THICKNESSRu 1 es:1.2.3.4.5.6.7.The number of elements in the list is the number of layersin the construction. For an exterior wall, the sequence ofelements in the list is the sequence of the material layersin the exterior wall, starting with the exterior layer andending with the interior layer. For an interior wall, thesequence of elements in the list is the sequence of materiallayers in the interior-wall, starting with the layer on theopposite side of the wall and ending with the layer on thenear side of the wall. Reversing this sequence can notablyaffect the thermal performance of a wall.identifies a list that gives the thickness; in feet, foreach material in the construction. The list has the samenumber and order of elements as the immediately precedingMATERIAL instruction. If no thickness is specified, it willbe taken from the MATERIAL instruction.The outside film coefficient of an exterior wall or roofshould not be specified as a layer because it is calculatedby the LOADS program as a function of surface roughness andwi nd speed.The list identified by MATERIAL and THICKNESS must have aone-to-one correspondence. That is, the first materiallisted in MATERIAL has a thickness equal to the first valuelisted in THICKNESS.Both lists (MATERIAL and THICKNESS) must have the samenumber of elements.A list element must be included in THICKNESS for layersspecified by a RESISTANCE, but it is a dummy variable, usedonly to make the list length match with the I"1ATERIAL listlength.For an exterior wallar roof, both lists start with theoutside layer and proceed sequentially to end with the insidelayer. For an interior wall, interior floor, ceiling,underground wall, or underground floor, both lists start withthe layer on the opposite side and proceed sequentially to endwith the layer on the near side.Maximum list length for MATERIAL and THICKNESS is 9 elementseach.Not allon ly.layer.LAYERS can be specified by RESISTANCE (for MATERIAL)At least one must be specified as a transient typeIIL77 (Revi sed 5/81)
