The Meeting 2 of the Dialogue Group on BACS (Building Automation & Control Systems) was held on Tuesday 18 May 2021.

You can find attached to this post the agenda and presentation file of this meeting, as well as the minutes (restricted to registered users).

 

This meeting presented and discussed the calculation methodology developed by streamSAVE for energy savings from BACS. Key points highlighted in the discussions:

  • Importance of the new provisions on BACS included in the Articles 14 and 15 of the EPBD, especially for non-residential buildings from 2025.
  • Importance of ensuring a proper commissioning and maintenance.
  • Diversity in Member States’ practices as regards requirements for BACS and calculation approaches (cf. detailed or simplified)
  • Little information about BACS factors and existing BACS situation is available. Support and resources, especially about BACS factors and how to set a baseline to calculate energy savings from BACS, would be welcome by practitioners.
  • Reporting related to the inspection of heating and Air Conditioning systems (as required by Articles 14 and 15 of the EPBD) and monitoring of incentive schemes can be useful data sources.
  • Databases of Energy Performance Certificates (EPCs) can also be useful sources about unitary energy consumption of buildings (but data to consider with caution, as EPCs might sometimes overestimate energy consumption)
  • BACS might develop the availability of measured/metered data at project/building level. However, it remains difficult to collect measured/metered data for the monitoring of a policy or programme with a large number of actions. Therefore, simplified approaches can be useful at programme/policy level.
