Certainly, increasing building electrification (BE) is a critical step toward decarbonization of the built environment. The specific steps to achieve BE are somewhat less certain. Replacing carbon-emitting fossil fuel appliances with clean electric sources is the easy answer, but as usual there are lots of complexities in making this happen in both commercial and residential buildings – new and existing. During the Smart Buildings Exchange (SBX) 2021 virtual conference, two technical sessions on grid-interactive efficient buildings (GEBs) highlighted the potential values of deploying dynamic two-way communication capacity in buildings to both the electric utility system and building owners and managers. This two-way communication can automate load shifting, shedding, and modulating and improve a utility’s capacity, resiliency, and cost. Building on the SBX 2021 conversations, this two-part Executive Forum discussion will link the efforts around BE to successful widespread deployment of GEBs.
