Utility Digital Customer Engagement

The Green Button energy- and water-data-access standard enables electric, gas, and water utilities to offer customers access to their usage data and empower them to securely share those data with authorized third-party service providers that can help them further monitor and manage their energy or water consumption.

The Green Button standard ensures customer privacy and secure transmission of data; providing customers assurance and helping utilities and solution providers to meet regulatory requirements. Green Button solutions help utilities maximize investments in advanced metering infrastructure but do not require smart meters to be in place for utilities to provide standardized Green Button customer usage data.

Green Button data can be obtained from smart meters, interval meters, manual meters, or net meters and the standard allows the information to be reported in any interval the utility chooses: from 1 minute to 2 months.

  • Provides Customer Usage Data with
  • or without Smart Meters
  • Platform for Digitally Engaging with Customers
  • Ensures Utilities & Third Parties
  • Protect Customer Privacy
  • Cost-effective Deployment Models,
  • New Business Opportunities & Programs

Green Button has been instrumental in transforming the way London Hydro engages with our customers. London Hydro deploys Green Button data via cloud computing to enable our residential customers to access their usage data and shift high-peak usage, and for our commercial or institutional customers to manage building energy consumption across multiple facilities and campuses. Green Button is enabling us to offer new programs and services.

Energy Management for Buildings

Green Button—Revolutionizing Energy Management for Commercial Buildings

Green Button enables building owners and property managers to easily access and collect whole-building energy consumption, generation, and billing data in a common format across single or multiple buildings and utilities—effectively removing time-consuming, manual data collection, processing, and reporting barriers.

Green Button’s standardized format ensures data consistency and accuracy by eliminating manual entry and enables energy managers to link multiple-meter energy usage with location to identify individual buildings—streamlining energy reporting for multiple consumption points. Energy managers can readily access building consumption data and make adjustments faster, can securely share the data with solution providers for further analysis, and can more-easily report the data for portfolio management, compliance, or sustainability programs.

  • Standardized Data Access & Easy Collection Across Buildings & Utilities
  • Eliminates Manual Data Entry; Ensures Data Consistency & Accuracy
  • Data Sharing with Solution Providers & Databases
  • Streamlined Energy Reporting; Integration with Benchmarking Platforms
  • Tenant-Engagement Applications

Green Button removes the manual data-collection and -access barrier for Commercial and Industrial sector users. Building owners and property managers can easily retrieve utility-provided Green Button consumption data in a consistent format across multiple utilities and utility types, arming them with the information and solution-enabled insights to ensure those buildings perform efficiently. This saves time, costs, and the environment.

Smart Energy & Water Solutions

Worldwide Market for Smart Energy & Water Solution Providers

The global Green Button standard allows companies to provide smart energy and water conservation platforms and applications to inform customers about their energy and water use and to empower them to manage their use by leveraging the solution providers’ analysis, insights, recommendations, alerts, or reports.

Utility IT companies can leverage the “big data” generated by Green Button products and applications to provide more value for customers. Control vendors can add Green Button functionality directly to products to expand their market. Green Button does not replace existing tools; developers can build a Green Button ‘connector’ to ensure their platform is ready for Green Button certification.

Industries, such as commercial and industrial buildings, heating and cooling, solar, real estate, and the Internet of Things (IoT), are leveraging Green Button data to enable smarter home and building energy management, support solar installation and monitoring, gauge home retrofits for energy efficiency, and to inform on where improvements such as new appliances, LED lighting, or insulation can be made.

Energyworx delivers insights and business value to energy system operators, retailers, and prosumers. For facility managers, the Energyworx platform monitors and correlates relevant datasources to help manage multiple locations by setting usage thresholds, benchmarking accounts and identifying opportunities to save. Energyworx leverages Green Button to obtain standardized energy consumption data, eliminating the need to support various utility protocols and streamlines the customer authorization process, so our applications can securely access the data.

Utility Data for Solar

Green Button—Unlocking Utility Data for the Solar Market

Green Button is an open-data standard designed to unlock utility interval and billing data—making them easy to retrieve and seamless to import into software applications. The proliferation of the Green Button data standard among utilities saves solar and energy software applications from having to support customized data formats. It enables them to quickly and securely obtain high-resolution, interval meter data; assures data integrity; and allows a highly accurate and detailed level of analysis.

Utilizing Green Button data, consumers and companies can precisely determine the benefit levels of installing solar by assessing the optimum system size, quantifying the financial savings of a potential system, analyzing existing installations to determine if time-of-use programs could be of value, or monitoring installations for on-going system performance and energy-storage efficacy.

Utility-provided Green Button customer usage data are highly sought-after by solar and solar software companies as it enables solar installers, financiers, and energy service companies to evaluate projects and savings faster and with more accuracy. Public-purpose programs, including demand response and energy efficiency programs, also benefit.
