Reducing Plug-Load Electricity Footprint of Residential Buildings through Low-Cost, Non-Intrusive Sub-Metering and Personalized Feedback Technology

Columbia University, with partners Lucid, Siemens, and Microsoft, has developed a technology that encourages occupants to change their electricity use by reducing their load or shifting usage to non-peak hours. By utilizing a human-in-the-loop approach and occupant feedback strategies, this sub-metering and feedback technology can reduce residential energy use by at least 30%.
