This study examined the sustainable practices of the Bulacan State University (BulSU) Hostel and Dormitory and their alignment with selected targets of the United Nations Sustainable Development Goals (SDGs). Framed within the concept of the hostel as a living laboratory, the research explored how day-to-day operations reflect institutional commitments to sustainability. A convergent mixed-methods design was employed, integrating quantitative survey data with qualitative insights from interviews and field observations. Respondents included student residents, faculty members, and hostel staff. Results showed that the hostel has made substantial progress in areas such as water access, sanitation, and energy efficiency—highlighting its contribution to SDG 6 (Clean Water and Sanitation) and SDG 7 (Affordable and Clean Energy). However, gaps remain in SDG 12 (Responsible Consumption and Production), particularly in solid waste management and the absence of formal green procurement guidelines. While awareness of the SDGs was universal among respondents, many demonstrated only a surface-level familiarity, with limited opportunities for deeper engagement or structured sustainability education. Qualitative findings pointed to actionable strategies, including the installation of sensor-driven water fixtures, expansion of solar power infrastructure, development of composting systems, and implementation of campus-wide green purchasing policies. Respondents also emphasized the importance of enhancing resident awareness through regular campaigns and integrating sustainability themes into hostel routines. In conclusion, while the BulSU Hostel demonstrates a strong foundation in core sustainability areas, more intentional efforts in behavioral education, monitoring systems, and policy alignment are needed. The study reinforces the hostel’s potential to serve as a replicable model for other academic institutions working to localize and live out the SDGs.
