    THIS IS A ROLAND PIQUEPAILLE ARTICLE
    Here is the "short summary":
    The Rise of Smart Buildings

    In a very well-documented article, Computerworld describes the current status of building automation systems (BAS) that control heat, air conditioning or lighting and how these systems are merging with traditional IT infrastructures. Computerworld writes that they're not enough standards in this industry and asks a fundamental question: who will administer these building networks, IT or facilities managers? Take for example Yale University which wants to connect 210 campus buildings, but also wishes "to integrate the BAS with the university's accounting system for billing and chargeback." Imagine the security risks involved with such an approach. Read more...

    Let's start with a an assessment of the current situation.

    As building automation systems (BAS) that control heat, air conditioning, lighting and other building systems get smarter, they're converging with traditional IT infrastructures. Emerging standards are enabling data sharing between building systems as well as with other business applications, improving efficiency and real-time control over building operating costs. Information security concerns, immature standards, the reluctance of vendors to give up proprietary technologies and ignorance among IT professionals of the convergence trend are all slowing the pace of this transformation, but it's gathering momentum.

    But who will control such networks? And are there enough standards in this industry?

    Open standards are just beginning to evolve and will likely break down the silos between building systems ranging from physical security to elevator controls. And the data from those systems is likely to be shared with other business applications such as the accounting system. This will allow for more-efficient buildings as applications are developed that can capitalize on newly converged data streams and real-time access to data.

    [Right now,] standardization has started from the bottom up. Proprietary cabling systems in networks that link sensors and other devices to controllers on individual floors have given way in recent years to two competing, open protocols, BACnet and LonTalk, while floor controllers are migrating onto IP backbones.

    Barry Haaser, executive director of LonMark International, says LonTalk and BACnet will prevail at the device level for technical and cost reasons. Others aren't so sure. "Instead of two guys running the IT and controls networks, why not one guy? I see IP going down to the individual device," says Anno Scholten, chief technology officer at BAS vendor Plexus Technology Ltd. in Irving, Texas.

    IT infrastructure used in building automation systems This diagram shows how "building automation systems today rely on open, industry-specific protocols such as LonTalk (shown) or BACnet for device-level communications. But they increasingly leverage Ethernet and TCP/IP for home runs back to the control systems." (Credit for image and legend: Computerworld).

    Let's take the example of Yale University to see how complex can be the merge between control systems and IT infrastructure.

    But sharing the IP backbone raises security concerns among network administrators. Yale University is starting a project to consolidate its BAS onto an IP network that will link 210 campus buildings, and it plans to tie the BAS into a room-scheduling system that will automatically control energy usage based on room occupancy. For security reasons, Bill Daniels, manager of systems and technologies for the university's facilities group, has created an isolated, parallel network that's protected by firewalls and uses nonroutable IP addresses to keep data off the Internet.

    Jerry Hill, director of systems engineering at Yale, says security is paramount. "We don't want a student to hack into our building management systems just beca

      Don't be so cocksure about that. I'm part of a group of buildings professionals that provide infrastructure support for a major telecommunications carrier, and I can tell you for certain, our pay grade is superior to that of most IT managers and engineers in the company.

      With regard to BAS systems, they are far more complex than networking gear. The systems we support typically employ a wide variety and large number of sensors, communicating on different protocols. The code is customized for each facility, since it must interface with and control equipment from multiple vendors. These systems require maintenance and troubleshooting skills atypical of most IT professionals.

      I shudder at the thought of IT maintaining our BAS systems. One thing most of the IT professionals I've assisted over the years fail to realize is that electrical and mechanical infrastructure are the underpinnings of the rest of the facility. When you're out of power or cooling, you're out of business, plain and simple.

      Actually, it's funny you spin it this way. Because in the current state of affairs, highly trained technicians handle these things because it's not "simplified for less qualified" IT personnel or otherwise to handle. These technicians are higher paid than the IT staff. Now this mainly has to do with these systems developing entirely separately from IT (ie the HVAC industry really had no incentives to make their systems IT friendly, nor did they really know otherwise - so they just developed the systems themselves).

      But, despite what you may think about having an IT person jump right on the job because the system 'seems similar' to what they work on, the type of specialized training involved in dealing with building systems is much different than typical IT work. I would think at least a year-long training program would be required before anyone could become an apprentice. And then another year or two of on-the-job training before you are fully qualified to work on your own. If your project hiccups, fine... you might lose some sales, computers might go down temporarily, services might be unavailable. If your building systems hiccup, you might burn a building down, hinder hundreds of people from doing their jobs, or damage millions of dollars of equipment, samples, resarch, etc. Need me to prove my point? Give most IT staffers a wiring diagram, and they'll scratch their head and ask you what the hell it is ...

    I hate this so much. When I was in school, physical plant had control of the central air/heat in our building. They were in a small office next to a warehouse. I spent most of my time in a five story building on the other side of campus. They decided when our a/c went on. We could call them, but we'd be lucky if they actually listened. There were lots of people in our building 24 hours per day. Good luck getting the air turned up in the middle of the night. Ugh.
    • Similar experience here. Our compsci building has lights and air controlled by one of these "smart" systems. It's a new-ish building and we've been suffering since we moved in. Lights turning themselves off when we aren't moving enough is bad, but the worst is the cooling. Apparently the idiots who setup the system didn't think labs full of P4s running 24x7 needed to be cooled when there is no one jogging around the room.
    • In the building where I work, the lights go off automacilly at 6:00 pm (7:00 in the summer). If you're working late, they have a number to call where you can punch in your zone number and the lights will come on for that section for another 2 hours.
      The main problem is that at 6:00 everyone is trying the number at the same time, so it may take a half hour or more of redialing in order to get the lights back on.

    I'm an IT person. I've seen a couple of these systems. In general, they use networking simply to transport data between HVAC controllers.

    In my experience, the customers have multi-building networks. Within each building, all the HVAC sensors and controls are all wired to a central control device, not over the network. The control device is typically some solid-state box bolted to the wall, not a PC.

    All these boxes talk back to a central server (crummy PC with BAS software) over the WAN. The server then tells the boxes what to turn on and off and sends out alerts if something goes wrong. The alerting is basic, no SNMP or emails. A pager if you're lucky, but probably just a flashing message on the screen. My understanding is that there are some default settings the boxes can use if they should lose connection to the server.

    As for this being an area for IT to take over, I don't see it. The vast majority of the work involved is with wiring HVAC sensors and systems back to the controllers and in programming the settings into the BAS software on the server. There is very little IT knowledge required. If you can program a cable modem router, you probably have enough IT knowledge to program the IT part of these things.
    • Sounds a bit like ours. Relatively dumb HVAC controllers, each building has local fall-back, network failure != building failure. All on their own VLAN on the common fibre. It is coupled to the room booking system, if a room is booked HVAC looks after it. Lighting for lecture theatres, etc, has occupancy sensors and the dreaded 30 minute cutoff, but this does not apply to toilets, stairs or faculty staff offices.

This allows for remote monitoring and control. Better yet DALI can be wired using standard 240v insulated cabling and can be run next to the mains wiring (no segregation).

    I work within an industry that would supply some of the stuff to be used in so called "Smart structures" I've been to the conferences, I've talked to the people.

    It all falls apart because of cost. I can control anyone of the different systems in your house/building, I can monitor any variable you want. But the cost point is much much higher than you would expect. Even for a small 2000 sq foot house to monitor each room, control lighting and so forth would cost tens of thousands of dollars installed.

    Then it still wouldn't work well, because I can only monitor so many different variables, and there are too many exceptions.

    For instance. I worked in a semi smart building. Part of it was that motion sensors turned the lights on and off. If it didn't sense movement for 5 minutes or so it shut off the lights.

    All well and good until someone is in the bathroom alone for a legngthy constitutional. Then your trapped on the can in a dark room.

    Yes a minor example, but just one of many thousands of issues that come up. Say heating. You want to lower heating in rooms that aren't used, so you lower the temprature. Then someone comes in to work for an hour or two. Well rooms don't heat up immediately, so while the system is trying to heat the room up, the person says, "It's to damn cold in here" and goes somewhere else.

    Or the opposite, you turn off the air conditioning, then people avoid that room because it's hot and muggy, next thing you know you've got mold in the walls.

    All for a system that costs tens of thousands of dollars for a small building, hundreds, or millions for a large building.

    As to networked appliances. Who want's to update the software in their toilet so they can use their microwave.

    Who wants to find out out their boiler has a bug that shuts it's down under certain conditions, only to be told.

    "It's a known problem, it will be fixed in the next release."

    Who wants to have to re-boot their stove.

    For some things simple analog controls work fine, things like on/off switches, potentiometer based volume knobs, and tuning knobs.

    I can't stand the current generation of car stereos because the volume goes in steps, either just a little bit too loud, or a little bit to quiet. In the old days I could fiddle with the tuning knob to get in a hard to reach signal. Now I can only go up or down .1 Hz, if that doesn't work, give it up. I don't want everything else to be a similar way.

The truth is, BSMS systems are dumb - they are pre-programmed and (at best) report. No-one (esp. the investors) is actually interested in spending for IP addresses for the windows on the Arts wing, the necesary actuators and so on. I can monitor these things only because the necessary sensing is already part of other systems - like the alarm systems.

    To everyone who wants to set off the sprinklers at their High School: please realise that sprinkler heads are purely reactive and work solely on rate-of-rise of temperature; they are not remotely addressable. Smoke sensors, on the other hand, can be ;)

      sprinkler heads aren't even electronic. They have metal plugs that melt at a given temperature, which releases the water and the pressure drop by one sprinkler going off usually will set off several others in the same area or zone. The pressure drop is also detected by pressure monitors hooked up to the fire alarm system.


    • In the UK we call such systems BMS, Building Management Systems.

      Pfft. Talk to me again when you have a similar system set up and successfully running in a refinery or other similarly complex industrial facility like a chip fab.

      Architects are always a pain in the arse - style minus substance and they rely on their civil/structural subcontracted engineers to do the heavy lifting.

      Think the "oooh, shiny" client response phenomenon; that's essentially the market that architects cater to.

    For those of us out there who aren't in this particular field, what would really help would be some controllers and other types of devices that can be plugged into a fast ethernet/GigE network, given an individual network address, and which can be used to monitor temperature/humidity, turn on/off outlets, turn on/off switches (relays), log temperatures, or similar functions.

    No offense, but the majority of the posters so far have no CLUE what they're talking about. I work for one of the largest building automation companies in the US (and world) and write the logic for programmable controllers. First of all, there is no way you'd EVER want an IT department taking control of your HVAC system unless they've been trained VERY well and their building's controllers were programmed with an IT department in mind. I started off in the IT world, and thought moving to building automation would be a cinch, but let me assure you, there was a huge deal to learn. When you're dealing with Chillers that can blow a cap that costs $10,000+ to replace, just because you accidentally allowed a chilled water valve to open up while your return water was still too hot after the a switchover in your 2-pipe plant... well... let's just say you want a building maintenance guy dealing with these situations. As far as standards go, just because IT people don't know about them hardly means they don't exist. The most prevalent standards today are the ones mentioned by the article - BACNet and LonTalk. Both are fairly simple protocols that allow for efficient communication over a wide range of network media. They were designed with slower networks in mind, so that if your bandwidth is only 100k/sec, you're still going to be fine. Usually the controllers are on a slower copper wire network, and then routed through an ethernet network to the frontend computer. Personally, I'd like to see the business go towards using standard ethernet and tcp/ip the whole way through, because of the lower costs of standard routers, repeaters, bridges, etc. As far as security concerns go... If they're worried about someone hacking in to their HVAC system and harming things, then their system was progammed shoddily. A well programmed system always takes into account the stupidity of users. You place safeguard upon safeguard upon safeguard. Even guys that have been facility managers for years will try to do stupid things, so you plan ahead and only let them make non-harmful changes from the frontend.
    • Whatever. For as many buildings as you're talking about, there are probably a hundred others stocked with Ye Olde Electronicke Door Lockes et al that are run by whatever non-doofus "I don't need a manual to program a fucking VCR clock" types are handy. And those folks don't know - or particularly care - about the work involved in lowbrow facilities management.

      You keep the low voltage protocols off the internet. You use a gateway. Cllearly, obviously, you do not want the internet in the middle of a process control loop.

      One should think of a process control system (HVAC for the 3rd floor) as similar to a RAID sub-system. Multiple moving parts. Different devices computing their own sectors, timing, etc. Servo motors have their own control logic that manages spin up, spin down, head stepping. A supervisory RAID system manages striping, adding hot-spares, etc. All

    The last thing we need is automated building that are tied into computers.

    I was having a conversation last night with a friend about how annoyed I am with the current crop of auto mechanics. I have a minor problem with my vehicle that I can't diagnose, but the shop won't even look at it.
    Why?
    "Because it isn't throwing a code."
    Just because the check engine light isn't on doesn't mean there isn't a problem. The last thing we need are building supers who look at their computer screen and say, "I don't see a problem", because the water leak up on 17 hasn't gotten big enough for the computer to notice it.

Our facility is just over 1,000,000 sq feet and is comprised of 6 buildings including a data center.

      Amazing yes, usefull no. And contrary to what this is supposed to do, which is reduce energy costs, burning a bulb/bulbs you don't need is wstefull.

      More usefull is the motion sensor I have for the bulb in my carport. When I pull in it lights up so I can get in the house, and flip that highly complicated analog switch to light the inside house.

    There is a very old snapshot of how it was configured when I was in New Mexico at Barnnet [certsoft.com]. It is setup in a similar manner here in Oregon, but the HVAC system uses A/C instead of a swamp cooler.
