Reference Interoperability Procurement Language

Interoperability has important economic benefits, or to put it another way; lack of interoperability has negative economic consequences. Interoperability is the ability of two or more systems or components to exchange information and to use the information that has been exchanged.Systems composed of advanced devices and applications require an interchange process that necessitates well-defined interfaces for the transfer of information between components and to simplify the integration process. 

The focus of this work includes devices and systems in buildings, devices and systems on the grid with which devices and buildings might interact, and services to integrate them, including existing uses and future uses driven by distributed energy resource and smart device proliferation.
