Save3

Save3 is a visual feedback system designed for hotel rooms. Comprising a set of smart objects, this system subtly encourages guests to save water and electricity by monitoring consumption and by providing incentive to conserve.

According to a UNWTO report, hotel facilities rank among the top five in terms of energy consumption in the tertiary building sector. Most hotels, besides being big power guzzlers, are also huge on water consumption. Hotel resource consumption is influenced by both physical and operational parameters. An important operational parameter is the behaviour of guests towards resource consumption. 

As the charges for a hotel room include the water and electricity costs, guests are often less cautious and tend to overuse these resources. However, people, even if not particularly concerned about the depletion of natural resources, are always very cautious about saving their money. So Save3 takes advantage of this inherent behavioural tendency. It is designed as a system that subtly encourages guests to save water and electricity.

The Save3 system comprises a keycard, a switch and wireless monitoring devices. The keycards and switches are Smart Objects with extended capabilities – besides accessing the room and regulating the electrical services, they are also routed in the electricity and water supply. Both the main water-inlet and electrical metres of each room are wirelessly enabled. This connectivity allows information about water and electricity usage to be recorded, visibly transmitted and stored when the Save3 keycard is inserted into the Save3 switch.

When a guest enters the hotel room and inserts the keycard in the Save3 switch for the first time, the indicator bars are at a maximum, indicating the estimated maximum resource usage provision for the period that the room is booked. The indicator gradually shortens as water and electricity are consumed. Now, a guest can pay the usual charge for a room when he checks out, but he will also be entitled for a part-refund, as an incentive, if he consumes less electricity and water than estimated.
