“…In other words, at a sufficient depth, the soil temperature is lower than the surface air temperature during daytime (the trend is opposite during night-time). Therefore, soil temperature is seemingly a key factor in affecting the heat transfer of an underground building and the thermal storage for new sources of renewable energy [3][4][5][6][7]. Therefore, the investigation of soil temperature at different depths is necessary to calculate the heat flux through the building surface.…”

Abstract. In this study, the soil temperature profile was computed based on the harmonic heat transfer equations at various depths. The meteorological data ranging from January, 1 st 2016 to December, 31 st 2016 measured by local weather stations were employed. The findings indicted that as the soil depth increases, the temperature changes are negligible and the soil temperature is nearly equal to the mean annual air temperature. Likewise, the results have been compared with those reported by other researchers. Overall, the predicted soil temperature can be readily adopted in various engineering applications in Malaysia.

“…In addition, the current status of use of earth as a building material and adaptations of vernacular architecture for improving energy efficiency in modern context were presented along with a case study of the vernacular architecture of a location in Himachal Pradesh, India. Hazbei et al [42] investigated underground shelters in the hot and semi-humid city of Dezful in southwest Iran. This type of underground shelter, known as Shavadoon, is considered a passive energy strategy to seek temperature comfort using the annual temperature stability of the earth and natural ventilation.…”

Effects of Vernacular Climatic Strategies (VCS) on Energy Consumption in Common Residential Buildings in Southern Iran: The Case Study of Bushehr City

et al. 2017

Abstract:This study aims to use the vernacular climatic strategies (VCS) of traditional dwellings in Bushehr, in the common residential buildings of this southern Iranian city (which is characterized by its hot and humid climate), and provide answers to the following question: What effects do VCS have in terms of energy consumption in these buildings? This study has been conducted at three levels. At the first level, three context-based climatic solutions including shading, natural ventilation, and insulation of external walls and roofs were identified and selected based on bibliographic study. At the second level, a case study reflecting the current typology of common residential buildings in Bushehr city was selected. A combination of the mentioned climatic solutions was used in the baseline case to create a developed model. Based on the space layout of the developed model and some design criteria, a series of proposed models was also created and modeled. The selected case study building was also used to establish a local weather station at a height of 12 m based on the roof, collecting local climate data which were then used for simulation to improve simulation accuracy. Finally, all models were simulated with the use of Design Builder software under natural ventilation conditions during moderate climatic periods of the year while split air-conditioning systems were used during hot and humid periods. The results showed reductions of 16% in energy consumption and 22% in CO 2 emissions for the developed model, and reductions of 24-26% in energy consumption and 32-34% in CO 2 emissions for the proposed models, as compared with the baseline model. Furthermore, all proposed models achieved lower annual energy consumption when compared with a selection of international sustainable low energy standards and domestic energy performance references for the Middle East region. Further studies are also recommended, and there is potential for combining VCS with other solutions such as on-site renewable energies.

“…Different types of courtyards of Chinese vernacular houses in a hot and humid climate perform different functions in improving indoor thermal comfort [35]. Another study indicated that using Shavadan spaces in traditional houses in a hot and humid climate can create thermal comfort and help to reduce cooling and heating loads [36]. Studies of passive strategies in vernacular houses in India revealed the relation of vernacular architectural features to thermal comfort conditions [13,37].…”

Influence of Iwans on the Thermal Comfort of Talar Rooms in the Traditional Houses: A Study in Shiraz, Iran

2018

In traditional buildings many climatic strategies have been used to provide indoor thermal comfort in south and central parts of Iran. A common element is called an iwan. This study investigates the indoor thermal comfort of a room adjoined to a talar in a traditional house which has an iwan, in Shiraz, Iran. The data related to the temperature and relative humidity of the room are used to calculate the thermal comfort index of PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) by considering the following two cases: a talar room with an iwan and one without an iwan, by means of DesignBuilder software. For the purpose of validation, the air temperature and relative humidity of the talar room with an iwan were measured over 10 days and compared to the results of the simulation. Having a valid simulation, computation was conducted for the selected house in various cases for an annual passive operation of calculating PMV and PPD. The numerical results revealed that the talar room adjoined to an iwan located in the south front of the courtyard had relatively good conditions during the hot months, including June and July. In addition, it could provide fully satisfactory comfort conditions during August and September. According to the results, it is found that the iwan makes a talar room 62% more desirable for the hot months in comparison with a talar room without an iwan.
