Evaluating a driving index of nonresidential green building implementation for sustainable development in developing countries from a Vietnamese perspective

The purpose of this study is to evaluate a quantitative driving index for implementing green building in Vietnam as a case study in developing countries. Using literature review and expert interviews, 19 driving forces affecting green building implementation were identified in the Vietnamese context. Via obtained data from a questionnaire survey, four principle factors were grouped from defined drivers. The fuzzy synthetic evaluation method was utilized to develop a driving index (DI) for developing the green building in Vietnam. DI model indicated that environmental impact is the most crucial group for green building implementation in Vietnam. Apart from this, the result of the comparative analysis also indicated that most driving forces for adopting green building in developing countries related to environmental and social problems. These results provide the decision-makers with a comprehensive tool to assess the expectations for green building implementation in both Vietnam and other developing countries.
