Abstract:
The study aims to show the effect of the climate for planning and designing of residential buildings in Samawa city and its relation with consuming of electricity energy and harmony of these buildings with climatic conditions to get the physiological comfort of the human being. The study is consisted of five chapters,The first chapter includes the natural characteristics of Samawa city and its urban stages..The second chapter includes the study of the concept of physiological comfort in Samawa city and the effects of climatic and non - climatic factors in it depending on the data of the General Authority for Meteorology and Seismic Observations and using two criteria to detect the comfort, they are (Algiai's environmental climate chart and thermal analysis table). Through analyzing data by these two criteria , general biomechanical calendar showed that months of the comfort.The third chapter examined the relationship of climate elements by planning of residential areas . As this chapter showed the climatic impact that the vegetal cover was contributed to improve the local climate of external spaces and thus the effect it leaves within the residential units on the one hand and the climate relation to design that cover on the other hand. Also this chapter examined the effect of the planning elements of outer spaces on climate elements by using of the THI standard . So This study revealed the effect of cool wind in the outer spaces for the compact and open patterns. It has been observed that The compact pattern is closer to the comfort limits of the open pattern in most of the seasons. Whereas The measurement in residential units was dealt with in chapter four and by (THI). So this chapter, in its beginning , dealt with designing of residential buildings and their relation to the elements of the climate according to the design of the dark elements, including ceilings, walls, shape and guidance. So their effect on climatic conditions and climatic treatments and their relationship to the reduced climate in for the residential units. So this chapter dealt with the transparent elements, including windows and casements and their role in the passage of solar radiation , ventilation and lighting. The Field study of residential units , While the old residential units became from the comfort limits during the summer for the morning observations but came out of the comfort limits for the evening observations. while the modern residential units came out of the comfort limits during the summer for the morning and evening observatios. The fifth chapter : dealt with the relationship of the climate to consume the electric power in Samawa city. The study explained the effects of climate elements on the heat affecting the human comfort and its relationship to consume the supplied energy. It turned out that the supplied energy increases with high temperatures affecting the threshold of heat and decreases during its reducing below that threshold. So this study showed that there is a significant difference between the supplied and required energy, indicating the lack of supplied energy for Samawa city and explained the seasonal and monthly variation in energy consumption. Summerseason presided the other seasons in consuming of the energy and July is the hottest month in summer ,. So this study revealed that there is temporal and spatial variation to consume the electric energy in the Samawa residential units and during the six courses of measuring in those units. The fourth cycle (July and August) was the first of the other cycles in the consumption because of the high temperature . The study revealed that a strong and incorporeal correlation between temperature, wind and energy consumption. At the same time, it revealed the inverse correlation between relative humidity and consuming the supplied energy. The regression equation shows the predictability to need the required energy when the rates of temperature and humidity are changed.
