Evaluation of Thermal Comfort in Residential Spaces of Rasht City

The importance of climate and its impact on human life is not hidden from anyone. The expansion of urbanization and development of cities along with the rapid growth of population and development of industrial activities has greatly reduced the thermal comfort in residential spaces, the consequences of which in the short term in the form of diseases and illnesses to city dwellers and in the long run as a factor in intensifying climate change. Its environmental effects, including the change of favorable months in terms of comfort climate, play a role. Meanwhile, the high costs of establishing comfort in residential spaces by mechanical devices and especially their maintenance, as well as its consequences in environmental degradation, has increased the importance of urban climate research. Therefore, the view of this study is to investigate the effect of climate on physiological comfort and convenience of human beings in closed spaces under the influence of two elements of temperature and humidity.

The purpose of this study is to analyze and evaluate the effect of climate on physiological comfort and convenience of humans in closed spaces under the influence of two elements of temperature and humidity.

The research is an applied type that has been done by descriptive-analytical method. The data used include average minimum, maximum and daily temperature, relative humidity, vapor pressure and dew point temperature in the statistical period of 40 years (1979-1979). For data analysis, indices of discomfort, temperature-humidity, sultry intensity and AIA standard were used.

Studied Areas: 

The study area in this research is Rasht city in Guilan province.

The research findings show that heat discomfort reaches its maximum in July and August and also August has the highest amount of sultry.

The results of the study indicate the greater effect of temperature element on the establishment of thermal comfort because despite the low relative humidity in the four months of June, July, August and September compared to other months, the degree of sultry and lack of thermal comfort in this month It reaches its maximum, which in addition to creating shade, also needs natural air ventilation to establish thermal comfort.
