7.2.5. Energy Wastage Identification

IGU conducts regular energy analyses and makes technical interventions in areas where they are needed as part of its efforts to reduce energy waste. In this regard, detailed data on energy usage has been obtained and improvement processes have been initiated with the “Building Automation System” project launched in 2023. Especially with the system applied to the Tower Campus, lighting, fire detection, and mechanical systems have been revised, and efficiency has been increased with dimmer-equipped fixtures and daylight sensors. In the six months prior to the automation system being put into operation, electricity consumption was measured at 1.352.118,8 kWh, while in the following six months, this value was recorded as 1.422.840,4 kWh. Although total consumption increased due to the expansion of the floor area from 116.080.1 m² to 138.313.6 m² during the same period, CO₂ emissions per m² decreased by 12%. This result demonstrates that energy waste identification and intervention processes were effectively implemented.

7.2.5.1. Analysis of Consumed Energy

Energy consumption is tracked through relevant billing documents and is regularly recorded at the end of each month on a digital platform known as the QDMS Integrated Managament System. Consumption data is analyzed through this system to make assessments regarding sustainability targets. Among the types of energy used at the university, the most intensively used resource is electrical energy. Block-based electricity consumption data for 2024 has been analyzed in detail, and the total consumption has been determined to be 4.523.414,21 kWh. In the analysis conducted by month and building, A Block (Rectorate and administrative units) and K Block (numerous faculties, laboratories, and high-rise buildings) stand out as the buildings with the highest consumption rates. This high energy consumption is expected given the intensive use of these areas and the technical infrastructure they house. However, these data demonstrate that the university is monitoring its energy consumption intensity, identifying high-consumption areas, and has the potential to develop targeted energy efficiency measures. Regular measurement and monitoring enable interventions to prevent energy waste to be planned in a more effective and strategic manner.

When examining natural gas consumption data for 2024, it can be seen that consumption is high during the winter months (January: 44.874 m³, February: 39.709 m³, March: 36.311 m³, December: 45.005 m³). These four months comprise the majority of total consumption. During the spring and summer months, natural gas consumption decreases significantly, particularly in July, August, and September, where it remains below 100 m³. This indicates that heating needs are correlated with seasonal effects. A total of 207.392 m³ of natural gas was consumed, and these data reveal that the energy usage varies according to the months and weather conditions.

*The values are expressed in m³.

When comparing fuel consumption amounts for 2023 and 2024, it can be seen that there has been an increase in electricity and natural gas consumption and a decrease in gasoline consumption. Electricity consumption rose from 3.901.005,16 kWh in 2023 to 4.523.414,21 kWh in 2024. One of the main reasons for this increase is the expansion of the university's campus and the start of additional academic activities. Similarly, natural gas consumption increased from 123.936 m³ in 2023 to 207.392 m³ in 2024. This increase was influenced by colder winter months, heating systems being activated one month earlier, increased weekend activities in the buildings, and the additions of radiators/central heating systems.

A decrease in gasoline consumption from 10.600,32 liters to 7.692,00 liters has been observed. This decrease can be considered an indicator of the transition to more efficient vehicle use and an increase in the number of low-emission vehicles in line with sustainability policies. Diesel consumption, on the other hand, showed a very slight increase from 24.692,56 liters to 25.112,00 liters; this situation can be associated with the intensity of service vehicle usage.

The table below shows the amount of energy consumed by energy type in 2024.

Gasoline	7.692,00	Litre
Diesel	25.112,00	Litre
Natural Gas	207.392,00	m3
Electricity	4.523.414,21	kWh
