Stand Alone Refrigerators and Freezers to be included in EAc4?

We have some large commercial catering refrigerators and freezers which are standalone and plugged into a normal power socket rather than integral to the building. The refrigerant charges of a couple of these are greater than 0.5lbs therefore I understand that these need to be considered for EAp3 and the EAc4 credit (EAp3 is straight forward). However the calculations for the EAc4 are based on Air Con systems and not refrig units. Has anyone successfully shown that they have a compliant refrigerator if they put it through the EAc4 calculator or is it always the case that the Building's chillers systems need to offset the non compliant refrigeration units. The ref guide talks about "all Base Building" systems in which case I would rather exclude the standalone catering equipment from the calculations but then again... the wording also suggests that anything over 0.5lbs needs to be accounted for. 1) Does off the shelf plug in catering equipment really need to be included in EAc4 2) Has anyone got any examples of compliant refrigerator or freezer units (EnergyStar listings are not helpful in this regard)? many thanks Viv
