The comparative study of the geographical directions of rural housing and energy consumption in Sistan

Using proper methods in designing buildings being compatible with the climatic conditions of a region has always been important for builders. It has been common in our country for a long time to consider natural and inexhaustible energies such as the sun, wind and to improve the thermal conditions in inhabited areas. Using these energies in buildings leads to saving energy, and significantly it improves the comfort level and sanitary conditions in inhabited areas. To control the inside space of a building, the first step in using natural energies is to adapt the building and the environment in general to the climatic conditions of that place. So far the degree buildings’ facades in different geographical directions being compatible with climatic conditions has not been studied to measure how it affects energy consumption levels and expenditure; so the researchers examined energy consumption level, consumption expenditure, and the level of satisfaction with temperature inside the building ant their relation with the geographical directions of buildings’ facades. To do this study, three methods have been used: documentary resources, fieldworks and questionnaire. SPSS has been used to analyze the data. The findings show a significant difference between the buildings’ facades and the level of energy consumption. Buildings with northern façade had the most levels of the following objective factors: energy consumption, hours the heating and cooling systems being on and the whole consumption expenditure of families. On the contrary, buildings with southern facades had the least levels of the above mentioned factors. In addition, the level of satisfaction with the heating and cooling systems inside the buildings during hot and cold seasons as subjective factors was studied. Families whose buildings had southern facades had the most level of satisfaction. But families whose buildings had northern facades had the least level of satisfaction.
