Is there a need to scope BEMS and BACS in a more detailed way? Should the streamSAVE project make a distinction between BEMS on the one hand, and BACS on the other? Is it interesting to look into different building types and different building systems in the calculations for art. 3 EED? Or is it more useful to make a distinction between different building types and different building systems with regards to the calculations for art. 7 EED? We are looking forward to your questions and suggestions on scoping this broad category further.
