Educational buildings have a large share and impact on urban development. While research shows a significant portion of non-industrial energy consumption in these buildings, obtaining optimal thermal comfort in educational buildings remains one of the main concerns in achieving the grounds to promote students’ best performance and efficiency. Extensive research has been done in this field, however, this research presents a new approach to the diverse use of nanotechnology techniques which improve its properties and components in the buildings, aiming to reduce energy consumption and increase thermal comfort. In this paper, thermal comfort and energy consumption is evaluated in a 12-class elementary school located in Shiraz City. Aeropan and nano-PCM is used in the window glass and walls of the studied case. This evaluation presents the simulation and experimental analysis of thermal comfort (PMV) and energy consumption of three classroom alignments in the school building including the Linear-shape (LS), the Integrated Linear-shape (ILS), and the U-shaped (US) alignment. The simulation was performed using EnergyPlus 9.6 software, while the experimental data was collected using TESTO 425 device. The result of this research shows that after applying nano-PCM and Aeropan techniques in window glass and walls, the US alignment has the highest reduction in energy consumption (annual monthly average of 11.80%) compared to LS and ILS alignments. This alignment includes an energy consumption reduction of 12.03% in the coldest, and, 11.66% in the hottest day of the year in addition to increasing the annual thermal comfort of school by the use of nanomaterials.

“…У зависности од оријентације фасадног зида, топлотно оптерећење у спаваћим собама може бити редуковано 24−31%, уз задржавање жељених услова комфора. У студији спроведеној на територији Мајманда (Иран) анализирано је преко 20 земуница са циљем да се кроз њихову геометријску и просторну оптимизацију побољшају услови комфора (Khaksar et al, 2022). Генерални закључак је да се пажљивим архитектонским дизајном услови живота у земуницама могу побољшати за преко 30%.…”

This paper investigates the energy potential of different modern earth-sheltered building types, during a seven-month period (October 1 to April 30), in order to achieve sustainable development. The subject of the research is a one-story residential building (total net area 102.5 m2), intended for a family of four, located in the territory of the city of Kragujevac (central Serbia). The heating system consists of a ground source heat pump, geothermal vertical probes, floor panel heaters, and two circulation pumps. Four types of infiltrated earth-sheltered buildings, as well as one elevation earth-sheltered building, were investigated by numerical analysis (using the EnergyPlus software). The energy performances of all of the mentioned earth-sheltered buildings were compared with the energy performance of classic above-ground buildings. All of the buildings have the same geometric, construction, and thermo-technical performance. The research results show that, in infiltrated earth-sheltered buildings, the annual consumption of final (electrical) energy can be reduced by 2.53-21.64% (depending on the number of external building elements in direct contact with the soil). Modern architecture should still be focused on the development of elevation earth-sheltered buildings because in them the annual consumption of final (electrical) energy for heating can be reduced by more than 40%.

“…[16] has explored a mixed-method adaptive comfort approach for understanding thermal comfort in vernacular dwellings in Mediterranean climate in Alentejo, Portugal. In the same way, [17] has studied, the thermal comfort of vernacular earth-sheltered buildings in Meymand, Iran. For all these studies on vernacular architecture, it has been concluded that these vernacular constructions have real thermal comfort during hot periods.…”

“…Most of these time lag and decrement factor studies have been based on scaled-down [21], or digital models [22]. Also, many studies on the hygrothermal behavior of vernacular architecture are carried out in Europe [15] [16] and [20] or Asia [17] and [19]. This building is also remarkable for its architectural form, its construction system with its double protection, its courtyard and its strategies for adapting to its environment.…”

This study analyzes the know-how of local communities, to draw on techniques that make contemporary buildings more energy efficient. The impluvium hut in the locality of Enampore, Casamance, Southern Senegal, served as the object of study. The hut, including several rooms, is entirely built with earthen walls, earthen floor, earthen ceiling, covered by a double straw roof and its central courtyard. A room noted (L) and a semi-opened living space were chosen as spaces for hygro-thermal experimentation. The hottest average temperature obtained respectively in the room (L) and in the living space is 25.5˚C and 27˚C when outside is about 34˚C. The thermal amplitude inside room (L) is 0.88˚C, in semi-opened living space, is 2.6˚C and outside is 9.5˚C. With these results we can say that room (L) undergoes very low temperature variations and that there is no need to air-condition in the enclosure. The thermal amplitude makes it possible to see the influence of the earthen walls on the interior temperature and its regularity compared to the fluctuation of the external temperature. The thermal inertia of the building walls was characterized using also the time lag and the decrement factor. They was respectively 7.0 H and 0.093 for the room (L). With this result we can say that this material has a high thermal inertia. For humidity, it is high around 78.5% in the room (L), 66.0% at the semi-open living room, when it is 59.0% outside. Through this study, it is possible that the revalorization of vernacular architecture can be an alternative to reduce the energy consumption of buildings.
