This February 2020 report by GT – Institut für Gebäudetechnologie GmbH (The Institute for Building Technology) describes how building automation systems have evolved as more sensor data are factored into control algorithms. Value-added services using sensors to enhance environmental control, lighting, elevator maintenance, etc. are discussed. Eleven wireless communication protocols to support sensors for these applications are evaluated and scored.  The top two were EnOcean (for commercial buildings and professional installation in homes) and Z-Wave (for do-it-yourself home automation).
Key words: intelligent building, IOT, large building controls/automation, lifts/elevators, communications, connected home, lighting systems/controls
