The wall & roof material properties of the studied green building might be one of the major reasons to explain the insignificantenergy saving performance of green vegetation. Although thereare published literatures that have confirmed the excellent energysaving performance of green vegetation in different buildings, therelationships between the properties of the building fac¸ ade andthe energy saving performance was not fully considered in suchpublications [15,21–23]. The studied green building is a newly con-structed building with the LEED Gold standard. Thus, the buildingfac¸ ade has already been constructed to earn the LEED points inenergy savings. This research confirmed that the green vegetationhas no significant impact on the energy savings in LEED standardbuildings, such as the studied green building
