Abstract

The study was carried out in order to know the annual energy utility indices and also the energy consumption hierarchy in Public Research Institutes with the hope of introducing potential energy saving policy options to reduce the amount of energy consumed in the different sections of energy used in public buildings. Energy audit was conducted in the Research Institutes using the method (but with slight modification) Pearson Engineering used for the Engineering Energy Audit of Lowell Hall of University of Wisconsin, USA, July, 2004.


The annual energy utility indices for the Research Institutes are: Cooperative Information Network (28.3 KWH/m2/year), Centre for Space Science Education (160 KWH/m2/year), Centre for Gender and Social Policy Studies (155 KWH/m2/year), Central Science Laboratory (203 KWH/m2/year), Centre for Energy Research and Development (30 KWH/m2/year), Centre for Industrial Research and Development (65 KWH/m2/year), Drug Production and Research Unit (355 KWH/m2/year), National History Museum (366 KWH/m2/year), Institute of Ecology and Environmental Studies (188 KWH/m2/year), Regional Centre for Training in Aerospace Surveys (113 KWH/m2/year), Atomic Research and Information Analytical Laboratory (86 KWH/m2/year), National Centre for Technology Management (17 KWH/m2/year). Using 100 KWH/m2/year as threshold for energy use efficiency, six out of the twelve Research Institutes fall above the line and using 150 KHW/m2/year as the energy use efficiency threshold, four out of the total twelve falls above the line. It was also found out that not less than half of the total energy consumed in Nigerian Public Research Institutes is used in cooling (Air-conditioning, Refrigerating and Freezing). Also, that more energy is used for cooling than for office equipments, more energy is used for office equipments than for lighting, more energy is used for lighting than for laboratory (special) equipments, more energy is used for laboratory (special) equipments than for ventilation, and more energy is used for ventilation than for heating.
The study showed that the bulk of the energy used in public research institutes is used in cooling. It is therefore necessary that the Research Institutes should carefully study the equipments used in cooling and retrofit accordingly in order to reduce the energy consumed in cooling so as to reduce cost and improve productivity and overall efficiency.
