We have a certified LEED-NCv4 project located on a site pursuing a LEED-ND certification. Since several buildings, including the LEED-NC project will be built at the same time, we would like to be able to merge each of them by using the « Group approach » for the construction waste management calculation.

As mentioned in the Reference Guide for Building Design and Construction: « All buildings in the group may be documented as one. Multiple buildings on a campus may share waste hauling contracts and on-site collection equipment. Data aggregation is allowed, provided that each building included is pursuing the same option.  

By same option, does it mean that all buildings compiled in the calculation must pursue LEED certification or is it the compliance option chosen for achieving the credit ?

Why can't we use the campus approach in this credit ?

Thank you,
