There is growing acceptance that heritage buildings are an important element of Australia's social capital and that heritage conservation provides economic, cultural and social benefits to urban communities. The decision whether to reuse a building entails a complex set of considerations including location, heritage, architectural assets, and market trends. The role of building conservation has changed from preservation to being part of a broader strategy for urban regeneration and sustainability. A growing body of opinion supports the view that adaptive reuse is a powerful strategy for handling this change. Urban development and subsequent redevelopment has a significant impact on the environment and the purpose of this paper is to investigate how the conservation of heritage buildings may contribute to a more sustainable urban environment.

This paper examines the views and experiences of architects, developers and building managers who have been involved with the adaptive reuse of heritage buildings. In total, 60 semi‐structured interviews were drawn from this stakeholder group to investigate their current understanding of the sustainability issues associated with the adaptive reuse of heritage buildings.

The subsequent data show that despite many positive outcomes in terms of sustainability, the adaptive reuse of heritage buildings is considered to create many problems; not the least of which is whether heritage buildings are icons that should be conserved or whether they are in fact eyesores and unviable for adaptive reuse.

The contribution of heritage buildings to the three tenets of sustainability has not previously been explored comprehensively and as a result there is a conflict of interest between the preservation of heritage values and progression of the sustainable urban design agenda.

Heritage buildings are a witness to previous civilizations and constitute important elements in transmitting cultural identity through generations. In 1938, Alexandria University was established; it was called the University of Farouk at the time. In 1952, the university was named “Alexandria University,” and since then, it has witnessed growth and expansion in several fields. The research aims to preserve the heritage of this academic institution. It seeks to document this wealth of buildings that tell the story of the second-earliest university in Egypt.

A mixed-method approach was employed. A descriptive method was used to narrate the history of the university and the importance of its buildings. Within the quantitative approach, a questionnaire was chosen as the survey instrument for collecting the data within the research case study. The aim was to determine the awareness of students, staff and employees of the heritage importance of their faculty. Within the qualitative approach, several interviews were conducted with employees in the engineering departments of the university administrative building at Chatby and some of the selected faculties. The aim was to determine the methods used for the conservation of these buildings.

Alexandria University has a heritage value not only in its great history but also through its heritage buildings. Raising the awarness of the university's affiliates of this heritage will lead to enhance the feelings of loyalty and belongings to the university. Therefore, preserving this heritage and properly managing it is crucial.

Universities have to recognize that their built heritage constitutes a unique expression that can create a distinctive sense of place. University heritage is crucial in defining and interpreting the university cultural identity. The institution must identify resources that will help build a new public image and contribute to develop a successful brand. Campus appearance is an important factor that has a significant impact on student feelings of loyalty and belonging.

Retrofitting and rehabilitation are part of the conservation approach in Heritage Building Conservation Guideline 2016 in Malaysia. Heritage buildings can be retrofitted to preserve their culture and history while being given a new lease. Rehabilitation is a preservation requirement that is more flexible since it assumes that the structure has already deteriorated to the point where repairs are required to prevent further deterioration. Although the strategies of these two approaches are different, their combination resulted in sustainable heritage building maintenance. This long-term maintenance strategy is necessary, especially for Malaysia's numerous heritage schools, which have serious maintenance problems as a result of infrequent maintenance, repairs, and funding shortages.

This study involved secondary data from an intensive literature review along with a comparative study from articles review and context analysis. A comparative study was conducted to determine the typical issue with heritage school buildings and the best maintenance practice for these structures. Finally, it involved a SWOT analysis study of retrofitting and rehabilitating heritage school buildings will be discussed in this study as well.

The findings of this study will focus on developing a strategic planning framework and maintenance for heritage school buildings in Malaysia to achieve sustainable maintenance. It will also highlight sustainable maintenance best practices for heritage school buildings in Malaysia. Finally, SWOT analysis will go over the pros and cons of retrofitting and rehabilitation for these buildings.

This paper put forward the requirements of strategic planning in heritage school buildings and outlines the significance of sustainable maintenance for educational buildings. It is an alternative for cost savings that has not been extensively investigated in previous studies.

This paper aims to investigate the theoretical and practical links between digital twin (DT) application in heritage facilities management (HFM) from a life cycle management perspective and to signpost the future development directions of DT in HFM.

This state-of-the-art review was conducted using a systematic literature review method. Inclusive and exclusive criteria were identified and used to retrieve relevant literature from renowned literature databases. Shortlisted publications were analysed using the VOSviewer software and then critically reviewed to reveal the status quo of research in the subject area.

The review results show that DT has been mainly adopted to support decision-making on conservation approach and method selection, performance monitoring and prediction, maintenance strategies design and development, and energy evaluation and management. Although many researchers attempted to develop DT models for part of a heritage building at component or system level and test the models using real-life cases, their works were constrained by availability of empirical data. Furthermore, data capture approaches, data acquisition methods and modelling with multi-source data are found to be the existing challenges of DT application in HFM.

In a broader sense, this study contributes to the field of engineering, construction and architectural management by providing an overview of how DT has been applied to support management activities throughout the building life cycle. For the HFM practice, a DT-cum-heritage building information modelling (HBIM) framework was developed to illustrate how DT can be integrated with HBIM to facilitate future DT application in HFM. The overall implication of this study is that it reveals the potential of heritage DT in facilitating HFM in the urban development context.

The purpose of the paper is to provide a comprehensive overview of the refurbishment of heritage buildings with special emphasis on sustainability and universal design. Findings of the study are the basis for further research and development of enhanced strategies for retrofitting and adaptive reuse of heritage buildings in the framework of sustainability and universal design.

The present research focusses on literature review analysis of specific elements of the refurbishment of heritage buildings with the aim to discover the characteristics/indicators of sustainability and universal design, which are usually used in refurbishment project and the gaps. In this paper, the latest state-of-art in the mentioned fields has been assessed, and the developments along with research gaps and potential future research focusses have been identified. The literature was collected mainly through Science Direct, World Wide Science and Emerald, especially focussed on publications from 2000 to 2019 written in English and the Web for regulatory and recommendation publications. Other sources, such as actual projects, might shed additional light on the specific issues of the studied topics.

This review shows that the current research related to heritage building renovation and reuse does not address sustainability and universal design issues comprehensively. Typically, in research, the topics of heritage, sustainability and inclusiveness are considered separately. In real situations, however, they are interconnected and influence each other, forming an indivisible whole. The needs of persons with disabilities (PWD) in correlation to the built heritage are not well studied. This is why it is important to consider these topics not only separately but also in an interrelated way.

The need for cross-disciplinary problem-solving method, based on a holistic approach, to form the base for implementation of universal design principles into refurbishing of heritage buildings is seen.

This paper demonstrates the need for usable procedures for various stakeholders in their everyday practice.

The combined subjects of sustainability, heritage buildings and universal design are not well covered by research. Lack of appropriate literature for this specific area is forming a significant gap that hinders the development of relevant information and methods that could be applied in actual projects. This paper, albeit in a partial way, intends to fill this gap and opts to provide a comprehensive summary of the sustainability factors affecting adaptive reuse of heritage buildings with special emphasis on users, specifically PWD.

Built heritage is a unique resource, an irreplaceable expression of the richness and diversity of our past and of the generations who have gone before us. Old Dhaka has an outstanding built heritage that is of significance not only in the local, but also in a national and regional context. But senseless urbanization and ignorance of such an important issue in the existing detailed area plan is destroying the built heritages of Dhaka. As a result, many heritage buildings of Dhaka have been destroyed and the destruction is going on unabated. Therefore, there is a need to re-examine how such destruction can be prevented. The paper aims to discuss these issues.

This research aims at the identification of heritages, their assessment and classification which is utterly significant for preserving the invaluable heritages. Heritages are classified according to their present condition which will show which type of heritage needs which type of attention.

The research indicates the way how a conservation planning for heritages can be done in a systematic and logical way. It reveals the present condition of the heritage buildings which will point out the way of preservation. There is no such document available which will tell general people about the most important or rare or significant heritages, the location of these heritages, or their background information. This research addresses these all issues.

To date, no conservation plans were implemented for Dhaka and there are no attempts to improve Old Dhaka through an urban design. The methodological approach in this research is new and effective for conserving heritages.

The purpose of this paper is to reveal the significant factors that contribute to the development of the assessment framework for wheelchair accessibility to National Heritage Buildings.

A qualitative approach was conducted via semi-structured interviews and go-along interview (Accessible Audit) through selected multiple case studies to reveal the main factors that contribute to the development of the assessment framework for wheelchair users in National Heritage Buildings in Malaysia. There are four National Heritage Buildings (gazetted under National Heritage Act, 2005) selected for this research.

The findings revealed a few significant factors comprising the physical built environment, organizational behavior and structure, financial resources, and existing legislation.

This research is limited to wheelchair users and National Heritage Buildings, which was conducted through semi-structured interviews and go-along interview (Accessible Audit).

This research investigates the standpoints of both the National Heritage Building operators and the wheelchair users pertaining to accessibility in National Heritage Buildings with regard to their respective roles as management and users.

The research demonstrates the importance of social participation effects on the accessibility in National Heritage Buildings based on empirical evidence in highlighting operators’ and wheelchair users’ challenges toward enhancing their accessibility.

This research will be a great contribution to the development of the assessment framework for wheelchair accessibility in National Heritage Buildings in Malaysia, including accessibility for pushchair, elderly, and pregnant women.

This paper presents a conceptual design process for developing a maintenance-focused heritage conservation model. Currently, there are several intervention approaches that can be applied in conservation from reconstruction, restoration and repairs to a “do-nothing” approach. This paper examines whether a maintenance solution is more than just an option or a necessity. The aim of the paper is to study the challenges and opportunities when putting more emphasis on the maintenance approach in conservation.

This research was conducted in an Australian context, where many major buildings were constructed from the 19th and 20th centuries and are now categorised as “modern heritage”. three case studies were undertaken to inform this paper and others. In addition, 17 global heritage conservation experts were interviewed, and their responses were analysed. Also, comparative field observations and archival records were examined and used to develop the initial framework model. Finally, using focus group discussions amongst 7 experts, the framework was reviewed and formally validated in order to ensure the development of a useful model for use in devising an effective maintenance management plan and monitoring conditions in heritage buildings.

This paper supports others in a series that have already been accepted by this journal, focussing the research on heritage building conservation being conducted in Australia, the homeland of the Burra Charter. The other papers are entitled (1) model for the maintenance-focused heritage building conservation and (2) engineering in heritage conservation.

The paper examines contemporary issues in heritage building maintenance and conservation in Australia and focusses specifically on the lack of focus on maintenance as a conservation intervention for heritage buildings.

Heritage buildings are significant for their historical and architectural value. Due to the lack of rating systems designed specifically for heritage buildings, it is essential to develop and validate a heritage building assessment tool that considers its specific characteristics. The purpose of this study is to provide an extensive review of research on Sustainability of Heritage Buildings (SHBs).

This review highlights methodologies applied in SHBs research and analyzes major global rating systems in order to identify their deficiencies for SHBs assessment. A systematic review was employed and articles from the top 10 high impact factor journals were studied. Twelve major global rating systems and their assessment criteria were identified.

Significant variability was observed among the assessment tools since each tool assesses several criteria, factors and indicators that fit its local context. Part of this variability can also be seen in the rating scales, threshold values and accreditation titles. As a result, the final sustainability ranking for a given building cannot be compared among the 12 rating systems. Most importantly, these systems fail to analyze some factors such as energy that are considered important with respect to heritage building assessment.

Since no specific rating system could be identified in this review as the most appropriate for heritage buildings, a new sustainability assessment tool that is specific to heritage buildings should be developed. Such a tool will enable facility managers to evaluate and improve the sustainability of their heritage buildings while preserving them.

Heritage tourism has become increasingly popular, and improving the sustainability of such sites is essential both nationally and internationally. The purpose of this paper is to explore the opportunities and challenges of improving the condition and sustainability of a chapel at a busy international heritage tourist attraction.

A case study approach was adopted. This utilised interviews with four of the primary building professionals involved with the refurbishment project. Documentary analysis and observations were also used.

The present case study presents the opportunities and challenges faced by a tourist heritage attraction. Improvements to the condition and sustainability of such assets are essential to ensure their sustained and enhanced use, and the protection of heritage buildings. Such projects create opportunities to increase knowledge and understanding about these assets as well as enhancing opportunities for meaning making for visitors. The paper highlights the importance of a strong leader and a balanced team working towards common objectives. Further, whilst synergies between conservation and sustainability exist, there are also tensions and compromises.

This case study highlights the opportunities and challenges of improving the condition and sustainability of built cultural heritage at a tourist attraction. Opportunities included increased knowledge and understanding about the heritage asset; enhancement of values for present and future generations; improved condition, increased usability; and increased sustainability. Challenges were: team turnover; delays resulting from archaeological findings; previous work resulting in building defects; the existing building condition; and unfamiliarity and the uncertainty regarding particular measures.

The practical implications of this case study include ensuring clear project objectives and a balanced project team are in place. These should be enhanced by a good system of information recording throughout the project to limit the impact of staff absence. Good communication within the team and with external members such as manufacturers will reduce the impact of unfamiliar products and aid in decision making. Future research should explore whether these findings are applicable to other heritage tourist attractions, and whether visitors’ narrative encounters with the asset change following a sustainability improvement project.

Limited research has been previously performed on improving the sustainability of built cultural heritage at tourist attractions. This research investigates the opportunities and challenges facing building professionals in improving such heritage assets. The improvement of heritage tourist attractions requires careful consideration. Whilst they need to be conserved for future generations, increasing the sustainability of such assets is essential to ensure their continued usability.
