Examining the combined use of green buildings and clean energy

Due to the increasing trend of the population living in cities and the decrease of green spaces will cause many problems such as air pollution and more respiratory problems. Statistics have shown that from ۱۳۶۹ to ۱۳۹۹, there was a twenty percent increase in energy consumption, which was done in order to heat or cool the buildings. It also shows the reduction of fossil energy reserves ,and on the other hand, the destructive effects of this type of energy on the environment. It is necessary to use green walls and new energyies in buildings as one of the useful solutions to conserve energy. The green wall is considered as an insulation for the building, which can minimize the use of energy in different seasons by reducing heat loss. This research, with a descriptive method, examines the documents for the introduction of green buildings and the reduction of energy consumption by them and the use of clean energy as an alternative. The results have shown that there is a ۵۰% saving of heating and cooling energy in a green building compared to a conventional building, and the use of triple-glazed windows in a green building instead of conventional windows reduces energy loss by approximately ۹۱%.Also, the change in the material of the green building, compared to the conventional building, causes a decrease of approximately ۴۱ and ۱۱ percent of energy consumption, respectively. On the other hand, the use of green roof is very useful in reducing energy consumption, and also with the increase of building floors, the use of green wall vegetation with suitable plants and on the eastern side of the building shows a very good performance. These results show the necessity of using this. It reveals the solutions in the design of each high-rise building.
