An ‘invisible’ display behind the bathroom mirror lits when any tap is opened showing instant and accumulated daily water consumption. Three out of four people react favourably and, as a result 8-15% water is saved depending on building type. (For example 11% in hotels). Half of the water saved is hot, so there are energy & CO2 savings associated too.
The ‘remaining amount of water’. This is especially useful when the total amount of water used is roughly known, for example a household, or a school (fix number of daily users). It engages people to achieve the target which can then be reprogrammed to tougher goals.
Shorter showers instead of baths, not leaving tap running while shaving, tooth brushing, soaping in the shower, not using the toilet as a paper bin, recycling water for the garden… a daily shower time reduction from 9 to 8 minutes saves 2900 l./p/year!
This reduction is based purely on changing habits! In the EU buildings are responsible for 40% of energy consumption of CO2 emissions. That’s why we need to focus on nZEB .
Flow and temperature of hot and cold water can be sent to the cloud for statistical treatment.
This enables finding behavior patterns, some leaks, and fine tune water heaters according to demand rather than having them at a fixed temperature 24/7.
Designed to raise awareness of water use.
