Urban heat is one of the current climate problems due to conventional concrete materials and the high density of building blocks surrounded by. This study developed new building materials for concrete walls that reject the sun’s heat and reduce heat absorption on the walls. The new building panel was made of a hybrid foam (HF) composite concrete with a polymer matrix. The composition of polyurethane foam and cement with various fillers from ordinary Portland cement (OPC), white Portland cement (WPC), and rice husk ash (RHA) were explored and analyze the effect of using each filler on heat absorption and release. Measurements were carried out on a laboratory scale, using a 250 Watt IR lamp as a heat source, a thermal sensor and the microcontroller Arduino unit to record the temperature change during measurement of the surface and bottom of the panel. The use of WPC cement as a material for panels is better than OPC cement in reducing heat. On the other hand, the use of a polyurethane polymer matrix for hybrid foam and the addition of RHA to the filler has been proven to improve the performance of the panel in reducing the IR radiation absorptivity of the panel and releasing heat faster than without polymer and RHA.
