Essentials & Considerations of a Grid Interactive efficient Building (GEB)
A definition from a DOE 2019 report (see link below) defines GEB as an energy efficient building with smart technologies characterized by the active use of #DERs to optimize energy use for grid services, occupant needs and preferences, and cost reductions in a continuous and integrated way.

Taking a closer look at these definitions and characteristics. It’s clear a GEB needs to have conducted some level of efficiency measures, controllable loads, some form of #DG and or #energystorage, along with sensing, communications and software algorithms that have a some connectivity to the grid, that can manage and dispatch all the controllable elements in some timely and optimal manner.
With this in mind it brings about a few questions for deeper consideration and identification of potential gaps in the industry today. Heres a laundry list of topics I plan to delve deeper into over the next few weeks:
- Hierarchical optimization and control layers
- Aggregation of building and DER portfolios
- Offsite community solar and storage
- Grid to building interface
- Optimization potential conflicts and objective functions
- Value stacking, monetization and cash flows
- Bulk grid to local grid coordination
- Grid reliance on buildings and DER - Communications and cyber security
