show the orthophoto, NDVI pattern and surface temperature maps of Subang Ria
Recreational Park. The surrounding areas consist of multiple land use (i.e. high-
way, high-rise building, private club and residential areas). Based on Figs.

,

and

, it is evident that the vegetation can help to reduce of the hard surface emissivity
and lowering the solar exposure of the building envelope as well as cooling down
the high temperature in built-up areas.
