Andrei Litiu (ed.), Bonnie Brook, Stefano Corgnati, Simona D'Oca, Valentina Fabi, Markus Keel, Hans Kranz, Jarek Kurnitski, Peter Schoenenberger, Roland Ullmann

This guidebook aims to provide an overview on the different aspects of building automation, controls and technical building management and steer the direction to further in depth information on specific issues, thus increasing the readers' awareness and knowledge on this essential piece of the construction sector puzzle. It avoids reinventing the wheel and rather focuses on collecting and complementing existing resources on this topic in the attempt of offering a one-stop guide. The readers will benefit of several compiled lists of standards and other relevant publications and as well a thorough terminology specific for building automation, controls and technical building management.

Final voting on prEN 16798-1: narrow disapproval

As we all can read from the new issue of REHVA Journal (1/2017), 29 EPB EN-standards of the total 31 have been approved. These standards passed the Formal Vote last week of January 2017 and will soon be published. FprEN 16798-3 is still on voting until early April 2017, and the Committee Vote on Technical Reports prCEN/TR 16798-2 and -4 will close in early March. Formal Vote on FprEN 16798-1 Energy performance of buildings. Part 1: Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics closed on 9 February. In the weighted vote, 69% of the cast votes were positive, but 71% would have been needed to have the standard approved.
The CEN regulations give several options to proceed after a negative result. The Technical Committee in charge, in this case CEN/TC 156, will decide (by taking a decision) on one of several options, including:

  • To submit a modified version of the FprEN to a second Formal Vote;
  • To submit a modified version of the FprEN to a UAP (Unique Acceptance Procedure);
  • To transfer the work to ISO within the framework of the Vienna Agreement, if appropriate.


In this case, the ISO option is interesting, because the technically nearly identical ISO 17772-1 has been approved in ISO voting, giving a possibility to adopt it as an EN ISO standard, with or without modifications. However, in any case the decision is now up to CEN/TC 156, who will have the next scheduled meeting in early May.
