This paper investigates the synergy between Vaastu Shastra, an ancient Indian architectural science, and modern sustainable building practices. By examining how Vaastu principles can enhance environmental sustainability, the study proposes a framework for designing residential and commercial buildings that align with both traditional wisdom and contemporary ecological standards. Key areas of focus include the optimal orientation of buildings, the use of natural materials, energy-efficient design, and the incorporation of green spaces. Through a detailed review of literature, case studies, and practical applications, this research highlights how Vaastu Shastra can contribute to creating buildings that are not only environmentally sustainable but also in harmony with natural forces, promoting well-being and ecological balance.
