At present, the electrification of the University. Guard is a trend toward higher. Predictive power advance so there is a huge need. In order to know the power of the university. Guard it in any direction. This paper proposes two methods of forecasting all types Linear Regression and ARIMA for forecasting of electric power engineering building. University guards in the future, offer a way to reduce electricity consumption. The criteria used to compare the accuracy of the forecast is the average of absolute value. Percentage error (MAPE) and the coefficient of determination (R-Square), which means that the average absolute value. Percentage error (MAPE) and the lowest R-Square, close to one. Will be used to forecast electricity use in the future.
