Rwanda's rural schools in the highlands face challenges related to infrastructure, including inadequate access to clean water and energy sources, which negatively impact students' health and learning environments. A mixed-methods approach was employed, involving a survey of 120 rural Rwandan teachers. Quantitative data were analysed using descriptive statistics to identify themes among responses. Teachers overwhelmingly supported the implementation of solar panels for energy and rainwater harvesting systems for water management in school construction projects. The findings suggest that incorporating eco-friendly features into school buildings can significantly improve the sustainability and functionality of rural schools. School administrators should prioritise funding for sustainable infrastructure development, while teachers' recommendations on specific technologies could be integrated into curriculum planning.
