For over the past several decades, there has been a great concern about energy crisis and lack
of non-renewable resources. Residential buildings take more than 25% of the total energy consumption and more
than 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 sections
were built. In this article, first, winter section of Yazd traditional homes, which are in hot-arid region and its thermal
behavior, will be studied. This computer simulation is done and validated with energy-plus software, and temperature
changes 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 different
orientations, and their thermal behavior are analyzed and compared. So the thermal behavior of winter sections in
Yazd traditional homes during a year shows that in winter, the proportions of five-door room in northwest orientation
is better than others.
