Assessment on the Use of Sustainable Building Construction Materials: A case of Building Construction project in Jimma town

Abstract

The construction industry is one of the most significant producers of greenhouse gas emissions on a global level. This emission from a building is caused by non-sustainable building materials, which negatively influence the surrounding environment. It is possible to reduce environmental pollution while simultaneously improving the economic perspective, resulting in higher profit margins in the long run. It can be accomplished by improving resource utilization and resulting in less wastage during construction. As a result, the primary goal of study's to assess the uses of sustainable building materials in Jimma town. In this study, both qualitative and quantitative data were employed. The approach of purposive data sampling and primary data collection was obtained from questionnaires and interviews and secondary data obtained from different published and unpublished document. The data were analyzed using an Excel (2010) template, and the reliability of the research was determined by calculating the Cronbach's Alpha coefficient, which measures the degree of consistency. The data was analyzed using the given rate. It was discovered that the extent of applicability of sustainable building materials in Jimma town were less applied, and that among the fourteen features of sustainable building materials, the use of non or less toxic materials was ranked first with the value of (RII=0.701) and among the challenges, the cost and risk-related challenges were ranked first with the value of (RII=0.907). Government-related, technical and performance-related, market-related, awareness and knowledge related challenges ranked one up to five respectively, and under the role of construction professionals: carefully choice materials based on sustainable parameter was ranked first with the value of (RII=0.918). The extent of applicability of sustainable building materials was less extent in Jimma town and among five major challenges cost and risk challenges the primary challenges to implement sustainable materials in Jimma town so that to improve the uses of sustainable building materials in Jimma town; different sectors like; government creating and implementing policy and review or updating urban planning and construction code & professionals should be playing role on selection materials and improve the uses of sustainable building materials
