Energy usage remains the second-largest cost for hotels, behind labour. The cost of electricity will only continue to rise. On average, 90 percent of wasted electricity usage comes from the guest room, which can be a property’s most unmanaged resource and a guest room Air Conditioning/Heating (HVAC) system can represent 70 to 90 per cent of that wasted electricity. Conservation is becoming the cheapest and easiest solution, says the door access control product company Salto.
The company’s Universal ESD system allows hotels to optimise energy consumption by turning off lighting and adjusting climate control systems when guests are not in the room for a long time.
The hotel HVAC and lighting systems receive room status (occupied/unoccupied) from the sensors and, as a result, activate or deactivate the room’s lights, air conditioning or heater while maintaining a comfortable temperature (as configured and preset by management). The product uses infrared detectors and wireless technology. Installation and set-up takes about 20 minutes, the product firm adds, so your guest rooms remain available for sale.
How it works
1. Detects whether or not a guest room is occupied through information transmitted to the Universal ESD control module by the passive motion infrared detector and micro door sensor.
2. When a guest room is occupied, the system allows the guest to have full control over all temperature settings and lighting.
3. If the system detects an unoccupied guest room, the operation becomes regulated by the control module, which initiates your customised energy-saving settings, for temperature reduction, for example.
4. Unoccupied guest room temperatures are pre-determined by hotel management, allowing control over electricity usage while maintaining maximum guest room comfort.
When the guest room is occupied
1. Guest enters the room and the door micro switch ‘knows’ the room is occupied.
2. Motion wireless detector detects movement.
3. System is in “occupied” mode, so the guest has full control of heating, cooling and lighting.
When the guest leaves the room unoccupied:
1. Guest leaves the room and the door micro switch “knows” someone may have left the room.
2. Motion detector “looks” for movement for the next 60 minutes (or a duration set by property management). If movement is detected, the system remains in “occupied” mode.
3. If no movement is detected, the system goes into “unoccupied” mode, turns off the lights and sets the air conditioner or heater to a temperature preset by property management.
