Energy Management in the Hotel Guestroom


With a global focus on being “green”, there are many initiatives being put into place to save energy. However when it comes to air-condition/heating, or anything else involving hotel guests, most hotels are doing the same things they have done for years.
After employee’s salary, the highest operational cost for a hotel is electricity and there is a huge potential for electric cost savings if you do the right thing. Today, the most common way to save electricity in the a room is to have a keycard slot on the wall which turns the power off when a guest leaves the room. This is a failing method for energy savings as guests who are used to staying in hotels with these devices know that they can get around this by just inserting an extra card in the slot even when they are not in the room. Surprisingly, some hotels are even giving out extra cards to use in the ECU at the wall.

There are many better ways to do save energy, which are both more efficient as well as enhancing to the guest experience.
Since most hotel guests are not in the room except for when they are sleeping, the clue is to make sure there is no unnecessarily electricity usage when the room is not occupied. If you use motion sensors in the room that link to the guest room door lock, you will be able to monitor if rooms are occupied or not without any distraction to the guest. As soon as the room is not occupied you can make a set-back which reduces energy use significantly on both heating/cooling and lighting. This practice can save up to 40-50% of your energy in the room and the guest will never notice any changes.

If you want to invest in energy management like this, it’s important to do the ground work properly. First, you need to know how you measure electricity consumption in the room.

Then, you need to look at the component using most electricity and not spend a lot of time trying to control something that is not consuming much electricity at all. Some items have much lesser consumption than most people believe, such as an energy efficient television set.
By identifying the most critical items in the guest room you will be able to save a huge amount of electricity just with a small investment. An investment you probably will have a ROI on in less than two years.
