In 2009, the construction of the passive solar house was estimated to be \$36, 579.55 with 1.00 USD equivalent to 11.76 ZAR, while its counterpart cost is \$8505.62 [21]. In spite of the cost margin, passive solar house presents a decent home com-

The floor plan was virtually partitioned into three thermal zones. Zone 1 marked with blue diagonal cross-hatch lines filled region is the living room/kitchen. The red diagonal up lines filled region used to indicate the north-facing bedroom is zone 2, while the south-facing bedroom is zone 3, represented by the region filled with green vertical lines.
