Outdoor atriums have recently been applied with increasing frequency for natural illumination, but they produce a harsh thermal environment easily in summer. Moreover, overheating of the outdoor atrium necessitates air-conditioning to moderate indoor comfort. Simultaneously, substantial heat emissions from units worsen environment, creating vicious cycle.

Abstract The self-insulation-sintered bricks are widely employed in the walls of green buildings with obvious advantages thermal insulation performance and avoiding secondary construction a single layer. link ribs sintered brick essential components to ensure its mechanical performance, as well directly affecting brick. Therefore, can be regarded bridges self-insulating bricks, where their heat transfer characteristics affect performance. To improve self-insulation paths optimized three proposed. numerical simulation is calculate process. results show reduce peak average values surface flow, thereby resistance analytical units. Compared traditional rib, resistances were diminished by 0.84%–6.44%, 4.46%–12.73%, 9.93%–24.69% for inclined offset curved respectively, while they lowered 7.34%, 7.92%, 13.43%, increasing setoff distance from 8 mm 24 mm.
