Energy Profile and Energy Consumption in Hotels in the Warm Humid Climate of South East Nigeria
Abstract
Preliminary survey on the energy profile and usage in selected hotels in the warm humid climate of South East Nigeria are presented. The survey shows the various energy sources utilized by the hotels. A detailed analysis of a number of physical and operational factors that may influence the energy use in the hotels is being carried out. The statistical methodology employed to determine the magnitude of effects of the factors; utility bill for one year, age of building, worker density, average monthly occupancy level, power for lighting, power for water heating, power for cooling, air-conditioning, lifts, kitchen equipment, gross floor area, year of construction, hotel class, weather, etc on energy use is described. The study would establish the energy use index (EUI) of the hotel buildings and determine the energy saving potential of the hotel buildings under the prevailing climatic conditions. The study reveals huge potentials for integrating renewable energy technology such as solar outdoor lights, solar water heaters and solar cookers to replace fuel wood in the hotels. It is anticipated that the results of the full study will lead to the development of an energy rating scheme and building energy code for hotel buildings in Nigeria.
