A relevant data selection method for energy consumption prediction of low energy building based on support vector machine

This work focuses on artificial intelligence (AI) model to predict energy consumption of LEB. Two kinds of AI modeling approaches: “all data” and “relevant data” are considered. The “all data” uses all available training data and “relevant data” uses a small representative day dataset and addresses the complexity of building non-linear dynamics by introducing past day climatic impacts behavior. This extraction is based on dynamic time warping pattern recognition methods. The case study consists of a French residential LEB. The numerical results showed that “relevant data” modeling approach that relies on small representative data selection has higher accuracy (R2 = 0.98; RMSE = 3.4) than “all data” modeling approach (R2 = 0.93; RMSE = 7.1) to predict heating energy load.
