Imagine you are staying in a big hotel with lots of rooms and lots of people. In order to keep everyone comfortable, the hotel needs to use a lot of energy to power things like the lights, heating and air conditioning, and hot water for showers and sinks.
Hotel energy management is a way for the hotel to use its energy in a smart and efficient way, so that it doesn't waste any energy and can save money on its energy bills. This is important because using too much energy can be bad for the environment and can also cause the hotel to have to charge more money for its rooms.
One way that hotels manage their energy is by using technology called "smart thermostats". These are like little computers that control the temperature in each room. When the room is empty, the thermostat can turn off the heat or air conditioning so that it's not wasting energy on a room that no one is in. When someone enters the room, the thermostat can turn the temperature back on so that the person is comfortable.
Another way that hotels manage their energy is by using energy-efficient light bulbs. These light bulbs use less electricity than traditional light bulbs, which means that the hotel can save money on its energy bills. Some hotels also use sensors that can tell when someone is in the room and turn the lights on and off automatically.
In some hotels, they also have systems that recycle the waste heat from the air conditioning or heating systems. That way they don't waste any energy and can use it to heat up water or keep other parts of the hotel warm.
Overall, hotel energy management is a way for hotels to be mindful of their energy usage and take steps to reduce it wherever possible. This not only helps the environment but also saves the hotel money, which can then be passed on to guests in the form of lower prices.
