Abstract
Purpose
The purpose of this study is to minimize cost and minimize building condition. Weibull distribution approach was employed to generate deterioration curves over time. The third floor of Concordia University’s Engineering And Visual Arts (EV) Complex in Montreal, Canada, served as a case study to test the maintenance model and determine the optimal maintenance activities to be performed.
Design/methodology/approach
This research has demonstrated that there is insufficient fund allocation for the maintenance of non-residential buildings. Therefore, this research focused on designing and developing a maintenance optimization model that provides the type of spaces (architectural system) in a building. Sensitivity analysis was used to calculate weights to validate the model. Particle swarm optimization, based explicitly on multiple objectives, was applied for the optimization problem using MATLAB.
Findings
Following 100 iterations, 13 non-dominant solutions were generated. Not only was the overall maintenance cost minimized, but the condition of the building was also maximized. Moreover, the condition prediction model demonstrated that the window system type has the most rapid deterioration in educational buildings.
Originality/value
The model is flexible and can be modified by facility managers to align with the required codes or standards.

Abstract
Purpose
The research intends to investigate the different typological and morphological characteristics of the neighbourhood spaces produced by different urban dynamics since the late nineteenth century in Turkey.
Design/methodology/approach
The main problem that drives the research is that a significant increase in the construction of gated communities has started to be seen in the last five years as a solution to safety issues in Turkey. However, these gated communities as safe-spaces have resulted in the danger of destroying neighbourhood life's physical and social dynamics by changing their spatial configuration. The study offers an analytical framework structured from defensible space theory and other safe-space theories in the literature. It has analysed the effect of physical characteristics of urban fabric on the production of safe-space in neighbourhoods through mappings and site observations. The case studies are conducted in three different morphological periods in Turkey, which are the Seyrancik neighbourhood in Bolu (the Ottoman Period), the Subayevleri neighbourhood in Ankara (the Republican Period) and the Karaman neighbourhood in Sakarya (the Liberalisation Period).
Findings
The analysis concludes that any type does not come to the fore in the production of defensible space in terms of its spatial features, but each has various strengths and weaknesses. As a result, this study emphasises the role of design in providing defensible neighbourhoods in the case of Turkey's cities and reveals the aspects that will guide the design of an urban and housing form in terms of the safety–environment relationship in Turkey.
Originality/value
The significance of the study is the comparative analytical approach to studying the housing development and demonstrates a method for analysing safety issues in the transformation process of neighbourhood structures in Turkey.

Abstract
Purpose
In this study, a novel framework based on deep learning models is presented to assess energy and environmental performance of a given building space layout, facilitating the decision-making process at the early-stage design.
Design/methodology/approach
A methodology using an image-based deep learning model called pix2pix is proposed to predict the overall daylight, energy and ventilation performance of a given residential building space layout. The proposed methodology is then evaluated by being applied to 300 sample apartment units in Tehran, Iran. Four pix2pix models were trained to predict illuminance, spatial daylight autonomy (sDA), primary energy intensity and ventilation maps. The simulation results were considered ground truth.
Findings
The results showed an average structural similarity index measure (SSIM) of 0.86 and 0.81 for the predicted illuminance and sDA maps, respectively, and an average score of 88% for the predicted primary energy intensity and ventilation representative maps, each of which is outputted within three seconds.
Originality/value
The proposed framework in this study helps upskilling the design professionals involved with the architecture, engineering and construction (AEC) industry through engaging artificial intelligence in human–computer interactions. The specific novelties of this research are: first, evaluating indoor environmental metrics (daylight and ventilation) alongside the energy performance of space layouts using pix2pix model, second, widening the assessment scope to a group of spaces forming an apartment layout at five different floors and third, incorporating the impact of building context on the intended objectives.

Abstract
Purpose
This paper aims to identify user-centred facilities performance attributes of higher education buildings and how they can be used to evaluate individual learning spaces. These attributes are then consolidated for developing a post-occupancy evaluation (POE) framework in this context.
Design/methodology/approach
A systematic review of the literature on the POE of higher education buildings is conducted.
Findings
This study identifies 36 facility performance attributes in higher education buildings, which can be categorised into four dimensions: ambient; spatial; technology; and building support and services requirements. These facility performance attributes need to meet user requirements to achieve satisfactory feedback. It is also important to note that user requirements differ from one learning space to another; thus, it is essential to consider the characteristics of individual learning spaces.
Research limitations/implications
The proposed evaluation framework is context-based and may not be suitable to evaluate other types of buildings. It may be further extended and enhanced to meet other facility management evaluation needs.
Practical implications
The POE framework developed in this research can be used to generate facilities management analytic to inform future design and improve existing higher education facilities.
Originality/value
This research has developed a holistic POE framework tool to meet user requirements in higher education buildings.

Abstract
Purpose
Comfortable outdoor workspaces are important for employees in business parks and urban areas. Prioritizing a pleasant thermal environment is essential for employee productivity, as well as the improvement of outdoor spaces between office buildings to enhance social activities and quality of outdoor workplaces in a hot arid climate has been subjected to very little studies Thus, this study focuses on business parks (BPs) landscape elements. The objective of this study is to enhance the user's thermal comfort in the work environment, especially in the outdoors attached to the administrative and office buildings such as the BPs.
Design/methodology/approach
This research follows Four-phases methodology. Phase 1 is the investigation of the literature review including the Concept and consideration of BP urban planning, Achieving outdoor thermal comfort (OTC) and shading elements analysis. Phase 2 is the case study initial analysis targeting for prioritizing zones for shading involves three main methods: social assessment, geometrical assessment and environmental assessment. Phase 3 entails selecting shading elements that are suitable for the zones requiring shading parametrize the selected shading elements. Phase 4 focuses on the optimization of OTC through shading arrangements for the prioritized zones.
Findings
Shading design is a multidimensional process that requires consideration of various factors, including social aspects, environmental impact and structural integrity. Shading elements in urban areas play a crucial role in mitigating heat stress by effectively shielding surfaces from solar radiation. The integration of parametric design and computational optimization techniques enhances the shading design process by generating a wide range of alternative solutions.
Research limitations/implications
While conducting this research, it is important to acknowledge certain limitations that may affect the generalizability and scope of the findings. One significant limitation lies in the use of the shade audit method as a tool to prioritize zones for shading. Although the shade audit approach offers practical benefits for designers compared to using questionnaires, it may have its own inherent biases or may not capture the full complexity of human preferences and needs.
Originality/value
Few studies have focused on optimizing the type and location of devices that shade outdoor spaces. As a result, there is no consensus on the workflow that should regulate the design of outdoor shading installations in terms of microclimate and human thermal comfort, therefore testing parametric shading scenarios for open spaces between office buildings to increase the benefit of the outer environment is very important. The study synthesizes OTC strategies by filling the research gap through the implementation of a proper workflow that utilizes parametric thermal comfort.

Abstract
Purpose
The purpose of this paper is to describe challenges and lessons learned in the design and development of a comprehensive, flexible environmental management system (EMS) in a real university setting; also to inform development of similar systems elsewhere and provide a modular, extensible software architecture for such efforts.
Design/methodology/approach
A modular, flexible software architecture was designed as the cornerstone of a comprehensive, secure web‐based data collection and analysis framework. Environmental data such as utility usages, waste generation and transportation services were identified, collected, and entered into the evolving system. The system is easily extensible to new environmental data types, and supported manual and automated data entry, custom “at‐the‐source data entry” mechanisms, and flexible tools for visually analyzing environmental data captured.
Findings
Development of automated EMS systems for large institutions is significantly complicated by profound heterogeneity in campus infrastructure, management policies, and limited data accessibility; legacy data are often incomplete or inaccurate. Successful EMS initiatives must explicitly address these challenges through realistic project planning, choice of software technologies, design of system architecture, and administrative commitment. Detailed insights in each of the above areas are provided.
Originality/value
The authors provide clarifying discussion of sustainability plans versus monitoring systems, place popular technological gadgets such as live building energy monitors into perspective within this framework, and describe design and implementation of a comprehensive environmental monitoring framework. The modular concept for system architecture, design approach, and lessons learned can inform the development of similar comprehensive EMS development efforts.

Abstract
Renovation philosophy and residential construction mode are key problems encountered in the renovation of urban villages in China. Existing research fruits on renovation philosophy, and policies consider fairness and efficiency and cover-sharing research consensus. However, research on residential construction mode in renovation still faces challenges, such as weak relevant policy pertinence, insufficient objective references, and poor universality. In this study, the changes of the architectural spaces of a typical urban village community in Xi'an City from the beginning to the end of the renovation were discussed. The space requirements of different user groups were analyzed and summarized, and then adapted to the different types of building spaces. In addition, the residential construction model applicable to the inclusive renovation philosophy was established. Research results corroborated that the renovation of urban village should refer to its functional orientations in the community. The community-centered renovation residential district should also meet the requirements of different user groups in the community, including residential, living, and entertainment functions. Community-subcentered residential district should meet the space demands of residential and living functions. Community-subordinated residential district meets space demands of internal residents for residential and living. Moreover, residential district space is relieved by combining practical and certain spatial factors. In this research, the building space compositions of different user groups were reviewed and refined in the “bottom-up” pattern. Research conclusions provide design references for the practical renovation of urban villages.

Abstract
Purpose
The purpose of this paper is to present outcomes from a post-occupancy evaluation (POE) of a sustainable university building development.
Design/methodology/approach
A POE was conducted for a sustainable university building in Melbourne, Australia. The method included interviews with key stakeholders involved in the design, construction and occupation of the building. The interviews were complemented by conducting a Builder User Satisfaction survey and analysis of two year’s worth of building performance data.
Findings
While technically the building saw a significant improvement in performance in comparison to existing buildings at the university, it ultimately did not meet its design performance goals as determined by the design rating. The interviews revealed limited formal documenting of lessons learnt and the challenges associated with using a sustainable and innovative building to drive cultural change. A major success was the realisation by the university of the benefits that the systematic POE provided. Lessons are now being applied to other new and refurbished buildings on campus, with POE now an integrated part of these processes.
Originality/value
While there are some studies of sustainable university operations and buildings, many focus on one or two parts of the process and fail to include evaluation of the full sustainability approach to check if stated goals have been met. This paper begins to address this gap. Learnings from the research are applicable to the wider building development industry and demonstrate the important role universities can play in shaping the sustainability of urban environments.

Abstract
Purpose
The purpose of this research is to identify quick, effective and affordable architectural design solutions to improve the health of patients, visitors and staff, in an underfunded community healthcare center (CHC) in Baltimore.
Design/methodology/approach
Both qualitative (individual and Focus group interviews) and quantitative methods (space syntax analysis and questionnaire survey) are used to assess the healing environment. The questionnaires cover interior and exterior environment related questions.
Findings
The questionnaire identifies three issues related to wayfinding, interior design, and access to natural light. The findings demonstrate that the waiting area, exam room and laboratory need to be upgraded. Incorporation of some other interior components including, wall art, plants, music, signage are also suggested by the respondents.
Originality/value
Very few studies in the USA have been done to understand the effects of architectural design to create a healing environment on the community scale.

Abstract
Purpose
Exposure to poor indoor air in refurbished buildings is a matter of health concern due to the growing concentrations of various contaminants as a result of building airtightness without amendment of ventilation, or the use of building materials such as glue, paint, thinner and varnishes. Recent studies have been conducted to measure indoor air pollutants and assess the health risks affecting the quality of life, productivity and well-being of human beings. However, limited review studies have been recently conducted to provide an overview of the state of knowledge. This study aims to conduct a scoping review of indoor air quality (IAQ) in the context of refurbished or energy-retrofitted buildings.
Design/methodology/approach
A systematic screening process based on the PRISMA protocol was followed to extract relevant articles. Web of Science, Scopus, Google Scholar and PubMed were searched using customised search formulas. Among 276 potentially relevant records, 38 studies were included in the final review covering a period from 2015 to 2022.
Findings
Researchers mapped out the measured compounds in the selected studies and found that carbon dioxide (CO2) (11%) and total volatile organic compounds (11%) were among the most commonly measured contaminants. Two trends of research were found including (1) the impact of ventilative properties on IAQ and (2) the impact of introducing building materials on IAQ.
Originality/value
The contribution of this study lies in summarising evidence on IAQ measurements in refurbished buildings, discussing recent advancements, revealing significant gaps and limitations, identifying the trends of research and drawing conclusions regarding future research directions on the topic.
