Comparison of leaf area index from four plant species on vertical greenery system in Pasir Gudang, Malaysia

Vertical greenery system (VGS) is a subset of urban green infrastructure that ameliorates thermal performance, potential energy savings, and urban heat island. Plants provide shadow effects through the absorption or filtration of the heat radiant, which respond to these issues. The frequent variable...
