know how muchenergy the building uses asconditions change and sys-tem parameters are adjust-ed. We can get this infor-mation through directmeasurement. For example,we can measure the powerconsumption of the HVACsystem in a building as theoutdoor temperature var-ies and the internal tem-perature setpoints change.Of course, gathering datafrom an HVAC control sys-tem is not suf cient. Wealso need to gather infor-mation from lighting con-trol systems, power moni-toring systems and perhapsrefrigeration systems. Andfor many buildings todaywe need to go beyond ener-gy consumption informa-tion. We also need to gath-er information from on-sitepower generation systems inbuildings where they exist.Gathering and integratinginformation from so manybuilding systems used torequire unique design skillsand prohibitively expensivecustom software. BACnethas dramatically changedthat equation. With built-

in functionality for sophis-

ticated data collection andevent management, BACnetreduces the overall designtime and lowers the life-cycle cost of building-wideinformation collection andmanagement.

The second informationcomponent, energy effec-tiveness, is a measure of how well the use of energyis balanced with otherbuilding owner / operatorobjectives including occu-pant comfort, productivi-ty and security. Unfortu-nately, energy effectivenessis not easy to measure.BACnet cannot help whereno measurement methodexists; however it is worthnoting that the continu-ous evolution of BACnetensures systems will beable to incorporate whatev-er measures are eventuallydeveloped. Whether effec-tiveness measures eventu-ally come from advancedsensors, non-traditionalbuilding subsystems, enter-prise applications or simplyuser data entry, BACnet hasthe ability to connect to thesource and integrate theinformation.

IntelligenceThe intelligence compo-nent of energy manage-ment can be provided byknowledgeable facility staff and / or computer softwarethat re ects many years of building operations expe-rience. In either case, thepoint of intelligence is toanalyze the informationavailable and decide on a

course of action that will

balance effectiveness andef ciency. Of course, effec-tive information analysisdepends on being able toaccess all the relevant data.The balance has to takeinto account the nature of

the building and the char-acteristics of its usage. Forexample, in a retail s tore theoptimum environment is amission-critical issue sincean uncomfortable shopperhas many other choices of shopping venue. In an of cebuilding there may be morelatitude on the comfortobjective in pursuit of lowerenergy usage. For caseswhere the system intelli-gence is provided by oper-ators, BACnet speci es avariety of Operator Work-stations pro les to ensurethat diverse users have theappropriate tools for theirtask. When system intel-ligence takes the form of a software application,BACnet provides a webservices interface to allowstandard mechanisms forcommunicating the requiredinformation to the applica-tion. In both cases, BACnetenables the intelligencecomponent of manage-ment to effectively inte-grate with the informationcomponent.

In uenceIn uencing the use of energy is the third compo-nent of energy managementand it relies on the abilityto command and control avariety of building systems.In uence is exercisedthrough changes in oper-

ating parameters such as

Connecting the Dots in Building Automation

temperature setpoints, fanoperating modes, light levelsand equipment schedules.This nal link in energymanagement can be accom-plished locally throughuser interfaces or remote-ly through a networkedconnection. Regardless of how it is handled, actual-ly changing the system inresponse to intelligent anal-ysis of relevant informa-tion is an essential compo-nent of energy management.And the in uence compo-nent cannot realistically beachieved without connec-tivity both within build-ing subsystems (such asHVAC, Lighting, etc.) andamong building subsystems.Making that level of inte-

gration practical is the keybene t of a BACnet solu-tion.

With the three Is inmind we can see that an

energy ef ciency project isnot the same thing as anenergy management project.Upgrading lighting, goingto higher SEER systems andrelocating thermostats maywell improve energy ef -ciency, but these activitieslack the information andintelligence aspects of trueenergy management.

Systems that collect dataon power consumption andenvironmental variablesand post them on a websiteare not really perform-ing energy management,either. Although it is possi-ble someone will look atthe website and on thebasis of what they seemake some decisions and

change the building oper-ating parameters accord-ingly, I think most peoplethink the Intelligence andIn uence parts of theenergy management equa-

tion must be a little moreautomated than that.

SummaryThe M in energy manage-ment is the hard part of thesystem. Building controlshave been around for a longtime and are not a signi cantchallenge anymore. Databas-es, web interfaces and toolsfor turning lots of data incolorful charts are all prettyeasy to manage, too. On theother hand, it takes broad,multilevel system integra-tion to collect all of the rele-vant Information, make itvisible to people and soft-ware applications for Intel-ligent analysis and enableeffective action to In uencethe energy consumption

going forward. These are theessence of the M in energymanagement and they arecritical to getting long-termbene t. Enabling systemsthat are integrated enough

to accomplish the M inenergy management is whatBACnet is all about.

Today, with BACnet, consis-tently integrating lighting

and HVAC together inside aBAS is easy. BACnet lightingcontrol is native to the BAS,residing on the same BACnetMS / TP network as theHVAC / DDC controllers.The result is uni ed lightingcontrol that delivers substan-tial infrastructure and main-tenance savings, as well asbetter energy savings.

Better energy savingsU.S. Department of Energydata indicates that light andHVAC consume over 60 %of the energy in commercialbuild ings. Both stand-aloneand uni ed lighting con-trol can achieve basic energysavings and typically paybackin less than 3 years. Unlikestand-alone, uni ed lightingcontrol can employ moreadvanced control sequences toachieve better savings, oftenaccomplished through simpleprogramming changes.

One example being employ-ed is extending the use of occupancy sensors to auto-matically control lightsand HVAC in unoccupiedclassrooms. For example;when an area goes unoccu-pied and the BAS is in occu-pied mode the lights auto-matically switch off andthe temperature is changedto its reset value. Depen-ding upon the application,addi tional energy saving

measures can be taken by

decreasing air ow or deci-ding to bring in less outsideair.

Common classroom com -plaints with occupan-cy sensors can also beaddressed by utilizing theBAS mode, occupied orunoccupied, to automatical-ly adjust occupancy sensorstime-out values. Increasingthe value when the BAS is inoccupied mode can reducefalse-off complaints, whiledecreasing the value in theunoccupied mode can lowerenergy usage.

In addition, classroomscan employ a manual-on

control strategy for lighting

and HVAC to save energybetween the occupied starttime of the BAS, and thetime when the room is actu-ally occupied. Instead of thelights switching on at 6amwhen the BAS changes tooccupied mode, activationof the override switch turnsthe lights on and initiatesa temperature change fromreset to set point. The bottom lineEnabled by BACnet, uni edlighting control providesbetter energy savings andit eliminates the complex-ities and limitations thataccompany stand-alone orgateway lighting control.

Compared to the choices

of the past uni ed lightingcontrol is a no-brainer.

Uni ed Lighting Control MadePossible by BACnet

Before BACnet and its global adoption, integrating lightingand HVAC controls within the Building Automation System(BAS) was expensive and uncertain. Because the risksand costs associated with pre-BACnet integration did notoutweigh the bene ts, most engineers and owners wereforced to settle for stand-alone systems. The results of thepast are clear; according to industry surveys less than 10 %of existing BAS include the control of lighting.

Uni ed lighting control eliminates the complexities and limitationsthat accompany stand-alone or gateway lighting control.

IntroductionAs a communication standardBACnet is exible to allow imple-menters different options and lev-els of functionality. Looking onlyto controllers BACnet introduces5 different device pro les. Fromsmart sensors or actuators (verysmall devices in functionality) upto building controllers support-ing alarming, scheduling, trend-ing and device management differ-ent devices may support differentparts and functions of the BACnetstandard.

Assuring the best possible interop-erability is the main task for theBTL-WG (BACnet Testing Lab-oratories Working Group). Thisgroup of volunteers from differ-ent international countries includ-ing Europe maintains the BTL-test plan, develops interoperabilityguidelines and helps clarify issuesfound in testing BACnet de vices.BTL-WG is a group under thehead of BACnet International.

Conformance vs. InteroperabilityInteroperability means that two ormore devices understand each oth-er on the same functional basis.Conformance means that de vicesbehave as expected according tothe s tandard / norm. To assure thebest possible interoperability alldevices must rst be conform tothe standard. Assuming two de-vices violating the standard but inthe same way would still allow in-teroperability between these two,but if a third device conformingto the standard tries to connect itmay fail.

So only both, conformance as therst step and interoperability as

the second step, assures that all de-vices understand each other.

New guidelinesfor interoperabilityTogether with the BTL-test plan 9the BTL-WG introduces an updat-ed release of the BTL Implemen-tation Guidelines. This documentcontaining recommendations onhow to implement certain BACnetfunctionality may be used by man-ufacturers as good practice ex-

BTL-WG Introduces New BTL Test Plan 9.0

amples to assure an interoperableimplementation. The documentcan be downloaded for free fromthe BTL-WG website.

The document is also intended toavoid mistakes in implementationswhich may be made in earlier de-vices. So the guidelines help new-comers to follow the right path im-plementing BACnet.

Overview aboutthe testing processFor all pre-testers it is recommend-

ed to carefully read the two docu-ments BTL Getting started andBTL testing guide. Both docu-ments are part of the test package.

Picture 1 shows a rough overviewabout the related documents andtesting process.

IUT test plan: From the totalfunctionality which can is coveredby the test plan, the pre-tester se-lects those which apply to the IUT(Implementation under test) and

lls out the so-called IUT-func-tionality checklist. If e.g. the de-vice does not support ReadProp-ertyMultiple, this cannot be partof the testing of course. So all sup-ported functionality of the IUTapplies to the test process.

ANSI / ASHRAE 135.1 (ISO16484-6): This document con-tains the test instructions to test acertain functionality. The tests aredescribed in a pseudo-language.Test instructions may be for ex-ample: MAKE The IUT sendan alarm, WRITE Object X,OutofService=TRUE, CHECKthe IUT did not restart, etc.

BTL specifed tests: In case testsfrom 135.1 are broken or need tobe more precise BTL introducesBTL speci ed tests as an interimsapproach to bridge the gap. TheBTL speci ed tests are later givento the SSPC TI-WG (Testing andInteroperability Working Groupof the Standing Standard ProjectCommittee).

IUT EPICS: To let the tester andthe test software know about the

current content of the IUT the en-tire database of the device is de-scribed in the electronic format of the PICS (protocol implementa-tion conformance statement). Thisis necessary to have reliable infor-mation about the IUT content atthe time the IUT was handed overto the lab. If certain values change,e.g. temperature sensors, wild-cards may be included in the EP-ICS. The le is in text format de-scribing the functionality in theheader section of the document(BIBBS, supported Object Types,Data-Link-Layer, etc.) plus a copyof all objects contained and a listof all properties and values.

Test scripts: While some tests caneasily be issued manually using ex-plorer tools, the VTS (Visual TestShell) or even a B-OWS (OperatorWorkstation), some tests are easi-er to repeat using scripts. VTS has

a simple but limited scripting lan-guage, the BACnet Test Frame-work software is not as exible asVTS for spot checks but with itsPYTHON integration (a popularscripting language) it is perfect forrepetitive tests.

Test toolsAs said above, there are many op-tions for different tools to testBACnet functionality and pre-tes-ters should not only rely on one sin-gle tool. In addition to the tools apre-tester should also use a net-work sniffer like Wireshark to an-alyze the packets on the networkand for testing MS / TP timing a se-rial analyzer and an oscilloscope isrequired.

Functional areasin the BTL test plan 5.0The old test plan 5.0 has beenin use for almost 2 years now andneeded to be updated. The testplan number by the way representsthe supported BACnet-revision, sotest plan 5 covered BACnet func-

tionality of up to BACnet revision

5, this explains why BTL jumpsfrom 5 to 9 now.

The test plan covers different areasof functionality to be tested.

Basic Functionality: This must besupported by all BACnet devices.

Objects: According to the sup-ported object types of the IUT cer-tain tests must be applied to testthe correct object behavior. If spe-cial functionality is supported likeelapsed active time counting orwritable state text properties, etc.certain extra tests apply.

Data-Sharing BIBBs: With thesetests the data-exchange (reading,writing, COV-reporting, etc.) istested.

Alarm and Event Management BIBBs: With these tests alarmingis tested. This includes transport of alarms, event-information, enroll-ment-information and alarm ac-knowledgement.

Scheduling BIBBs: With these testsexecuting and exchanging scheduleprograms is tested. This includesviewing and modifying scheduleprograms as well as testing the cor-rectness to schedule on time in-cluding exception schedule.

Trending BIBBs: These tests areintended to test the correctness of trending capabilities and to testcorrect responses using the Read-Range service to retrieve trend logdata. It also includes testing thecorrect behavior purging the bufferand star ting / stopping the logging.

Device and Network Manage-ment BIBBs: These tests are usedto check the correct behavior of device management functions likedevice- and object binding (Who-Is, I-Am, Who-Has, I-Have), re-start, device communication, time-synchronization, etc. up to backupand restore.

Data Link Layer: Depending onthe supported layer certain tests

apply to the IUT. BACnet / IP forexample requires non-BBMD andif applicable BBMD tests, MS / TPmaster devices require to passthe poll-for-master tests and to-ken-passing tests just to mentiona few.

Routing: If the IUT is a router orcan be made to provide routing ca-pabilities, routing between the dif-ferent layers is tested as well.

BACnet insight

Bernhard Isler 1

The most recent ASHRAESSPC-135 BACnet Committeemeeting took place in Montreal,Canada, at the ASHRAE AnnualMeeting over the last week-end of

June. Substantial work was per-formed during these meetings,both by the subordinate work-ing groups and in the plenary ses-sions. Clear focus was put on pro-cessing public review commentsand preparing addenda drafts fornext public review. Also, a num-ber of new addenda were com-piled and approved by the com-mittee for initial public review.

In May, a one week interim meet-ing was held in San Francisco. Asa premiere for the spring interimmeeting, after many years assem-bling in Germantown MD, the Pa-ci c Energy Center, a PG&E ven-ue, provided excellent meetingfacilities for the working groupsand the plenary. These meetingrooms usually serve for trainingson HVAC and other building in-frastructure, thus created an in-spiring environment for the at-

tendees.Although some addenda were stillopen for public review while theSan Francisco meeting, commentresolution and addenda draft re-vision was performed as far ascomments were available. All thiswork was considered being prep-aration for the regular committeemeeting to take place in Montreal.

BACnet 2010 publishedThis spring, a new compilationof the BACnet standard was pub-lished by ASHRAE. The bluebook is now more than 1000 pag-

es. For the paper print, thinnerpaper was chosen to keep the sizeof the book limited. BACnet 2010incorporates BACnet 2008 andall addenda approved and pub-lished by end of January 2011.This includes addenda g, h, j, k,

While the Montreal meeting, theASHRAE board of directors ap-proved the rst three addendato BACnet 2010 for publication.Those were:

Addendum

135-2010ad Miscellaneous changes

Addendum135-2010ae Minor physical access control changes

Addendum135-2010af Alarming revision

Alarming revision approvedfor publicationAmong the addenda approvedfor publication is addendum 135-2010 af . This completes exten-sive work of the objects & ser-vices working group (OS-WG)and the committee on the com-prehensive overhaul of the alarmand event detection and report-ing mechanism. Backward com-

patibility was a major concernin this endeavor. The conceptsare now clearly described at oneplace. Inconsistencies are re-moved, as well as aws and un-necessary restrictions. Con g-uration for event detection anddynamic inhibition is added asa general principle to all eventreporting objects. New mecha-nisms for stateless alert noti ca-tions and event noti cation for-warding are added.

But work on alarming is not yetnished. The OS -WG has a num-

ber of proposals on the plate t hat

build on addendum 135-2010 af ,and will provide new event algo-rithms, add extended capabili-ties to existing algorithms, andwill relax requirements on sup-port of some outdated alarmsummarization services.

Addenda approvedfor public reviewIn Montreal, a number of ad-denda were approved for ini-tial or subsequent public review.Those are addenda to 135-2010as well as to the test standard135.1-2009. All addenda to stan-dard 135-2008 that were not ap-proved for publication when135-2010 was compiled and pub-lished are now addenda to 135-2010, keeping the respective ad-dendum identi cation letters thesame. Addendum 135-2008 i isnow Addendum 135-2010 i, as anexample. The addenda approvedfor regular publication publicreview (PPR) are:

Addendum135-2010i PPR5 Lighting Output Object

Addendum135.1-2009l PPR2 Miscellaneous Changes

Addendum135.1-2009m PPR2 Test Additions

Addendum135.1-2009n PPR2 Miscellaneous Tests

For the rst time, the commit-tee approved two addenda to 15-2010 for public review using thenew advisory public review(APR) process. This process hasbeen introduced by ASHRAE re-cently allowing committees tocollect advisory comments fromthe public. As it is with the well

known publication public re-view, comments are submittedthrough the regular online com-ment database web interface.APR comments received are notrequired to be of cially resolved.They serve as guidance to the

committee on proceeding. Theultimate public review beforepublication has to be a publica-tion public review still. The ad-denda approved for APR were:

Addendum135-2010am APR1

New BACnet / WS WebServices

Addendum135-2010an APR1 MS / TP Extended Frames

New BACnet / WS web servicesAddendum 135-2010 am intro-duces a set of new BACnet / WSweb services. This extends An-nex N with web services thatfollow the HTTP REST mod-el. They use the Atom Publish-ing Protocol (RFC 5023) andexchange data using the AtomSyndication Format (RFC 4287).For pushing feed data to clients,publish / subscribe services a re in-troduced that use the PubSub-Hubbub procedure. For struc-tured data, the BACnet / XMLformat de nitions of 135-2010Annex Q are used.

MS / TP extended framesAddendum 135-2010 an proposesextensions to the MS / TP datalinkde nition to enable the transportof large frames. With this, MS / TPbecomes able to transport framesthat are of the same size as trans-portable on other BACnet dat-alinks, such as BACnet / IP.

A major obstacle found in elabo-rating this addendum was that theCRC-16 used for the today small-er frames is known to provide in-suf cient error detection whenusing it for large frames. To over-come this and keep the error de-

tection capabilities on an accept-able level, the large frames willuse a CRC-32, with a carefully se-lected Koopman polynomial.

Banner Year for New BTL Listed Products

This has been a banner year for new BTL Listed products. Already in 2011 moreproducts have obtained the BTL Listing than in any year previously, and thats withhalf the year yet to come! This year through testing, the following vendors deviceshave earned the right to display the BTL Mark.

The BTL Listing is a testimo-nial that the product was sub-jected to rigorous veri cationby testing, demonstratingthat it correctly implementsinteroperable BACnet. Thatrequirement is steadily beco-ming the benchmark statedin project speci cations, toavoid sub-standard imple-mentations.

Passing BTL testThe BTL Mark is permittedto be displayed on deviceswhich have passed BTL Test-ing. This testing ensures thata device correctly implementsall of the BACnet function-ality that it contains. ASH-RAE standard 135.1 2009and the BTL Test Plan gover-ns the testing.

There are three documentsrequired to be lled out andmailed/emailed to in order to make applicationfor testing and commence thetesting process. Fillable formsand instructions describingthe entire testing process arein the 5.0 test package, atwww.bacnetinternational.org/

associations/8066/files/BTL_Test_Package_5.0. nal.zip

The BTL Checklist and BTLTesting Application deter-mine the testing which willbe performed. Every deviceis different, but a scheduleestimate and testcase can becreated from those two do-cuments. A signed BTL Te-sting Agrmt and US$1,000

deposit secures a place inthe test queue. BACnet In-ternational member compa-nies at Silver level or higherreceive a discount on testingfees.

It is common for testing anda Listing to apply to a fami-ly of devices that share un-derlying BACnet software.

We test only the BACnetfunction ality. If the samermware is used in common

amongst devices, one testingand one Listing can apply tothe family.

If you have any further ques-tions please do not hesitateto ask. I look forward to see-ing your application for BTLtesting.

Why go BTL?

There are a number of manufacturers who makevarious products designed tocommunicate within a build-

ing. Everything from eleva-tors to HVAC to lighting toaccess control are being inte-grated to give a more detailedpicture and more precisecontrol over the systems oper-ating within facilities global-ly. With complete integra-tion, buildings can be drawntogether to communicateover the Internet and giveusers access to their systemfrom almost anywhere inthe world. While all of thisto some might appear to beGreek and black magic allwrapped into one, much of it is made possible throughthe use of open protocols.More speci cally, it is beingmade easier through the useof BACnet.

The importance of BACnetTo understand why goBTL, one must rst realizethe importance of BACnet.In the not so distant past,systems were designed bydifferent manufacturersto only communicate withproducts they created. Thismeant if you wanted dispa-rate systems to talk to oneanother you would needsomeone to write specialdrivers to get them communi-cating. Some manufacturersmade their protocols avail-able publicly and others hidthem to prevent the prolifer-ation of competitor product

on sites with their systems.Today, this philosophy of doing business still exists.However, with the advent

of BACnet, users have morechoices. They can chooseBACnet products! Whethera building is being retro ttedto communicate with oldersystems or being integrat-ed for the rst time, thereare a number of productsthat exist today that allowmore streamlined integrationthrough BACnet. If you arenew to this, and are thinkinghuh? Think of BACnet asa human language.

BACnet languageEach person performingneeds to tell the next person acommand or report on some-thing they have been doing.If everyone were from adifferent country and did notspeak a common language,you would need translators.But if everybody is speak-ing BACnet, then they allunderstand each other andcan perform more ef cient-ly with less communica-tion breakdown or points of failure through the transla-tors. In the building world,this means less gateways andless reliance on drivers beingwritten correctly by integra-tion houses or manufactur-ers to convert protocols. Of course one thing we have notdiscussed yet is what if every-one is not speaking the samedialect? How do we know aBACnet product is designed

The BTL mark. We have seen it. Maybe it was in a spec-i cation, or a product we installed. Was it possibly on awebsite or advertisement created by those wonderfullywacky BACnet International people; a mystical circular logoglowing as if the sun was rising for the rst time? Or wasit a tattoo on that guy at the trade show? Ok. Maybe noone has a BTL tattoo, but a lot of BACnet products do, andmore and more are being listed every day. BTL is an impor-tant part of being BACnet.

to communicate with the

next BACnet product andnot a different interpretationof the protocol? Enter BTL.

What BTL isBTL stands for BACnetTesting Laboratory. This isan independent organizationcreated by BACnet Interna-tional to perform testing onBACnet products to ensurethey meet the standards setforth in their listing. Thisbene ts the manufactur-er and consumer in multipleways. Firstly, it guaranteesthe product has been testedfor correct BACnet imple-mentation. Rather than havethe product released by amanufacturer, installed, andthen nd protocol mistakesthat may have been made,BTL catches these implemen-tation errors and informs themanufacturer and requiresthey be corrected. This savestime and money on the partof both the manufacturerand the customer. In fact,to date no product submit-ted to BTL has come to betested and been error free.Secondly, having the BTLmark on a product meansit has been tested rigorous-ly to a standard. If it has themark, the end-user, engineer-ing rm, and installer can allrest assured it will commu-nicate with other producttested to the same stan-

dard. Finally, in the speci-

cation marketplace it hasbecome dif cult to get intoa building speci cationwithout the BTL mark. So,for the manufacturer it canbe a show-stopper withoutthe mark or at the least makeit much more dif cult to geton the project. With over 60manufacturers today meetingBTL standards, not havingthe listing means being moresusceptible to being left out.With BTL the manufactureris letting the consumer knowtheir product will communi-cate according to the stan-dard while ensuring theirown compliance and makingit easier to be speci ed.

Testing speci cfunctionalityAs with all testing standardsit is important to rememberBTL is testing speci c func-tionality. Look for othermarks to ensure compliancyto safety and federal commu-nication standards. In addi-tion, remember having theBTL mark does not mean theproduct is now a commod-ity and one product is justas good as another. TheBACnet standard is designedfor protocol communica-tions con rmation while stillleaving competitive exibilityfor manufacturers to designproducts with speci c func-tionality and capabilities

not found with a compet-itive brand. Also, manufac-turers should not make themistake of thinking theirproduct is now bulletproof once it passes BTL. Appro-priate testing for other func-tions and capabilities shouldbe applied. End-users, install-ers, and engineers shouldresearch each product forfunctionality and othercompliancies before makinga decision.

BACnet conformanceHaving BTL on a productmeans the manufacturer iswilling to invest in ensuringconformance to the BACnetstandard. While there prob-ably is no human out theresporting the BTL trademark

as skin art, there are a largenumber of manufacturers thatare proud to display BTL onwhat they sell. Whether youare looking at getting yourproduct listed, looking for theimportance of it in the spec-i cation, or thinking aboutadding a BACnet product toyour facility, look for the BTLmark. It will ensure everythingis communicating accordingto the standard.

With luck you were near or on the perimeter of the booth.

Design improvements spanned multiple years.

Hot Spot in Vegas BACnet International Booth

As a non-pro t, largely volun-teer organization, it is some-times dif cult to organizeand resolve issues that youcould quickly address in a for-pro t company. I would liketo share with you how theBACnet International AHRExpo booth evolved intothe eye-grabbing hot spot itwas in 2011. The 2011 AHRExpo show booth represent-ed the culmination of designimprovements that spannedmultiple years to conceive,approve, fund and implement.

Evolution of the solutionFirst, we eliminated the badspots. In AHR Expos of the

past there were interior andexterior booth manning posi-tions. If you were a luckymember participant, you wereon or near the perimeter of the booth and spoke to a lotof people during the show.If you were on the interior,well, you had plenty of timeto organize your thoughts.Another problem in the boothdesign was that kiosks withinthe booth were divided infour sections and shared.Even though united in ourefforts to promote the BACnetmessage, members under-standably prefer not to standdirectly next to their largestindustry competitors. Recog-

If youve ever manned a tradeshow booth, youre likelyfamiliar with the sense of urgency to bring back a stackof business cards and quali ed leads to justify the trip.This is one of the reasons why I nd it so refreshing todesign and work in the BACnet International boothat AHR Expo. As an organization whose purpose is toactively promote improving building controls by encour-aging the adoption of the BACnet protocol, BACnetInternational is at AHR Expo in a more educationalcapacity. It is also very interesting to stand, side-by-sidewith industry peers whose companies are the whoswho of building automation, united in the common

purpose of improving building controls by inuencing thedirection of global control speci cations.

nizing these issues, BACnetInternational adopted adesign change in 2010 thatgave every booth participanttheir own company brandedkiosk on the perimeter of thebooth. Position inequality wassolved. To provide membercompanies the opportunity tomeet with trade show attend-ees and customers we addeda meeting table to the middleof the booth and viol, thebooth became a signi cantlymore inviting.

Though BACnet Interna-tional consists of morethan 75 member compa-nies, you would not be ableto tell from the 2009 boothdesign. Attendees were oftenconfused when they visitedthe booth. Frequently, visi-tors thought that we were anorganization that sold prod-ucts, not one promoting theBACnet protocol. To helpaddress this issue the deci-sion was made to put the logoof every member company of BACnet International on theexterior walls of the booth.This provided members, eventhose not directly participat-ing in AHR Expo, an addi-tional bene t of member-ship while giving trade show

attendees a better idea of

who BACnet Internationalis. We still get the occasionalconfused visitor; but requestsfor our line cards have dimin-ished signi cantly.

With these changes cameanother inequality to address.As one would expect, largecompanies can afford to senda lot of hardware and one of their employees to man a kioskposition in the BACnet Inter-national booth; however, theMarketing Committee recog-nized that these costs causedsmaller and newer membersto be underrepresented at theshow. No solution on how toinclude them without dimin-ishing the investments of thelarger companies and valueof their premium positionswas readily evident. It wasntuntil the Marketing Commit-tee was addressing a differ-ent issue, maximizing boothtraf c, that the solution to theproblem presented itself; llthe interior of the booth withBACnet technology.

On the surface, this soundedlike a simple idea that wouldbe easily implemented;however, mounting hardwarein the booth of AHR Exposin past was always problem-

atic, at best. Rarely did

There is no better wayto learn what you havemistakenly assumed every-one does the same, than ata BACnet PlugFest. Betterat PlugFest, with engineersand tools at hand, than viairate calls from the eld,says BTL Manager DuffyOCraven. Attendees are averitable whos who of individuals and companieswho work in the BACnetcommunity.

This three day event featurestwelve testing sessions,during which teamsassigned to test with eachother test freely in pairs orat roundtables designed formulti-vendor testing, calledround table testing.

The one-on-one testingsessions allow each team totest their products with indi-vidual company products inscheduled sessions. Therewill be several sessions, onehour or two hours in length,

during the workshop. Pair-

ings are assigned by the BTLbased on vendor availabil-ity and vendor preferenc-es. The round tables avail-able on Day 2 and Day 3of the Workshop are avail-able to teams who wish tohave ad hoc testing with theother vendors who chooseto participate in the roundtable that session.

In addition, the 2011 eventwill feature workshops taughtby leaders in the eld:

Thisis the twelfth annual BACnet Interoperability Workshopand is hosted by BACnet International. PlugFest permitsvendors to test their BACnet products in a neutral andfriendly environment with BACnet devices from othervendors. Last year 98 BACnet engineers representing35 companies attended the workshop and improved theirBACnet implementations and testing methods.

we ll the walls with

BACnet technology. Moreoften the walls were sparse-ly populated with hard-ware and the gaps were lledwith literature racks. Therewere many, understandablereasons for this:1. We have no idea of

knowing how much hard-ware to bring and willthere be enough space tomount it.

2. Were sending a sales guy,not a hardware guy toman the booth, so hellmount whatever he has inhis bag.

3. We have to comply withcrazy union rules formounting? I just ewin. I dont have time forthat. Just forget it!

The elegant resolutionWhat if we gave members theopportunity to produce, attheir leisure, in their place of work, an organized BACnettechnology display that theyjust shipped to the show andwas hanging up in the boothwhen they arrived? At AHRExpo 2011, BACnet Inter-national introduced themember technology show-cases. Accessible to bothlarge and small compa-nies, fourteen participatingmembers receive a 7.5 squarefoot panel to pre-mount andwire their BACnet offerings.The resulting display on theinterior of the BACnet Inter-

national booth resulted in

a tremendous amount of

traf c at the 2011 show.The BACnet Internation-al booth at AHR Expo 2011was hailed as a crowd andmember pleaser. Over thethree-day course of the showthere was rarely anything butstanding room only in thebooth. Im pleased to reportthat the 2011 booth helpdemonstrate the global natureof BACnet, the wide varietyof participating companiesand the breadth of avail-able technology solutions forbuilding automation. ThoughId love to tell you what wereworking on for AHR Expo2012, youll just have to visitus in Chicago to see for your-self.

A Tribute to Bill SwanBy Steven T. Bushby, H. Michael Newman and Kathy Swan

Bill was born in Virginia in the early spring of 1952 and wassoon the oldest of the three children, himself and two sisters,in his family. Their parents, the Rev. William Orr Swan, Jr.,and his wife Mary, took them to Michigan where his fathersday job was with Dow Chemical in Midland. Bills penchantfor things technical showed itself early on. He was proud of having put together a Star Roamer radio kit all by himself,thus being able to listen to religious music on Sunday nights.And he also learned to play the baritone horn and tuba inthe Midland High School band and orchestra, skills thatprepared him in later life to tackle the recorder and bagpipes.

EducationWhen Bill was sixteen, half way through his high schoolcareer, his family moved to Sunnyvale, California, wherehe graduated from Homestead High School, alongside thefuture founders of Apple, Steve Jobs and Steve Wozniak.While they were preparing, one must suppose, to becomemulti-millionaires, Bill was having fun in the electronicslab and playing around with CB and ham radio. Bill thenwent on to study at Foothill College in Los Altos Hills andmanaged to land an internship at the NASA Ames ResearchCenter in Mountain View where he had the chance to workon wind tunnel tests of the Space Shuttle before the rst oneever ew.

Bill earned his Bachelors Degree then continued in graduateschool at the University of California at Santa Barbaraand, in 1978, he earned his Masters Degree in ElectricalEngineering and Computer Science, Magna Cum Laude. Billsengineering career had already begun with his rst job at E2Tin Carpinteria, California.After graduation, he wentto work for Paratronics inSan Jose, Alspa Computerin Santa Cruz, AppliedMicrosystems in Redmond,Washington, PersonalScienti c in Woodinville(later to become Summationin Kirkland) and CSI in Lynnwood. Many of these were thekind of small startups that Bill loved best of all. Even Alertonin Redmond, Washington, Bills rst building automationcompany, was a startup that, at the time, was little knownoutside the Paci c Northwest. When Bill started there in1995, he was immediately put to work writing code forAlertons controllers.

CareerBills BACnet career began the same year, even before thestandard was nally published. His superiors at Alerton,

having discussed the possible future of the protocol withthe chair of the ASHRAE BACnet committee, decidedthat adopting BACnet would be a winning proposition: if it succeeded in the marketplace, Alerton would be one of the rst companies with interoperable BACnet products; if itfailed, Alerton would still have a modern, capable protocol,developed by industry experts, for use in its own productsthat cost the company nothing to develop.

Bill remembered it this way in recollections that he sent toMike Newman years later:

Sometime around Marchof 1995 Tony [Fassbind,Alertons CEO] handed mea book, BACnet PR2 [publicreview draft 2], and asked me to read it. Which I did.Once. It didnt make muchsense (it was very broad

unlike other standards Id read, such as IEEE 488) and Tony never asked me anything about it, so I forgot it.

Months later Tony and Clair [Jenkins, Alertons President]called a company meeting for Thursday, August 17, 1995at 10 AM, in the company lunchroom. Tony reviewed Alertons history and how we got into the industry bylatching onto a new idea, direct digital controls, that thebig players with their investment in pneumatic controlswere avoiding. He noted (sur ng analogy drawn on awhiteboard) that this wave rolled through the industry and

Thats when the un began. But within a ew months I was felding questions such as How do I encodean ObjectIdentifer? and way too o ten responding,Thats Clause 20.2.14, page 342, and ipping it open, and thats where it was! This worried mycoworkers a bit. (I cannot do that anymore.)


25/28



enabled a number of startups to get into the market.He noted also that its unusual to have two such wavesroll through an industry in one lifetime but he and Clair saw a second one coming. Our customers wanted the independence BACnet would give them, but nomanufacturers were giving BACnet anything morethan lip service. He and Clair s aw a huge opportunityto become an industry leader and they were going to bet the company on it by rolling out a completeBACnet line of products, similar to our Ibex line, topto bottom BACnet from the workstation down to the

unitary controllers. He warned it wouldnt be easy: wewere going to have to give our customers the utmost inservice or ri sk losing them.

In conclusion he held up a copy of the standard (it must have been the 1994 PR2 draft because I dont think the1995 version was in print yet) saying, This is now ourbible. Then he hands it to me and says, And yourenow the expert. Learn it.

So by September 1995 we were already on course,though not too far down the road.

BACnet roleNot only did Alerton tag Bill to lead their internalBACnet development efforts, they sent him off to jointhe BACnet committee and Bill showed up for his rstmeeting in June 1996 across from the Alamo in SanAntonio. His talent and enthusiasm were recognizedby his colleagues and he soon began to work his wayup through the chairs, becoming a working groupleader, then committee Secretary, Vice-Chairman and,

nally in 2004, Chairman. Throughout this time, Billspearheaded many technical initiatives, such as workon re nements to BACnets Master-Slave / Token-Passing protocol, its character set processing, andissues surrounding Network Address Translation,among others. All told, Bill authored about 93 changeproposals, a staggering record. Even after passing theChairs baton in 2008, Bill continued to participate andmost recently was leading the effort to develop BACnetextensions for elevator systems.

But while Bill will be remembered by many for histechnical accomplishments and contributions, notjust to BACnet but to the even broader eld of energyconservation, many of us will recall how he blossomedas an individual. Somewhat shy and a bit uncertainabout his ability to lead the BACnet committee, Billquickly learned the ASHRAE processes and procedures.

More importantly, he gained con dence in dealing withASHRAEs staff and of cers and became an effectivespokesperson for BACnet, even lifting the occasionalscotch at the Societys Presidential Cocktail Parties. WhenHoneywell took over Alerton, Bill was sent to representthe company and BACnet at the BACnet Interest Group Europe and became its rst non-European vice-president.He also traveled the globe to attend meetings of ISOsTC 205, the committee that promoted BACnet to aninternational standard.

When the opportunity arose, Bill added to his portfolioby accepting the challenge of becoming the ASHRAErepresentative to the NIST Smart Grid InteroperabilityPanel. In that role he became immersed in the huge nationaleffort to create a standards framework that will enablea completely transformed electric grid. Bill was thrilledto be intimately involved in a new industry-transformingactivity.

Mike and Steve came to know Bill through his professionalactivities, but after years of meetings, dinners, and worldtravel they also came to know him on a very personallevel. Bill was deeply religious, a devoted husband, a lovingfather and a good friend.

Bills untimely death has left an ache in the hear ts of all of us who knew him. He will be sorely missed!
