If a CI project is located in a CS building and the tenant requires no fit out, can EPDs for products in the tenants space in the CS certification be used for the CI certification? And so forth for the other BPDO credits?

If a minor fit out is done, installing less than 20 new products (e.g. only 10 new products) - do all 10 have to have EPDs to earn 1 point in Option 1?
