The second meeting of the Dialogue Groups on Feedback and tailored advice for behaviour changes and Small-scale RES for heating (including Domestic Hot Water) was held on Tuesday 15 November 2022.

You can find attached to this post the agenda, presentation files and minutes.

The meeting provided an update with complements about the calculation methodologies for both Priority Actions. Then guest presentations shared experience from Greece and the US:

- Example of the calculation methods for heat pumps used in Greece, by Christos Tourkolias (CRES, Greece)

- US experience with measuring energy savings from behavioural programmes, by Adam Thomas, Principal Consultant at ADM Associates

Key points highlighted in the presentations and discussions:

About small-scale RES for heating (with a focus on heat pumps in this meeting):

- Importance of the availability of national indicative values.

- Need to later consider cooling in the methodology.

- Importance of simplifying the monitoring data collection for bottom up measures.

About behaviour changes:

- There is a difference in calculating the behavioural measures’ savings depending on whether they do or do not include tailored feedback.

- Behavioural programs in the US consistently provide measurable savings, and are now very important for residential savings.

- The evaluation of the behavioural savings using RCTs pays off to the utilities, even if the price is high.

- There is a decline in savings when messages discontinue
