Technological advances in demand response and energy efficiency have increased the utility of residential and commercial buildings for owners and operators. Yet buildings still lack the capacity to adapt to both internal and external changes, such as occupant needs or grid stability concerns. Basic information about the energy portfolio of buildings is not readily available to owners and operators, leading to inefficiencies and lost opportunities within and beyond the building.
This report describes technologies and systems needed to transform buildings from the current state of siloed resources into transparent, reliable resources that participate in and benefit from an integrated “transactive energy” system. This transactive approach is described in more detail in the accompanying “Buildings-to-Grid Technical Opportunities: Introduction and Vision” report.
