Highlights • We studied the energy consumption trend in the Nigerian hotel industry. • We discovered that there was significant correlation between energy consumption and total floor area, number of guest rooms, number of equivalent guest rooms and number of employees. • We established that that the Energy consumption per unit area of hotels in Nigeria is below average when compared to the values obtained in other countries. • We established a benchmark such that annual energy consumption per unit guestroom shouldn’t exceed 40.278MWh/guestroom while the annual energy consumption per unit equivalent guestroom shouldn’t exceed 62.861MWh/equivalent guestroom in order to prevent excessive CO2 emission into the atmosphere.

Abstract Nigeria has one of the lowest electricity consumption per capita in Africa and this is because the power grid capacity has not been able to meet the ever increasing demand for electricity. To remain in business, several business enterprises rely on captive generation of electricity; thus, the hospitality industry is not left out of this experience. Primarily, this study evaluates the energy consumption trend in the Nigerian hotel industry. The energy utilization is modeled in order to appraise its influence on the emission level of the diesel generators, which is the major source of electricity supply in Nigeria. The linear regression method is employed for the characterization of the energy utilization index. Also, correlation analysis is employed to investigate the interdependence of carbon footprint and normalized energy consumption. Results show a significant correlation between energy consumption per unit guest room and the carbon dioxide emission level. This work develops a carbon footprint protocol for the hotel industry in Nigeria by recommending that the annual energy consumption per unit guestroom should be kept at a value not more than 40.278MWh/guestroom while the annual energy consumption per unit equivalent guest room should be less than 62.861MWh/equivalent guestroom.
