Damaging Buildings

[The Dark]

In v2/v2.2, have any rules been put forward for damaging buildings other than the Breaching Barriers section of Demolitions? I haven't been able to find anything for vehicles hitting buildings (although collision rules could be used if the tonnage of the building was calculable), or for buildings collapsing (or partially collapsing) from damage. This seems...well, not exactly necessary, but at least an odd omission.
