Studying the Thermal Behavior of Winter Sections in Yazd Traditional Homes and Its Optimum Situation

For over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. Residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand,traditional buildings of Iran were designed according to ecological conditions upon which, winter or summer sectionswere built. In this article, first, winter section of Yazd traditional homes, which are in hot-arid region and its thermalbehavior, will be studied. This computer simulation is done and validated with energy-plus software, and temperaturechanges of these sections were measured with lascar electronics data logger. The results confirmed its reliability.Second, sections with different proportions such as three-door room, five-door room and seven-door room in differentorientations, and their thermal behavior are analyzed and compared. So the thermal behavior of winter sections inYazd traditional homes during a year shows that in winter, the proportions of five-door room in northwest orientationis better than others.
