• A standardized data format for energy usage information with download/automated transfer at direction of consumer
• Broadly supported by the Government, Utilities, Entrepreneurs, Third Parties
• Unleashes innovation resulting in energy efficiency apps and services never possible before

White House Inspired -‐ Industry Led
2011 – White House challenged industry to proac#vely engage consumers in the management of their energy usage. 2012 – Industry responded with commitment to provide access to usage through the Green Bu8on Standard 2013 – 30 Million (and growing) residen#al consumers have access to their energy usage informa#on

Example use case: solar PV proposal Courtesy of Ma8 Theall, Green Bu8on Presiden#al Innova#on Fellow (DOE)
“Solar companies are also eager for consumer data because understanding a homeowner's electricity use is key to the sales process.” – San Jose Mercury News
16,398 x 20yrs = 327,960 kWh @ 0.35 = $114,786 Based on Ma8’s Green
Bu8on Data: More than 2X Higher Than EsBmated!
PV quote based on state average annual electricity consumpBon (Green Bu8on
data not available yet)
Actuals/month 16398/12 = 1366.50 kWh/month $2,774.04/12 = $231.17/month
Es#mated 600 kWh/month $118/month

Administra#on Privacy Blueprint • Guides efforts to give users more
control over the use of their personal informa#on and help businesses maintain consumer trust.
• Recommends convening stakeholders to develop and implement enforceable privacy policies based on the Consumer Privacy Bill of Rights
• In the energy u#lity sector, the Federal Smart Grid Task Force (led by Dept. of Energy) is leading privacy efforts. – DOE Voluntary Code of Conduct

Consumer Privacy Seal • Third party access to consumer energy data enables a wide range
of benefits, but also raises legi#mate concerns • Responsible companies that provide exci#ng new products and
services such as home security, smart appliances, remote home management will generate posi#ve consumer interest and help advance consumer engagement with energy management, demand response and smart meters.
• It is essen#al that a flexible framework exists that ensures consumer privacy protec#ons are in place and that responsible businesses can responsibly access the data needed to serve consumers.
• Risk to u#li#es, consumers if inadequate process for obtaining consumer permission
• Risk to consumer engagement and innova#on if consent process is burdensome and ineffec#ve

Green Bu8on and OData OData provides a way to encapsulate domain specific informaBon within the Pubish/Subscribe pa8erns of Atom Publishing. • OData is a standardized protocol for crea#ng and consuming data APIs.
• OData builds on core protocols like HTTP and commonly accepted methodologies like REST.
Green Bu8on uses this approach to place Energy Usage InformaBon within Atom streams. • The Green Bu8on resources are contained within the Atom <content> tags
• Rela#onships between Green Bu8on resources are contained within the Atom <link> tags.
