Solar energy in contemporary Iranian constructions

Sun is not only an enormous energy source, but also is the source for life and all other energies. According to the scientific estimations this fireball has existed for about 6000 million years and about 4.2 million tons of the sun mass is converted to energy each second and this glamorous star can be counted as a huge energy resource for the next 5 billion years. All the fossil, wind, waterfall, and sea wave energies depend on the energy received from the sun. The primitive humans used nature to shelter themselves from the nature, and due to the need to be permanent, different climate-based architectural methods were developed. The sun, water and wind were the three main elements utilized to bring about comfort and ease in constructions. After the industrial revolution utilizing the climate situations to provide comfort were replaced with artificial methods to do so. Ignoring the nature, problems caused by fossil fuels, and their short life in comparison with the sun, has made architects and designers to use natural factors and especially solar energy as the head factor in their designs. And nowadays we can see structures which are aimed to make the most of the solar energy. The items studied in this research are: the specifications of utilizing solar energy and its uses, Active and inactive systems, the importance of utilizing renewable energies in Iran, and studying cotemporary examples which have benefited from solar energy such as Supreme Audit Court Building, solar building of Science and Technology University and energy Museum Park in Neka city
