I wrote an article for RealComm (corporate real estate organization) on control system cyber security and what it means to commercial buildings. The discussion goes beyond the traditional source of building control system cyber vulnerabilities - the building automation control system being directly connected to the Internet. I have provided two actual examples of physical damage to buildings, in this case data centers, from control system cyber incidents – Aurora and what can be considered a form of Stuxnet. The article can be found at https://www.realcomm.com/advisory/904/1/control-system-cybersecurity-and-what-it-means-to-buildings
