Energy management in hotels is a challenging issue for owners. From the desired temperature to their favorite light level, guests are more likely to return for another stay when they can customize their room to suit their preferences. However, providing these features using old technology wastes a lot of energy. For instance, there are a lot of problems with the old card key switches. Guests can put any card in the old switches, or they might ask for more than one card. Even if hotel desk refuses to give more than one card to a guest, she/he might claim to have lost the card.
There is also a lot of overconsumption of lights and AC energy due to things running even when guests aren’t in their rooms, and this can cause a financial loss for the owner. Of course, no hotel owner wants to prohibit guests from having a comfortable stay, nor do owners expect guests to enter a dark or cold hotel room. No one is to blame. Both guests and hotel owners have the right to fulfill their interests.
Some hotel owners think if they separate the AC from the main network, less energy will be consumed, while others think that motion sensors are the solution. However, these approaches fail to resolve the problem. The AC is the most energy-consuming device of all, and motion sensors can be nightmares since they only function based on movement detection, meaning that the AC and lights might go off while a guest is sleeping or reading a book. Nightmarish!
The TIS Automation Company offers the best solution for hotel guest rooms by introducing its innovative technology in a smart ceiling sensor: Energy Servant.
Our Energy Servant blows past classic hotel card switches with its ability to detect human presence in a room. This ceiling-mounted sensor has many options, including a PIR motion sensor, a light harvest sensor, 2X digital inputs, infrared emitters compatible with all split AC types, TV brands infrared codes, temperature sensor, 24X flags, and 32 lines of logic and timers.
By installing this door sensor at the entrance to a room, connecting it to the Energy Servant’s digital input, and programming the logic lines, the problem of room occupancy is totally resolved.
The following logics can be defined for this sensor to manage room energy without any discomfort for guests:
Logic 1: If there is any movement in the room, the occupancy mode will be on.
Logic 2: If the main door is opened and closed, a flag will turn on for one minute to check if there is movement in room. If no movement is detected after one minute, the system will activate energy-saving mode. This is useful in situations when a guest enters the room briefly.
In energy-saving mode all lights are off except for a nightlight, which stays on for 3 hours in case there is another guest taking a nap. Also, the AC will not be turned off, but its temperature will be decreased by 2 degrees. This helps save energy over time.
Logic 3: If the energy-saving mode is enabled and no movement is detected for more than 3-5 hours, the nightlight and AC will be turned off automatically. It is also possible to define lower temperature levels for the AC.
In addition, the Energy Servant can turn the AC on/off if it recognizes that a balcony window/door is open. All this requires is adding a magnetic contact linked to the balcony window/door and programming the desired smart decision.
The light harvest sensor helps save energy by turning balcony lights off if there is enough natural light.
Another practical and beneficial capability of this sensor is its built-in thermostat, which helps maintain the right temperature at all times. This is important for keeping furniture fresh and intact. Also, in hot spots and even if the room is empty for a long time, humidity and bad smells will not become a problem in the room. This sensor can be programmed to alter AC to dry mode if the room temperature reaches or exceeds 28-30C degree. This can happen several times during the day if needed. A similar performance can be programmed in cold spots to prevent mold.
Another option of this smart device is TV control. If the hotel provides the guest with a room tablet, she/he is able to control the room’s TV with it.
This sensor was installed in 20 rooms in the Fairmount Blue Mountain Hotel in Sydney. The result was considerably enhanced energy management and many satisfactory comments from guests who enjoyed their luxurious stay at this hotel.
TIS offers the chance to meet both hotel owners’ and guests’ interests and needs with just a few items and in the most energy efficient way possible.
