ABSTRACT
Apparently, Nigeria is struggling with the developmental issues of the incessant power outage and lack of energy services. The primary sources of energy for office building are from national grid and gasoline generators. However, the former is not reliable and the latter is unsustainable; hence, the need to explore energy efficiency strategies to cut down the energy demand for cooling office building in Nigeria is unavoidable. This dissertation aimed to assess the energy efficiency or performance index of the Nigerian Universities’ senate buildings in the north-eastern region (dry sub-humid climate). The research employed a case study approach, construction of baseline model with the Revit architecture software and applied Autodesk’s Ecotect building analysis software to evaluate the energy performance of the senate building as built. Three local case studies and one foreign case study were selected such as university administrative building of Modibbo Adama University of Technology, Yola (MAUTECH), senate building of Abubakar Tafawa Balewa University, Bauchi (ATBU), university administrative building of Gombe State University, Gombe (GSU) and the Chancellery office building of University Kebangsaan (UKM), Malaysia.
