Several web surveys have been performed before and during project DAIAD's Trial A, collecting critical information about the participants and their households, their satisfaction and observations regarding the DAIAD system, as well as their views regarding the real-world deployment and pricing of the system. The responses from each survey are linked to a specific household.

To protect user privacy, the datasets have been anonymized by replacing the user’s account with a unique surrogate key. In total, there are four survey datasets:

Pre-Trial: The Pre-Trial survey was sent by email to selected participants that have completed the Recruitment survey. Its purpose was to (a) confirm the contact details of the participant, and (b) collect additional information about the household and its water consumption behavior. The survey questions are provided in the project's Report Deliverables D7.1 (http://daiad.eu/wp-content/uploads/2017/11/D7.1_Trial_A_Report.pdf).

Satisfaction: The Satisfaction survey was sent by email to Trial A participants twice during the project's Trial; first as a standalone survey (M32), and a second time integrated into the Post-Trial survey (see below, M38). Its purpose was to assess the satisfaction of all participants regarding the DAIAD system and its various aspects. The survey questions are provided in the project's Report Deliverables D7.1 (http://daiad.eu/wp-content/uploads/2017/11/D7.1_Trial_A_Report.pdf).

Pricing: The Pricing survey was distributed in M38 by email to all project's Trial participants, as well as other AMAEM consumers (participants were invited to share the survey with their friends and family). The survey included a series of questions exploring the potential pricing points and purchase options for the DAIAD system (e.g., one-time, fee integrated in the periodic utility bill), which was communicated as a request for interest to purchase the DAIAD system. The survey questions are provided in Annex 3 – Pricing Survey of the project's Report Deliverables D7.3 (http://daiad.eu/wp-content/uploads/2017/11/D7.3_Trials_Evaluation_v1.0.pdf).

Post-Trial: The Post-trial survey was distributed in M38 by email to all Trial participants, along with a notification regarding the official end of the Trials. The survey included several questions examining the usability of the system, the changes in attitudes and behaviors regarding conservation of our participants, and their overall satisfaction from the DAIAD system. The survey questions are provided in Annex 4 - Post-Trial Survey of the project's Report Deliverables D7.3 (http://daiad.eu/wp-content/uploads/2017/11/D7.3_Trials_Evaluation_v1.0.pdf).
