18. INTERIOR-WALLThe INTERIOR-WALL instruction is used to specify the slze, construction,and adjacent space for an interior wall, ceiling, or interior floor. TheINTERIOR-WALL wi 11 be considered as a heat transfer' surface by the LOADS andSYSTEMS programs. Each INTERIOR-WALL instruction applies to the SPACE instructionpreceding it and describes one of the interior walls, ceilings, orinterior floors of that space.U-nameINTERIOR-WALLLIKEAREAHEIGHTWIDTHLOCATIONCONSTRUCTI ONmay be specified.This command word tells LOADS that the data to followspecify an interior wall, ceiling, or interior floor.may be used to copy data from a previously U-namedINTERIOR-WALL instruction.is the surface area of the interior wall, ceiling, orin ter ior floor.is the dimension of the interior wall parallel to the Y axisin the surface coordinate system (see Sec.

A U-value may be used to represent thecombined conductive and convective effects of the boundarybetween two spaces. For boundaries that are free air, theeffective U-value must be approximated: U ~ 0.01578 *Volume/(Area * Time). Volume is the mean volume of the twospaces between which heat is transferred; Area is the areaII I. 113 (Revised 5/81)
