The GridOptimal Buildings Initiative needed a rigorous, quantitative foundation for understanding how much grid flexibility building-side measures could actually deliver. We modeled nine load modification strategies across three U.S. climates and two building performance levels, individually and in packages, capturing both peak demand reduction and load shift potential. 

The findings gave NBI and its utility coalition partners the evidence base to define grid-interactive building metrics, and gave manufacturers of demand-flexible products a credible, independent study showing the scale of opportunity their technologies are part of.
