| Abstract |
This study investigated exploratory research on energy consumption model of elementary schools by using an explanatory variable, number of classes and responsive variable, total annual energy consumption. Totally 18,539 data set of energy consumption in elementary schools are acquired for the analysis. After excluding abnormal data, 18,363 data set was used for the least square method for number of classes and total annual energy consumption. As the result of the study, the developed linear regression model is as follow: Annual total energy consumption (TOE) = 2.6259·X + 15.5 (X: number of classes). The coefficient of determination of this model is 0.7336. The derived coefficient of determination is slightly lower than required value of 0.75 by ASHRAE 2013. However, considering various conditions of 18,363 elementary schools, the derived model is thought to be meaningful enough. |
