## 5. Feature modifications

The value of some features now go from 1 to 4 instead of 0 to 3. Like:

wall\_inulation, floor\_insulation, living\_room\_windows, bedroom\_windows and the new flat\_roof\_insulation, sloped\_roof\_insulation

For example: “mediocre” wall\_insulation was 1 and now it has the number 2
