Analysis of lifestyle effects on residential energy use

Technical Report ·
OSTI ID:6071200
An analysis of a large data set was performed to identify lifestyle trends or relationships that should be accounted for in retrofit performance research. Occupant-controlled thermostat settings, as reflected by indoor temperature or heating and air conditioning energy use, were examined with respect to outdoor temperature, heating system type, family size, house size, and house type. Hot water energy use was similarly examined. Several trends associated with these variables were idetified: homes with central thermostats are more likely to use nighttime temperature setback during the winter than those with individual room controllers; outdoor temperature has a stronger effect on thermostat management during the winter than during the summer; house type affects air conditioner energy use and may shift the winter/summer balance of savings for some retrofit measures; and hot water use varies seasonally, and the variation is most noticeable during the fall months.
