BIOLOGY BEHIND DIGITIZATION BlueSky features a state-of-the-art network connected lighting system that addressed the typical lighting needs of the project. The lighting system is managed by centrally located software that is continuously fed data from the array of sensors in the building (Figure 7). The system utilizes PoE gateways connected to a PoE network switch to transmit IP-PoE power and commu- nication to a variety of operational technology (OT) devices, such as LED lighting fixtures, sensors, motorized shades, and relay/actuators. Lighting over IP, being ubiquitous in the building, automatically means the supporting network infrastruc- ture is already available throughout the floorspace. This allowed GP to deploy a variety of sensors on this IoT network. The project utilizes sensors that detect occu- pancy, vacancy, ambient light levels, lighting fixture power readouts, temperature and humidity from the different types of spaces (e.g., open office, conference rooms, breakouts, hallways). The sensors are in some cases embedded into the fixtures utilizing the Category cabling already used for the light fixtures and do not need to be wired or installed individually (Figure 8). Standalone sensors (outside of the lighting fixture) utilize wireless communication and energy harvesting and do not require any point-to-point power and communications cabling for these units. This additional network infrastructure was blended beautifully into the environment to appear non-intrusive while providing wide scale coverage of different areas in the building.
