Reducing Energy Consumption by Using Feathers as Chicken Residues in Solid Concrete Materials (Experimental and Numerical Study)

The research aims to determine the faculty of direct use of chicken feathers as an additive in manufacturing of solid concrete building materials. During this investigation carried out, the chicken feathers content ranged from 2.5%, 5%, and 7.5% of the total volume of concrete mix. Concrete building materials specimens were grouped and tested according to their climatic and construction conditions of Baghdad city (latitude 33.2 N°) and for the 21st of each month of the summer seasons (May to September 2020). The researchers found that the use of concrete building materials of (7.5 %) chicken feathers content, additives resulted in a cooling load of 50.75 kW/m2 for the summer months for one meter of wall, while the consumption of electric power for air conditioning was 16.8 kWh with a 37.6% consumption reduction percentage compared with the traditional wall consumed, while concrete mass density dropped to 14% of the traditional mass.
