PurposeAdaptability is an inherent quality in building circularity, as adaptability can physically facilitate the reversibility of materials in a closed-reversible chain, also called “loops”. Nevertheless, positioning adaptability in circularity-oriented models could overlook some of the contextual considerations that contribute to the utility for the built environment. This paper reconceptualises building adaptability to incorporate circularity, in order to facilitate for the resource loops whilst preserving the long-lasting functionality in buildings.Design/methodology/approachAn integrative literature review on adaptability and circularity of buildings was conducted using systematic search approach. From the initial database of 4631 publications, 104 publications were included for the final analysis. A comparative analysis of definitions and determinants of both concepts was conducted to reconceptualise circular building adaptability.FindingsThe findings of the literature study show that incorporating circularity and adaptability is possible through 10 design and operation determinants, namely configuration flexibility, product dismantlability, asset multi-usability, design regularity, functional convertibility, material reversibility, building maintainability, resource recovery, volume scalability, and asset refit-ability. The study concludes that considering the defined determinants in a holistic manner could simultaneously facilitate: building resilience to contextual changes, creation of asset value, and elimination of waste generation.Originality/valueThis paper expands the relevant bodies of literature by providing a novel way of perceiving building adaptability, incorporating circularity. The practical value of this paper lies in the discussion of potential strategies that can be proactively or reactively employed to operationalise circular building adaptability.
Purpose The application of circular building adaptability (CBA) in adaptive reuse becomes an effective action for resource efficiency, long-lasting usability of the built environment and the sped-up transition to a circular economy (CE). This paper aims to explore to which extent CBA-related strategies are applied in adaptive reuse projects, considering enablers and obstacles. Design/methodology/approach A stepwise theory-practice-oriented approach was followed. Multiple-case studies of five circular adaptive reuse projects in The Netherlands were investigated, using archival research and in-depth interviews. A cross-case analysis of the findings was deductively conducted, to find and replicate common patterns. Findings The study revealed that configuration flexibility, product dismantlability and material reversibility were applied across the case studies, whereas functional convertibility and building maintainability were less applied. Low cost of material reuse, collaboration among team members and organisational motivation were frequently observed enabling factors. Lack of information, technical complexities, lack of circularity expertise and infeasibility of innovative circular solutions were frequently observed obstacles to applying CBA. Practical implications This paper provides practitioners with a set of CBA strategies that have been applied in the real world, facilitating the application of CBA in future adaptive reuse projects. Moreover, this set of strategies provides policymakers with tools for developing supportive regulations or amending existing regulations for facilitating CE through adaptive reuse. Originality/value This study provides empirical evidence on the application of CBA in different real-life contexts. It provides scholars and practitioners with a starting point for further developing guiding or decision-making tools for CBA in adaptive reuse.
Adaptive reuse of buildings is the process of renovating, or rehabilitating existing buildings, or structures to fulfill a use other than their current use [1]. Adaptive reuse of buildings can provide economic, social and environmental benefits to societies. The economic benefits can be achieved through reductions in the time and cost of realizing functional buildings [2]. Rehabilitated buildings can be configured quickly, in comparison to constructing new buildings, provided that their structural systems are adequate [3]. Additionally, rehabilitated buildings would cost less than new construction, since many of the building elements already exist [4]. The social benefits can be achieved by preserving historical buildings, which could be in advantageous locations [5]. The environmental benefits can be achieved through the reuse of the utilities and materials, including water, gas, and power systems, hence, reducing the demand to provide new utilities, as well as the amount of embodied energy produced through the manufacturing processes of construction materials [3]. Nevertheless, adaptively reused buildings could provide several building performance concerns for their users [6]. These concerns range from the lack of effec
The buildings and construction sector accounts for the majority of the energy consumption in the Kingdom of Saudi Arabia (KSA). For a sustainable future, energy consumption in the sector should be reduced and existing buildings need to be energy retrofitted. A number of studies present energy retrofitting of residential buildings in KSA; however, there is a lack of studies presenting retrofitting of educational buildings. Thus, the aim of this study is to adopt a BIM-based approach to assess Energy Conservation Measures (ECMs) in a prototypical Government-built educational building in Dammam, KSA. The methodology consists of six prime steps, (1) case study data collection, (2) energy auditing, (3) proposing ECMs, (4) BIM model development, (5) energy assessment, and (6) economic assessment. The energy audit revealed several inefficiencies in the building construction and operation and four ECMs were proposed and simulated. It was found that annual energy consumption can be reduced by 22.7% in the educational building, and the investment for the four ECMs is paid back in 2.7 years only. Therefore, implementing the proposed ECMs is a viable option to energy retrofit such educational buildings in the country, and the presented BIM-based approach can be adopted to efficiently conduct the energy retrofitting process.
PurposeThis paper intends to review and assess the factors influencing adaptive reuse of commercial projects, throughout their life cycle, in Saudi Arabia.Design/methodology/approachA mixed approach of literature review, pilot-testing and questionnaire survey was utilized to identify and assess the factors affecting adaptive reuse of commercial projects. Thirty-eight factors were identified and categorized under four groups, corresponding to the key phases of the project life cycle. The questionnaire survey was administered to a targeted group of 90 architecture/engineering, construction and facilities management (AEC/FM) practitioners of building adaptive reuse, in the Eastern Province of Saudi Arabia. The relative importance index (RII) for each factor was calculated. Three levels of agreement, based on the ranking of the factors, among the respondents were determined.FindingsThe most important factors affecting adaptive reuse of commercial projects are: structural integrity of the building, municipal approval for the land use change, enforcement of safety procedures at the project site, compliance with health and safety measures and accuracy and completeness of the contract documents. A high level of agreement was observed among the three groups of respondents, on the ranking of the factors.Originality/valueThis research expands the body of knowledge, through providing AEC/FM practitioners, with the type, importance and ranking of the influential factors on adaptive reuse of commercial projects, throughout their life cycle.
In light of the spread of residential fires worldwide, this paper aims to identify the current fire safety code requirements for providing the minimum level of safety in residential facilities, hence, mitigating the risk of fire occurrence. The paper also presents the findings of a case study to demonstrate the compliance level of a sample residential facility, with code requirements. The case study building is composed of three floors and a basement. It can accommodate 214 persons. It was built in 2013, and it is located in Khobar, Saudi Arabia. The study revealed that the assessed facility had an adequate distribution of fire detection and notification systems. Moreover, the level of the housekeeping practices and concentration of hazardous material was found to be acceptable. However, the means of egress, fire doors and fire suppression systems were not up to code requirements. The study recommended measures to improve the level of safety in the building. These include increasing the number of fire exits; installing sprinkler heads on each floor; distributing fire extinguishers sufficiently; and installing fire rated doors. This study aims at raising awareness about the incidences of fires accidents in residential facilities and their catastrophic implications. It serves to provide a standardized fire safety management checklist, for the use of design professionals and property managers, towards the effective design and maintenance of residential facilities.
Schools are high-risk type of facilities in fire emergencies. This requires the implementation of safety measures, which comprise administrative and operational efforts to mitigate the occurrence of fire accidents. The review of literature indicated the lack of practical approaches that can be easily adopted for safety management in school facilities. This paper presents the development and implementation of a generic framework for fire safety management in school facilities. A literature review in the domain of fire safety in schools was performed to comprehend various knowledge areas in this context. A generic framework for fire safety management in school facilities was developed. The framework was implemented in a secondary school, located in the Eastern Province of Saudi Arabia, as a case study, to illustrate its applicability. An action plan was developed to improve the level of fire safety in the school facility, under review. The findings indicated that the framework provides a methodological and systematic approach for assessing the level of fire safety in schools, as well as determine the possible actions for improving the overall safety condition in such facilities. The paper provides a useful focus for practitioners and researchers concerned with fire safety in the educational workplace.
Purpose This paper aims to present a generic lifecycle framework model for guiding architects, engineers, contractors and facilities managers (AEC/FM) practitioners on the effective implementation of adaptive reuse projects. Design/methodology/approach A mixed approach of qualitative and quantitative techniques was followed in the development of the framework model. A literature review was conducted to comprehend the processes involved in adaptive reuse projects. In total, 90 AEC/FM practitioners were surveyed to identify the current practices in these projects. A generic framework model was then developed to standardize the processes involved, using integration definition for function modeling process modeling methodology. Face-to-face interviews with a targeted group of 30 AEC/FM practitioners were conducted, to validate the developed framework model, by assessing the importance and the frequency of implementing each function in the developed framework model. Findings The framework model consisted of four sequential processes, namely, assess the feasibility of the adaptive reuse project, design the adaptive reuse project, construct the adaptive reuse project and operate and maintain the adaptive reuse project. The validation confirmed the importance of all the framework functions and the frequency of their implementation. Originality/value This research contributes to the literature and the AEC/FM professions, through developing a lifecycle and knowledge-oriented framework model for building adaptive reuse. The framework presents clear documentation of adaptive reuse processes. Thus, it holds the potential of endeavoring on adaptive reuse projects to be more efficient.
