<；P>；PROBLEM TO BE SOLVED: To provide a building installing structure capable of ensuring both of sufficient area for tree planting and sufficient area for receiving sunlight of a photovoltaic power generation panel. <；P>；SOLUTION: This building installing structure is constituted by providing a tree planting structural body 12 along an exterior face of a building 1 and fixing the see-through type photovoltaic power generation panel 41 at a position where it opposes to a tree planting face of the tree planting structural body 12. Consequently, the tree planting structural body 12 and the see-through type photovoltaic power generation panel 41 are arranged on planes being different from each other to receive sunlight on the see-through type photovoltaic power generation panel 41 and supply the sunlight passing through the see-through type photovoltaic power generation panel 41 into the tree planting structural body 12. <；P>；COPYRIGHT: (C)2010,JPO&INPIT
