求解,RC ledge 到底是干嘛用的?
7.12.3 RC ledge (for sunshading purpose only)
This exemption strictly applies to RC ledge located on the external façade of the building and is
not applicable to internal void space/courtyard.
RC ledge is defined as reinforced concrete plate outside the building without any railing or
parapet wall. The RC ledge must not exceed 2.0m. For RC ledge exceeding 2.0m wide, the area
to be excluded from GFA can be allowed up to 2.0m. The remaining portion has be counted as
GFA. The same method is applied to area exempted under the roof eaves.
