Quantity of Light Trough Glassblock Wall

Glass block as building material has many advantages. As transparent material, glass block can both transmit and diffuse light penetrate it. There are many kinds of glass block pattern and color which can affect the light transmission. This research attempts to seek the quantity of light through glass block wall. The research was conducted by field experiment using 5 model boxes, size 1m x 1m x 1m; they were 3 mm standard clear glass, three different glass block types and one with 1 side remained open, called under-shade. The measurement found that glass block pattern and its structural depth reduced the light quantity and increase uniformity toward the center and the ceiling position compared to 3 mm standard clear glass.
