Termiz State University implements a comprehensive institutional energy efficiency plan aimed at reducing overall energy consumption, improving resource productivity and strengthening the environmental sustainability of its academic, administrative, residential and research facilities. Integrated into the university's 2024–2027 Institutional Development Strategy, the plan establishes a coordinated framework for energy conservation through modernisation of electrical infrastructure, energy-efficient building technologies, intelligent monitoring systems, thermal optimisation and responsible energy management. Its principal objective is to minimise unnecessary energy expenditure while maintaining appropriate conditions for education, scientific research and university operations.
The institutional plan prioritises the systematic replacement of conventional electrical equipment with energy-efficient technologies across university facilities. By 2025, the university's technical inventory included 61,139 appliances and equipment units, of which 52,806, representing 86.37%, were classified as energy-efficient. This substantial adoption of efficient technologies encompasses lighting systems, air-conditioning equipment, electricity meters, automatic control panels, computers, laboratory equipment and other operational devices. The programme provides a practical foundation for reducing electricity demand and improving the efficiency of energy-consuming activities throughout the university.
Lighting modernisation constitutes one of the principal components of the energy conservation programme. The university's 2025 inventory identified 48,300 energy-efficient indoor lighting fixtures, alongside 965 energy-efficient outdoor lighting units and 340 motion-sensor lighting devices. The systematic adoption of LED lighting and automatic switching technologies is designed to minimise electricity consumption while maintaining appropriate illumination in classrooms, laboratories, libraries, administrative offices, university residences and outdoor public spaces. Motion-sensitive lighting and automated controls further limit unnecessary electricity use in intermittently occupied areas, contributing to more efficient campus operations.
A complementary priority involves improving the energy performance of heating, cooling and electrical distribution systems. The university has introduced energy-efficient air-conditioning equipment, modern electrical control devices and power-factor correction systems to improve operational efficiency and reduce avoidable electrical losses. The 2025 equipment inventory recorded 864 energy-efficient air-conditioning units, together with 45 smart electricity meters and sub-meters and 112 energy-efficient automatic breakers and control panels. Power-factor correction equipment with capacities of 150 kVAr and 300 kVAr has also been installed within the university's water-supply electrical infrastructure. These interventions support improved electrical system management and help control the operational costs associated with university facilities.
Building-envelope optimisation represents a further strategic component of the university's energy efficiency plan. Existing buildings incorporate thermal insulation measures, including basalt-based insulating materials, glass-wool roof insulation and thermally efficient window and door systems. Such improvements are particularly relevant to Surkhandarya's climatic conditions, characterised by substantial summer cooling requirements and seasonal heating demand. By reducing heat transfer and improving indoor thermal stability, these technologies are intended to decrease energy requirements for air conditioning and heating while maintaining comfortable conditions for students and university employees.
The university has also expanded the application of smart-building technologies and automated energy-management systems. During 2025, smart-building elements were recorded across 22 university facilities, encompassing approximately 97,677.44 m² of building space. These facilities incorporate varying combinations of automated lighting, energy monitoring, operational controls and indoor environmental management. The integration of digital technologies enables more systematic supervision of energy-consuming equipment and supports the identification of opportunities to improve building performance.
Thermal energy conservation is reinforced through the deployment of solar water-heating technologies. At Student Dormitory No. 3, ten solar thermal collectors with individual capacities of 200 litres provide a combined hot-water storage capacity of 2,000 litres. The installation reduces reliance on conventional electrical or fuel-based water heating and demonstrates the practical integration of energy-efficient solutions into student accommodation infrastructure. The university's energy management programme also incorporates improvements to thermal distribution systems and water-heating equipment to reduce avoidable energy losses.
The effectiveness of these measures is supported by the university's commitment to systematic energy auditing, consumption monitoring and institutional accountability. Rector's Order No. 182-U of 29 September 2024 established responsibilities for energy-efficiency oversight, energy audits and monitoring of institutional resource consumption. The audit framework covers academic buildings, laboratories, administrative premises, student accommodation, lighting infrastructure and heating and cooling equipment. Energy assessments are used to identify inefficient systems, establish priorities for technical improvements and develop measures for reducing unnecessary energy use.
Monitoring activities include the examination of electricity billing records, smart-meter information, technical equipment inventories and renewable-energy monitoring systems. The university's digital energy infrastructure supports the collection and assessment of operational information, enabling responsible departments to examine electricity demand and make informed decisions concerning equipment upgrades and energy conservation.
The university's electricity procurement data demonstrates a reduction in dependence on purchased grid electricity. Between 2023 and 2025, annual electricity purchases from the public grid decreased from 2,120,000 kWh to 1,840,000 kWh, a reduction of 280,000 kWh, or approximately 13.2%. This development occurred alongside the implementation of energy-efficiency measures and the expansion of university-owned renewable electricity generation.
During 2025, Termiz State University directly utilised 3,010,000 kWh of electricity generated by its solar photovoltaic systems, alongside 1,840,000 kWh purchased from the public grid. Total recorded electricity consumption amounted to 4,850,000 kWh, with renewable electricity accounting for 62.06% of the annual electricity supply. These figures demonstrate the growing role of renewable energy in the university's electricity management framework while establishing a quantitative basis for assessing consumption patterns and future efficiency improvements.
The university's energy efficiency plan distinguishes between reducing energy demand and increasing the proportion of electricity supplied from renewable sources. Improvements in lighting, heating, cooling, electrical equipment and building insulation are intended to reduce the energy required for university operations, whereas renewable-generation projects address the environmental characteristics and sourcing of that energy. The combination of these approaches strengthens the institution's capacity to manage resource consumption sustainably and reduce its reliance on carbon-intensive energy sources.
Institutional oversight, periodic energy reviews and continued technological modernisation provide the operational foundation for implementing the energy efficiency plan. The university prioritises the assessment of inefficient equipment, improvement of building performance, expansion of automated controls and adoption of technologies that support more effective resource management. These measures are integrated into its broader sustainability strategy, connecting operational efficiency with financial responsibility and environmental protection.
Termiz State University's approach reflects a long-term institutional commitment to improving energy performance across its facilities and activities. Through coordinated energy auditing, modern electrical technologies, thermal efficiency improvements, intelligent monitoring and responsible consumption management, the university establishes a systematic framework for reducing avoidable energy use and strengthening the sustainability of campus operations.
By maintaining and implementing this comprehensive energy efficiency plan, Termiz State University contributes to Sustainable Development Goal 7: Affordable and Clean Energy, promoting the efficient utilisation of energy resources, reducing unnecessary operational expenditure and advancing the development of a more sustainable, resource-efficient and environmentally responsible university infrastructure.
