A practical approach to promoting sustainable development in the construction industry through the use of the LOTUS-Vietnamese green-building assessment tool

In the context of global climate change mitigation, building design optimization is crucial for effective and efficient resource management throughout a project's life cycle. This study addresses the challenge of assessing green building levels using a Vietnamese perspective. A survey of over 220 participants, including investors, consultants, contractors, and other stakeholders, was conducted to identify factors influencing green building assessments. Data analysis, employing SPSS software, explored 57 factors encompassing life-cycle economic optimization, energy and water conservation, material selection, project management, and strategic market benefits. The findings highlight effective energy management as a key determinant shaping sustainable building approaches and assessments. These results offer valuable insights for life cycle cost assessments and environmental impact evaluations during project implementation. Furthermore, the study emphasizes the importance of project developers prioritizing factors that influence the achievement of green building goals based on LOTUS green building rating standards in Vietnam. The predicted results demonstrate that governments should enforce legislation and establish clear green construction regulations to promote environmentally friendly growth, and that construction companies should use environmentally friendly materials and practices in their projects. This research contributes to the knowledge base for scholars, designers, and sustainability experts by systematically identifying factors that influence green building assessments under LOTUS standards.
