In recent decades, the destructive effects of excessive consumption of non-renewable fuels and lack of attention to the concept of sustainability have caused significant damage to the environment. Eliminating natural resources and making destructive climate change is a direct impact of human effort on achieving modernity, an endeavor which has a positive purpose but destructive manner. The problems created, including rising ground temperatures and many of the problems raised, have attracted the attention of the people of all countries. According to reliable reports of research centers, about 40% of energy consumed by human is consumed in the building sector, so attention to the building sector is very important. From the principles of sustainable architecture are optimum energy consumption and reduced thermal losses and the use of renewable energy. Today, modern technologies of the word "intelligence" is very important. In fact, it could be argued, that in the near future an important part of modern technologies, will be related to intelligence. These changes will happen in the building industry and even today it is visible start. The purpose of this study was the comparison check of the thermal conductivity coefficient of a particular type of an external wall with smart Aerogel insulation compared with the thermal conductivity coefficient of the same type of wall but without insulation. In the studies, a similar sample of this case was not observed, this research is innovation and unique. Two test chambers one to test and the other to control were constructed for the purpose of the research. The southern walls of the two test chambers (the main wall) were designed to make changes to independent variables. The purpose of the research is to use smart Aerogel in external building covers, and because of the intelligence or controllability has not yet been made, the intelligence function is performed by simulation ( the function of the smart Aerogel is simulated by hand) and its results will be investigated.The external wall with smart Aerogel insulation (intelligence is manually applied) is the main program of this experimental and innovative research and the results of the tests were compared to the control chamber, which was completely similar and just without insulation. The first reason for the use of the Aerogel insulation was due to the excellent insulation properties of the material (the Aerogel is the best insulation in the world which has been ever discovered), and the second reason was because of according to the some research institutes in the science of materials (Department of Chemistry in the University of Tehran) the possibility of making smart Aerogel insulation is possible which they response to environmental stimuli. . The results of this study proved the positive effect of the external wall with two layers of the smart Aerogel insulation compare to the same type of wall but without insulation and The research showed that the test chamber with the smart Aerogel insulation, considering all test conditions compared to the same control chamber without insulation Transmits more than 28.8 ± 0.9 KJ into the test chamber during the 24 hours.
