Attics can also help control temperature in a house by providing a large mass of slowly moving air. Hot air rising from lower floors of a building often gets retained in the attic, further compounding their reputation as inhospitable environments. However, in recent years many attics have been insulated to help decrease heating costs since on average, uninsulated attics account for 15% of the total energy loss in a typical house.
Ventilation
Modern building codes require unoccupied attics to be ventilated to reduce the accumulation of heat and moisture that contribute to mold growth and decay of wood rafters and ceiling joists.
