Abstract

This study focuses on designing an efficient energy utilization protocol for the University of Lagos Senate office building, to ensure the reduction of energy consumption, reduce the cost of power and also ensure energy efficiency. Pre-retrofitting, the energy consumption cost for the UNILAG senate office building was calculated to be ₦20, 236, 962 i.e. 776.78 EUI (kWh/m²/y) using the appliance approach. The impact of various retrofitting methods was also simulated and measured utilizing BIM tools such as Autodesk Maya, Autodesk Revit and Autodesk Insight. This resulted in an estimated reduction in energy consumption cost to between ₦19,304,038.05 and 18,549,199.3 post retrofitting, this translates to about 712 EUI (kWh/m²/y). Results show that a 4.61-8.34% reduction in energy usage for the senate house can be achieved using the methods proposed in this research.
