This chapter carries out an investigation on the consumption of energy and emission of CO₂ in 16 Students’ halls of residence (hostels) in Lagos, Nigeria, to gain an understanding on the status, impacts and performance of energy use in public student residences. The use of energy in Nigeria was highlighted and the continuously evolving built environment was shown to have an impact on the electricity infrastructure of the nation. Residential buildings were shown to significantly impact energy supply around the world. Methods of benchmarking were applied for the identification of variables capable of impacting on the consumption of energy in the buildings, these methods also identified the variables that significantly correlated with the energy consumption. The energy usage intensity (EUI) was characterized and with EUI acting as an indicator for building energy performance (BEP), the derived annual benchmark range of EUI was derived and given as 93.61–147.1kWh/m². The CO₂ emission levels were calculated using an emission factor and correlation analysis was carried out to show that floor area, number of occupants and number of rooms all had significant correlation with the CO₂ emissions.
