Assessment of energy efficiency in buildings using synergistic walling material Available to Purchase

Energy-efficient buildings assist in conserving energy and are currently prioritised due to increases in the cost of energy and greenhouse gas emissions. In this investigation, a low-thermal-conductivity walling material (bricks) was developed using co-fired blended ash (CFBA) for conserving energy in buildings. Physico-mechanical properties of the developed product were investigated according to Indian standards. Also, the thermal conductivity of the bricks was investigated. Building performance analysis was carried out with the help of a case study. Computational models for the single- (G), double- (G + 1) and triple- (G + 2) storeyed buildings were designed using the Autodesk Revit tool. The developed models were analysed for energy efficiency using building information modelling. With respect to fly ash bricks, the CFBA brick model estimated a 5% reduction in number of bricks as well as the dead load of the structure and resulted in peak cooling load reduction by 8, 11 and 15% for G, G + 1 and G + 2 storeyed buildings, respectively.
