Building automation and control (BAC) systems can manage everything in the built environment from light and temperature to air and water to security and servicing. Yet traditional hard- wired BAC systems are costly to install, challenging to extend, and inflexible when it comes to adding new functions that match evolving building use. Is there a better way to manage functional spaces?

• Users and owners of built spaces now demand a higher level of control, with richer data and improved BAC efficiency.

• As BAC systems are upgraded, cost and system flexibility are key concerns.

• A new generation of low-power wide-area networking technologies offer a light touch total solution to the BAC challenge.
