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 an incentive to conserve.

Save3: Save Power! Save Water!! Save Money!!! Encouraging hotel 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.

Water Consumption monitoring: Every room has a main water-inlet. For connecting this with the Save3 Keycard Switch, a valve is introduced at the inlet and that couples wirelessly with the switch. It sends information about the amount of water used to the switch.

Electricity Consumption monitoring: For monitoring electricity consumption every room has a wireless enabled electrical meter and that sends information to the switch.
Save3 Keycard Switch: Save3 Keycard switch is wirelessly connected to Water and Electricity Consumption monitoring systems. The information provided by these monitoring devices is displayed graphically as LED rings viz., Aquamarine coloured ring for water and amber coloured ring for electricity consumption.

This connectivity amplifies the capabilities of these smart objects and the information is made visible when the Save3 Keycard is inserted in the switch.
