Grooved Wall

In this case, grooves with various spacing were cast at each row. The series utilized ten different 3D printed inserts ranging from 2, 3, 4, 6, 8, 12, 16, 24, 32 and 48 grooves per mold. Molds were placed in a gradient starting with 2 grooves per mold at the bottom row gradually increasing the number of grooves on every subsequent cast as the wall was built. All grooves were oriented vertically. As a result, the mockup showcased a textured surface with a strong vertical pattern (Fig. 2D & 3D). An intrinsic characteristic of this study is the generation of a texturize surface which grooves can serve as geometric actuators of thermal flows by varying surface area while keeping the concrete mass constant. Sophisticated surfaces call for further explorations such as the relationship between surface geometry patterns and heat transfer coefficients in thermal mass passive systems.
