Abstract

In the building sector, the choice of the materials utilized in building the wall is dependent on many factors. Some of the factors that affect the choice of the materials are the bearing ability, water resistance, available thicknesses, cost, heat transfer, availability in the market and other factors. Designers always set one of these factors as their primary objective, while setting the others as subsidiary objectives of less importance which may be neglected in some cases. The goal of this research is to develop an approach for selecting the materials needed for building laminate composite walls that can achieve two objectives at the same time, which are minimum cost and minimum heat transfer through the wall. While considering the bearing conditions of the materials for the wall to be able to withstand the loads acting on it, and considering the required thickness constraint of the wall. The approach is divided to two steps, starting with the optimization part that gives the optimum set of materials for each number of layers separately, and then this optimum set of materials is used to calculate the accompanied transient heat transfer through the wall based on the location and orientation of the wall. The cost and actual heat transfer for each number of layers is finally presented to the designer to select the most suitable alternative. This approach would help construction designers for building thermally and economically efficient walls for residential or non-residential buildings, and can also be used in building walls of furnace or in building chambers where thermal efficiency is of major importance.
