Sustainable urban planning is essential in mediating the natural and built environments globally, yet, there is little progress as regards its attainment in developing countries. Rapid and unplanned urbanization continue to threaten the sustainability of many cities in Africa. By selecting Morogoro Municipal Council (MMC) in Tanzania as an example, this study applied well-known remote sensing techniques to understand the dynamics of urban growth and the implications for sustainable urban planning. The study analyzes spatio-temporal characteristics for eighteen years (2000–2018) based on urban land density using gradient and grid-based analysis to further examine land use and urban land density nexus. The results indicate declining urban land densities with distance to the city center, indicating a less compact and fragmented development at the urban fringes; and northward development with limited development to the south of MCC. The knowledge and understanding of the patterns of spatio-temporal conditions, land use planning, and management interventions in MMC are necessary for addressing the inadequacies associated with rapid urbanization within the study area. On this basis, we propose a shift from the modernist to the communicative planning strategy that strongly integrates the urban social, economic, and environmental imperatives, while being adaptable to evolving realities. This plan should also aim to curtail urban sprawl and create a viable city system and economically prosperous city structure for MMC.

In Egypt's case, the CDW problem has become a significant challenge, and the need to find sustainable solutions is overwhelming. Based on recent investigations in the literature, it was found that six main factors are affecting CDW reduction (CDWR) as follows: (1) waste-efficient materials procurement measures; (2) waste-efficient materials procurement models; (3) green materials procurement approach; (4) legislation; (5) culture & behaviour; and (6) awareness. In this study, a representative sample of Egyptian construction firms was screened to (1) investigate the applicability and effectiveness of CDWR factors in the Egyptian construction sector; and (2) examine the relationship between these factors and CDWR. The results revealed that (1) among different factors, “correct materials purchase” is the most applied item while “reducing overall material use by using prefabricated elements and highly durable materials” is the most effective item; and (2) there are statistically significant positive relationships between CDWR and different factors except “legislation”. The results demonstrate the necessity of developing a conceptual framework, as a next research initiative, consisting of these different factors for CDWR in Egypt.

The construction industry is a vital part of every nation’s economy. Construction activities influence the social, environmental, and economic aspects of sustainability. There are so many barriers to sustainable construction and demolition waste management (C&DWM). This study aims to identify barriers for effective sustainable C&DWM in developed and developing countries. To achieve the objective, 11 barriers have been selected and identified based on an excessive and comprehensive literature review, and then reviewed by experts. These reviewed barriers were further examined by various experts within different organizations using a questionnaire survey. Ranking of the barriers was carried out using the Relative Importance Index (RI), and the results were statistically analyzed using Statistical Package for Social Sciences (SPSS). Practical solutions were proposed to overcome the identified barriers. The overall ranking of barriers by RI indicates that insufficient attention paid to C&DWM, lack of law enforcement, lack of regulation, and financial constraints represent the four major barriers to sustainable C&DWM in these countries. The findings of this study and the proposed solutions are enablers for decision-makers to develop effective strategies to tackle construction and demolition wastes in sustainable manners.

En el caso particular de los residuos de materiales, la industria de la construcción en todo el mundo representa aproximadamente el 50% del SW generado anualmente a nivel mundial. Además, los materiales de construcción pueden aportar hasta el 50% del coste total del proyecto. En consecuencia, las implicaciones negativas de la industria de la construcción han obligado a muchas naciones a desarrollar sistemas de calificación de edificios ecológicos para preservar el medio ambiente, promover la eficiencia económica del uso de los recursos y mejorar la calidad de vida de los ciudadanos, que son aspectos necesarios para lograr el triple resultado final (TBL) de la sostenibilidad. Recientemente, Egipto desarrolló el Sistema de Clasificación de la Pirámide Verde (GPRS) en su primera versión en 2011. A través de la investigación del GPRS y especialmente de su categoría de Materiales y Recursos (M&R), se identificaron algunas deficiencias. Para mejorar el GPRS, este documento tiene como objetivo investigar el GPRS y compararlo con sus pares BREEAM y LEED con un enfoque especial en la categoría de M&R. Los resultados de la investigación y la comparación ayudaron a proponer sugerencias que pueden mejorar el GPRS en el nivel categórico y el nivel de criterios de la categoría de M&R. Además, la importancia de la categoría M&R se demuestra mediante un estudio de caso mediante el uso de hojas de palma como material verde para el refuerzo de hormigón para demostrar el impacto positivo de esta categoría en el TBL de la sostenibilidad. Malgré les contributions tangibles de l'industrie de la construction au développement social et à la croissance économique, elle est connue pour sa surconsommation de ressources naturelles et sa production de déchets solides (SW), qui ont tous deux des impacts négatifs majeurs sur l'environnement naturel. Dans le cas particulier des déchets de matériaux, l'industrie de la construction dans le monde représente environ 50 % des SW générés annuellement dans le monde. En outre, les matériaux de construction peuvent contribuer jusqu'à 50 % du coût total du projet. En conséquence, les implications négatives de l'industrie de la construction ont contraint de nombreux pays à développer des systèmes d'évaluation des bâtiments écologiques afin de préserver l'environnement, de promouvoir l'efficacité économique de l'utilisation des ressources et d'améliorer la qualité de vie des citoyens, qui sont des aspects nécessaires pour atteindre le triple résultat (TBL) de la durabilité. Récemment, l'Égypte a développé le système d'évaluation de la pyramide verte (GPRS) dans sa première version en 2011. En enquêtant sur le GPRS et en particulier sur sa catégorie Matériaux et Ressources (M&R), certaines lacunes ont été identifiées. Pour améliorer le GPRS, cet article vise à étudier le GPRS et à le comparer avec ses pairs BREEAM et LEED, en mettant l'accent sur la catégorie M&R. Les résultats de l'enquête et de la comparaison ont permis de proposer des suggestions susceptibles d'améliorer le GPRS au niveau catégorique et au niveau des critères de la catégorie M&R. De plus, l'importance de la catégorie M&R est démontrée par une étude de cas en utilisant des frondes de palmier comme matériau vert pour le renforcement du béton afin de prouver l'impact positif de cette catégorie sur le TBL de la durabilité. Despite the tangible contributions of the construction industry to social development and economic growth, it is known for its natural resources overconsumption and solid waste (SW) generation both of which have major negative impacts on the natural environment. In the particular case of materials waste, the construction industry worldwide accounts for about 50% of global annual generated SW. In addition, construction materials may contribute up to 50% of the total project cost. Accordingly, the negative implications of the construction industry have compelled many nations to develop green building rating systems in order to preserve the environment, promote the economic efficiency of using resources, and enhance the quality of citizens' lives which are necessary aspects for achieving the triple bottom line (TBL) of sustainability. Recently, Egypt developed the Green Pyramid Rating System (GPRS) in its first version in 2011. Through investigating the GPRS and especially its Materials and Resources (M&R) category, some shortcomings were identified. Towards improving the GPRS, this paper aims to investigate the GPRS and compare it with its peers BREEAM and LEED with a special focus on M&R category. The investigation and comparison results helped proposing suggestions which may improve the GPRS on the categorical level and the criteria level of M&R category. Moreover, the importance of M&R category is demonstrated by a case study through using palm fronds as a green material for concrete reinforcement to prove the positive impact of this category on the TBL of sustainability. على الرغم من المساهمات الملموسة لصناعة البناء والتشييد في التنمية الاجتماعية والنمو الاقتصادي، إلا أنها معروفة باستهلاكها المفرط للموارد الطبيعية وتوليد النفايات الصلبة (SW) وكلاهما له آثار سلبية كبيرة على البيئة الطبيعية. في حالة نفايات المواد على وجه الخصوص، تمثل صناعة البناء والتشييد في جميع أنحاء العالم حوالي 50 ٪ من النفايات الصلبة المولدة سنويًا على مستوى العالم. بالإضافة إلى ذلك، قد تساهم مواد البناء بما يصل إلى 50 ٪ من إجمالي تكلفة المشروع. وبناءً على ذلك، أجبرت الآثار السلبية لصناعة البناء والتشييد العديد من الدول على تطوير أنظمة تصنيف المباني الخضراء من أجل الحفاظ على البيئة، وتعزيز الكفاءة الاقتصادية لاستخدام الموارد، وتعزيز جودة حياة المواطنين وهي جوانب ضرورية لتحقيق خط الأساس الثلاثي (TBL) للاستدامة. في الآونة الأخيرة، طورت مصر نظام تصنيف الهرم الأخضر (GPRS) في نسخته الأولى في عام 2011. من خلال التحقيق في GPRS وخاصة فئة المواد والموارد (M&R)، تم تحديد بعض أوجه القصور. نحو تحسين GPRS، تهدف هذه الورقة إلى التحقيق في GPRS ومقارنتها مع نظرائها BREEAM و LEED مع التركيز بشكل خاص على فئة M&R. ساعدت نتائج التحقيق والمقارنة في اقتراح الاقتراحات التي قد تحسن GPRS على المستوى الفئوي ومستوى معايير فئة الرصد والإبلاغ. علاوة على ذلك، تتجلى أهمية فئة M&R من خلال دراسة حالة من خلال استخدام سعف النخيل كمادة خضراء لتعزيز الخرسانة لإثبات التأثير الإيجابي لهذه الفئة على TBL للاستدامة.

Purpose The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate. Design/methodology/approach This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis. Findings This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings. Originality/value This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.

Hence, adopting green building (GRB) practices can be helpful in achieving sustainable development goals. Therefore, this study aims to identify the factors affecting the intention to adopt GRB practices by extending theory of planned behavior (TPB). Design/methodology/approach Using non-probability purposive sampling technique, data was gathered from consultant and contractor engineers in the construction industry through a questionnaire. The analysis was done using partial least square-structural equation modeling technique on a useful sample of 290. Findings Findings revealed that the core constructs of TPB [i.e. attitude (AT), subjective norms (SUBN) and perceived behavioral control (PBC)] significantly affect the intention to adopt GRB practices. Moreover, government support and knowledge of green practices (KNGP) were found to be critical influencing factors on AT, SUBNs and PBC. Lastly, the findings confirmed that environmental concerns (ENC) play as a moderating between SUBN and intention to adopt GRB practices, as well as AT and intention to adopt GRB practices. Practical implications This study contributes to existing knowledge on GRB, offering evidence base for policy choices regarding climate change adaptation and mitigation in the construction industry. Originality/value This study provides insights from the perspective of a developing economy and confirms the applicability of TPB in the adoption of GRB practices. Moreover, this study confirms the moderation role of ENC in between TPB constructs and intention to GRB that is not tested earlier in the context of GRB. This study also confirms that government sustainable support positively affects PBC, and KNGP significantly affects SUBNs.

This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.Design/methodology/approachThe paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.FindingsThe main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.Originality/valueBy reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.

Omar; Ayman Ahmed Ezzat Othman; Obas John Ebohon;AbstractThe construction industry is plagued with significant construction and demolition waste (C&DW) generated during various phases of construction projects. This waste has created a universal, pervasive, and enduring problem globally. To propose practical solutions to resolve this consequential issue, this research adopted a quantitative approach in two stages. The first stage involved an online survey, administrated to 360 methodically selected construction organisations working in Egypt, to evaluate the impact of six main factors on C&DW reduction (C&DWR). The six main factors are as follows: (1) materials procurement measures (MPMR); (2) materials procurement models (MPMO); (3) green building practices (GBPR); (4) legislation (LG); (5) culture and behaviour (CB); and (6) awareness (AW). The second stage comprised multivariate statistical analysis via the structural equation modelling (SEM) approach to develop an integrated framework for C&DWR, to support Egypt’s vision 2030. The results revealed that these six factors positively affect C&DWR in Egypt. Additionally, the study found that GBPR has the highest importance value of 0.293 and the highest performance rate of 92.169. However, CB has the second highest importance value of 0.238 whilst it has the lowest performance of 72.08 among the six factors. This paper proposes practical recommendations for the government and the construction sector to reduce the C&DW in support of Egypt's Vision 2030.

It leads to deterioration of the triple bottom line of sustainability. Unfortunately, the CDW management research in Egypt lacks studies investigating (1) the variations in CDW generation (CDWG) among different types of construction projects, and (2) the factors affecting CDW reduction (CDWR). Based on a benchmarking approach, this research (1) quantifies CDW in terms of generation rates and costs among different construction project types in Egypt, and (2) investigates the relationship between CDWG and different adopted CDWR factors. Using structured interviews, a comparative case study was conducted to investigate industrial, residential, commercial, and infrastructure projects. Analysis of results demonstrated that CDWG rates and costs differ from one project type to another due to the project's nature, size, and complexity on the one hand, and the applied CDWR factors such as waste-efficient practices, awareness, culture & behaviour, and legislation on the other hand. On average among the four project types, it was found that “timber”, “sand”, and “bricks/blocks” are the most wasteful materials. It was also found that “practices” and “legislation” are the least applied CDWR factors on average among the four project types, which need to be better applied for better CDWR results.

Sustainable urban planning is essential in mediating the natural and built environments globally, yet, there is little progress as regards its attainment in developing countries. Rapid and unplanned urbanization continue to threaten the sustainability of many cities in Africa. By selecting Morogoro Municipal Council (MMC) in Tanzania as an example, this study applied well-known remote sensing techniques to understand the dynamics of urban growth and the implications for sustainable urban planning. The study analyzes spatio-temporal characteristics for eighteen years (2000–2018) based on urban land density using gradient and grid-based analysis to further examine land use and urban land density nexus. The results indicate declining urban land densities with distance to the city center, indicating a less compact and fragmented development at the urban fringes; and northward development with limited development to the south of MCC. The knowledge and understanding of the patterns of spatio-temporal conditions, land use planning, and management interventions in MMC are necessary for addressing the inadequacies associated with rapid urbanization within the study area. On this basis, we propose a shift from the modernist to the communicative planning strategy that strongly integrates the urban social, economic, and environmental imperatives, while being adaptable to evolving realities. This plan should also aim to curtail urban sprawl and create a viable city system and economically prosperous city structure for MMC.

In Egypt's case, the CDW problem has become a significant challenge, and the need to find sustainable solutions is overwhelming. Based on recent investigations in the literature, it was found that six main factors are affecting CDW reduction (CDWR) as follows: (1) waste-efficient materials procurement measures; (2) waste-efficient materials procurement models; (3) green materials procurement approach; (4) legislation; (5) culture & behaviour; and (6) awareness. In this study, a representative sample of Egyptian construction firms was screened to (1) investigate the applicability and effectiveness of CDWR factors in the Egyptian construction sector; and (2) examine the relationship between these factors and CDWR. The results revealed that (1) among different factors, “correct materials purchase” is the most applied item while “reducing overall material use by using prefabricated elements and highly durable materials” is the most effective item; and (2) there are statistically significant positive relationships between CDWR and different factors except “legislation”. The results demonstrate the necessity of developing a conceptual framework, as a next research initiative, consisting of these different factors for CDWR in Egypt.

The construction industry is a vital part of every nation’s economy. Construction activities influence the social, environmental, and economic aspects of sustainability. There are so many barriers to sustainable construction and demolition waste management (C&DWM). This study aims to identify barriers for effective sustainable C&DWM in developed and developing countries. To achieve the objective, 11 barriers have been selected and identified based on an excessive and comprehensive literature review, and then reviewed by experts. These reviewed barriers were further examined by various experts within different organizations using a questionnaire survey. Ranking of the barriers was carried out using the Relative Importance Index (RI), and the results were statistically analyzed using Statistical Package for Social Sciences (SPSS). Practical solutions were proposed to overcome the identified barriers. The overall ranking of barriers by RI indicates that insufficient attention paid to C&DWM, lack of law enforcement, lack of regulation, and financial constraints represent the four major barriers to sustainable C&DWM in these countries. The findings of this study and the proposed solutions are enablers for decision-makers to develop effective strategies to tackle construction and demolition wastes in sustainable manners.

En el caso particular de los residuos de materiales, la industria de la construcción en todo el mundo representa aproximadamente el 50% del SW generado anualmente a nivel mundial. Además, los materiales de construcción pueden aportar hasta el 50% del coste total del proyecto. En consecuencia, las implicaciones negativas de la industria de la construcción han obligado a muchas naciones a desarrollar sistemas de calificación de edificios ecológicos para preservar el medio ambiente, promover la eficiencia económica del uso de los recursos y mejorar la calidad de vida de los ciudadanos, que son aspectos necesarios para lograr el triple resultado final (TBL) de la sostenibilidad. Recientemente, Egipto desarrolló el Sistema de Clasificación de la Pirámide Verde (GPRS) en su primera versión en 2011. A través de la investigación del GPRS y especialmente de su categoría de Materiales y Recursos (M&R), se identificaron algunas deficiencias. Para mejorar el GPRS, este documento tiene como objetivo investigar el GPRS y compararlo con sus pares BREEAM y LEED con un enfoque especial en la categoría de M&R. Los resultados de la investigación y la comparación ayudaron a proponer sugerencias que pueden mejorar el GPRS en el nivel categórico y el nivel de criterios de la categoría de M&R. Además, la importancia de la categoría M&R se demuestra mediante un estudio de caso mediante el uso de hojas de palma como material verde para el refuerzo de hormigón para demostrar el impacto positivo de esta categoría en el TBL de la sostenibilidad. Malgré les contributions tangibles de l'industrie de la construction au développement social et à la croissance économique, elle est connue pour sa surconsommation de ressources naturelles et sa production de déchets solides (SW), qui ont tous deux des impacts négatifs majeurs sur l'environnement naturel. Dans le cas particulier des déchets de matériaux, l'industrie de la construction dans le monde représente environ 50 % des SW générés annuellement dans le monde. En outre, les matériaux de construction peuvent contribuer jusqu'à 50 % du coût total du projet. En conséquence, les implications négatives de l'industrie de la construction ont contraint de nombreux pays à développer des systèmes d'évaluation des bâtiments écologiques afin de préserver l'environnement, de promouvoir l'efficacité économique de l'utilisation des ressources et d'améliorer la qualité de vie des citoyens, qui sont des aspects nécessaires pour atteindre le triple résultat (TBL) de la durabilité. Récemment, l'Égypte a développé le système d'évaluation de la pyramide verte (GPRS) dans sa première version en 2011. En enquêtant sur le GPRS et en particulier sur sa catégorie Matériaux et Ressources (M&R), certaines lacunes ont été identifiées. Pour améliorer le GPRS, cet article vise à étudier le GPRS et à le comparer avec ses pairs BREEAM et LEED, en mettant l'accent sur la catégorie M&R. Les résultats de l'enquête et de la comparaison ont permis de proposer des suggestions susceptibles d'améliorer le GPRS au niveau catégorique et au niveau des critères de la catégorie M&R. De plus, l'importance de la catégorie M&R est démontrée par une étude de cas en utilisant des frondes de palmier comme matériau vert pour le renforcement du béton afin de prouver l'impact positif de cette catégorie sur le TBL de la durabilité. Despite the tangible contributions of the construction industry to social development and economic growth, it is known for its natural resources overconsumption and solid waste (SW) generation both of which have major negative impacts on the natural environment. In the particular case of materials waste, the construction industry worldwide accounts for about 50% of global annual generated SW. In addition, construction materials may contribute up to 50% of the total project cost. Accordingly, the negative implications of the construction industry have compelled many nations to develop green building rating systems in order to preserve the environment, promote the economic efficiency of using resources, and enhance the quality of citizens' lives which are necessary aspects for achieving the triple bottom line (TBL) of sustainability. Recently, Egypt developed the Green Pyramid Rating System (GPRS) in its first version in 2011. Through investigating the GPRS and especially its Materials and Resources (M&R) category, some shortcomings were identified. Towards improving the GPRS, this paper aims to investigate the GPRS and compare it with its peers BREEAM and LEED with a special focus on M&R category. The investigation and comparison results helped proposing suggestions which may improve the GPRS on the categorical level and the criteria level of M&R category. Moreover, the importance of M&R category is demonstrated by a case study through using palm fronds as a green material for concrete reinforcement to prove the positive impact of this category on the TBL of sustainability. على الرغم من المساهمات الملموسة لصناعة البناء والتشييد في التنمية الاجتماعية والنمو الاقتصادي، إلا أنها معروفة باستهلاكها المفرط للموارد الطبيعية وتوليد النفايات الصلبة (SW) وكلاهما له آثار سلبية كبيرة على البيئة الطبيعية. في حالة نفايات المواد على وجه الخصوص، تمثل صناعة البناء والتشييد في جميع أنحاء العالم حوالي 50 ٪ من النفايات الصلبة المولدة سنويًا على مستوى العالم. بالإضافة إلى ذلك، قد تساهم مواد البناء بما يصل إلى 50 ٪ من إجمالي تكلفة المشروع. وبناءً على ذلك، أجبرت الآثار السلبية لصناعة البناء والتشييد العديد من الدول على تطوير أنظمة تصنيف المباني الخضراء من أجل الحفاظ على البيئة، وتعزيز الكفاءة الاقتصادية لاستخدام الموارد، وتعزيز جودة حياة المواطنين وهي جوانب ضرورية لتحقيق خط الأساس الثلاثي (TBL) للاستدامة. في الآونة الأخيرة، طورت مصر نظام تصنيف الهرم الأخضر (GPRS) في نسخته الأولى في عام 2011. من خلال التحقيق في GPRS وخاصة فئة المواد والموارد (M&R)، تم تحديد بعض أوجه القصور. نحو تحسين GPRS، تهدف هذه الورقة إلى التحقيق في GPRS ومقارنتها مع نظرائها BREEAM و LEED مع التركيز بشكل خاص على فئة M&R. ساعدت نتائج التحقيق والمقارنة في اقتراح الاقتراحات التي قد تحسن GPRS على المستوى الفئوي ومستوى معايير فئة الرصد والإبلاغ. علاوة على ذلك، تتجلى أهمية فئة M&R من خلال دراسة حالة من خلال استخدام سعف النخيل كمادة خضراء لتعزيز الخرسانة لإثبات التأثير الإيجابي لهذه الفئة على TBL للاستدامة.

Purpose The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate. Design/methodology/approach This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis. Findings This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings. Originality/value This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.

Hence, adopting green building (GRB) practices can be helpful in achieving sustainable development goals. Therefore, this study aims to identify the factors affecting the intention to adopt GRB practices by extending theory of planned behavior (TPB). Design/methodology/approach Using non-probability purposive sampling technique, data was gathered from consultant and contractor engineers in the construction industry through a questionnaire. The analysis was done using partial least square-structural equation modeling technique on a useful sample of 290. Findings Findings revealed that the core constructs of TPB [i.e. attitude (AT), subjective norms (SUBN) and perceived behavioral control (PBC)] significantly affect the intention to adopt GRB practices. Moreover, government support and knowledge of green practices (KNGP) were found to be critical influencing factors on AT, SUBNs and PBC. Lastly, the findings confirmed that environmental concerns (ENC) play as a moderating between SUBN and intention to adopt GRB practices, as well as AT and intention to adopt GRB practices. Practical implications This study contributes to existing knowledge on GRB, offering evidence base for policy choices regarding climate change adaptation and mitigation in the construction industry. Originality/value This study provides insights from the perspective of a developing economy and confirms the applicability of TPB in the adoption of GRB practices. Moreover, this study confirms the moderation role of ENC in between TPB constructs and intention to GRB that is not tested earlier in the context of GRB. This study also confirms that government sustainable support positively affects PBC, and KNGP significantly affects SUBNs.

This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.Design/methodology/approachThe paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.FindingsThe main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.Originality/valueBy reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.

Omar; Ayman Ahmed Ezzat Othman; Obas John Ebohon;AbstractThe construction industry is plagued with significant construction and demolition waste (C&DW) generated during various phases of construction projects. This waste has created a universal, pervasive, and enduring problem globally. To propose practical solutions to resolve this consequential issue, this research adopted a quantitative approach in two stages. The first stage involved an online survey, administrated to 360 methodically selected construction organisations working in Egypt, to evaluate the impact of six main factors on C&DW reduction (C&DWR). The six main factors are as follows: (1) materials procurement measures (MPMR); (2) materials procurement models (MPMO); (3) green building practices (GBPR); (4) legislation (LG); (5) culture and behaviour (CB); and (6) awareness (AW). The second stage comprised multivariate statistical analysis via the structural equation modelling (SEM) approach to develop an integrated framework for C&DWR, to support Egypt’s vision 2030. The results revealed that these six factors positively affect C&DWR in Egypt. Additionally, the study found that GBPR has the highest importance value of 0.293 and the highest performance rate of 92.169. However, CB has the second highest importance value of 0.238 whilst it has the lowest performance of 72.08 among the six factors. This paper proposes practical recommendations for the government and the construction sector to reduce the C&DW in support of Egypt's Vision 2030.

It leads to deterioration of the triple bottom line of sustainability. Unfortunately, the CDW management research in Egypt lacks studies investigating (1) the variations in CDW generation (CDWG) among different types of construction projects, and (2) the factors affecting CDW reduction (CDWR). Based on a benchmarking approach, this research (1) quantifies CDW in terms of generation rates and costs among different construction project types in Egypt, and (2) investigates the relationship between CDWG and different adopted CDWR factors. Using structured interviews, a comparative case study was conducted to investigate industrial, residential, commercial, and infrastructure projects. Analysis of results demonstrated that CDWG rates and costs differ from one project type to another due to the project's nature, size, and complexity on the one hand, and the applied CDWR factors such as waste-efficient practices, awareness, culture & behaviour, and legislation on the other hand. On average among the four project types, it was found that “timber”, “sand”, and “bricks/blocks” are the most wasteful materials. It was also found that “practices” and “legislation” are the least applied CDWR factors on average among the four project types, which need to be better applied for better CDWR results.
