Buildings Could Save Energy By Spying On Workers

Galactic_grub writes "In the future, your place of work (or apartment) may very well spy on you. But that doesn't mean it'll be able to name and shame you for all your nasty habits. Researchers at Mitsubishi Electric Research Laboratory (MERL) have devised a 'dumb' surveillance system that monitors the movements of workers without identifying them individually. The idea is to have a computer system automatically configure the air-conditioning to save money, or illuminate the most appropriate escape signs in an emergency."

Emergencies?

illuminate the most appropriate escape signs in an emergency.

Well, I would illuminate all escape signs in an emergency, infinitesimal energy savings be damned!

Which is why you don't work at MERL. In large, complex buildings, having only the signs that lead you out of the building in the quickest possible way would definitely be a benefit. Especially if, for example, one particular exit route was blocked for any reason.

I hope by "appropriate" they mean if a building is on fire and one of the escape routes like a stairwell is on fire, it will redirect them to a safer place.

Fair enough, if they have the sense to make it so that the default is ON. Lost connection somehow, sensors not responding for any reason? It lights and stay lit.

Still too failure-prone. What if the sensors are responding but buggy and they actively tell the signs to be off? A major disaster requiring evacuation could cause all sorts of things to go wrong.

The most robust systems are usually the most simple.

The biggest problem, IMHO, with emergency evacuation is a little fact that is often overlooked: people tend towards exits with which they are familiar. If you have two main exits and four emergency exits which trigger an alarm, nearly all people will automatically take the two main exits because they are comfortable entering and leaving the building through those entrances and exits. The four emergency exits will almost never get used. The only exception is a situation where you have to pass right by the emergency exit to get to the main exit, and even then, most people will be reluctant to use the emergency exit.

Similarly, stairs that culminate in an emergency exit door will almost never get used because people usually won't use them to get between floors and can't use them to enter or leave the building. As a result, only a small percentage of people will know where they are, and even fewer will know those stairs well enough to take them in an emergency. The rest will be too afraid of getting turned around and going the wrong way.

Making this even funnier is the corollary: nearly every alarm resulting from use of emergency exits is a false alarms. (A large percentage are either A. shoplifters at department stores or B. small children.) That makes the automatic alarm a complete waste of resources. You are far better off with a normal door and a pull handle.

What does this mean for emergency preparedness? Simple: you should NEVER have an entrance or exit that is "for emergency use only" unless it leads to an unsafe area such as a rooftop. All exits should be clearly marked and USED REGULARLY. Workers should be encouraged to frequent the entry/exit stairs closest to their offices/cubicles whenever possible, and to enter and leave the building through the most direct route, which by definition means that the most direct route cannot have one of those stupid "alarm will sound" bars on it.

If every emergency entrance and exit were turned into a normal entrance/exit with a pull handle and were used in the normal course of entering and leaving buildings, the typical time to evacuate a building in the event of an emergency would drop dramatically. If you'd like to take the easiest possible step towards making your workplace safer and you have an emergency management team at your workplace, point this out to them, and ask them why safe entrances and exits are marked as being for emergency use only. If they can't answer that question, ask that they change the doors into normal entrances and exits, then continue to nag them at every opportunity until they do so. You may not successfully change anything, but at least you'll get them thinking about the problem.

Already exists

[fwice]

My company already has this. Lights / ventilation run only from 6:30 AM to 6:30 PM. At that points, the lights / hvac goes out. But if you are working and want to reactivate these systems, there is a webpage (and a phone extension) that you go to, input your office location, and voila -- the systems come back on.

and according to the company, its dropped costs by a third.

About this summary and article...

[lpangelrob]

This is the most optimistic writing on infrared motion detectors I've read in a long, long time.

I'm sorry Dave

[spun]

I'm afraid I can't allow you to turn that light on. My cooling systems take precedence over the illumination needs of primates. How can I compute your optimal escape route in case of a fire if my systems are overheating?

You'll just have to pee in the dark, Dave.

Exactly

[Moraelin]

Exactly.

I mean, in most emergencies I can think of (flood, earthquake, tornado, whatever), you can pretty much bet on something being, you know, _damaged_. What if it's a sensor, or one of the hubs for this monitoring thing, or whatever? I can easily imagine someone getting lost, or trapped because they were too slow to evacuate, or end up with a stampede, just because the computer thought there was noone on that floor.

Heck, common sense says that something will be damaged even if nothing goes wrong. E.g., an escape sign will have a burned lightbulb. If the one at the other end of the corridor does light up, maybe I'll see that one.

Spying?

[TimmyDee]

How in the hell is this spying? All they are doing is taking a rough estimate of the number of people in the room and adjusting the AC/heat (and I did RTFA). No tracking. No identification of individuals.

It sounds to me like this story got trumped up with a privacy scare to get some reads.

You think that's bad?

[Slur]

I worked at a place where our floor, 7 1/2, had been left too short, so everyone had to crouch down all the time, and I was relatively tall. In an emergency the quickest way out was through a hole that led to being John Malkovich for ten minutes. You can imagine all the mayhem. It was hellish.
