Iteration 3 Regularized Grid with Primary and Secondary Roads (Bent and Heterogeneous)

Iteration C

In this iteration, a standard tower typology is explored to investigate its efficiency, should developers be interested to build a tower without a central courtyard.

Figure 14. Block typology and Urban morphology for Iteration 3c

Set-up

The distribution of residential and commercial area is as follows

• Residential: 22sqm per person
• Commercial: 13sqm per person

  Parameters for urban morphology

• Residential storey height: 3m
• Commercial storey height: 5m
• Green connector road 15m
• Green buffer 5m (each side)
• Primary roads 8m
• Secondary roads
• Pedestrian roads 1.5m
• Parks < 500sqm

  Urban morphology

• Maximum floor count: 31
• Average floor count: 7
• Total number of buildings: 170

Building Simulation

Figure 13a. Iteration 3c Building simulations

Good Building = 76.69%

• Daylight factor = 62.18%
• Passive ratio = 98.36%
• Solar Factor = 82.18%

Figure 13b. Iteration 3c Building simulations

Good Window =36.95%

• View Factor = 62.82%
• Good window ratio = 77.64%

Evaluation

Comparing Iteration 3C with Iteration 3B, Good buildings have became worse, with 76.69% of good buildings, down from its previous 83.68%. While Good Windows seems to have increased to 36.95%, in reality, this option is worse-off due to the mis-opportunity for the tower blocks to contain courtyard gardens which would significantly increase its good window ratio.
