Economic efficiency of renewable energy integration in university campuses

Abstract

The growth of energy consumption in higher education institutions and the increase in utility expenditures intensify the need to identify economically efficient solutions in the management of university infrastructure. The purpose of this article is to assess the economic feasibility of transforming university campuses into green campuses during the period 2025–2031 under conditions of rising energy consumption and increasing utility costs. The implementation of renewable energy sources (RES) and sustainable infrastructure solutions as instruments for enhancing the financial sustainability of universities.

The research method is based on a systemic economic approach, within which the key performance indicator is the specific energy consumption of the campus (kWh/m²). A mixed methodology is applied, including multiple linear regression analysis, a student survey, and a case study of L.N. Gumilyov Eurasian National University.

The results indicate that the implementation of RES and the development of waste management systems make the greatest contribution to reducing specific energy consumption and operating costs. These measures generate a long-term budget savings effect, improve infrastructure energy efficiency, and strengthen the financial sustainability of the educational institution.

Conclusions – the green campus model can be considered as an investment mechanism for university development, ensuring cost reduction, increased energy independence, and enhanced competitiveness, especially for countries with severe climatic conditions, including Kazakhstan.

At the same time, building an effective green campus model requires an interdisciplinary approach that integrates both the engineering and technical aspects of implementing renewable energy sources (RES) and the socio-educational mechanisms for fostering environmental culture. It is essential to understand which factors—technological, behavioral, or managerial—play a decisive role in successfully embedding sustainability solutions into university infrastructure.

The aim of this article is to develop a comprehensive model for transforming university campuses into green ones, based on a systems analysis of energy, environmental, and educational components. The study will examine key infrastructure parameters, levels of environmental awareness among stakeholders in the educational process, and institutional practices in sustainable development management. This approach will help identify the most effective strategies for transforming universities into sustainable educational ecosystems.
