The intent of the following wording in the technical manuals is to exclude self-contained refrigeration units.
NC 2018 Ene 05: “The scope of this issue covers freezer or cold storage rooms which are integral to the building and served by the building’s own refrigeration systems.”
NC 2016 Ene 05: “If the building contains no refrigeration systems or only refrigeration systems which stand-alone, i.e. are not integral to the building and served by the building services, this issue is not applicable to the assessment.
The scope of this issue covers freezer or cold storage rooms which are integral to the building, and includes cooling systems that require commissioning and optimisation for the specific requirements of the cold storage space. This applies whether the cold storage space has a dedicated cooling system serving this space, or one which is connected to wider building cooling services.
“Kitchen and catering facilities”, are excluded from this issue. They refer to commercial-sized, but self-contained, off-the-shelf units – these include large freezers, fridges, or stand-alone self-contained walk-in cold storage units. These types of units are manufactured as a self-contained product, and contain their own integral cooling systems – they operate according to manufacturer pre-sets, and do not require commissioning of the cooling system.
For this reason, these are not assessed under this issue, but they may still fall within the scope of the ‘Energy efficient equipment’ issue.
The guidance will be clarified in future reissues or updates of the technical manuals.
