In addition to attention to natural light as a renewable, costless and environment-friendly source of energy in the late 20th century, numerous studies have been conducted into the effect of natural light on human being’s soul and body and all such studies reiterate the undeniable role of natural lighting on people’s behavior, attitudes, and efficiency. However, in spite of the awareness of the effects of natural light on human beings as well as on the environment, source of lighting in most buildings is still limited to artificial lighting and most of the solutions used in the old architecture with regard to the use of natural lighting have been forgotten nowadays. This paper, based upon a holistic approach and a qualitative research method analyses a few traditional houses in Hot and Dry climate of Iran and showed how their builders by using architectural elements as well as different methods of space organization so to better use light to satisfy the physical and psychological needs of the inhabitants,including visual and heat comfort, health, introducing  variety and increasing space quality. As we will see, this research describes the methods they tried to create a balance between physical and psychological needs of the inhabitants and to supply the required energy.

Constructed upon a height (by footing) or breaking in to the ground, in a building, making a close relation between earth and soil is of great importance. In addition, earth as a prior factor in creation of a shade and residence, plays a crucial role in architecture history. Throughout the different area, earth is paid attention differently: as a source of cool (in China), a source of heat (Cappadocia, Turkey), and conversely as an offensive source in Amazon forests. In hot-arid climates, proximity to earth is useful to apply the heat in the buildings. Present study aims to investigate the mentioned factor in Dastkand village located at Kerman province. Mountainous moderate climate, cold and icy winters and moderate summers is of the considerable properties of the studied area. The maximum and minimum temperature was recorded, 42 and -18° C during summer and winter, respectively. Hence, in addition to cultural as well as economic factors, temperature fluctuation played a key role in breaking the buildings in to the ground. So, this study assists to investigate the studied area within natural bed, in plan and section. On this basis, technical methods of earth profiting throughout the studied area have been investigated, in order to profit earth in modern architecture. Results showed a harmony between dominant winds and buildings in winter and summer. Moreover, profiting from high sun shining with special architecture is of Meymand village characteristic. Using breaking in to the ground technique, 26.57 % decrease occurred in cooling need, annually. On the other hand, Day-Degree heating need has reduced to approximately 13.65 % annually solely by earth profiting technique. Overall, results demonstrate a harmony between applied technique and the studied region climate. Besides, there reported a proper isotropy between temperature fluctuation and air aridity throughout the region.
