Connectivity enhances a building’s responsiveness to internal changes as well as resilience against external challenges. A few years ago, the only interaction between a building and its wider environment came via utility meters. Today, high performing buildings are expected to respond to a myriad of stimuli from the internal environment (changes in lighting, temperature, humidity, CO2, ventilation and occupancy levels), requirements of Information Technology (structured and unstructured data from the cloud and on premise computers) and demands from Operational Technology (signals from elevators, security apparatus and heating and cooling systems). The building also needs to be responsive to weather events and surrounding buildings in the campus as well as to signals from the electric grid (e.g. demand-response events), the micro-grid (storage and renewable energy generation) and electric vehicles.
