The research presents a scientific approach for analysis of EMR levels indoors. A MATLAB program was created to evaluate the transmission, absorption and reflection through a model five-layered wall. Curves illustrating the effect of brick size on transmission and reflection were constructed. The effect of replacing regular cement in the wall render layers with four types of new treated cement mixtures was first investigated on the model wall. The EM environment of a square room with the model five-layered walls was evaluated. CST-MWS software was adapted to simulate EMR behavior within the model room with high precision. Five roof shapes were analyzed and compared. The effects of openings, height change, and orientation on EMPD were analyzed. The full pictures of the EMR distribution patterns were presented by taking sections along the lengths and widths of the studied buildings, constructing EMR density curves at different heights, as well as evaluating EMP intensities at four selected points within the utilized regions of the studied buildings. An optimization for the wall layers thickness was achieved through extensive simulation
