This is from Ontario building code:
----------------------------------------------------------------------------------------------------------------------
9.10.14.2. Area and Location of Exposing Building Face
(1) The area of an exposing building face shall be,
(a) taken as the exterior wall area facing in one direction on any side of a building, and
(b) calculated as,
(i) the total area measured from the finished ground level to the uppermost ceiling, or
(ii) the area for each fire compartment, where a building is divided into fire compartments by fire separations
with fire-resistance ratings not less than 45 min.
(2) For the purpose of using Table 9.10.14.4. to determine the maximum aggregate
-----------------------------------------------------------------------------------------------------------------------
Are there scenarios where an exterior wall area faces in more than one directions on any side of a building?
