Addresses opportunities to deploy integrated building automation systems and bringing the "Internet of Things" into the realm of facilities management. "Systems that control such building functions as heating, ventilation and air conditioning (HVAC); security; refrigeration; and lighting have historically operated as standalone entities. They have also, for the most part, occupied a proprietary niche, separated from mainstream IT systems and standards. This isolation, however, is beginning to give way to a more cohesive environment. Integrators and resellers focusing on building automation now look to bridge the gaps among their customers' systems."
