The new ANSI/ASHRAE/USGBC/IES Green Building Standard 189.1-2009 serves as the jurisdictional requirement option for the new International Green Construction Code public version 1.0. Amazingly, the IGCC does have landscape implications: shading the building to reduce heat gain and therefore cooling costs; removal of invasives; reduced irrigation; management of soil and erosion control; bike facilities; managed lighting; reduced stormwater implications; and vegetation and soil protection areas (VSPA’s).
