Description of Athens Case Study

Aiming to meet the challenges of the project and deliver smarter, innovative analytics, NTUA will lead the design and implementation of a small scale case study in the City of Athens (Greece). The pilot program will monitor water and energy consumption at 20 households using high-resolution metering devices, aiming to gather additional data and valuable information on water consumption patterns. The high-resolution data will offer the opportunity to develop even more advanced applications, with a focus on the water-energy nexus. The small number of participants allows a detailed monitoring and study of customers’ behaviour on water related issues through qualitative surveys, giving the project a more experimental character.

It is envisaged that the pilot will act as an online laboratory in which the developer side is in close connection with the customer side. The participants are selected from a pool of volunteers and form a representative sample that covers a wide range of customer profiles with different socio-demographic characteristics. It is expected that the pilot case study will start in early May 2014 and will be part of the on-line testing and validation of the iWIDGET system, following the time schedule of the project. All the necessary equipment and devices will be provided and installed by UPL.


Athens Pilot “Identity”

 Case Study Profile

  • Combined real-time monitoring of water and energy consumption at 20 households
  • High-resolution data (lower than 15 min) and frequent transmission (more than 2 times a day) offering the “real-time sense” to end-users  
  • Appropriate selection of participants from an initial pool of 30 volunteers that covers a wide range of consumer profiles
  • Selection based to prior NTUA qualitative research on water-related issues in the city of Athens in the framework of iWIDGET


Challenges and Benefits for iWIDGET

  • Combined analysis of water and energy consumption patterns – efficient development of tools and widgets
  • Further analysis of specific behaviours via frequent qualitative surveys
  • Live experiment – continuous two-way communication between developers and volunteers (simultaneous calibration and validation of the system)


Stakeholder Workshop in Athens

Following the stakeholder workshops in Portugal and the UK, a stakeholder workshop took place in Athens in March 2014. The majority of volunteers were able to attend and get additional insights to the project and its objectives. Volunteers had also the chance to discuss their views on the opportunities and barriers associated with the use of smart meters in urban water services. The workshop has contributed to increase our understanding on what different stakeholders desire in an integrated smart meter technology system for water management and their priorities for smart meters for water.
