Source This dataset was obtained from the UCI Repository. The dataset was created by Angeliki Xifara (angxifara '@' gmail.com, Civil/Structural Engineer) and was processed by Athanasios Tsanas (tsanasthanasis '@' gmail.com, Oxford Centre for Industrial and Applied Mathematics, University of Oxford, UK). Data Set Information: We perform energy analysis using 12 different building shapes simulated in Ecotect. The buildings differ with respect to the glazing area, the glazing area distribution, and the orientation, amongst other parameters. We simulate various settings as functions of the afore-mentioned characteristics to obtain 768 building shapes. The dataset comprises 768 samples and 8 features, aiming to predict two real valued responses. It can also be used as a multi-class classification problem if the response is rounded to the nearest integer. Attribute Information The dataset contains eight attributes and two responses. In the original data, the aim is to use the eight features to predict each of the two responses. For this version of the dataset however, only the *Heating Load* is used as the target, while the *Cooling Load* is being ignored. In addition, the variables were renamed to be more meaningful.
