University-Wide Energy Efficiency Planning

Universitas Islam Sultan Agung (UNISSULA) has established an institutional Energy Efficiency Plan to reduce overall energy consumption across the university.

The plan is formalised through Circular Letter No. 8392/J/SA/IX/2025, dated 4 September 2025, and applies to all faculties, units, buildings, and university facilities.

The circular explicitly states that UNISSULA establishes an Energy Efficiency Plan in order to improve energy efficiency, support sustainable development, and reduce overall energy consumption across the university.

Reducing Overall Energy Consumption

The main objective of the plan is to reduce energy consumption at the institutional level rather than only within individual buildings or units.

UNISSULA applies the plan across:

• faculties;
• administrative units;
• university buildings;
• operational units; and
• other university facilities.

This university-wide scope ensures that energy-efficiency measures are implemented as part of a coordinated institutional approach.

Energy-Efficiency Measures

The plan identifies a number of practical measures to reduce energy consumption.

These include:

• use of LED lighting;
• use of energy-efficient air-conditioning;
• use of energy-efficient electrical equipment;
• optimisation of natural lighting;
• optimisation of natural ventilation;
• improvement of building efficiency through renovation;
• use of solar panels; and
• switching off lighting and electronic equipment when they are not in use.

These measures address both technical efficiency and daily operational behaviour.

LED Lighting

UNISSULA promotes the use of LED lighting as part of its energy-efficiency plan.

LED systems require less electricity than conventional lighting and also have longer operating lifetimes.

The use of LED lighting therefore supports reductions in electricity consumption across classrooms, offices, corridors, laboratories, and other university spaces.

Energy-Efficient Air Conditioning and Electrical Equipment

The plan also includes the use of more efficient air-conditioning systems and electrical equipment.

Air-conditioning represents a significant source of electricity demand in many university buildings.

By using energy-efficient systems and operating them responsibly, UNISSULA seeks to reduce unnecessary electricity consumption while maintaining appropriate indoor comfort.

Natural Lighting and Ventilation

The Energy Efficiency Plan also promotes greater use of natural lighting and ventilation.

Natural daylight can reduce dependence on artificial lighting during daytime operation.

Natural ventilation can also reduce the need for mechanical cooling in suitable spaces.

These measures help lower building energy demand while supporting more sustainable building operation.

Energy-Efficient Renovation

Improvement of existing buildings through renovation forms another part of the plan.

Renovation provides an opportunity to:

• replace inefficient lighting;
• improve ventilation;
• improve natural daylighting;
• install more efficient electrical equipment; and
• improve the overall energy performance of existing buildings.

This links the Energy Efficiency Plan with UNISSULA’s broader approach to upgrading existing campus buildings.

Renewable Energy Through Solar Panels

UNISSULA also includes the use of solar panels within its Energy Efficiency Plan.

The use of solar energy helps reduce dependence on conventional electricity sources and supports cleaner campus energy use.

The inclusion of solar panels in the plan demonstrates that overall energy reduction is supported not only by conservation measures, but also by the increased use of renewable energy.

Responsible Use of Energy

Operational behaviour is also an important part of the plan.

UNISSULA requires lights and electronic equipment to be switched off when no longer needed.

This helps prevent unnecessary electricity consumption from:

• lighting;
• computers;
• air-conditioning;
• office equipment; and
• other electrical devices.

Such measures complement technological improvements by encouraging responsible energy use across the university community.

Periodic Evaluation of Energy Consumption

The plan also establishes a process for reviewing energy consumption.

Energy use in university units and facilities is evaluated periodically to identify:

• areas of high energy consumption;
• opportunities for energy saving; and
• areas where further efficiency improvements can be made.

This makes the plan more than a list of efficiency measures because it includes an ongoing evaluation process.

Continuous Improvement

The results of energy-use evaluations are used to support continuous improvement.

The policy states that evaluation results are used to increase energy efficiency and reduce overall university energy consumption on an ongoing basis.

UNISSULA’s approach can therefore be summarised as:

implement energy-efficiency measures → evaluate energy use → identify opportunities for improvement → implement further efficiency measures

This establishes a continuous cycle of energy-performance improvement.

Integration with Building and Campus Development

The Energy Efficiency Plan is also connected with other campus sustainability measures.

Energy efficiency is supported through:

• efficient building renovation;
• LED lighting;
• natural daylight;
• natural ventilation;
• efficient air-conditioning;
• efficient electrical equipment;
• renewable energy; and
• responsible operational practices.

This integrated approach helps reduce energy consumption across both existing infrastructure and future campus development.
