Smart Buildings & Smart Energy: the Integration Challenge

Last week, twenty of us gathered in DC for a two-day charrette on the standards needed to apply BIM to the problems of dynamic energy management. The work-shop, entitled “Smart Buildings, Smart Energy”, was put on by the Corps of Engineers Research Lab (CERL) at the National Insitute for Building Science (NIBS). The meeting was a fascinating, and occasionally heated conversation that brought together academic and government researchers, building system practitioners from industry leading companies, and participants in standards committees from ASHRAE to OASIS. It was a fascinating meeting, filled with bright, deeply focused individuals who as a group had not yet recognized the profound changes in their goals required by smart energy...

Energy Privacy

p> Energy Privacy was the hottest topic of Grid-Interop in Denver. Perhaps it was the Google Energy demos, which show people discussing each little recurring burst of energy use, whether refrigerator or Jacuzzi, that alerted the public to the issues. Perhaps it was when people read the UCAIug plan for OpenADE, which lists a "Law Enforcement Interface" for energy use as a higher priority than sharing information with the building occupants. Perhaps it was a late-night comedian commenting slyly that at least battery-operated devices could not be tracked, yet. Perhaps it was heightened awareness flowing over from health care debate. However it happened, privacy issues and privacy concerns became front and center at the Grid-Interop and the SGIP.

A Microgrid of One

The target of smart grid communications, particularly in collaborative energy space, should always be the microgrid. Some microgrids may contain a single home, or commercial building, or and industrial site—those are irrelevant details. Microgrids have a number of systems inside them that must work within the economic environment of that microgrid—and I am thinking of old economics, before the distinction of economics and ecosystem arose. Some microgrids may have a single entity inside, say a legacy BAS (Building Automation System), but the unitary microgrid is merely an artifact of...

Small standards for small things

We were discussing standards upon which to build standards today. Before systems can communicate, there is a lot of work building the platform they communicate from. So much of the small work that will be needed for the internet of things is based upon constrained communications between resource-constrained devices. I found myself spitting out acronyms right and left - a veritable techno-glossolalia
