Abstract
The effect of economic and population growth rapidly contributes to the energy usage of buildings increasing to high levels. To minimize the electrical energy consumption (EC), thermal insulation of wall has significant impact to minimizing the EC of building. The aim of this paper is to define the influence of wall on reducing EC of residential building with different wall characteristics. In this case, two different kinds of building characteristics were evaluated, namely: building-1 applied an innovative Cellular Lightweight Concrete (inCLC) brick and building-2 with wood applied to create the walls. Under numerical optimization, a mathematical model was developed to define the EC of air conditioning (AC). Based on the result of research indicated the EC of building-1 (IDR 25,365) was cheaper than building-2 (IDR 29,350). Consequently, the energy cost reduction (ECR) can be achieved to be IDR 3,985 (13.57%).
