Wal-Mart, Schneider Electric Test the Grid-to-Building Energy Connection

May 28, 2014 by Jeff St. John

Modern buildings contain a lot of devices -- fans, pumps, lights, motors -- that can slow down or speed up, dim or brighten, or otherwise alter their electricity consumption on the fly. Utilities and grid operators are eager for fast-responding energy assets that can shave power usage.[read more]

Libraries Need to 'Read Up' on Energy Efficiency

May 23, 2014 by Wego Wise

Libraries and Energy Efficiency

We have the privilege of spending a LOT of time in energy data. Beyond the 20,000 multifamily buildings in our database, we have spent much of the last year adding non-residential buildings. This week we were digging into libraries, and decided we might as well share what we found.[read more]
