From the family
The family of Bill Swan regrets to inform that he passed away Saturday June 4th at John Muir Medical Center in Concord, CA. His illness was unexpected, but his passing was peaceful and in the presence of his family. He is survived by his parents, his wife Kathleen and two daughters.
*Update*
A memorial service is scheduled for all who would like to attend, Wednesday, July 6th at 11 a.m. at St Bartholomew's Anglican Church located at 14821 Avondale Road NE, Woodinville, WA 98072.
From the bottom of our hearts, thank you all for your kind words and well wishes.

An Internet Address for Every Light Bulb
Watching the development of BACnet's lighting control extensions, it's clear to me that while one can easily do "On -- Off -- %FullOutput", there is a whole lot more to lighting control than can be conveyed via a simple Android app. And that's even before you try to go beyond individual control of each lamp -- think about lighting up the house on the way home from the airport, or at least the path from the garage to the bedroom (so I don't have to to flip switches with both hands full of luggage). There aren't enough stoplights between SeaTac airport (SEA) and home for me to turn on the requisite set of lamps remotely, one by one, enroute.
What these folks are doing is something to watch, certainly, but it doesn't seem to me to be the full answer.
And I hope their power control devices are more robust today than the X10 devices sold in the early 1970s; the vulnerability of the old X10 semiconductors (SCRs/Triacs) to filament-lamp-short failures is the main reason I've never installed X10 in any of my residences.
Plug(fest) 'n Play
But now it's over and I'm back in the office (for a couple of days) with reports to write. It's not close to a major airport but I would not be unhappy, though, if we returned to Saarbrücken for the next plugfest -- or a BIG-EU meeting.

Romantische BACnet
I will admit up front that, like most Americans, I had never heard of the city of Saarbrücken in northwestern Germany. The travel guides I read barely even mention it; all I heard was "a city in the industrial Ruhr valley," so I didn't expect much. And difficulty in sleeping upon my arrival (leaving this Seattleite "Sleepless in Saarbrücken" -- but it's my fault) didn't improve expectations.
Was I ever wrong.
I had little time to tour, and from this point on it's (almost) all business, but I truly enjoyed my short walking tour around the old town yesterday, with at least a few photos of Saarbrücken with which to remember it. I hope sometime I will be able to return, better prepared.
But that's over and now we're deep into the plugfest testing at the Handwerkskammer des Saarlandes (Saarland Chamber of Crafts -- a great facility, by the way: spacious and comfortable). It's a serious event so, because many of us are competitors, we have to lighten things up a little.
One new jest centers on the general conduct of the event: the testing teams are paired up, two by two, and for a couple of hours test their products together. The tests start with a simple "Can my device see yours on the network?" and (usually) quickly progresses to more testing sophisticated interoperations involving setting up time schedules; trendlogging data; configuring, issuing and acknowedging alarms; and more. But this pairing is now called "speed-dating."
Frank Schubert noted last evening, following the day's "speed-dating" our intrepid band of BACneteers had settled down to a romantic ("romantische") candlelight dinner at a nearby Italian restaurant.
But now it's early morning, we have another day of "speed-dating" ahead of us, and I must go prepare. "Tschüss" (bye).

Casting our nets wider
A bigger surprise came in yesterday's MS/TP LAN working group meeting, on a discussion on expanding the maximum frame size for this low-cost LAN from 501 bytes to 4096 bytes. This technology has been around for some time and well understood - we thought. But IEEE's Kerry Lynn surprised me (at least) when he revealed that increasing the frame size 8-fold would increase the error rate a thousand-fold!
He referenced studies on CRC algorithms from Dr. Philip Koopman (online here), noting that there's a frequent assumption that "other have done their homework" in areas such as this, when in fact they might not have. Characteristics of the CRC-CCITT and other polynomials have been investigated; the following plot shows one result. Kerry will be providing guidance in this area.
"Energy Conservation in Existing Buildings" in public review
The questions cover a broad range of issues including lighting upgrades and payback periods, commissioning (much potential here, thinking possibly of the International Green Construction Code, which provides an extensive set of specifics related to commissioning), and weather (question below), which is a current topic of discussion in our "buildings" corner of the federally-directed Smart Grid development.

BACnet preparations
The "companion" (or derivative) proposal, WS-093, "Elevator Structures in BACnet," should give the Application Profiles group something to think about. Their work for so very long has been on how (and what) to model for standard building automation devices such as variable-frequency drives and VAV controllers, but this proposal presents something different: How to group a number of objects (Lifts, Escalators, Elevator Groups and so on) into some kind of a traversable hierarchical system that could span across devices or larger entities.
(Think "City of Hong Kong" -- "Building 123 Main St" -- "Tower 5" -- "Elevator Group 3" -- Lift 2" and you might get an idea.)
It could be a fun time in the meetings week after next.
And then I'm off to Saarbrücken, Germany, for the European plugfest the week after.
Almost ready for that too: today I registered the Alerton devices I'm bringing with the Customs and Border Protection folks, down at the King County International Airport in Seattle. (Until this week I didn't even know we had a "King County Airport," much less an international one!) The officials didn't seem impressed by all the advanced BACnet technology embedded in the little plastic boxes on DIN rails. And they didn't seem like they wanted to hear about the increased comfort and lower operational costs these little boxes could give them, or what the Smart Grid would soon do for them, or...
Oh, well.

LEED for Healthcare approved
Reportedly among its prerequisites are minimizing the use of potable water for cooling medical equipment, and "eliminating mercury" (does this include a prohibition on CFLs & fluorescents? -- I guess I will have to wait to see). For the latter, I learned a new acronym we'll no doubt see more often, and not just in new LEED systems: PBT, for "Persistent Bioaccumulative [or] Toxic" chemical. Plus there is a new prerequisite: removal or encapsulation of hazardoous materials.
Looks like I will have more new reading ahead, including the UK's BREAAM Healthcare along with the US' LEED for Healthcare. It will be interesting to see if there are elements to be included in future energy talks.

New BACnet addenda in public review (3/25 - 5/09)
Addendum 135-2008ae, 2nd PR (public review)Most of these, obviously, modify the BACnet testing standard, ASHRAE 135.1-2009, and thus are most likely to be of interest to BACnet manufacturers.
- Physical Access Control, Access Door object, new enumerations for Door_Status and Lock_Status properties
Addendum 135-2008ak, 1st PR
- Define explicitly-required ranges for Device Instances and MAC Addresses
- specify 'abort-reason' for specific situations in Clause 5 Transaction State Machines
- Add a Serial_Number property
Addendum 135.1-2008j, 1st PR
Addendum 135.1-2008l, 1st PR
Addendum 135.1-2008m, 1st PR
Addendum 135.1-2008n, 1st PR
- Improve, clarify, revise, generalize, correct, update, replace and add tests
Addendum 135.1-2008k, 1st PR
- Add new manual MS/TP tests
This is, possibly, the last opportunity for the public to review and comment on these proposed changes. If no comments are received, public acceptance is assumed and they will be published as additions to the standards. You can review and comment here.

European Plugfest is a GO
It was difficult to figure out how to arrange this, since the BACnet Committee meetings were tentatively scheduled the following week, traditionally leading off with the testing-related working groups (B.I.'s BACnet Testing Labs working group and the BACnet Committee's testing & Interoperation group). For those of us from North America this posed a problem; we could not fly home from Europe until Saturday and then we would have to turnaround and fly out (to San Francisco) on Sunday for the start of meetings Monday. It can be done, but back-to-back trips like that are risky, and we'd all be heavily jetlagged besides.
But last week BACnet Chairman Dave Robin changed the meeting dates to May 2 through 6, and this changed the whole picture. For my part, I will be able to fly home from the meetings Friday afternoon, spend Saturday & Sunday at home, and fly off to Europe on Monday (arriving Tuesday for the plugfest beginning Wednesday). East Coast folks attending both will have it a little more rough, at worst with only Sunday spent at home.
So I now have to fill out and submit the application, and start arranging my trip.
But it will be good. The plugfests are always interesting affairs. They're closed to the public to help foster a spirit of cooperation between groups who compete in the open marketplace (in the world of BACnet interoperability, we all win when our devices work together). There is always something to be learned, even for companies such as Alerton who have been BACnet for a very long time. And for new BACnet companies and new development teams, there is a lot that can be learned from others about the downside of making assumptions when developing.
As a participant in these events since sometime in the 90s, I have long urged all BACnet manufacturers to come and participate in these plugfests. The European plugfest is held every other year in the spring, the North American every year in the autumn. Nobody has ever, I think, come away without at leats one or two surprises.
The deadline to apply is tomorrow; if you are even considering attending I recommend sending an email ASAP to the BIG-EU Office, requesting a copy of the Invitation and Registration Form.
Hope to see you there!

When Models Collide
Our four Rapid Development Teams (Load, Energy Manager, Meter and Generator) are meeting to compare and align the models we've been developing for these four areas, the underpinnings of the entire "Facility" (residential, industrial and commercial buildings) model that represents the end consumer of the electricity generated and conveyed by the electric grid. These models are necessary for working out the details of the data communications that will alter the ways in which energy is generated and consumed, for greater energy efficiency and make best use of existing infrastructure.
On top of that, these models being developed were built on initial use cases, models and data elements drafted by the Energy Information Standards Alliance (aka EIS Alliance) over the last year and a half. This was to provide a structure that would allow various models developed independently to be more readily harmonized.
We have our work cut out for us.

Mark your calendar
The meeting will be held May 2 through May 6 at the Pacific Energy Center, San Francisco, (next to the Moscone Convention Center). Working groups will meet Monday morning through Thursday morning, and the plenary session Thursday afternoon and Friday morning.
Hmmm... since it will be difficult for East Coast folks to get home Friday at a decent hour, I guess they'll have the afternoon and evening to tour.
But I found this statement from the Pacific Energy Center interesting:
"The Pacific Energy Center offers educational programs, design tools, advice, and support to create energy efficient buildings and comfortable indoor environments. Most of our efforts are focused around commercial buildings..."I hope I can get a tour.

One week remains for BACnet public reviews
Addendum 135-2008ad: an 11-part addendum of miscellaneous changes.
Addendum 135-2008af: a 32-part addendum (this is a record!) of miscellaneous clarifications, improvements, changes and extensions. Most changes are to BACnet's alarm generation system, resulting from several years of "Alarm Summit" meetings.
Addendum 135-2008aj: Add backward-compatible support for IPv6.
You can download and comment on them here. Anyone can comment; you do not need to be an ASHRAE member or a member of the BACnet committee to submit comments.
I strongly encourage BACnet technical folks to review these proposed Addenda for any issues that the committee might have overlooked. If they conclude public review without comment, they will be deemed to be approved and will be published as part of the BACnet standard.
Conflict
Through this issue I learned that, sadly, I'm not going to be at this year's Facility Decisions conference in Las Vegas, scheduled for October 11-12. At that time I anticipate being in our BIG-EU meetings in Rome instead, and particpating in our BACnet Forum Rome.
In this issue BACnet International made a call for speakers for the conference, with session title and summary/learning objectives, by March 21st. This should be an opportunity for some. For me it's a pity, because I had been looking toward a new talk pulling together energy (efficiency), Smart Grid and BACnet, though I plan to still pull together material for this and am continuing to update "Energy Standards and Energy Efficiency."
If you're at NFMT in Baltimore this week, do visit BACnet International at Booth #1383 and say hi.

Low-level churn
But yesterday Dave Robin sent out the latest draft of a proposal to the IT working group. The part of the Subject line I could see in the Outlook pane grabbed my attention with the words "experiment" and "Atom" (processor?) in it. I just had to see what was going on so I opened it. First item, he was addressing both the XML and IT working groups, and I've not been involved much there. Then I saw the attached document included "New BACnet-WS Services" in the name, opened it and... Holy Cow! These folks have been BUSY! It would take quite some time to digest all this.
After that I went back through my emails and saw other groups have been busy as well. The spring meeting is going to be an interesting time when all this work bubbles up.

Engineering Week
But while exploring some music videos this evening we came across a recording of Frankie Armstrong singing a Peggy Seeger song, Gonna Be an Engineer, that I remember from sometime way back when.
When I was in college, women engineering students were rare; a decade ago in China I was stunned to see that half the engineers there were women. But things are changing here. So, in the spirit of Engineering Week, I dedicate this posting to elder daughter Beth, bona-fide and degreed engineer in her own right, and younger daughter Heather, on her way.
Enjoy.
Doomed
That is a major effort, as one can see here.
In the last meeting, in December, it was announced that the SGIP now had 634 member organizations (572 US, 28 Canada, 34 elsewhere), represented by 1750 individuals.
I am warned this is no small task; if elected, the time required will mean I will have to give up some other committee assignments, if only for the year's term (not renewable) for this assignment.
And writing my bio for this nomination was, um, interesting. The three decades spent at NASA and developing embedded systems are over -- just a quick overview of my participation on various industry committees' executive boards took a paragraph.
But maybe I'll be lucky and there will be other nominations. The current secretary is a really tough act to follow.
If there are, please vote for the other guy, okay...? [grin]

Tough week
On the other hand I think I am "done" with Olympia for the week, or maybe they're "done" with me, so now I can focus more on the class.
The class material is fascinating. I've long had one perspective on solving certain building automation issues, and now I am seeing a second -- similarities and differences.
I'll be back when my brain clears...

BACnet International AHR Expo presentations
This is great for me because I was so tied up with BACnet and Smart Grid meetings I wasn't able to sit in on the others, only catching the tail end of Steve Tom's "BACnet to the Rescue: Interoperability Saves a Troubled LEED Project."
(And ahem, I have one up there too. If you download and find it useful, drop me a note.)

BACnet International Journal 2
It's an excellent publication; from amongst the wide variety of topics and authors (truly international in scope with its mix of North American and European authors) I highly recommend David Fisher's "BACnet: To Be is To Grow" perspective on BACnet and its standard.
And while you're there, I would suggest signing up for BACnet International's newsletter, Cornerstones.

The really fast track
Pulling together the pre-publication drafts of the addenda about to be published, I discovered a new record had been set.
Now the usual process for getting a change proposal published used to be to have it reviewed and approved in a working group, then reviewed and approved for inclusion in a poublic review addendum, then an official vote for public review of the assembled and formatted addendum (which contains 1 or more change proposals).
However, I could not find Addendum ah anywhere in my meeting files. As best as I can tell it was seen and revised in a working group, then sent to the entire committee and voted for publication review as an addendum, the (editorial) formatting to be subsequently applied. This went so fast that the committee never saw the addendum draft -- the next time it appears in the record, it had been published.
Impressive.

Las Vegas Wrapup - Published
We received a report during the meeting that four new addenda have been approved by ASHRAE for publication. These are:
If you're developing BACnet devices that use the MS/TP LAN, use BACnet "Date" and "Time" for anything, use "Annex J" BACnet/IP, or are contemplating using the ReadPropertyConditional service, you should read these when they're published.
Addendum ab: MS/TP Baud Rates
Addendum ac: Using BACnet "Date" and "Time"
Addendum ag: BBMD B'cast Storms, and trend-related BIBBs
Addendum ah: Remove ReadPropertyConditional service

11 years of BACnet testing
Not that we're done, by any stretch. Many of the tests we've developed are being rapidly rolled into the BACnet testing standard; others are being reviewed and revised. And we have our work cut out in merging and unifying the testing and process between the two BACnet teting labs.
The committee's numbers have never been large: today's meeting with 14 members, from Europe and North America, is pretty typical.
But today's meeting was notable for the fanciest location yet, in the Vdara Hotel & Spa in Las Vegas (a LEED Gold building) -- although this picture didn't quite capture that.

"Why American utilities will overpay $2 billion for smart meters"
Not 100% clear on what these "smart meters" do, other than communicate meter readings back to the utility in order to eliminate human meter readers.
Why are American utilities spending twice what the Europeans do for smart meters? Why aren't they using joint standards and joint procurement to achieve economies of scale and drive down prices?
This screw-up will squander at least $2 trillion over five years. Who will foot the bill? As the old joke goes, one of three groups – ratepayers, consumers or taxpayers.
$2 billion may be understating things
Update: Francine has a great link in the comments.
An American friend working in Europe tells me the typical cost there is $40 per meter (plus $15 for the communications by the way). In America, he says, typical prices are $110 to $120 per meter (and about $50 for the communications). ...
One thing is clear: they're not "Smart Grid" meters. At least not the Smart Grid being developed by NIST's Smart Grid Interoperability Panel under White House direction. We are still defining the data and interfaces for residential, commercial and industrial buildings! So in a few years these meters might have to be replaced anyway.

The Russian Standard
I think it's pretty cool. Even if I can't read much of it (but I can read more of this than I can of the Japanese, Chinese and Korean translations -- at least I can sound out a little of the Cyrillic alphabet; the first word is very obviously "Protocol"). I think Andrey said he's bringing a copy to Las Vegas; if so I will be very interested in seeing it.

This has to hurt: "California County Bans SmartMeter Installations"
kiwimate writes:Privacy is a big topic in the SGIP Smart Grid development effort, one not yet fully resolved, but this has to be an "ouch" for the folks involved."Marin County in California has passed an ordinance (PDF) banning the installation of smart meters in unincorporated Marin. Among the reasons given are privacy concerns associated with measuring energy usage data moment by moment and the potential for adverse impact on emergency communication systems used by first responders and amateur radio operators. The ordinance also comments that 'the SmartMeters program ... could well actually increase total electricity consumption and therefore the carbon footprint,' citing 'some engineers and energy conservation experts.'"The ordinance also mentions "significant health questions" raised about "increased electromagnetic frequently radiation (EMF) emitted by the wireless technology in SmartMeters."
