The idea would be to be able to exploit the raw statistics in order to carry out regulatory audits, by designating walls as overlooking the outside or unheated premises (ditto for the low floor) we could have wasting surfaces. A concept of N, S, E, W orientation should also be added

So we could extract:

1 bedroom wall: 190S, 29m2

Joinery: 3m2

Wall 2 bedroom: 84E 18m2

Joinery: NP

Etcc.

Thanks for the attention,

Have a nice day.
