On 29 April 2026, a Room Data Survey (RDS) was conducted at the Faculty of Electronics and Computer Technology and Engineering (FTKEK) to evaluate the indoor environmental conditions of the faculty building. The RDS Audit Team carried out on-site measurements at selected rooms and areas across different floors. Four key parameters were measured: room temperature, relative humidity, carbon dioxide (CO₂) concentration, and illuminance level. The collected data were analysed to assess occupants’ comfort and identify areas for improvement in indoor environmental quality.

A total of 39 rooms were assessed. The survey found that 90% of the rooms recorded relative humidity within the recommended range, while 10% exceeded 70%. For room temperature, 26% were within the recommended range, while 51% recorded temperatures above 26°C. The survey also assessed lighting and indoor CO₂ levels. For illuminance, 49% of rooms were within the specified range, while 36% were underlit. Meanwhile, only 5% of rooms recorded CO₂ levels above 1,000 ppm, with most rooms recording lower concentrations.

The RDS findings provide valuable information to support FTKEK in improving indoor comfort, building performance and energy management, contributing towards a healthier and more sustainable faculty environment.

Overall Energy Consumption Trend

Energy consumption at the Faculty of Electrical and Electronic Engineering Technology (FTKEK) shows a changing pattern from 2023 to 2026. Annual electricity consumption increased from 1,214,410.50 kWh in 2023 to 1,243,276.50 kWh in 2024, and further to 1,309,155.31 kWh in 2025. For 2026, the available data from January to June recorded 663,270.25 kWh. Monthly consumption during this period ranged from 89,815.52 kWh in February to 154,559.75 kWh in April.

Higher Energy Use in the First Half of 2026

The first six months of 2026 recorded the highest January–June consumption among the years compared, representing an increase of approximately 23.8% compared with the same period in 2025. The increase was particularly noticeable in April and June 2026, where consumption rose by approximately 67% and 33%, respectively, compared with the same months in 2025. The data also indicates that energy consumption had already started increasing towards the end of 2025.

Possible Factors Affecting Energy Consumption

Several operational and environmental factors may have contributed to the higher electricity demand. FTKEK experienced a significant increase in undergraduate student numbers beginning in Semester 1 of the 2025/2026 academic session. Higher building occupancy  increase the use of classrooms, laboratories, lighting, equipment and air-conditioning systems.  The period between January–June 2026, due to La Nina phenomenon, with hot and dry weather conditions, which may have increased cooling and air-conditioning requirements.

Impact on Electricity Cost

The increase in electricity consumption was accompanied by a significant rise in energy expenditure. From January to June 2026, FTKEK recorded an electricity cost of approximately RM457,929, compared with RM281,313 for the corresponding 2025 data, an increase of about 62.8%. Monthly costs in 2026 ranged from RM65,956 in January to a high of RM93,908 in March. This highlights the importance of managing not only electricity consumption but also the financial impact of energy use.

Building Energy Performance

FTKEK also monitors its Building Energy Index (BEI), which represents the amount of energy consumed per square metre of building floor area over a year. The BEI provides a useful indicator for comparing building energy performance between years. However, the 2026 BEI should be interpreted carefully because the current figure represents only data up to June 2026 rather than a complete year.

Energy Efficiency and Carbon Emissions

Further analysis using Load Factor (LF), Seasonal Energy Efficiency Ratio (SEER) and CO₂ emissions provides additional insight into FTKEK's energy performance. The report indicates that higher load factors are generally associated with higher SEER values, reflecting more efficient operation, while higher electricity consumption also results in increased CO₂ emissions. For example, August 2025 recorded the highest listed load factor of 0.60, SEER of 9.42, and CO₂ emissions of 135.22 tonnes. These indicators support FTKEK's continued efforts to monitor energy efficiency, control operating costs and reduce the environmental impact of its facilities.
