A preliminary study on environmental performances of pocket parks in high-rise and high-density urban context in Hong Kong

This article reports the results of an empirical study on summertime environmental performances of a pocket park in Hong Kong. The results suggest that (i) wind condition has a critical impact on outdoor air temperature (Ta), especially in a tropical area like Hong Kong and (ii) building geometry is significantly related to outdoor Ta in Hong Kong. The shading effect from buildings may be more important than shading and evapotranspiration effect of greenery in the unique urban context of Hong Kong.
