Iteration 1

Iterations 01/A-C features simulations based on one block typology situated in the three road networks described in the introduction of this chapter.

01 / A

Typology Diagram
Figure: Typology Diagram

Iteration 01/A features the first block typology where the upper one-third of the plot is allocated for shops on ground level, offices above it, and two smaller residential blocks 3-6m away from the commercial block with an ample amount of courtyard space in the middle of the three blocks. Situated in the control grid road network, commercial blocks will be clustered towards the AYE to act as a noise buffer for the residential blocks, which will be clustered towards the MRT nodes.

    Evaluation

    Of the three iterations above, the grid control system 01/A achieved the most number of good buildings and windows overall. Of the two other road networks, the mixed system of parallel and irregular roads 01/C fared better in terms of the percentage of windows with unobstructed views, passive area ratio and solar factor.
