Building To Grid — AKA B2G

When it comes to the Smart Grid, are you prepared? Consider two design strategies to connect buildings to the available benefits.
By Paul Ehrlich, P.E.
No Comments
You’ve heard a lot of talk about the deployment of the Smart Grid. Most of the initial smart grid deployments are focused on the de-ployment of smart meters that enable utilities to gather usage information in near real time — or what they call Automated Meter Infrastructure (AMI).
