Mass walls are defi ned as “a wall with an HC (heat capacity) exceeding: (1) 7 Btu/ft2 x oF, or, (2) 5 Btu/ft2 provided that the wall has a material unit weight not greater than 120 lb/ft3.

Heat capacity is defi ned as “the amount of heat necessary to raise the temperature of a given mass 1oF. Numerically, the HC per unit area of surface (Btu/ft2 x oF) is the sum of the products of the mass per unit area of each individual material in the roof, wall, or fl oor surface multiplied by its individual specifi c heat.
