Self-Powered Hotel Energy Savers

With the climate crisis (literally) heating up, oil and gas prices still at previously unheard of levels and the economic outlook uncertain, we’ve all started to get interested in ways to save. I’m a big believer in finding synergistic ways to improve our lives. (See my entry on triple plays – ways of saving the environment, money and your own hide all at once – for details.) So I was interested when a reader wrote in asking for feedback on his startup idea for painlessly saving energy in hotels.

The venture is called RoomEnergy and the chief product is a card reader that controls the flow of electricity to all of the systems in the room (lights, TV, HVAC). I’ve seen these kinds of things in operation in Europe. When you arrive in the room, you put your key card in the reader and all of the systems work as expected. When you leave, you take your key card with you and everything is powered off. This makes it easy and painless to be environmentally responsible without ever worrying about leaving the lights on or adjusting the thermostat. And it incidentally provides a convenient spot by the door to place your key card so you won’t lose it.

Hotels benefit immediately as well as they save on electric bills. The brilliance of this particular solution (apparently imported through a company called enocean) is that the card reader is both wireless and self-powered. This means that the installation takes about 5 minutes and there are no batteries to run down. The reader can literally be placed anywhere and requires no wiring and no holes in the wall. It actually uses the energy generated by inserting and removing the key card to power the signal to the switch to turn the power on and off. That is way cool. and it should make it a no-brainer for hotels. Want to start saving money and being green with almost no investment? Sounds good to me.

Troy Davis, who wrote in about his startup, was concerned, though, about the reaction of hotel guests. He realizes that the thing that could kill this idea dead would be if hotels thought guests disliked it or found it confusing or difficult to use. He said he’d been socializing the idea with friends and many of them thought (in his words), “they don’t worry about conservation on vacation or business trips and at $120+ per night they should be able to have the AC on minus 20 if they want to.” I confess the first time I ran into one of these devices in a hotel in Portugal I was confused as to why the lights and TV didn’t work. The card reader wasn’t labeled, though, and once it was explained I thought it was a great idea. And my guess is that the savings to hotels will be compelling enough that the devices need only be inoffensive to guests rather than a perceived benefit.

So now that I’ve biased you with my thoughts, my questions to readers of User>Driven are these:

  1. What would your reaction be to a (properly labeled) device like this in your hotel room?
  2. Would it make any difference if your stay was business or pleasure?
  3. Can you think of ways of making the device more convenient, intuitive and/or palatable?

Post your thoughts as comments below and let’s help this idea along.
