Item Awareness of Factors Contributing to Sustainable Construction in Nigeria(International Journal of Real Estate Studies, 2020-06) Amuda-yusuf, Ganiyu; Raheem, Wasiu Mayowa; Adebiyi, Ranti Taibat; Abdulraheem, Maimunat Orire; Idris, Soliu; Eluwa, Stephen EyinayaThe need to slow down climate change and global warming has made sustainable development major issue among policy makers and world leaders. Awareness on sustainability concept among industry practitioners is crucial in influencing design, materials selection and construction methods. The aim of this study is to examine the level of awareness on key sustainability concepts and factors that influence their adoption during construction by practitioners in Nigeria. Through an online survey, 120 copies of semi-structured questionnaire were administered on built environment practitioners such as architects, engineers, quantity surveyors, and builders working in client, contracting, consulting and academia with 77% response rate. Factorial two-way ANOVA was performed to examine if there are differences in the level of awareness of factors contributing to sustainable construction among the groupings. Also, binomial logit regression analysis was adopted in predicting the factors that significantly influence adoption of sustainability concept among practitioners in construction industry. The study revealed that professionals from client organization recorded highest (3.8) mean score in terms of awareness on sustainability concept followed by those from academia (3.6), consulting (3.0) and contracting (2.2). In terms of factors that significantly influence adoption of sustainability concept during construction, findings from the study revealed that academic qualification (β =2.226, p<0.05) and type of organization (β =1.127, p<0.05) significantly influence adoption of sustainability concept during construction. Practitioners with high academic qualification and those from client organization, exhibited high level of awareness on sustainability concept, this equally influenced their adoption of key elements of sustainability (site planning, energy efficiency, water efficiency, renewable energy, resource conservation, material reuse, indoor environmental quality) during construction. The determination of the level of awareness and adoption of factors contributing to sustainable construction by practitioners will serve as guide to industry practitioners regarding issues to integrate into design and construction project from inception to completion. To improve awareness of sustainable practices in the industry, stakeholders should direct efforts towards organizing seminars, conferences and workshops centered on sustainable construction through the various professional bodies at state and local government levels.Item Barrier Factors Affecting Adoption of Green Building Technologies in Nigeria(Built Environment Journal, 2020-08-21) Amuda-Yusuf, Ganiyu; Raheem, Wasiu Mayowa; Adebiyi, Ranti Taibat; Abdulraheem, Maimunat Orire; Idris, Soliu; Eluwa, Stephen EyinayaGreenhouse gas emission from activities in the built environment is increasing exponentially due to increase in building operations. This study aims at determining factors that affect adoption of Green Building Technologies that normally reduce greenhouse gas emissions. To elicit relevant information, online structured questionnaire forms were administered on practitioners who have been involved in green building development in Nigeria. Mean score ranking was adopted in ranking the barriers to green building technologies, while discriminant analysis was performed to examine how organizations groups (client, consulting, contracting, academia) were distinguished on the barrier factors identified. Findings revealed that, out of the 23 barrier factors considered in this research, lack of institutions to formulate policies and set guidelines (mean score - 4.5) ranked 1st as barrier to adoption of green building technologies in Nigeria. This is closely followed by lack of information about green products (4.0), low level of awareness about sustainability issues (4.0), human resource and client knowledge, lack of knowledge about green building technologies, high cost of green products, while unavailability of sustainable materials and products ranked the lowest (2.7). Only nine factors at 0.05 level of significance entered the discriminant analysis model and emerged as variables with the most significant power in differentiating the organization groupings on the basis of perceived barriers to adoption of green building technologies. The study recommends that there should be strong political will from government, to establish institutions that formulate policies on green building technologies.Item Barrier Factors Affecting Adoption of Green Building Technologies in Nigeria(Built Environment Journal, 2020-06) Amuda-yusuf, Ganiyu; Raheem, Wasiu Mayowa; Adebiyi, Ranti Taibat; Abdulraheem, Maimunat Orire; Idris, Soliu; Eluwa, Stephen EyinayaGreenhouse gas emission from activities in the built environment is increasing exponentially due to increase in building operations.
