This bi-annual summary provides an overview and key information from the activities ran by the streamSAVE dialogue groups between January and June 2021, discussing methodologies and issues related to the calculation of energy savings from five Priority Actions: BACS (Building Automation & Control Systems), Public Lighting, Electric Vehicles, Heat Recovery, and Refrigeration systems.

Overall, 139 single participants from 29 countries took part in at least one of the activities organised in the first semester 2021.

The summary’s take away’s are:

• Developing simplified calculation methodology first requires defining well its scope.
• Ecodesign regulations and EPBD provisions are important to take into account in the methodology, especially for defining the baseline.
• Availability of indicative values varies according to the action types.
• Reliable data on costs in addition to the baseline are difficult to identify or access.
• Collecting data specific to each savings projects increase the reliability of energy savings. But simplified methods with indicative values are useful to monitor schemes dealing with large number of projects/actions.

Please note that a next series of meetings, including external speakers, will be organised in October-November 2021: check the streamSAVE platform to get the dates and agendas!
