The Meeting 3 of the Dialogue Groups on Heat Recovery and Refrigeration systems was held on Tuesday 19 October 2021.

 

You can find attached to this post the agenda, presentation file and minutes of this meeting.

 

This meeting presented and discussed the calculation methodologies developed by streamSAVE for energy savings from heat recovery and refrigeration systems. Key points highlighted in the discussions:

  • Heat recovery and refrigeration systems represent significant potentials of final energy savings.
  • The scope considered is very important when assessing final energy savings from heat recovery systems, hence the distinction between three main cases.
  • Projects in industry are sometimes complex and requiring to use specific data to calculate the savings. A standard method then helps to ensure that the calculations are done in line with the rules set in the scheme it is reported to.
  • For projects in industry, part of the data needed can often be collected from meters or other measurement devices already in place for other purposes (e.g., safety, optimisation). However, projects in industry might also deal with various processes and complex interactions, making the assessment of energy savings also complex.
  • Assessing the rebound effect mostly depends on the perspective you adopt (policy or project). Moreover, the notion of rebound effect in industry might not always be relevant, and be related in practice to productivity gains.
  • For refrigeration systems, the efficiency indicators to be documented by the manufacturers have evolved. Which might require to update the calculation methods used by Member States accordingly.
  • Indicative cost values about refrigeration systems can be found in the preparatory studies (impact assessments) in frame of the Ecodesign Directive. These values can be presented in absolute ranges to give an order of magnitude of the cost of a project, or in relative terms (cost per kW of capacity), as the capacity has a strong influence on cost.
  • The indicative cost values provide a general benchmark, but should not be used for a particular case.
  • A set of deemed savings can be used to provide a standardised way to monitor energy savings while reflecting variations according to key parameters that can easily be reported by stakeholders.
