Surfacing effects on thermal condition in urban open space / Liyana Ahmad Bazuli and Azhan Abdul Aziz

Urban density has significant impacts in shaping the microclimatic condition of urban milieu. Studies related to
global warming and environmental hazard effecting climate condition particularly in urban open space indicates
constructive outcomes of escalating temperature caused by poor design strategies and adaptation. Hence, the aim
of this study is to identify and assess the elements and prospects of existing open space towards outdoor thermal
condition and discomfort of urban environments while preserving the ideal state of quality of life. Measures
involve physical microclimatic parameters (radiant temperature, air velocity and relative humidity) and
calculations of natural and manmade topographies in two identical open spaces. Meteorological assessments was
conducted at designated zones for three (3) days in June at 1.1meter above ground level with five (5) and ten (10)
minutes time interval.The preliminary findings revealed that the morphological characteristicsand total area of natural and manmadeelements affect the thermal condition of urban open spaces. However, further empirical research is required to include other associated parameters i.e. types of vegetation and materials promoting ideal thermal environments.
