Double stud walls are a way to provide enough insulation to build a net-zero energy home. In some double stud walls, 2×4 southern yellow pine boards" are alternated on either side of the wall as shown in the cross section below. The interior wall is faced with a 1-in. thick gypsum board. The exterior of the interior studs is faced with a 1/2-in thick plywood layer. The exterior wall is faced with another 1/2-in thick plywood layer and a clay brick (4-in wythe) veneer. The empty space is filled with dense-packed cellulose insulation (4 lbs/ft³ according to the manufacturer's data sheet). What is the dead load of a 12-ft tall section of this wall assembly per horizontal linear foot? (Note: 2x4 boards are actually 1.5"x3.5" in dimension)

Voids are sometimes intentionally created in the precast slabs to:   Question 2 options:   reduce weight   maintain fire rating   increase thermal insulation   all of the above
