HMS: HOME ENERGY MANAGEMENT SYSTEM Progress Energy Senior Design Symposium, April 8, 2011 Sponsored by Progress Energy Senior Advisor: Dr. Samuel Richie Team Members: Ryan Jones, Zineb Heater, Dennis Kilgore

Problems Power bills only give consumers a look at Monthly power usage Power usage for the entire house Standby Power Entertainment systems consume power when off, cable box, gaming system, almost every other modern device Research in leading G8 countries shows that Standby power consumes 8 to 12 percent of a home power bill* France – 7% US – 10% Japan – 12% *The Economist, 2006

Empty House You aren’t using most of your house 50% of the time 45+ hours at work (8 hour work day, 1 hour break time) 45+ hours of sleep (7 hours per night) 90+ hours of the 168 hours in a week What if you could program your house to ‘shut down’ when you don’t need it? Billion kWh used in houses in the US 78 Million households in the US using an average of 910kWh per month 7 Billion kWh wasted by standby power 800 Million dollars wasted by consumers per month

What does it do? Measures the power being consumed in real time by an appliance plugged into an outlet Wirelessly sends that information to a control touchscreen Allows manual or automatic shutdown of an outlet from the control screen Allows consumers to better change power consumption habits by giving a visual incentive

How you use it All that a consumer has to worry about is installing the touch screen Plug our box into an outlet, then plug what ever you want to measure into our box The data will appear on the touch screen within seconds That is all you have to do.

Information Display View historic power usage as a graph to see when the appliance is using the most power in a day or week.
