Abstract
The growing process of building design and construction, regardless of reducing sources of energy,
is one of the threats to the environment and human life. Therefore it is necessary that design
strategies in new buildings be orientated to the aim of reducing energy consumption and environmental
pollution. Earth sheltering is a passive idea that reduces building energy consumption
and ensures its thermal comfort to a great deal. Taking shelter in the earth and advantage from its
thermal properties is one of the tricks that even was used in some climates in the past. This study
investigates the energy efficiency of Earth-sheltered building with regard to the interaction of different
building uses in the city of Yazd. The thermal simulation software (EnergyPlus) was applied
to accomplish this aim, following the study of the basic requirements of a specific research on
this subject. Regarding the results, increasing in the depth of penetration in the soil, increases the
percentage of savings compared to aboveground conventional buildings. In this condition, with
increase in the depth of building position, residential use has the most and educational use has the
lowest correlation with energy consumption. And also the optimum depth for each building use is
assessed at a different rate. In this situation, residential use has 69% and religious, administrative
and educational uses respectively have 61, 60 and 54 percent energy savings.

Abstract
Different sensory stimuli, such as light, color, smell, sound and texture, play an important role in perceiving the quality of an environment. Heat, like other sensory stimuli, can contribute to the richness of an environment and provide a greater benefit to people. The fact that a person in addition to the thermal comfort of a particular environment can also benefit from its thermal quality, is a desirable point that can be considered by designers and architects.The idea, called "thermal pleasure", aims to make people percept the thermal quality in addition to its quantity, which has a numerical aspect. This issue can provide a basis for changing the study of thermal comfort in the field of architecture. Along with different complementary theories that try to understand thermal comfort more accurately, the concept of thermal pleasure has a qualitative look at it, considering the living environment. Since the discussion of the factors and relationships that shape thermal pleasure in the built environment has not been studied so far, it is necessary to extract these factors based on lived and real human experiences and determine the relationships between them. This study uses grounded theory, as a qualitative method, to provide a theoretical framework for the formation of thermal pleasure in the built environment. The findings of this study show that from the cooperation between thermal distinction and the messages received from the environment and the thermal resource, other factors that activate thermal pleasure are manifested from four aspects: physiological, psychological, behavioral and value. Nevertheless, according to the economic and socio-cultural and spatial context, the type of peoplechr('39')s perception of thermal quality also differs. The theoretical framework presented in this research helps to provide a stronger basis for designing future research as well as data collection following the study of thermal quality in the built environment.

Abstract
Determining the range of thermal comfort in the outdoor space is complicated, and since the presence of thermal comfort helps more people to be in the outdoor space, it is important. In the current research, it has been tried to determine the thermal comfort limit of people in the outdoor space of traditional and restored buildings in the hot and dry climate of Yazd city. For this purpose, a field monitoring was carried out in the hot season of the five central courtyards of the Yazd faculty of Art and Architecture as buildings that have been changed from residential to educational use, which includes the measurement of climatic information at the same time as the completion of 389 thermal comfort questionnaires by the students of the faculty; Then, with the help of Ray Man and SPSS software, the obtained information was analyzed and after checking the linear regression charts, the range of thermal comfort for people in the central courtyards of the faculty as a microclimate in the hot and dry area of Yazd city between the range of 16.5-28 degrees Celsius based on the Physiologically Equivalent Temperature index (PET) was obtained. Due to the fact that the combination of climatic and geographical factors for each specific region will lead to a different understanding of the thermal comfort conditions for the people of that community, this comfort range is different from the comfort ranges in other regions that have been determined in numerous researches. From the comparison of the studied yards, it was found that the more the yard has a height-to-width ratio and the more enclosed it is, the more shade it will receive and, finally,more thermal comfort during the day and night for the hot days of the year.
