Effects of Landscape Design on Urban Microclimate and Thermal Comfort in Tropical Climate

Table 7

Summary of the effect of different design scenarios on urban microclimate and thermal comfort (PET).

Design scenarios		Surface temp. reduction	Air temp. reduction	Mean radiant temp. reduction	PET reduction
1	Wooden boards	2–6°C	0–0.25°C for building-shaded areas	−8 to −4°C for building-shaded areas	No change
2	Light-color granite	2–12°C	0.25–0.75°C	−8 to −4°C for building-shaded areas	No change
3	Grass surface	2–8°C	0.25–0.5°C	4–8°C for areas exposed to the sun	4–8°C for limited areas
4	More trees	2–10°C	0.25–0.5°C	12–16°C for tree-shaded areas	4–12°C
5	More water bodies	No change	No change	No change	No change
6	Light-color granite and more trees	2–12°C	0.25–0.75°C	−8 to −4°C for building-shaded areas; 12–16°C for tree-shaded areas	4–12°C
7	Grass surface and more trees	2–10°C	0.25–0.75°C	4–8°C for areas exposed to the sun; 12–16°C for tree-shaded areas	4–12°C
