Abstract

Energy crisis and pollution are two main challenges that hinder sustainable development in Egypt. Electricity represents the major part of Egypt energy; however, the Egyptian electricity consumption is increasing much faster than capacity expansions which causes electrical blackout. Egypt’s electricity prices began to rise starting July 2015 as part of a plan to reduce the government subsistence on electricity and force people to rationalize the consumption. Residential buildings are representing 40% of the total energy consumption, in Egypt. This is mainly due to a poor design of buildings, with no concern to neither materials used nor building tightness. This results in high cold bridges that increase the heat transfer from the outside to the inside of building spaces leading to high internal discomfort. Concomitantly, impacting the increase of energy consumption in cooling and heating today in most Egyptian buildings. This paper is part of a multiphase experimental research work that represents an empirical comparative study of different thermal walls’ created from recyclable materials. The results would be analyzed in details, developed, and evaluated in terms of; technical, economic and environmental aspects and conditions. As a result of this study; the walls of such economical homes will be able to resist heat transfer with lowest possible cost and consume less energy.
