INCREASE AWARENESS - RESULTS

• Pre and post intervention surveys undertaken at pilots to measure water

conservation behaviour;

• Pencil and paper questionnaires developed based on Norm Activation

Model (NAM; Schwartz, 1977) to explain altruistic pro environmental

behaviour;

• NAM looks at problem awareness (PA), ascription of responsibility (AR) and

outcome efficacy (OE) and how these relate to personal norms and

behaviour;

• Responses measured on 5 point scale where respondents chose a

response from strongly disagree (1) to strongly disagree (5) to a statement;

• Also measured – Personal Norms, Existing Behaviour, Intention to

Participate in promotion


INCREASE AWARENESS - RESULTS• Example of question to measure PA (1 of 3 Relating)

• Example of question to measure OE (1 of 5 Relating)

• Example of question to measure AR (1 of 4 Relating)

Flow Signature Application - Eng Building Showers – 15-20 showers per day approx. Average shower time is 5.8 minutes with a min and max of 1.5 - 15 minutes respectively. Average shower uses 200 litres with a min and max usage of 50 and 660 litres respectively.

Coláiste na Coiribe – Faults Identified Exceedance of Baseline/Unexpected Flow



• Significant usage identified on MWS (WM001) at approximately 15 m3/day (0.64m3/hr) - Continuous Flow

• Treating the water mains as a dendogram, each water main meter was investigated using a top-down hierarchal rule-based approach to identify the continuous flow signature.

• Continuous flows signature of Fault 1 was detected in the rainwater harvesting top-up line.

• Greywater tank supply to the building was found to be continuous during this period. Suspected to be a leak/faulty toilet cistern.

• Fault was reported to management in mid-March and was resolved on the 31st March.

• Fault coincided with a dry period resulting in the use of costed mains water as opposed harvested rainwater (239.24m3) .


LINATE-CONCLUSIONS

CONCLUSION COMMENT

Waternomics Information Platform Very Effective

Increase awareness among the airport managers and staff of normal usage -usage enabled identification of potential problems

Managers are interested in the Waternomics Information Platform

Interest in maintaining the platform for the Linate airport

At Linate interactions with Public Dashboard touch screen displays was very successful

More than 2000 users attracted. Personal water footprint calculated and feedback released

Great interest in Fault detection and the possibility to perform hydraulic simulation in a easy way

Staff at Linate acknowledge that useful for detecting faults at an early stage saving water and money


THERMI - CONCLUSIONS

CONCLUSION COMMENT

Increase in awareness confirmed by end users

The apps helped in understanding their water consumption

Users started thinking changing specific behaviours

In some cases users reported that it affected some of their decisions (especially the choice between washing dishes in the dishwasher or by hand)

Users became familiar with different water usages and their effect (e.g. water footprint)

Although challenged that we are looking only at water and does not include other environmental dimensions such as energy

Relative peace of mind for faults If measurement was in the mains supply it would be even better

Increased interest in adopting more smart home technologies

Especially for power consumption which is more expensive

In busy households water is not a high priority

Water is inexpensive and therefore not high on the list that affect the budget of a household


GALWAY PILOTS - CONCLUSIONS

CONCLUSION COMMENT

High Profile Display of Current Water Usage Number Very Effective

Creating significant discussion andcommentary from staff and students are aware of scale of volume

Managers are interested in concept and outputs of platform but cannot prioritise above emergency issues

Ensure that access to dashboard andinformation is as easy as possible –desktop icon/ weekly update

At NUIG and Coláiste na Coiribe, identification of faults very successful

Faults that would otherwise remain hidden are now being identified, limitations on maintenance budgets is issue

Consider water usage as Operation or System controlled and User controlled

In a public building behavioural change in staff and students will be overshadowed masked by system controlled consumption

Water awareness baselines are high and post intervention results show increase only in junior cycle students

May be difficult to increase awarenessresult from high baseline also in public building motivation for change is less clear


FINAL REMARKS

• Operational alert system in place for water retention

exceedance in potable water network NUIG

• Public dashboard to be maintained in NUIG Pilot and

developed as part of water/energy studies

• Significant faults identified in CnaC Pilot (3) and Engineering

Building Pilot (2)

• Extension of piloted systems from Linate Airport to Malpensa

airport

• Flow signature methodology developed & applied

• Some gains in awareness with secondary school students
