Abstract

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.‎‎ ‎
