چکیده:

In recent years, using of air-conditioning devices at summer season has been increased considerably specially in cities that are located in hot climate regions. Most of big cities of Iran are in hot and dry climate area, so utilizing of air conditioning system has been growth noticeably in last decay. According to scientific collected data, consumption of electricity in an average apartment is around 35% of total electricity consumption. Also the consumption of electricity in hot season is two times greater than cold season. So, it is clear that using air-conditioning and cooling systems is the main reason of this great amount of energy consumption and near 30% of energy use in air-conditioning systems. Considering of this subject, efforts to decrease saving electricity in these big cities is an important national issue. In this paper regarding to applications of passive energy technology in residential or office buildings, new methods have been investigated to improve new buildings in these cities. After investigation of these innovative methods for using passive energy in cooling and air-condition system, two methods has been collected that are suitable for big cities of Iran which are located in hot climate regions. Using advance cool tower in buildings and passive radiative cooling are two appropriate methods for very effective summer cooling strategies and effect of these methods on energy management in these cities has been study analytically.
