We present the EarlyOff concept, whereby home heating can be predictively turned off in advance of occupants\u2019 departure, using this inertia to keep the house warm while saving energy. We use a previously gathered data set of real-time heating, gas, and occupancy readings from five houses and conduct a data-driven analysis of potential energy savings. Using an \u201coracle\u201d predicting actual departure events, we show an upper bound savings of 4\u201312% of the gas used over the whole study period by applying EarlyOff. Using a real predictor which makes use of historical occupancy probabilities, we show savings of 1\u20138% of gas use.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Home heating systems often have a significant thermal inertia, as homes stay warm after the heating is turned off for significant periods of time.
