How to calculate the energy consumption of hotel rooms?

Hello, the energy consumption of guest rooms is generally divided into electricity consumption and water consumption. Other items (disposable items, bedding) are not included.

Power consumption

In the lighting part, spotlights, energy-saving lamps, T5 light bars, LED light bars and other lighting equipment are used indoors, and the overall light source with lighting and background effect is configured, with power consumption within 2.5 kW/h. There is also a power supply part (socket). The guest room socket mainly supplies power for refrigerators, hot water bottles, electric irons, televisions, computers, table lamps, floor lamps, table lamps, hand dryers in toilets, toilet flushers and other equipment. The peak power consumption of these appliances is within 3 kW/h. In the case of central heating water and central air conditioning, when there are instant heating equipment and split air conditioning in the room, the electricity consumption of the room is less than 5.5KW/H, and if split heating water and split air conditioning are used, it will increase by 4 kW/h.

water consumption

The consumption of hot water in the standard room is two persons/time, with shower of 40-60l and bathtub100l. When the hot water is above 60 degrees Celsius, the cold water accounts for 30% of the water, that is, when each room uses a shower and a bathtub at the same time, the hot water is about 130 liter. The cold water is about 30 liters.

Power consumption and water consumption are the main energy consumption of hotel rooms.
