If you’re concerned about your building’s energy use, and particularly if you want to lower it, you’ll need to pay attention to its systems. Not just when something breaks, but all the time.

Darren Johnson, account manager at Bright Power, an energy management company, explains how the smart technology works and how buildings can take advantage of it. Darren Johnson is interviewed by Carol Ott for Habitat Magazine.
