Urban morphology plays a decisive role in regulating microclimate and outdoor thermal comfort in arid cities, where extreme heat and intense solar radiation amplify thermal stress. This study examines the influence of four contrasting urban fabrics in Béchar (Algerian Sahara): the vernacular Ksar, the regular-grid colonial fabric, a modern large-scale residential estate, and low-density detached housing, on local microclimatic conditions. An integrated methodological framework is adopted, combining qualitative morphological analysis, quantitative indicators including density, porosity, height-to-width ratio, and sky view factor, in situ microclimatic measurements, and high-resolution ENVI-met simulations performed for the hottest summer day. Results show that compact urban forms, characterized by low sky view factor values, markedly reduce radiative exposure and improve thermal performance. The vernacular Ksar, exhibiting the lowest SVF, records the lowest mean radiant temperature (approximately 45 °C) and the most favorable average comfort conditions (PMV = 3.77; UTCI = 38.37 °C), representing a reduction of about 3 °C, while its high-thermal-inertia earthen materials ensure effective nocturnal thermal recovery (PMV ≈ 1.06; UTCI = 27.8 °C at 06:00). In contrast, more open modern fabrics, including the colonial grid, large-scale estates, and low-density housing, experience higher thermal stress, reflecting vulnerability to solar exposure and limited thermal inertia. Validation against field measurements confirms model reliability. These findings highlight the continued relevance of vernacular bioclimatic principles for sustainable urban design in arid climates.

Understanding the formation logic and spatial organization of vernacular settlements requires analytical approaches that capture both morphological structures and the cognitive rules underlying residents’ interactions with space. However, existing research on rural spatial patterns has paid limited attention to the perceptual and cognitive mechanisms through which spatial genes are recognized, maintained, and reproduced. This gap limits the development of generalizable and bottom-up methods for interpreting and transmitting rural spatial characteristics. To address this gap, this study proposes a cognition-driven analytical framework supported by spatial analysis for rural space gene extraction and transmission. The framework consists of five interrelated components: environmental cognition, spatial element identification, system coupling, space gene extraction, and transmission mechanisms. The Guanzhong Region in Northwest China is selected as a representative case to examine the multi-scale spatial structure of vernacular settlements. The results reveal three major findings. (1) The proposed framework effectively links physical spatial features with local perceptual structures, enabling the identification of key elements constituting rural space gene. (2) Three categories of representative space gene and seven core morphological and functional factors are extracted through the coupled analysis of nature–settlement systems. (3) Three adaptive transmission mechanisms—element replication and reinforcement, recombination of disrupted elements, and controlled adjustment of characteristic elements—are identified to support spatial renewal while maintaining local distinctiveness. This research contributes a structured, scalable, and replicable workflow for rural space gene analysis and enhances the application of cognitive principles in geospatial modeling. The findings provide methodological and practical support for rural revitalization, cultural landscape conservation, and vernacular settlement planning in inland agrarian regions undergoing rapid transformation.

Despite its status as a heritage model, Suzhou’s Pingjiang Historic Block suffers from a significant “conservation deficit”. The current study quantifies this decay and identifies its socio-economic drivers through a field survey of 517 traditional residences and a multivariate analysis of 188 resident households. The results reveal widespread degradation, including 32% roof damage and 55% unauthorized window replacements. Binary logistic regression identifies institutional status (hukou) as the decisive predictor of housing integrity (β = −0.544). Non-local migrants, trapped by tenure insecurity, exhibit significantly higher damage rates (53.5%). In contrast, local residents, driven by an “Aging Trap” and thermal comfort needs, are the primary drivers of adaptive window replacements (OR = 2.71). These findings indicate that current static policies are failing to address structural misalignments between preservation mandates and resident reality. The study advocates for a shift towards “Adaptive Integrity”, proposing tenure integration for migrants and technical retrofitting support for the aging local population to reconcile heritage protection with contemporary living needs.

Authorized Heritage Discourse (AHD) equates heritage value with visual and material purity, marginalizing resident-led changes as damage. This study examines “parasitic” additions to Beijing’s siheyuan—vernacular, externally attached modules used to meet modern living needs—as a critical site of negotiation. Combining spatial mapping of 48 cases, a resident survey (n = 185), and stakeholder interviews (n = 13) conducted between April 2023 and June 2025, we identify a fundamental discursive rupture: residents overwhelmingly justify adaptations on “living rights” grounds (support rate ≈ 76.3%), while professionals uphold aesthetic conservation. We theorize these interventions as a “subversive compromise,” preserving the historic shell while embedding modern functionality, thus co-producing a state of “negotiated authenticity.” While limited by non-probability sampling, the findings call for a governance shift from rigid form-based rules to performance- and rights-oriented pathways, including provisional permits and participatory review. The study underscores the need to reconcile visual integrity with dwelling rights to sustain living heritage. Full article

This study investigates the traditional life within Al-Gh’deer Market Square, which constitutes a fundamental component of the vernacular urban fabric of Sidi Okba’s old city from a sensorial perspective. This oasis, located in the southeast of Algeria, is currently severely degraded and requires urban and architectural preservation. However, the sensory experiences that once characterised traditional urban life have not yet been systematically explored. The aim of this study is to fill this gap by analysing the historical atmospheres depicted in various literary and iconographic sources created by French and European explorers who visited Algeria during the colonial period. This research highlights each component of the “Al-Gh’deer” market square, which had a sensory impact on writers and photographers during their visit to Sidi Okba. This impact is revealed through the different tangible and intangible signals generated by these components, which were then felt and described textually and/or visually by the travellers. To this end, the thematic content analysis is used as a research technique in order to analyse this textual corpus, whilst the image formatting and staging constitute the method used for the iconographic corpus study. The first method makes it possible to detect the most relayed ambiences by travellers. This is revealed by the identification and computation of the associated words and/or expressions within the considered textual corpus. The second technique consists of the extraction of the elements generating the physical signals that should create a sensory relationship with the people within the scene or looking at it. The identified ambiences among the two corpora are crossed in order to determine the most felt ones in the marketplace as well as the various components generating them. The outcomes of this research work would serve as a basis for revitalisation initiatives within the frame of socio-economic and cultural development projects. Full article

It is necessary to advance traditional village sustainability by exploring the cultural dynamics integrated into contemporary heritage conservation. Jiangnan is located in a typical culturally integrated region of China that encompasses diverse traditional village heritage with variable spatial forms, influenced by a plurality of unique vernacular morphologies. To address the paucity of samples from culturally integrated regions, the simplistic digital quantitative indices, and the problem of non-specific cultural qualitative analyses, this research established a cultural spatial morphology form clue (CSMFC) at three cultural dimensions: Chinese family clan culture; natural ecological culture; vernacular feng shui culture. We constructed an index system and village morphology database comprising five types of traditional villages in Jiangnan. This research proposed a situational research method (SRM) based on metamodern theory to oscillate between quantitative metrics and the qualitative cultural context of 500 villages. The results demonstrate that village spatial morphology exhibits stepwise digital differentiation aligned with cultural boundaries, dynamically revealing the evolving relationship between village culture and spatial morphology. The implementation of an SRM can accurately map cultural distinctions, enhancing the scientific rigor and efficiency of traditional village cultural research and sustainable heritage conservation.

This paper examines the complex connections between religious painting and vernacular narratives during the Ming dynasty through a case study of the Miaoshan story mural in the Vairochana Hall (Piludian 毗盧殿) of Guanyin Monastery (Guanyinsi 觀音寺) in Xinjin 新津, Sichuan (near Chengdu). This mural constitutes the earliest precisely dated surviving example (completed in 1468 and renovated in 1756) of pictorial representations of the Miaoshan story in China, the popular hagiography of Bodhisattva Guanyin that gained wide circulation in Buddhist communities during this period. Although this narrative painting has already attracted scholarly attention, many questions concerning its origins and meaning remain unresolved. Through a comparison with the earliest extant textual variants of the Baojuan of Xiangshan (香山寶卷, reprinted editions of 1772 and 1773), this paper demonstrates the distinctive features of the Xinjin mural. It further situates the mural within the broader history of visual representations of the Miaoshan story from the fifteenth and sixteenth centuries that survive in Sichuan and Beijing. This case study reveals the significant influence of vernacular narrative traditions on Buddhist art during the Ming dynasty, while also showing that the Xinjin mural represents an independent version of the Miaoshan narrative that was not preserved in later written sources.

This study presents an integrated intervention strategy for the adaptive reuse of vernacular architecture in a state of ruin, focusing on the fortified village of Moya (Cuenca, Spain). The proposal is framed within a rural revitalization program aimed at educational and cultural tourism uses, with the goal of reactivating abandoned built fabric through the incorporation of new functions that generate social value and contribute to territorial development. The proposed methodology combines archival research, digital documentation, material characterization, and a constructive solution based on the insertion of a reversible, structurally autonomous timber volume within the existing stone masonry. Through material characterization, a differentiated consolidation protocol is developed to stabilize the ruins while maintaining historical legibility. The new architectural volume, built with prefabricated cross-laminated timber (CLT) and insulated with locally sourced expanded cork, is designed to meet contemporary standards of energy efficiency, reversibility, and environmental responsibility, while remaining fully independent from the original structure. The intervention offers a replicable model for sustainable rural regeneration, balancing conservation ethics with functional adaptation. Future lines of research include the dynamic simulation of the energy performance of the inserted dwelling, with the aim of assessing its contribution to climate neutrality and net-zero emissions targets.

The narrow courtyard houses in the rural areas of Guanzhong region of Shaanxi Province, China, are a spatial representation of the long-term interaction of multiple influencing factors. This study, based on 716 questionnaires and 125 semi-structured interviews, comprehensively employed typology, qualitative analysis, comprehensive fuzzy evaluation, and grey correlation degree analysis methods to analyze the spatial evolution process of 125 typical samples since 1949. The results of research show: (1) In terms of spatial form, the narrow courtyard houses have evolved along a “from single to multiple, from horizontal to vertical, from open to closed” path. Their core has shifted from the symbolic “courtyard” to the functional “hall”, and the value of the main and auxiliary spaces has also undergone reconstruction, reflecting a modern transformation from “priority of etiquette” to “life quality orientation”. (2) The driving path starts from the institutional traction during the “survival stage”, then shifts to the economic dominance during the “growth stage”, and finally turns to the policy guidance and quality pursuit in the “life stage”, which are all coordinated. Policy and industrial structure are the core macro driving forces that run through the entire process. (3) Overall, the modernization transformation of the narrow courtyard houses is a dynamic process driven by external factors, with its path gradually shifting from the traditional endogenous model to external promotion and towards a diversified balance; however, the current “vacuum” state of cultural concepts reveals that the modernization of rural houses is still in the transitional stage between old and new paradigms. Based on this, the core of future rural house construction lies in achieving an internal reshaping from functional form to cultural value, guiding the spatial form to move from “disorderly exploration” to the organic generation of a “new paradigm”, providing a sustainable spatial paradigm for rural revitalization.

Inner courtyards have been traditionally used as passive strategy in vernacular buildings in desert climates. This paper presents a study conducted to investigate indoor and outdoor thermal comfort of two vernacular buildings in the hot arid climate of Upper Egypt and proposes an improved solution for courtyards to achieve sustainable development of current vernacular houses and apply the same in the arid climate zone of Egypt. The thermal comfort of vernacular building spaces was evaluated based on using field measurements during the hot season and improvement for courtyards based on ENVI-met V5.6.1 simulation model using three scenarios. Two vernacular buildings (Hassan Fathy and Nubian house) were selected to represent the traditional buildings south of Egypt. The study found that using adobe bricks with high thermal mass in vernacular buildings maintained lower indoor temperature with a range of 2.7 °C to 6.7 °C compared to outdoor temperature; this is considered effective thermal insulation. Meanwhile under extreme hot conditions, courtyard temperature inside the vernacular house was 0.3 K higher than the outdoor. This is not sufficient to maintain indoor thermal comfort without integrating passive solutions inside courtyards. In addition, applying the hybrid solution with big dense trees in the courtyards achieved a significant reduction in PET ranging from 4.2 °C and 5.7 °C; shading the widest area of courtyards and allowing for family activities. The study provided techniques and methodology for the middle courtyard of vernacular buildings, demonstrating how improvement achieves thermal comfort and sustainable development required in the 21st century in Upper Egypt, and can be applied to other vernacular houses in different desert cities in southern Egypt.

This study builds on a previously developed typo-morphological method used for the rural architecture of the “Capo Due Rami” area and tests its transferability to the northern sector of Sabaudia within the Pontine reclamation system. Beyond the historical, typological, and landscape dimensions explored earlier, this research adds a further analytical component focused on the relationship between settlement form and territorial planning. This extension represents the major methodological contribution of the study, allowing the repetitive structure of Opera Nazionale Combattenti farm units to be interpreted not only as a building system but also as an implicit territorial-planning device. The case study, located in the northern sector of Sabaudia, explores the relationships between the colonial settlements of the Opera Nazionale Combattenti (ONC), the agrarian framework, and the reclamation infrastructures, interpreting the repetition of settlement models as an implicit form of territorial planning. Using an integrated framework based on field surveys, archival materials, and multiscale cartographic analyses, the observation sheets show how architectural features, land-division schemes, and reclamation infrastructures are structurally interrelated. The results show that this new analytical dimension enhances the method’s interpretative capacity, highlighting the role of typological standardization in shaping the spatial and cultural structure of the reclaimed landscape. They reveal the morphological and functional consistency between architecture and landscape. Overall, the investigation confirms the coherence and replicability of the expanded approach. It shows that rural architecture is not only the material expression of a productive model but also an active agent in constructing and regulating the Pontine agrarian territory. Rural building emerges not only as the material outcome of a productive model but also as an active agent in shaping the agrarian territory. The research helps establish a comparative framework for interpreting Italian rural landscapes, supporting the valorization of vernacular heritage and reflection on the implicit planning principles embedded in typological architecture.

The main challenge for the scientific community is to mitigate climate change impacts while reducing energy consumption, without compromising comfort and quality of life. Buildings in hot climates require specific design strategies to limit the effects of extreme weather and heat waves. Standardized modern buildings, often unsuitable for hot and arid climates, lead to high energy consumption, mainly due to cooling systems, causing both discomfort and energy inefficiency. Previous studies have shown that solutions inspired by local vernacular architecture are often more effective than conventional construction techniques. This paper investigates the thermal response and discomfort intensity in two building models exposed to various climate scenarios: a typical modern residential building and a bioclimatic vernacular-inspired building. The analysis is conducted through dynamic thermal simulations under current as well as future medium- and long-term climate change scenarios. The study evaluates the buildings’ ability to adapt to future environmental changes, an aspect that has not yet been studied in depth. Results show that contemporary buildings experience significantly higher levels of thermal discomfort than vernacular buildings under both present (TMY) and future (SSP1-2.6 and SSP5-8.5, 2080) climate conditions. Results show that under the present climate, the vernacular building exhibits about 22% fewer discomfort hours than the contemporary one and roughly half the overheating integrated degree-hours. Under future scenarios, overheating increases by 25.8% to 67.7% in the contemporary building and 36.1% to 89.6% in the vernacular building, yet the vernacular building consistently maintains substantially lower discomfort levels. Overall, vernacular inspired envelopes remain more resilient to warming in all scenarios, but additional adaptation measures are required to ensure acceptable summer comfort by late century.

In the era of climate crisis, the search for places that offer natural climatic comfort has become a crucial element in understanding the interaction between the environment and the overall quality of human life. Although indoor artificial climate control can provide comfort, it has significant environmental impacts and fosters a more artificial human experience. This study explores how climatic comfort varies worldwide, with a particular focus on outdoor environments where natural atmospheric factors directly influence human perception of comfort. We conducted a global survey, integrated with spatial climate databases, to model outdoor climatic comfort based on temperature, humidity, and natural lighting. The most comfortable locations were identified in tropical/equatorial regions at relatively high elevations. We discuss the results of the current global population distribution, along with past, present, and future demographic scenarios, thereby revealing a critical situation for countries in the Sahel and Middle Eastern deserts.

High-altitude cold regions suffer from severe diurnal temperature fluctuations and limited energy supply, posing persistent challenges for maintaining indoor thermal comfort. This study investigates how the spatial configuration and thermal buffer effect can be optimized to improve the energy and comfort performance of new-type vernacular housing in Lhasa, China. Based on field-measured data, two representative housing prototypes—a self-built U-shaped dwelling and a government-designed resettlement house—were modeled and validated using EnergyPlus through the Rhino/Grasshopper platform. Parametric simulations and multi-objective optimization employing the NSGA-II algorithm were conducted to optimize both annual heating load and heating-season comfort percentage. Results show that optimized configurations combining south-facing sunspaces, north-facing enclosed corridors, and attic buffer cavities can reduce heating load by up to 80% compared with the baseline model without buffer spaces, and increase comfort duration by more than 50% under identical envelope and climatic conditions. The findings quantitatively reveal how spatial hierarchy and boundary buffering synergistically enhance passive solar utilization and thermal stability. This research establishes an integrated form–space–boundary optimization framework for energy-efficient housing design in extreme climates and provides a transferable reference for sustainable building strategies in other high-altitude regions.

This paper focuses on the image evolution of Shi Daoji (Ji Gong), a monk of the Southern Song Dynasty, and explores its important significance in the history of Chinese Buddhism. The historical authenticity of Dao Ji was once questioned, but the Epitaph written by Jujian, provides key evidence for his existence. It records Dao Ji’s origin, ordination, personality, and behavioral characteristics, establishing the prototype for later Ji Gong legends. Initially, Dao Ji existed as an “unconventional monk” with eccentric behaviors yet possessing spiritual legitimacy. During the Song-Yuan period, huaben (vernacular tales) and recorded sayings shaped him into a “San Sheng” (Uninhibited Sage), which conformed to the characteristics of Buddhism’s sinicization and gained widespread acceptance among the people. In the Ming and Qing dynasties, Dao Ji was further recognized as an “Arhat Yingzhen” (a realized Arhat), and his Chan lineage was gradually clarified in lamp records, with his status continuously elevated. The evolution of Dao Ji’s image reflects the process of Buddhism’s secularization and sinicization. It not only embodies the influence of folk beliefs on orthodox Buddhism but also reveals that Buddhism needs to integrate into people’s lives to complete its localization, providing a unique perspective for understanding the development of Chinese Buddhism.
