Abstract

Due to the transfer of environmental heat into buildings, requires consuming large amounts of electrical energy for absorbed heat gain. This study used sunflower seed husks as one of the industrial residues, as a waste material. These husks were ground into a nano-powder and blended with cement at a weight of 1:5. From this mixture made of 12 mm diameter balls then added back to the building block mix during formation. The thermal behavior of the walls constructed from these blocks was tested in the climate of Baghdad, during daylight hours on the 21st day of each summer month (May – July) in 2022. The optimal addition ratio was 4%, which achieved a heat load of 176.2 kW and an electricity consumption of 110.2 kWh, resulting energy savings of 18.1% compared with a traditional wall.
