This paper addresses the special issue theme of the response of conservation practice to shifts in heritage theory towards the intangible, through exploring some specific aspects of practice and statutory process in the UK. The paper starts with an overview of conservation in the UK, and the extent to which it does or does not interface with developments in heritage theory. It explores the conventional understanding of significance—here termed ‘subtractive’—which reflects the antiquarian concerns from which conservation developed. It then considers the Ecclesiastical Exemption, a parallel consent mechanism within UK law for Christian places of worship that remain in use, which specifically recognises their need to change over time to ensure their survival. Evidence for a growing appreciation of non-tangible value and community participation in heritage is provided in recent research by The National Churches Trust into the economic and social value of church buildings to local communities across the UK. The paper concludes that a positive response to changes in heritage theory requires conservation to undertake its own theoretical work; this will involve a recognition of living buildings as central rather than peripheral both to conservation and to heritage more broadly, and a move towards a ‘generative’ understanding of significance.

Herat has a long and rich history of architecture and culture that has been shaped by many different historical and imperial periods. Since 2002, the city’s urban landscape has changed significantly due to a rapid rise in the city’s population and modern building processes. This has had a significant impact on the historical image and identity of Herat, as modern architecture has introduced identities that are not in harmony with the city’s environment, climate, and culture. This study conducts a comprehensive analysis of architectural identity characteristics to explore the role of traditional and modern architectural elements in forming Herat’s architectural identity. This research is based on primary and secondary sources including literature reviews, historical documents, case studies, and interviews with local architects and residents. The results indicate that Herat’s architectural identity is shaped by a multitude of factors, including its historical and cultural importance, the utilization of construction materials, the surrounding environmental conditions, architectural guidelines and expertise, political dynamics, and the preferences of both the architect and client. This study provides vital insights for architects, policy makers, and government agencies seeking to promote sustainable and culturally sensitive development in Herat’s dynamic architectural landscapes.

The stratified relationship and mutual influence between the representation of the project and the form of built architecture manifest above all in the facade design by virtue of its natural rhetorical vocation. This is the case of the Casa dei Filippini, designed by Francesco Borromini in the second quarter of the 17th century in Rome. The perspective niche in its façade appears to be a literal three-dimensional transcription of a graphic convention adopted in the presentation drawings. To understand the context and the reasons for this “translation”, this article historically frames the theme of the facade intended as a mask and its implicit representational qualities, which can configure it as an autonomous work from the building itself; it frames the interferences between architecture and its image in the era of the advent of pseudo-projective representation and the resistance it finds; it focuses on the facade of the Casa dei Filippini and its perspective niche, here surveyed and photo-modeled to determine the size and relationship between the actual and the perceived shape. Through these methodological and operational premises, the article reconstructs the original center of the façade deformation and analyzes the fictitious value of the facade, as testified by Borromini’s attempt to orient its perception through the drawings of his Opus Architectonicum and those derived from them, eventually confirming the two-way relationship between form and representation.

The preservation of historic structures is a complex and evolving field that requires a delicate balance between traditional methods and modern technology. This paper presents a conceptual framework for integrating terrestrial laser scanning (TLS) into the Historic American Buildings Survey (HABS), bridging the gap between the past and the future. By examining the historical context of the HABS and the emerging potential of TLS, the paper explores the feasibility, effectiveness, and methodological considerations for incorporating this advanced technology into the standard heritage building documentation practice. The research is structured into four main chapters, each addressing a critical aspect of the integration process, from the proposal of the study to the development of guidelines for TLS data acquisition, processing, and management. The paper also delves into the selection of projects for case studies, the application of the framework, and a critical evaluation of its effectiveness. As a conceptual paper, it lays the foundation for a Ph.D. dissertation, offering a comprehensive roadmap for future research and practical implementation. The insights and guidelines provided in this paper aim to enhance the accuracy, efficiency, and richness of heritage documentation, contributing to the broader field of heritage preservation and underscoring the importance of embracing technological advancements while honoring historical integrity.

In recent years, architectural interactions have become the center of many important reflections. However, there is little agreement on the subject. Some authors consider architecture to be about its relations with human and nonhuman agents. Others consider that buildings have an autonomous presence, which transcends all their interactions. These approaches are generally seen as incompatible. Although at the heart of the debate is the role of relations in architecture, their nature is not addressed. The discussion could gain clarity by recognizing the differences between them. In this paper, we propose a classification of architectural interactions, which may help to better inform further discussion on the topic. A closer look at architectural relations reveals that autonomy and relationality are not opposing, but complementary, aspects. Full article

This essay will discuss the evolution of writings about adaptive reuse. The architectural practice is as old as the buildings themselves, yet it has scarcely been discussed or even recognised until relatively recently. The essay will document the varied influences that informed the early publications (the first from 1976). The lack of easily available material (that is, books and documented buildings) meant that pioneering writers had to draw upon other sources—those beyond established architectural discussions. Therefore, these early authors were not limited by the strictures of an already established subject but were able to collate information from a variety of sources. Thus, adaptive reuse draws upon a collage of different sources, many beyond pure architecture, including installation art, fine art, curation, interior design, and urban design. Inevitably, as the subject moves from the periphery of architectural practice towards the middle ground, the number of publications has increased. This diversity has provided the subject with a greater scope, supporting the acknowledgement of the importance of technology, sustainability, and conservation in addition to ideas of heritage and culture, while also allowing for a much less Western-centric focus.

Blue–green infrastructure (BGI) has become a practical approach with emerging attention to addressing flood mitigation in many countries worldwide. The environmentally sound, sustainable approach of BGI has led it to gain scientific interest above other available mitigation techniques, such as grey infrastructure, soakaways, etc. This study was intended to conduct a thorough scoping review, followed by a bibliometric analysis, using the VOSViewer version 1.6.19, of the available flood mitigation techniques and the emergence and effectiveness of BGI as a strategy. The scoping review was based on 50+ recent (between 2013 and 2022) journal research papers. The study enabled the development of an elaborative idea about BGI and its applications in Australia, and it describes the trend of research to use BGI for flood mitigation. Following a comprehensive survey, it was established that BGI had been recognized as an effective measure in addressing unexpected floods, and it is indeed a beneficial project in the long term. It mitigates urban flooding, improves the environmental quality by purifying the urban atmosphere, and, further, includes the health and well-being of the community as co-benefits. However, although BGI has many environmental and other connected benefits, there are some restrictions that are decelerating the initiation of BGI as a project. Therefore, this application takes time and effort even before implementation. The bibliometric analysis of this study revealed that robust connectivity is seen in the global perspective between BGI, green infrastructure, and flood risk management, depicting a strong bond. In contrast, in the Australian context, an explicitly networked BGI specifically had yet to be seen, and only “green infrastructure” was used instead. However, the emergence of BGI for flood mitigation was recognized in 2015, while Australian research was likely initiated in 2016. There is less acceleration in Australian studies compared to the global scenario. BGI is a trending topic in scientific research, offering a vast variety of benefits to the country. Concluding, this study strongly suggests an immediate initiation of proper awareness and the development of relatable policies as two primary considerations to encourage the implementation of BGI, which is an effective strategy to address floods in Australia and create livable and healthy cities.

World Heritage tourism in China regulates conservation approaches employed across natural and built heritage sites. However, focusing on the revenue-generating potential of these sites sustains material authenticity and technical conservation methods. The outcome is a conflict between conservation and commercialization, where socio-cultural values are overshadowed by the process of museumization. Underpinned by critical heritage theory and a focus on intangible heritage, this research seeks to confront this conflict by examining the shifting conservation practice at the Humble Administrator’s Garden (HAG), a World Heritage Site and Classical Garden of Suzhou, China. A mixed-methodological approach explores the interplay between architecture and landscape within its heritage conservation process, utilizing archival research, semi-structured interviews with HAG Management, and visitor journals. The study shows how HAG’s heritage is shaped by visitors’ personal experiences and emotions alongside expert interpretations, resulting in the foregrounding of diverse narratives that contribute to a holistic sense of place. Within its politicized system, the safeguarding of intangible heritage requires constant negotiation among the municipality, the market, and emerging narrators. Attempts to reinterpret its former heritage buildings demonstrate a changing conservation discourse as the site transitions from an exclusive literati estate to a multivocal space of cultural encounter. The study illustrates how a focus on narrative representation unifies architecture and landscape, reimagining centuries of literati culture. This makes conceptual space for considering how conservation management can inform a more holistic narration of ‘place’ at similar World Heritage sites via the foregrounding of previously silent stakeholders.

This paper explores the role participatory methods play in understanding the social values of built heritage, including people’s sense of identity, belonging, and place. It is based on research in Scotland where, as in many other countries, there is an increasing emphasis on contemporary significance and public participation within domestic heritage management frameworks. The paper draws on the experiences and findings of a social values assessment for Cables Wynd House, a Brutalist block of flats in Edinburgh that was listed in 2017. Through the case study assessment, conducted over six months in 2019, Cables Wynd House is manifested as a multiplicity of connected realities, diverse experiences, and micro-locations. The participatory methods reveal interactions and tensions between the architectural design and aesthetics of the building and participants’ lived experiences and connections. The article argues that the mix of participatory methods provide different opportunities and ways of knowing, surfacing diversity, dissonance, and complexity. It highlights that participatory research is a collaborative process, requiring a flexible and responsive approach to methods. The paper concludes that participatory methods and collaborative approaches can provide nuanced and contextualised understandings of the social value of built heritage, which can complement but also diverge significantly from professional assessments of value. Wider adoption of these methods and the resulting understandings into the management and conservation of built heritage would support more people-centred, inclusive, and socially relevant forms of practice.

The energy consumption of air conditioning systems in large spaces is a concern due to inefficiencies caused by the high ceiling. This paper presents the Green aIr-distribution System (GIS) retrofitting technique as a solution to reduce energy consumption and optimize thermal comfort in a large Hong Kong sports center to achieve carbon neutrality. A comparison is made between the existing air distribution system with ceiling supply and return as baseline model and the GIS with occupied wall supply and ceiling return as retrofit models regarding ventilation performance, thermal comfort, and energy aspects. Computational fluid dynamics (CFD) is employed to analyze the average operative temperature, airspeed, and other thermal comfort parameters. The findings demonstrate that implementing the GIS in the large sports center allows for a 1.5 °C increase in the supply temperature without significantly compromising thermal comfort. The algorithm for developing GIS for the large space application is also discussed. Additionally, the GIS model exhibits notable improvements in ventilation factors, such as Local Mean Age (LMA), Local air change index (LACI), and Air Distribution Performance Index (ADPI), resulting in improved air quality and reduced energy use within the occupied space.

How can computational tools support the proposition of 15-minute cities? This paper examines the implementation of computer-aided approaches that support the analysis and proposition of urban areas where residents can access all their basic needs within a 15-minute walk, bike ride, or public transportation ride—the ultimate goal of a 15-minute city. Although this concept has gained significant attention as a sustainable and equitable urban development model, more efficient implementations require complex spatial and temporal analysis. At the same time, computational approaches such as those within the generative and parametric logic can utilize algorithms to create and test design solutions quickly and efficiently, allowing designers to address a variety of scenarios and options for producing more walkable, integrated, and resilient urban environments. Exploring a systematic review of the scientific literature (n = 244 peer-reviewed empirical studies) on Scopus and Web of Science databases, this paper synthesizes approaches to support the analysis and design of 15-minute cities, emphasizing the use of computer-aided techniques. The work contributes to developing a knowledge base on computational tools for 15-minute cities, highlighting their strengths, limitations, and potential for further development. Full article

This article presents a detailed study of the stately palace of the Villa Giusti-Puttini, a building that, over the centuries, has undergone repeated transformations since its construction in the first half of the 15th century. For the study of this palace, owned between the 15th and 17th centuries by one of the most important families in the city of Verona (Italy), the authors have followed a methodology covering indirect sources (documentary and bibliographical) as well as direct ones (the building and constructive techniques, architectural and decorative elements, murals, etc.). This study expands the information available on the building as well as expanding knowledge on the history of architecture of the Veneto villa as a defining architectural phenomenon in 16th- and 17th-century architecture whose extensive influence was still felt in the 19th century. The history compiled through this research also contributes to a renewed interpretation of the phenomenon, which is viewed as a process for the transformation and adaptation of a pre-existing building to fit the needs of any given period. This methodology, which could potentially facilitate the interpretation of similar buildings, and its combination of documentary, material, constructive, decorative, and cultural elements could constitute an example for the historical and architectural reading of buildings and are not merely limited to Renaissance buildings.

Adaptive Reuse of Historic Buildings (ARHB) is a new concept in developing countries like Sri Lanka. One of the main concerns for the intendancy of decision makers to ARHB is the operational energy. This paper analyzes the research gap of reusing historical buildings as office spaces by utilizing their structural and architectural designs and preserving the buildings’ authenticity for the future. It further aims to protect energy-efficient historical buildings from getting demolished and replaced with new modern buildings. A set of operational energy variables of modern office buildings and the potential historic buildings that can be reused as office spaces was established. During the early 1990s, old Dutch-era buildings in the country were mainly used as government office buildings. Three Dutch-era buildings in Galle Fort and three modern buildings in Colombo City have been selected as the case studies. Design-Builder (DB) software was used to comprehensively analyze sets of operational energy consumption variables. Selected historic buildings in Galle consumed 143.74 kWh/m², 156.34 kWh/m², and 209.39 kWh/m² while modern buildings consumed 337.29 kWh/m², 210.99 kWh/m², and 382.57 kWh/m² as operational energy, respectively. According to the analysis, the operational energy requirement of ARHB is comparatively lesser than that of modern buildings. This study, therefore, mainly concludes that the historical buildings saved more operational energy than the modern building envelopes while considerably reducing environmental impacts and saving the building energy cost.

This article has aimed to analyze the intellectual structure associated with the contributions made by academics and practitioners of architecture in the association between housing and COVID-19 in the years 2019–2021. The main results reveal the possibility of establishing a classification, by topics that suggest the necessary interdisciplinary collaboration for housing, to meet the needs and desires of its users in the wake of this pandemic. The network analysis has allowed the identification of overlapping communities through interconnection concepts to other groups or clusters. Thus, it has been possible to explore the multidimensionality of the housing–COVID connection and the interrelationships for future research and its possible extension. In this sense, the importance of the specific concepts associated with very detailed elements, sensations and spaces in buildings has been identified, including concepts such as the air quality and the need for green spaces, the presence or not of balconies, the need for natural light, the existence of cross ventilation or the possibility of incorporating technology or home automation to facilitate and save resources in daily life.

Green roofs are becoming popular in urban areas due to their potential benefits, including energy efficiency, urban heat island mitigation, and stormwater management. However, their water consumption can negatively impact water resources. Therefore, carefully managing the water consumption of green roofs is crucial to ensure they do not exacerbate existing water scarcity issues. This review explores the influencing factors and innovative solutions that increase the sustainability of water management on green roofs. A systematic quantitative review was conducted on published studies on green roofs. The review highlighted that while small-scale experimental studies are almost saturated, large-scale monitoring studies are still lacking. Modelling and assessing green roof settings based on climatic conditions and water availability and consumption are essential for successful water management. Using integrated technologies and sensing systems can increase water management efficiency and sustainability. Rainwater may be sufficient as a water source for green roofs in wet climates, while irrigation is still needed in other climates. Phytoremediation and biosorption can potentially increase runoff water quality. Improving hydrological performance by increasing rainwater retention and reducing water consumption capacity can reduce demand for other water resources and effectively manage small storms, mitigating pressure on city infrastructure and increasing water quality. Seeking non-potable sources, such as greywater, or harvesting enough rainwater to be used for irrigation during dry weather periods is highly advantageous for improving the sustainability of green roofs.

Moving to a new country is often combined with issues such as stress and a sense of loss that affect the overall well-being of immigrants. Furthermore, immigrants have not yet developed strong attachments to the country and, more specifically, to the places in which they will settle. Researchers have already discussed the role of the built environment for well-being and the sense of belonging and attachment it can provide, specifically through public open spaces, such as parks, squares, etc. These problems are worldwide, and the World Health Organization (WHO) also recommends creating public places that improve human health, well-being, and social inclusion. Moreover, at local levels, designers and urbanists must understand how to evaluate the relationship between immigrants’ place attachment and public places in order to improve the design of these places. Consequently, this study reviewed methods used to understand the effects of public open spaces on immigrants’ attachment. A systematic quantitative literature review was conducted, and a total of 26 articles were extracted relating to immigrants’ place attachment and public open spaces. Research locations, participants’ nationalities, the types of public open spaces, the methods applied, and place attachment evaluations were retrieved from the articles and analysed. The results show that evaluating immigrants’ place attachment presents many challenges, and there is no consensus on what approaches are best practices. However, qualitative methods were most applied in human–environment interactions, and immigrants’ place attachments were primarily assessed based on their social bonds in public open spaces. To conclude, a framework was designed to understand how immigrants’ place attachment was evaluated in the reviewed literature, and the dimensions of place attachment were defined. Full article

Artificial intelligence and machine learning, in particular, have made rapid advances in image processing. However, their incorporation into architectural design is still in its early stages compared to other disciplines. Therefore, this paper addresses the development of an integrated bottom–up digital design approach and describes a research framework for incorporating the deep convolutional generative adversarial network (GAN) for early stage design exploration and the generation of intricate and complex alternative facade designs for urban interiors. In this paper, a novel facade design is proposed using the architectural style, size, scale, and openings of two adjacent buildings as references to create a new building design in the same neighborhood for urban infill. This newly created building contains the outline, style and shape of the two main buildings. A 2D building design is generated as an image, where (1) neighboring buildings are imported as a reference using the cell phone and (2) iFACADE decodes their spatial neighborhood. It is illustrated that iFACADE will be useful for designers in the early design phase to create new facades in relation to existing buildings in a short time, saving time and energy. Moreover, building owners can use iFACADE to show their preferred architectural facade to their architects by mixing two building styles and creating a new building. Therefore, it is presented that iFACADE can become a communication platform in the early design phases between architects and builders. The initial results define a heuristic function for generating abstract facade elements and sufficiently illustrate the desired functionality of the prototype we developed. Full article

Majapahit was one of Indonesia’s most prominent and last Hindu kingdoms in the 12–15th centuries. During this time, there was a process of changing religious beliefs among the Javanese population, who then embraced Hinduism to eventually become Muslim. In the 14th and 15th centuries, according to estimates, Islam began to spread throughout the Majapahit Empire. There was also a cultural shift in the Majapahit Kingdom’s society, from how they dressed to the shape of their houses. This study aims to determine how structures from that time were interpreted using a 3D model based on field surveys and previous studies. This documentation’s findings are divided into typology, spatial distribution, and architectural elements. Each of these three groups was further defined through Islamic law to determine the extent of Islam’s Influence on dwellings throughout the Majapahit Era. The impact of Islam on Majapahit architecture during that time was characterised by openness in terms of building typology, compactness in the internal layout of buildings, and the employment of ornamental architectural features based on plant and abstract patterns.

As most people spend their days indoors, it is indeed important that buildings provide residents with a higher standard of health, convenience, and safety. As a result, many practices are implemented into buildings to improve the comfort of occupants, particularly thermal comfort; nevertheless, the energy required to run and maintain these applications is a significant constraint. Renewable energy sources offer alternative solutions to energy demand problems, and selecting the best renewable energy sources is crucial. In this article, we examine the health and well-being advantages to the occupants, as well as the surrounding environment, of a variety of novel strategies that may be integrated into buildings to increase occupants’ thermal comfort for conventional practices using solar power. The key discoveries explored in this article include daylighting, passive ventilation, thermal applications, cooling applications, and power generation. For this, the information was gathered by a systematic review of the relevant prior literature. In addition, the detrimental effects of existing practices on the health and well-being of residents and the environment are included. While there are still some practical obstacles to overcome in the extraction of solar energy, the technology exists. Potential future obstacles to the broad acceptance and usage of solar energy systems in buildings are highlighted, as well as possible solutions. Full article
