Development of an integrative green building rating system for the Ethiopian public building projects using analytic hierarchy process
| Summary: | The design, construction, and maintenance of public infrastructures have a significant impact on the natural environment, and they are responsible for the degradation of scarce natural resources. In this respect, taking green building measures and initiatives has become a strategic concern for long-term development of nations around the world. Consequently, the study aims to develop a benchmarking green building rating system for public building projects in Ethiopia; investigate the current practice, and identify the key benefits and challenges of implementing green building schemes in the public infrastructure sector. To achieve these objectives, a questionnaire survey was employed, and mean score and the analytical hierarchy process (AHP) were used to analyse the collected data from various stakeholders including clients, consultants, and contractors. Data was analysed by using the Statistical Package for Social Sciences (SPSS) to conduct descriptive statistics and MS Excel for the AHP. The findings reveal that the top benefits of green building were identified as using renewable natural resources, enhancing and protecting ecosystem and biodiversity, and improving occupant’s health and comfort. Similarly, the top challenges investigated were lack of adequate incentive for the promotion of green building, inadequate education/training about sustainable design and construction, and lack of awareness and readiness from the public. Moreover, the AHP analysis shows that the critical global weights were Site ecology (20.2%), Energy efficiency (23.33%), Water efficiency (24.7%), Indoor environmental quality (11.94%), and Transport (4.43%). The findings are believed to be helpful for various stakeholders and policy-makers in the Ethiopian construction industry. |
