Why are there no specialities such as BMS, BEMS, Tridium, Niagara? Am I searching in the wrong location or is BAYT being deliberately obtuse?

I know the Middle East has plenty of BMS, BEMS, Tridium / Niagara AX and plenty of other equipment installed in their buildings. So why the lack of specialities related to BEMS, BMS in BAYT? Perhaps I am looking in the wrong location on the BAYT website or are they deliberately reducing the number of specialities and why ?
