A Green Button software developer kit user guide is now available courtesy of the National Institue of Standards and Technology.
The guide includes information on Green Button data composition, how to present data using extensible markup language and sample source code, including finished examples.
The Green Button initiative, launched in September 2011, gives customers access to energy usage data through a branded green button on participating electric utility websites. Since its inception, more than 30 utility companies have committed to providing customer data via XML downloads.
The Green Button SDK was released in October 2011 and has sparked more than 50 energy-focused web and mobile applications.
Green Button was modeled after the Blue Button, developed by the Department of Veterans Affairs, that allows users to freely access and share their personal health information.
