This ASHB White Paper describes the fundamentals of Power over Ethernet (PoE), with explanations on the technology’s current state and the applicable codes and standards. PoE devices typically support sensors at every end point, and a denser sensor network enables more special customization of indoor environment conditions. It is also conceptually straightforward to make building data available to building occupants through mobile devices, and to enable their input to control decisions. These advantages promise to deliver behavioral and organizational productivity benefits based on occupant well-being.
Key words: Power over Ethernet (PoE), certification, licensing, powered devices
