From: Estimating the savings potential of occupancy-based heating strategies

The relative savings for two artificial households (one “new” and one “old”) depending on the duration of continuous absence. The average occupancy always is 75%. Since in any case the household is unoccupied for 25% of the time, the savings are at least 5% even for short periods of absence and better insulated new houses. For longer periods of absence, they converge towards a certain level around 18% – a limit imposed by the 10°C setback temperature and the fact that the building is occupied 75% of the time
