“…In this regard, it is worth mentioning previous studies on vernacular construction housing concerning thermal comfort, demonstrating positive attributes of ancestral construction systems. [14] [12] [15]. Various parts of the world investigate vernacular architectural characteristics in different climatic zones and with diverse materials, including their physical, mechanical, and thermal properties, as well as location-specific design strategies [16] [17] [18].…”

Traditional Ecuadorian architecture refers to structures whose technical and visual characteristics date from pre-Columbian times to the mid-20th century. However, such architectural interventions can still be found in the Andean region, mainly in remote villages away from urban centers. Among the architectural features, ancestral knowledge passed down through generations and a construction system based on mud, wattle and daub, adobe, and other materials. The analysis aims to develop thermoenergetic simulations to identify the thermal comfort of buildings in Pilahuin Parish Center (Ambato, Ecuador). The methodology is based on a qualitative and quantitative approach, and using non-probabilistic random sampling, the following main variables were analyzed: geographic orientation, type of layout, building height, materiality, and number of floors. After surveying and architectural drawing of the buildings, 3D models were developed using Autodesk REVIT software. Consequently, digital three-dimensional architectural models were imported into Design Builder software. This process generated a diagnosis of the current state of the buildings in terms of habitability, based on interior thermal comfort. The results showed an average indoor air temperature of 18.77°C and an average relative humidity of 50.76%. With this data, strategies were developed to improve habitability based on Olgyay’s theory of architecture and climate. The resulting data, also obtained in Design Builder, allowed for a proposal to achieve the average indoor air temperature and relative humidity within the optimal ranges of Olgyay’s theory and the Ecuadorian Construction Standard. Therefore, by making certain material changes while respecting their heritage value, thermal discomfort levels were improved by 27.67% compared to the analyzed interior temperature, thereby enhancing the quality of life for the inhabitants.

This study examines the thermal and energy performance capabilities of composite structural insulation panels (CSIPs) for traditional Korean architecture, specifically Hanok. Hanok buildings, renowned for their cultural and architectural significance, often face thermal efficiency and energy consumption challenges. This research aims to explore the environmental potential of CSIPs to improve the thermal performance of Hanok structures while maintaining the traditional aesthetics of these buildings. Simulations were conducted to analyze the thermal behavior, heat flow, and energy use intensity (EUI) by wall cases of Hanok buildings, applying continuous-fiber-reinforced thermoplastic composites as a type of CSIP. The findings demonstrated that applying continuous-fiber-reinforced thermoplastic composites (CFRTCs) to the target Hanok building significantly enhanced the thermal performance, including the thermal bridge and envelope airtightness, as these composites can reduce the thermal conductivity and minimize heat loss, thus improving the insulation capabilities. Furthermore, adopting modular CSIPs in Hanok architecture offers environmental benefits and aligns with sustainability and constructability goals. By reducing reliance on mechanical heating and cooling systems, CSIP-enhanced Hanok buildings can contribute to lower energy consumption and greenhouse gas emissions. This simulation study highlights the significant potential of CSIPs with fiber-glass-reinforced thermoset (FRT) polymer skins to enhance the thermal and energy performance of traditional Korean Hanok buildings. CSIPs as applied to the target Hanok can potentially reduce heating energy consumption by approximately 21% to 29%, leading to overall energy savings of about 4% to 5% in site EUI and CO2 emissions levels per unit area.
