Most houses have vents that open and close manually without any central control. Cities across the United States recommend the use of such vents in an effort to save energy. In most cases, household occupants do not use the entire house at the same time; the tendency is to use certain rooms for long periods of time. For example, the living room and dining room may be used heavily, while the kitchen is used at certain hours of the day. To cool or heat a room, the vent system must work to cool or heat the entire house. A house can save energy if the vents of unused rooms are closed; this will push the hot or cold air to where it is needed most and will reduce the load on the conditioning system.
