Before we analyze the attributes, let's try to understand what we are dealing with. In total, there are eight attributes describing building characteristics, and there are also two target variables, the heating and cooling load, as shown in the following table:
| Attribute | Attribute name |
| 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 |
