A data center or IT room uniquely alters the requirements of a building management system (BMS). This is primarily because of the criticality of IT and its dependence on facility infrastructure. IT’s reliance on power and cooling systems makes a BMS an important part of a larger data center infrastructure management (DCIM) solution that brings together Facilities and IT. The cooperation and information sharing better ensures uninterrupted and efficient operation....More
A lot of leading building automations systems (BAS) are touted as being open. But what does that really mean? And does being open mean that building owners and operators are getting the most out of their BAS investments?
During this webinar, Johnson Controls BAS experts will examine the definition of openness and advise on what to look for from a BAS provider when secure interoperability and ease of integration is paramount.
