Abstract and Figures

Accommodating populations in cities became increasingly a complex task. With the mounting local and global migration seeking better opportunities in cities, the current urban agendas has put forward compact cities as a promising solution towards sustainable urban development. Roof stacking is considered an approach towards increasing cities’ density. However, the selection of optimum roof stacking construction method is merely based on subjective evidence based on architects’ or owners requirements. There is an urgent need to identify sustainable indicators for decision making for roof stacking. Therefore, this research aimed to identify the influential criteria behind the selection and decision making on roof stacking methods. An intensive review of literature, individual interview, and pilot surveys have been carried out. A list of 37 sustainable indicators have been identified based on sustainability triple bottom line, i.e. environmental, economic, and social. A questionnaire has been design and distributed to architects and building engineers as active stakeholders. The importance of the identified indicators have been categorized and ranked. The outcomes of this research draws the line to develop a new tool that facilitates the construction of sustainable roofs in European cities.

... Alternatives could be compared based on any suitable criteria. When comparing alternatives based on the considered criteria the factors affecting material selection are initially identified through a literature review, and then the factors are finalized with the aid of surveys, expert opinions, or semi-structured interviews [31][32][33][34] where the Relative Index or Severity Index is computed to evaluate the level of importance of the alternative. Furthermore, the weightage of the impact caused by the parameters, the comparison of alternative materials, and the selection of the best material are carried out using the MCDM method [31,33]. ...

All over the world, sustainability has been given immense attention, thus novel state-of-the-art materials and building systems are emerging as alternatives. With those different alternatives, comparison and the selection of a better-performing material or a building system using diverse perspectives becomes important. Literature shows its complexity in adopting social and cultural dimensions in decision-making that adversely impacted on most desirable material selections in tropical underdeveloped countries as well as indigenous communities. This study proposed an eco-design-based material selection approach that considers the individual and holistic perspective of diverse eco-design indicators such as economic, ecological, social, and cultural. Several sub-themes are identified under each theme and are verified through expert surveys. The identified sub-themes are verified and compared Pairwise through expert surveys and using the Analytical Hierarchy Process leads to proposing weights for each theme and sub-theme and developing an eco-design-based material selection framework. Accordingly, saving energy (10.7%), reducing the overexploitation of natural resources (9.1%),reducing energy emissions (7.9%), and reducing construction (7.3%), as well as operational cost (7.6%), are the parameters that create a greater impact on the selection of sustainable material with the aid of eco-design. Overall, the ecological theme creates the highest impact of around 46% and the cultural theme contributes toa lower percentage of around 5% while the economic and social themes impact considerably 30% and 19%respectively. Furthermore, the developed framework is tested in a case study by comparing an emerging walling material, Cement Stabilized Earth Blocks with conventional materials such as Burnt Clay Bricks and Cement Sand Blocks. Technique for Order Preference by Similarities to Ideal Solution was carried out to compare and rank the respective walling materials under different scenarios. Accordingly, Cement Stabilized Earth Blocks is concluded to be the best alternative when analyzed in the eco-design concept. The proposed framework could be highly beneficial for industry practitioners in tropical underdeveloped countries and indigenous communities in choosing community-preferred, affordable, and environmentally friendly construction materials
... Benchmarking is extensively used in the literature to measure the existing performance and offer a continuous improvement pathway (He et al. 2021;Amer and Attia 2019;Lin et al. 2011). In building sector, most benchmark studies either focus on energy performance (Fumo et al. 2010;Torcelini et al. 2008;Lee and Burnett 2008) or green building rating systems (Ferreira et al. 2023). ...

Modular construction has become exceedingly relevant against the current scenario of increasing housing demand and can respond to this need in Canada due to its advantages of rapid construction. However, a holistic environmental sustainability framework for this construction method is still lacking. This paper proposes a hierarchical-based framework to benchmark the environmental performance of modular buildings versus conventional buildings. The framework identifies criteria and indicators affecting environmental sustainability, makes composite indicators, and establishes performance benchmarks. Based on expert survey, six criteria (construction waste management, energy performance and efficiency strategies, site disruption and appropriate strategies, renewable and environmentally preferable products, regional materials, and renewable energy use) are first identified. The related indicators and sub-indicators are combined to develop indices using Technique for Order of Preference by Similarity to Ideal Solution. Robust benchmark scales were established through application of Monte Carlo analysis on data collected through experts. Finally, the developed indices were compared against the benchmark scales at different assessment levels. The proposed framework was examined for two single-family modular buildings in British Columbia, Canada. The overall environmental performance benchmarking informs the policy makers on the usefulness of modular buildings, while the criteria-level indices direct the construction industry practitioners to improve the low performing indicators. The proposed framework will enhance the sustainability of modular and offsite construction in Canada. Graphical abstract
... Researchers are increasingly applying a range of methods to study the potential for urban densification from a city or neighbourhood scale (e.g., Amer et al., 2017 andBroitman and Koomen, 2015;Vuckovic et al. (2017) to a national scale (Bibby et al. 2020;Wang et al., 2019). Amer et al. (2017Amer et al. ( , 2019 developed a method to assess density potentials through roof-stacking at the building level for Brussel. Bolton (2021) developed a new tool, the Space Ratio, defined as the ratio of the existing density to the permissible density (the developable density according to a specified policy or scenario), for measuring and mapping density potentials in London. ...

Regional-scale urban residential densification provides an opportunity to tackle multiple challenges of sustainability in cities. But framework for detailed large-scale analysis of densification potentials and their integration with natural capital to assess the housing capacity is lacking. Using a combination of Machine Learning Random Forests algorithm and exploratory data analysis (EDA), we propose density scenarios and housing-capacity estimates for the potential residential lands in the Oxford-Cambridge Arc region (whose current population of 3.7 million is expected to increase up to 4.7 million in 2035) in the UK. A detailed analysis was done for Oxfordshire, assuming different densities in urban and rural areas and protecting lands with high-value natural capital from development. For a 30,000 dwellings-per-year scenario, the land allocated in Local Plans could cover housing growth in the four districts but not in Oxford City itself (which accounts for 48% of the demand); only 19% of the need would be covered in low but 59% in high housing density scenarios. Our study suggests a decision-support method for quantifying how the impact of housing growth on natural capital can be significantly reduced using more compact development patterns, protection of land with high-value natural capital, and use of low-biodiversity brownfield sites where available.
... In addition to wood creating beneficial opportunities when constructing new dwellings, wood-based materials and building technologies are also applicable when renovating old residential multistory buildings (e.g., Höfler et al., 2015). They may be used in façades (i.e., energy renovations) (Sandberg et al., 2016;Pan et al., 2020;Urbikain, 2020) and as rooftop extensions (i.e., additional floors added to existing buildings to increase urban density) (Amer and Attia, 2019;Wijnants et al., 2019;Karjalainen et al., 2021;) (herewith referred to as wooden retrofits). Likewise to new residential WMC, wooden retrofits are driven by expected sustainability benefits (e.g., energy efficiency and carbon dioxide emission decreases) (Pihelo et al., 2020). ...

This paper introduces and further applies an approach to support the decision makers in construction projects differentiating among a variety of deep excavation supporting systems (DESSs). These kinds of problems include dealing with uncertainty in data, multi-criteria affecting the decision, and multi-alternatives to select one from them. The proposed approach combines the analytic hierarchy process (AHP) with the fuzzy technique for order of preference by similarity to ideal solution (fuzzy TOPSIS) in a multicriteria decision-making (MCDM) model. The MCDM model emphasize the ability to combine expert knowledge, cost calculations, and laboratory test results for soil properties to achieve the scope. The model proved it had a superior ability to deal with the complexity and vague data that are related to construction projects. Furthermore, it was applied to a real case study for a governmental housing project in Egypt. Secant pile walls, sheet pile walls, and soldier piles and lagging are selected and studied as being the most common DESSs and as they satisfy the project requirements. The model utilized four criteria and fourteen comparing factors, including site characteristics, safety, cost, and environmental impacts. Based on the results of the model application on the investigated case study, a decision was reached that using secant piles as a supporting system in this project is mostly preferred. Furthermore, sheet pile wall, and soldier piles and lagging, come next in the ranking order. A sensitivity analysis is carried out to investigate how sensitive the results are to the criteria weights. In addition, the paper discusses in detail the reasons and factors which affect and control the decision-making process.

A significant research gap exists concerning the thermal properties of lightweight roofs, as extensive investigations have predominantly focused on their mechanical characteristics. However, there is a notable dearth of studies addressing the thermal behavior of lightweight roof systems. The comprehension of thermal properties in lightweight roofs is of paramount importance, as it enables the promotion of energy-efficient design practices. The absence of comprehensive research in this domain constrains the optimization of thermal insulation mechanisms within lightweight roof constructions. Consequently, this hinders developments aimed at reducing energy consumption in buildings. To bridge this research gap, this study investigates the thermal performance of two lightweight roofs called waffle slab and bubble deck in three different climates, and compare them with conventional cement block roofs. Results revealed that Valencia had the lowest heating load due to its moderate climate, while Denver showed the minimum cooling load due to colder temperatures. The bubble deck roof outperformed other roofs in terms of heat loss reduction, achieving an average of 76% in winter and 41% in summer. Additionally, the bubble deck roof demonstrated the best overall efficiency (72% on average) and improved thermal comfort during summer, with lower energy consumption. Exergy analysis showed that the bubble deck roof significantly reduced input and output exergy, indicating its superior energy conservation capabilities compared to waffle slab and cement block roofs. These findings emphasize the potential benefits of lightweight roofs, particularly the bubble deck, in enhancing energy efficiency and occupant comfort.

The criteria for selecting insulating materials in the energy retrofitting of industrial buildings can often be conflicting, leading to a multicriteria decision-making problem. This is the first study to take an indirect elicitation approach to solving this selection problem, which is particularly applicable in the preliminary phases of negotiation with all of the decision-makers involved. We introduce a nonlinear indirect elicitation approach for PROMETHEE II that uses Bézier curves as nonlinear preference curves to fit the decision-maker's preferences, i.e., indifference and/or strict preferences for insulating materials that are taken as references. In our approach, no parameters need to be initially set, and thus, it has the advantage of setting both the preference curves on the criteria and the criteria weights when the decision-maker is not confident. The set of Bézier curves and criteria weights that best fits the preferences given by the decision-maker may thus be achieved and visualized, which provides managerial insights as it makes explicit the preference structure of the decision-maker. We use a case study to validate our proposal in a real setting and confirm that linear preference curves would have achieved less clear relations between the insulating materials used as references respect to Bèzier curves.

Sustainable built environment has been of interest to many stakeholders in the recent years. However, life cycle economic performance as one of the key dimensions of sustainability has not been sufficiently investigated for buildings constructed using off-site construction methods such as modular construction. This research has proposed a framework to benchmark the life cycle economic sustainability of single-family modular homes. First, suitable economic performance criteria were selected and suitable measurable economic performance indicators were developed under each criterion. A performance level function was established for each indicator by which all indicators can be calculated and presented by a normalized performance level that enables combining quantitative and qualitative indicators. Subsequently, a multi-criteria decision analysis-based methodology was employed to develop a set of economic sustainability indices at criteria level and also at the overall economic sustainability performance level. To compare and contrast the developed indices of a given modular building with the performance of similar conventional buildings, suitable performance benchmarks scales were established using the data of the historical economic performance of conventional homes. To examine the application of the proposed framework, two case study modular homes in British Columbia, Canada were analyzed. The results showed that both benchmarking homes performed ‘Excellent’ with respect to the overall economic sustainability. However, improvement is required to enhance the economic performance with respect to a number of criteria. The proposed framework can assist the construction decision makers, developers, and contractors with making informed decisions on the selection of the construction method. Furthermore, it can be used to address the underperforming areas over the life cycle of a modular building, even if the decision on the construction method has already been made.

Nowadays, major European cities witness one of their greatest challenges in history. Increasing migration from the rural areas, not to mention the massive migrations from the east, contributes in aggravating the challenge. As a response, United Nations urban agendas promote for developing urban spatial frameworks based on appropriate compactness, polycentrism and mixed use, preventing urban sprawl and marginalization. In this research, a methodology is presented that aids the decision making on roof stacking as a sustainable approach towards urban densification. Brussels Capital Region in Belgium is chosen as a case study to represent the outcomes of a methodology that has been developed to identify urban densification potential through roof stacking. Further applications to generalize the approach to fit other cities in Europe would help create additional opportunities to develop an automated tool for estimating such potentials on a wider scope.

This paper describes the development of a prototype systematic web-based decision aid for selecting low-carbon refurbishment solutions for multi-story residential buildings in high-density subtropical cities, with special reference to Hong Kong. 88 potential general sustainable refurbishment approaches are identified from a comprehensive literature review, later narrowed down to 39 considered to be relevant to Hong Kong's climatic condition and building characteristics, and then to 17 solutions for common areas and 14 for privately-occupied areas after interviewing industry experts and verification by questionnaire survey of the occupants. A set of methods is then established through literature review and energy simulation based on a case study, to calculate the CO2 emission reductions achievable. The system is then described, which includes a set of criteria for identifying individual applicable refurbishment solutions, methods of calculating CO2 emission reductions, parameter input/output and user interface design for a particular building. Finally, a validation process involving industry experts is followed to ascertain the system's practical usefulness and possible refinements for implementation.

Low-density urban models, widely diffused in Spain until 2008, have been strongly criticized because they produce a great strain on the land, high infrastructure costs, increasing maintenance expenses, energy waste and pollution from excessive transport, time wasted commuting and more bedroom communities. To counterbalance this effect, opponents are claiming for a review of the capacity that the conventional city, with its higher population density and mixed uses, may still possess. One possibility that has been explored is the vertical extension of buildings, which capitalizes on the remaining buildable space characteristic of many older buildings, and at the same time, refurbishes the housing block and improves standards of energy efficiency, safety and accessibility. The challenge is not only technical - it is clear what needs to be done and how to do it - but it is also social and fiscal; in other words, how do we get organized and how do we finance such a project? The preferred construction system for vertical extensions is industrialized and uses two main materials: steel and wood. The system involves the use of two-dimensional panels and 3D pods that, once completed in the factory, are transported to the worksite, lifted by a crane and installed on the roof of the building. From refurbishing the existing building to adding the new vertical extension, the entire operation takes four months. The experience of this vision and its application in the area of the Example in Barcelona, coming soon to other central neighborhoods in Spanish cities, allows us to present our first results: the detection of over 2,000 buildings with remaining buildable space, the need to vertically extend 50 buildings and our completed projects, in some cases already inhabited, of which half a dozen are currently undergoing environmental evaluation using our own tool.

Trees, and their derivative products, have been used by societies around the world for thousands of years. Contemporary construction of tall buildings from timber, in whole or in part, suggests a growing interest in the potential for building with wood at a scale not previously attainable. As wood is the only significant building material that is grown, we have a natural inclination that building in wood is good for the environment. But under what conditions is this really the case? The environmental benefits of using timber are not straightforward; although it is a natural product, a large amount of energy is used to dry and process it. Much of this can come from the biomass of the tree itself, but that requires investment in plant, which is not always possible in an industry that is widely distributed among many small producers. And what should we build with wood? Are skyscrapers in timber a good use of this natural resource, or are there other aspects of civil and structural engineering, or large-scale infrastructure, that would be a better use of wood? Here, we consider a holistic picture ranging in scale from the science of the cell wall to the engineering and global policies that could maximise forestry and timber construction as a boon to both people and the planet.

Many design systems are developed in the context of non-prefabricated buildings, and cannot be well suitable for prefabricated buildings which are being popular at present. In order to solve the problem, this paper introduces Design for Manufacture and Assembly (DFMA) into prefabricated building design, and combines it with parametric design of Building Information Modeling (BIM) to develop the concept and process of DFMA-oriented parametric design. For making DFMA-oriented parametric design implemented better, DFMA-oriented architectural design team, precast component creation process based on family template and DFMA, DFMA-oriented BIM re-development process, and optimization process of DFMA-oriented prefabricated building information model are also explored and developed. In the end, some principles of DFMA-oriented parametric design are partially reflected by several examples, and DFMA-oriented parametric design needs to be constantly improved according to its subsequent actual use.

Modular construction gained considerable momentum over the last decade due to its positive impact on project cost, schedule, quality, and safety. Current literature in this field focused on cranes selection and scheduling methods, without due consideration for optimum module configuration. This paper introduces a novel modular suitability indicator which utilizes five indices; 1) connections index (CI) to evaluate module connections using the matrix clustering technique, 2) transportation dimensions index (TDI) to evaluate module dimensions' effects on transportation, 3) transportation shipping distance index (TSDI) to evaluate the distance between manufacturing facility and the construction site, 4) crane cost penalty index (CCPI) to evaluate the crane cost relevant to the module placing rate, and 5) concrete volume index (CVI) to evaluate the project's foundation concrete quantities. Calculating the modular suitability index (MSI) provides a unified indicator to accomplish a near optimum selection of module configuration for efficient delivery in residential construction.

Sustainable residential buildings and a sustainable housing development (‘sustainable housing’) are key factors in the sustainability strategy of the German government. Certification systems have been developed to assess sustainable housing and to better inform stakeholders and hence improve sustainability in the housing sector. Currently, however, a variety of different certification systems exists to assess sustainable housing using different sets of indicators. The supply of different certification systems to measure the same (‘sustainability’) raises questions of validity of the assessment instruments. Also, different stakeholders hold different interests with regard to sustainability certification systems, which leads to investigate the legitimacy of certification systems. In this study, we applied the theory of social institutions to investigate legitimacy of sustainability certification in the housing sector. To find out about the validity of sustainability measurement, this article presents a survey where real estate stakeholders were asked to evaluate indicators applied by different sustainability certification systems. Results showed high heterogeneity of tastes towards indicators of sustainable housing. Results also identified potential ‘areas of conflicts’ where stakeholders differed most widely in the evaluation of indicators.

Modular construction has been recognized as one of the primary methods for sustainable off-site construction in the recent past. However, in a given building project, the process of selecting a suitable construction method among different options is still made based on anecdotal evidence. Thus, it is imperative to evaluate the life cycle sustainability of different construction methods. The sustainability evaluation criteria (SEC) comprise the triple bottom line (TBL) sustainability categories, i.e., environmental, economic, and social, in which each category includes numerous sustainability performance indicators (SPI) associated with different life cycle phases of a building. The most significant step for comparative assessment of the life cycle sustainability of buildings is to develop suitable SPIs. In this paper, a methodology is used to identify and select the appropriate SPIs for life cycle sustainability evaluation of modular and conventional construction. Through a comprehensive literature review, 33 TBL SPIs were identified to address the life cycle sustainability performance of buildings. In order to investigate the applicability (importance) of the identified sustainability indicators when comparing the sustainability of modular and conventional buildings, a survey was designed and conducted. Subsequently, the construction professionals' perceptions about the applicability of these sustainability indicators were captured on a 5-point Likert scale. The reliability of questionnaire was analyzed using Cronbach's alpha measure. Then, all the SPIs were ranked based on their severity index (SI) values ranging between 0 and 100% correspond to a severity scale from “very low” to “extremely high” importance levels. All the SPIs were ranked under the overall TBL SPIs as well as within their associated sustainability categories. The analyses showed that 33% of the environmental SPIs, 67% of the economic SPIs, and 42% of the social SPIs were rated equal to or greater than “high” on severity scale (i.e., Severity Index ≥75%). The economic dimension of sustainability is still the governing concern of the construction industry practitioners. Moreover, the results revealed that attention to the social dimension of sustainability is increasing compared to the environmental dimension. This paper contributes to the current body of knowledge by highlighting the most applicable indicators for comparing and contrasting the sustainability of modular and conventional construction.
