Controls are the big topic of conversation at the moment. Light sources are only half the story because everyone knows the most efficient light source is one that’s turned off.
The rise of controls has come hand in hand with the rise of LEDs, which can be dimmed and can send and receive data. Improvements in user interfaces, and the ubiquity of smartphones and tablets, are also helping. And with the rise of wireless controls and power-line communication.
We can add controls to an existing office.
