From Jim Sinopoli, Automated Building.
The electrical utility grid that Thomas Edison initiated over 100 years ago is long overdue for an overhaul. It will be a 180 degree change in the utility business model, going from selling more and more energy to consumers to putting everyone on a healthy energy “diet”. The entire concept of the utility grid, buildings, vehicles, energy sources and energy storage all communicating with one another to enable the efficient use of energy is ambitious and breathtaking. It will be the details of implementation that will determine its success.
Much of the Smart Grid is obviously focused on utility grids not necessarily buildings. However, some of the characteristics of the Smart Grid effort addresses the integration of distributed energy resources, demand response, demand-side resources, ‘‘smart’’ appliances and consumer devices, plug-in electric and hybrid electric vehicles, thermal-storage air conditioning, and timely information and control options for consumers. Intuitively we know that a smart grid without smart buildings would be a greatly diminished deployment and a very expensive lost opportunity.
The larger question is what are the attributes and characteristics of the connection between smart buildings and the smart grid? What are the applications? What is the communications interface? How will it be addressed technically? What could or will it mean for building owners and facility management? Buildings are being designed and upgraded to be energy efficient but that effort often is disconnected from the Smart Grid initiative- how do we get the two in sync? Let’s start with the possibilities of applications and then review the possible communications protocols.
