Awareness and Adoption of Green Building Principles Among Construction Professionals in Ibadan, Nigeria
Subject area: Science,Engineering and Technology · Area of research: Construction and Project Management
Abstract
This study aimed to determine the extent to which construction professionals in Ibadan, Nigeria, are aware of and apply green building principles. The study adopted a cross-sectional survey design. The target population comprised construction professionals involved in building design, construction, management and project delivery in Ibadan. A convenience sampling procedure was used to recruit respondents across the identified professional categories. A total of 115 questionnaires were administered, of which 100 were completed and valid for analysis, representing a response rate of 87.0%. Respondents indicated their level of agreement with each statement on a five-point Likert scale. Data were analysed using frequencies, percentages, mean scores and ranking. The results showed relatively high reported awareness of green building principles, with mean scores of 4.07 for both familiarity with green building concepts and understanding of sustainable building design principles. The five practical adoption indicators recorded mean scores ranging from 3.33 to 3.97, with an average item mean of 3.74. Water conservation recorded the highest adoption-related mean (3.97), followed by waste reduction (3.94) and energy-efficient design (3.84). However, respondents perceived the overall level of green building adoption across the Ibadan construction industry less favourably, with a mean score of 2.90. The findings therefore indicate a descriptive difference between reported awareness and reported adoption-related practices, while also suggesting that broader industry-wide adoption may remain limited. The study recommends strengthening project-level implementation guidance, practical capacity and supportive conditions for the wider application of green building principles.
