ecoMOD Home Energy and Environmental Monitoring System

University of Virginia, 2008 - $15,000

EcoMOD is an ongoing green building project at the University of Virginia in which architecture and engineering students construct affordable, modular homes that use 30-50% less energy than similar houses. They’ve built five houses so far, funded by a variety of non-profits, corporations and the EPA. The first house, ecoMOD1, has an extensive monitoring system in place to gather data on energy and water usage. While the system works well, it’s far too expensive to be a commercial energy-monitoring product and hasn’t been replicated in the other ecoMOD homes.

The team is now developing a commercial version: a low-cost, freeware, wireless home energy monitoring system that provides real-time feedback on energy use (electricity consumption of major appliances, water consumption, indoor and outdoor temperature and humidity, and carbon dioxide emissions), has the capability to adjust thermostat and ventilation settings based on whether the residents are home, and enables peak load shedding of selected appliances based on price signals from the utility. It consists of microcontrollers ranged around the house, a base station, and a web interface.
