Hypothesis I would like to test one day - does the increase in calories (and therefore additional energy used to produce food) to heat your body offset the energy saved by reduced heating. Start by assuming person living alone. Then could take it a step further increase number of people and take into account the body heat of each person (people produce alot of heat + water)
