National Opportunity for Interoperability and Its Benefits for a Reliable, Robust, and Future Grid Realized Through Buildings   [open pdf - 889KB]

From the Preface: "The electric industry is actively evaluating different potential business models of distributed utilities where core principles can help focus the design of the future power grid. [...] Because about 74% of the electricity sold nationally by distribution utilities is used, or 'consumed,' by the residential and commercial buildings sectors, interoperability of end-use appliances, equipment, and devices is essential, or the attendant integration costs will prohibit access to the value and benefits that coordinated operations provide. Interoperability is an essential enabler for technology to scale, as it moves us away from today's state of highly customized integration. [...] This white paper discusses interoperability as it applies to buildings and building interactions with grids and other systems, its impact and opportunity for the grid and the economy, and policy ideas that support an interoperable future. We define interoperability as the ability to exchange actionable information between two or more systems and across and within organizational boundaries. Interoperability relies on the shared meaning of the exchanged information, with agreed-upon expectations and consequences for the response to the information exchange, which makes the interoperability problem about more than simple data exchange."
