[en] In the frame of two successive IEA-ECBCS annexes, the « CA-MET » building in Namur
was the object of commissioning and re-commissioning activities.
First, during the construction of the building and installation of the HVAC plant, a systematic
survey of the work was carried out in the frame of IEA Annex 34 (“Fault Detection”).
Therefore, attention was paid to a specific part of the plant (a typical Air handling Unit) and a
number of testing and verifications were performed, as a complement to the normal and ongoing
commissioning activities:
- testing and balancing of air and water networks
- air flowrate measurements
- water flowrate measurements
- control system analysis
The most important faults identified in this part of the project were classified according to the
IEA 34 template and, for each of these faults, the possibility of developing an automatic fault
detection method was analysed. The paper will report on the most relevant problems and
present the automatic fault detection method proposed. In a second step, which occurred
during in the early stages of the operational phase of the building, a further verification of
specific subsystems was carried out, as part of a re-commissioning activity. This work is
being realized in the frame of IEA Annex 40 and ends up with a proposal of systematic
verification procedure to be applied, as a first example, to a VAV system. This procedure
follows a hierarchical approach (bottom-up), starting with the local VAV loop, going through
the AHU and ending with the chilled water production equipment.
The paper reports on the application of the procedure to the selected building and will be
based upon experimental results obtained during target monitoring campaigns.
