Key card switch for hotel


I don't get the usefulness of it. I get the turning on part, but how would it know how to turn off? When a guest open/shuts the door? Not a good idea. Let's say the guest turns the lights on with the card, then decides to run to get some ice. Props the door with the lock, comes back, closes the door, the lights now go off.

If you have to insert your key card into a different reader inside the room to turn the lights off, it's no different than a switch. You are relying on the guest to turn them off. Some will turn off the lights, some won't, either way, the maid will be in shortly.

The guest puts the key card in the reader, and leaves it in the reader. As long as card is in reader, the electric is on. Since its the same card as the entry card. When the guest leas the room to go out to meeting or amusements, the device turns the electric off after the card is removed for 15 seconds.

In areas whee electric is over 20 a KWH, this can save a large amount of money over a years time.

Imagine 300 rooms using just 70 less KWs an hour for 6 hours a day. It would be an operating cost eduction of over $9,000.00 a year at 20 cents a KWH.

At your numbers, that's $30 bucks a room. Imagine the cost to retrofit a hotel. Between labor and materials, I think you are looking at about 500/room minimum. A new install would be cheaper, but $200/rm would be a low average in my mind. So, that would mean that these would have to save $30/year for 7-16 yrs to pay for itself.

I would think something like this would be done during a planned renovation. Where the walls are going to be opened up already. Not just on a save money whim.

More than double what we pay here, but there are areas in the US that have much higher rates these days, due to recent mandates implemented by the EPA with the loss of coal-fired power plants ...

In the Cayman's, they pay 37 cents a KWH( thats info is from a friend 2 years ago). Its expensive to run those diesel generators.

You have to use your room key card to turn on the lights and you have to leave the card in the a lot for the lights to stay on. So you remove your key when you leave or you can't get back into the room when you return.

(Sorry - just saw that someone posted this same thing)

Well, apparently someone has done some math that shows these systems are worth it, because you will find them in lots of hotels in Europe. Obviously new construction is the simplest way to implement it.

People are mentioning things a system like this can turn off - lights, TVs, etc. It also can turn off air conditioning, which uses lots of electricity.

Or it's another feel good product pushed by the energy conservation crowd. This is the good old USA however, if there is a true need for it, the market will show demand for it. I'd hate to see the government mandate things like this however...I'm talking to you California.

honeymooned in jamaica, the patio door in the hotel room had a switch on it that turned off the a/c if the door was open.

They do not open the walls during a renovation, unless they find signs of mold or damage.

Rarely do they just gut the whole structure, while it is in operation. If they did, they would loose thousands of dollars in revenue.

Majority is just cosmetic, ADA required, along with conforming with newer state standards for burn time on furnishings and carpets.

Many have off seasons. Which is when a wing will have planned renovations done.

Cruise ships do that as well. Not that it matters as most of the time their A/C sucks anyway.

While it sounds like a good idea, there are too many here in the USA that don't like being told what to do regarding conservation. Call it a backlash at the way it has been forced down our throats by the anti-capitalism crowd masquerading as conservationists.

People here would simply get a second key.
