▁autom ation . ▁ ▁Building ▁control ▁systems ▁include ▁those ▁elect rical ▁and ▁mechanical ▁systems ▁that ▁operate ▁inside ▁a ▁building , ▁including ▁He ating ▁and ▁C ool ing ▁( H V AC ), ▁Security , ▁Power ▁Management , ▁and ▁Life / S af ety ▁Al ar ms ▁that ▁are ▁in ▁nearly ▁all ▁buildings ▁as ▁well ▁as ▁the ▁my ri ad ▁of ▁special ▁purpose ▁systems ▁that ▁may ▁be ▁tied ▁to ▁particular ▁buildings ▁such ▁as ▁A / V ▁Event ▁Management , ▁Theatre ▁Light ing , ▁Medical ▁Gas ▁Distribution , ▁F ume ▁H ood s , ▁and ▁many ▁others . ▁ ▁o B IX ▁is ▁a ▁web ▁services ▁interface ▁because ▁it ▁does ▁not ▁necessarily ▁allow ▁deep ▁interactions ▁with ▁the ▁underlying ▁control ▁systems . ▁This ▁interface ▁can ▁enable ▁communic ations ▁between ▁enter prise ▁applications ▁and ▁embedded ▁building ▁systems ▁as ▁well ▁as ▁between ▁two ▁embedded ▁building ▁systems . ▁Fac ilities ▁and ▁their ▁operations ▁to ▁be ▁managed ▁as ▁full ▁participants ▁in ▁knowledge - based ▁business es . ▁ ▁o B IX ▁is ▁being ▁developed ▁within ▁O AS IS , ▁the ▁Organ ization ▁for ▁the ▁Ad van cement ▁of ▁Struct ured ▁Information ▁Stand ards . ▁Version ▁ 1 . 0 ▁was ▁completed ▁as ▁a ▁committee ▁standard ▁in ▁December ▁ 2 0 0 6 . ▁ ▁Background ▁▁ ▁Pres ently ▁most ▁mechanical ▁and ▁elect rical ▁systems ▁are ▁provided ▁with ▁embedded ▁digital ▁controls ▁( DD C ). ▁Most ▁of ▁these ▁devices ▁are ▁low ▁cost ▁and ▁not ▁enabled ▁for ▁TCP / IP . ▁They ▁are ▁installed ▁with ▁dedicated ▁communic ations ▁w iring . ▁Lar
