Precast wall systems and methods for constructing a high-rise building using the precast wall system is disclosed. In one embodiment, the system includes a plurality of interconnected precast panels, each having a top end plate, a bottom end plate, a plurality of vertical bars disposed between the end plates and a cementitious material encasing the vertical bars and defining a plurality of sides of the respective panel. A first of the precast panels has a first column member half defining a right side of the first panel, a second of the precast panels has a second column member half defining a left side of the second panel such that, when the right side of the first precast panel and the left side of the second precast panel are disposed horizontally adjacent to each other, the first column member half and the second column member half collectively form a column member.

A building assembly includes a plurality of expanded polystyrene wall panels, headers, sill panels, U blocks, U block caps, roof panels, and connectors. Each U block includes rebar and at least one of concrete and cementitious material in a recess or void therein. Each U block cap when joined to the U block creates an enclosed void in the U block which holds the rebar and concrete and/or cementitious material. A plurality of capped U blocks joins a plurality of wall panels, headers, and sills to form a wall structure. A plurality of U blocks are placed on a top surface of the wall structure. A roof assembly including a plurality of U blocks, H connectors, T connectors, and combinations thereof connected to roof panels to form a rigid roof assembly. A coating of cementitious material provides additional structural rigidity and resistance to impact, fire, water, mold, mildew, and insects.
