Abstract
Currently different types of buildings are constructed in Ethiopian Cities especially in Addis Ababa but these buildings were not critically assessed and evaluated from the sustainability points of view because no Sustainable Building Assessment Tool developed so far and no institution is responsible to evaluate and certify the buildings. The research methodology is employed mixed approach types, a purposive sampling for the respondents, and both primary and secondary sources of data. Data was collected through field observation, interviews, survey questionnaires, and document analysis. These data were analyzed by using Statistical Packages for Social Science, MS-Excel, Reliability Analysis and Analytic Hierarchy Process. The findings are based on qualitative and quantitative examination of a rating and assessment systems for sustainable/ green buildings used in both developed and developing nations tailored to the local context. A sustainable building assessment categories and criteria were framed depending upon a consensus-based approach with 100 experienced experts working in the construction sector. The study's findings revealed that there are 68 criteria for the development of a sustainable building assessment for Ethiopia (Ethio-SBAT) under eight assessment categories with relative priority values are materials and resources (18.66%), sustainable sites and ecology (16.92%), energy efficiency (16.78%), indoor environmental quality (12.60%), economic aspects (10.41%), management (10.30%), water efficiency (8.06%), and location and transportation (6.27%) were also identified. Therefore it is crucial to put the developed Ethio-SBAT into practice because it will provide, for instance, good indoor environmental quality for users.
