The chapter proposes a conceptual framework for improving sustainability in higher education institutions (HEIs) through cyber community-based facility management. The conceptual framework of the chapter is based on facilities management (FM), the diffusion of innovation, and human development theory. The principles adopted for the conceptual framework are community-based FM, technological innovations, and capabilities approach. The framework is based on the idea that FM can be improved by utilising technology and the community’s capabilities through HEIs characteristics to promote sustainability. The framework’s four essential elements are technology, community capabilities, HEIs characteristics, and sustainability. Technology is used to collect data, monitor and control energy consumption, and improve overall facilities performance. Community capabilities refer to the skills, knowledge, and resources available within a community to engage in sustainable practices and initiatives. Characteristics of HEIs include facility type, public or private designation, location, institution district boundaries, size, student enrolment, age, and infrastructure condition. Sustainability development is achieved through the implementation of green practices, reducing energy consumption, reducing waste, resource efficient and socially inclusive. The framework proposed is appropriate for use by HEIs because they consume a significant amount of energy, emit a significant amount of greenhouse gas emissions, and develop and strengthen students, faculty, and staff capabilities. As a result, they play a critical role in promoting sustainability. The chapter concludes by emphasising the importance of further research on the conceptual framework’s implementation and effectiveness in promoting sustainability.
