    Assessment of Electrical Energy Consumption in Some Selected Tertiary Institutions Administrative Buildings in Niger State

    High electrical energy consumption in public buildings and institutions poses a significant challenge, particularly in developing countries like Nigeria. Inadequate empirical studies on building energy use have resulted in a lack of electrical energy data, especially in tertiary institutions where bulk metering is common. This study aimed to assess the electrical energy consumption in selected administrative buildings of tertiary institutions in Niger State, with the goal of reducing electrical consumption and improving energy efficiency. Experimental data collection involved direct field measurements using a real-time Efergy wireless energy (EW4500) monitoring device. Current transformer sensors were attached to the main distribution panels of the administrative buildings at the Federal University of Technology Minna, Niger State Polytechnic Zungeru, and Niger State College of Education Minna. The objectives included evaluating electrical energy consumption, comparing total consumption across buildings, and analyzing energy consumption patterns. Results indicated that the Senate building at FUT Minna had the highest consumption rate at 2604.7 KWh/m², followed by Niger State Polytechnic Zungeru at 2579.1 KWh/m², both exceeding the global benchmarks of 128 to 130 kWh/m² set by the Chartered Institute of Building Services Engineers (CIBSE) and the Building Energy Efficiency Guideline for Nigeria (BEEGN). In contrast, COE Minna’s administrative building, with consumption levels averaging 1579.1 KWh/m², generally fell within these benchmarks. The elevated energy consumption at FUT Minna and Niger State Polytechnic Zungeru was primarily attributed to operational inefficiencies, such as the continuous operation of HVAC systems and equipment during non-essential hours, even when buildings were not fully occupied. Hourly consumption patterns revealed peak usage during early working hours, with significant seasonal variations; however, both FUT Minna and Niger State Polytechnic Zungeru exhibited high energy use during off-peak periods, reflecting poor energy management practices. To address these inefficiencies, the study recommends conducting comprehensive energy audits and installing energy-efficient appliances at FUT Minna and Niger State Polytechnic Zungeru. Additionally, implementing smart metering, occupancy sensors, and optimized HVAC controls would significantly enhance monitoring and reduce energy consumption. These measures are critical for improving energy efficiency and ensuring sustainable operations in both institutions.

    Effects of Reprography and Use of Electronic Resources on Book Buying by Students of Tertiary Institutions in Niger State
    (Journal of Applied Information Science and Technology, 2017) Alhassan, J.A; Yusuf, H.; Abduldayan, F.J.; Akor, P.U.
    This study examined effects of reprography and use of e-resources on book buying by students in selected tertiary institutions in Niger state. The objectives of the study were to determine: the rate of other means of reproducing work on book trade, the benefits of using e-resources, challenges of book trade in Niger state and to find out the rate of using e-resources by the students of tertiary institutions in Niger state. Descriptive survey was used for the study in three selected tertiary institutions in Niger state, these were Federal University of Technology (FUT) Minna, Federal Polytechnic, Bida and Federal College of Education, Kontagora. The population of the study consisted of students of the institutions which was 23,061. 300 respondents were sampled using Simple random technique, that is, 100 respondents from each institution. Structured questionnaires were used to gather data while data collected was analyzed using frequency count and simple percentages. Findings revealed that the respondents photocopy book materials and also make use of electronic resources when searching for information, but that majority of the respondents do not buy books. The study recommends that students should cultivate the culture of buying books, rather than photocopying so as to uphold both the standard and professional excellence in higher institutions. The study recommended that electronic information resources should be made available and students should effectively utilize the needed.
