From the text in MPR3, it seems plausible that bike parking and showers used to meet credit SS4.2 could be built by renovation in another in another facility outside the project's LEED scope, as long as they meet distance requirements, but the energy use/water use/materials/etc etc all other elements used to create the bike area and showers would not be counted toward the LEED project?

The project in question here is a new 14 story full building addition to an existing two building complex. The intent is to certify the new building, the two existing buildings will have some renovation but are not and will not be certified. The buildigs are physically connected with circulation connecting them, but air spaces are separated by walls and doors, all plumbing and electricity systems will be separate, mechanically the air systems will be separate but heat/cooling water for mechanical will come from the same plant. We are working through the details of MPR2 and specifically "Buildings Attached to Non-LEED Certified Buildings" and have feedback that our approach is generally acceptable, but are looking for specific feedback on SS4.2.

In short:

Can the bike storage/shower areas be renovated in an existing building outside the LEED project scope, if they meet distance requirements?

If they count toward SSc4.2 but are outside the LEED project scope, do the components and systems that serve them get counted toward other credits (MR credits... energy model and EA credits... WE credits for the showers... etc)?
