The Venergy Advanced Metering System app displays the real-time energy usage of an entire building or its subcomponents, such as individual rooms or circuits. Using data collected by the Cooper Controls Advanced Metering System, the app expresses consumption by electrical and non-electrical building loads such as lighting, HVAC, and photovoltaic systems in dollars or in carbon dioxide emissions. Information is updated every minute, and an archive of energy usage is also kept available. The app is available for the iPad, iPhone, and Sony Dash.
