Abstract

This study assesses the environmental impacts of energy consumption of 24 hotel buildings in Enugu Metropolis. Structured questionnaire was administered to the hotel managers in order to collect energy consumption pattern. Measurements were carried out to reproduce the floor plans of the hotels in-order to determine the floor areas. The breakdown of energy consumption showed that diesel and petrol generator sets dominated for regular and 24hours electricity supply. The average Building Energy Index (BEI) of 405.73Kwh/m 2 /yr was derived based on unit floor area. The result further showed that average CO 2 emissions from consumption of grid electricity to be 2936.06KgCO 2 e/Kwh/yr, and 294817.44KgCO 2 e/litre/yr and 1546.69KgCO 2 e/litre/yr, respectively for diesel and petrol. The study concluded that there is need to reduce dependence on fossil fuel consumption of the hotels and therefore recommends the encouragement of low energy and energy efficient hotel building designs in the study area. Key Words : fossil fuel, carbon emission, hotel buildings, building energy Index (BEI), energy efficiency

对尼日利亚埃努古大都会酒店能源相关碳排放的初步评估

本研究评估了埃努古城区24座酒店建筑的能耗对环境的影响。通过对酒店管理人员进行结构化问卷调查，了解酒店的能源消费模式。测量进行了再现酒店的平面图，以确定地板面积。能源消耗的分类显示，柴油和汽油发电机组在日常和24小时电力供应中占主导地位。基于单位建筑面积计算得出平均建筑能耗指数(BEI)为405.73Kwh/ m2 /yr。结果进一步表明，电网用电平均二氧化碳排放量为2936.06KgCO 2 e/Kwh/年，柴油和汽油分别为294817.44KgCO 2 e/升/年和1546.69KgCO 2 e/升/年。该研究的结论是，需要减少对化石燃料消耗的依赖，因此建议在研究区域鼓励低能耗和节能的酒店建筑设计。关键词:化石燃料，碳排放，酒店建筑，建筑能源指数，能效
