“…There are two fundamental approaches for zoning. One approach is that the zoning is applied with the aid of a computer design tool (Mora et al, 2004), figure 1, whereas another approach is that zoning is a part of a more or less autonomous design solution cycle (Hofmeyer et al, 2005), figure 2. The last mentioned approach can be compared with the approach of shape grammars that generate design solutions (Kotsopoulos, 2005), often used for space related problems but here applied to structural design problems.…”
