My project has a cellar level that extends beyond the building footprint. At street-level, there will be a plaza constructed over this portion of the cellar level which includes vegetation, pavers and seating - this plaza is 100% of the project's non-roof area. However, I just want to verify that this street-level plaza will not somehow fall into the 'roof' category since there will be conditioned corridors, storage and IT room in the cellar below. Logically, this exterior plaza is non-roof but I just don't want to run into any complications with LEED definitions - all of the LEED Interpretations I found only addressed below-grade parking but did not specify what to do with cellar spaces covered by sidewalk/landscape/etc. Thanks in advance for sharing any experience or input on this!
