Author: Angeliki Xifara, Athanasios Tsanas Source: UCI Please cite: Source: 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 (or features, denoted by X1...X8) and two responses (or outcomes, denoted by y1 and y2). The aim is to use the eight features to predict each of the two responses. Specifically: X1 Relative Compactness X2 Surface Area X3 Wall Area X4 Roof Area X5 Overall Height X6 Orientation X7 Glazing Area X8 Glazing Area Distribution y1 Heating Load y2 Cooling Load
