【 摘 要 】

In Nigeria, the economicproblem of allocating energy to medicare have long been a major concern andstandardized indices to be used as guidance are non-existent. This paperdetermines energy indices for assessment of how Nigerian hospitals prioritizetheir energy utilization. Systematic field surveys followed by in-depth statistical analysis were adopted.The hospitals were stratified into four categories for the investigation. Then,questionnaires were designed, randomly administered and their responsesgenerated in conversation with workers at 70 hospitals in Nigeria. Results ofthe analysis show that an averagehospital in Nigeria, depending on its category, uses energy as follows: rural66.936kWh/day; urban 343.23 kWh/day; specialist 454.872 kWh/day and teaching 1,944.394 kWh/day. Lighting is shown as acritical energy function and accounts for as much as 15%, 36%, 40.5% and 69.5% of daily energy use in rural, urban,specialist and teaching hospitals, respectively. A productivity based energy performance indicator for each hospitalcategory works out to be 3.346 kWh/bed space/day, 2.367 kWh/bed space/day,4.548 kWh/bed space/day and 19.443 kWh/bed space/day, respectively, for typicalrural, urban, specialist and teaching hospitals. The respective BuildingEnergy Index(BEI) values for the categories of hospitals are as follows: rural 0.13 kWh/m2/day; urban 0.077kWh/m2/day; specialist 0.088 kWh/m2/day and teaching0.277 kWh/m2/day.The low BEIimplies that the buildings have lower rates of sick building syndrome symptoms.Also, auto-generation is predominantly used in all the hospitals, when gridutility supply is unavailable.
