In response to your query
Am I correct in thinking – this is not included in iSBEM v 5.5 ?
If not included - how are cold rooms in restaurants / bars etc dealt with ?

The process load of a walk-in fridges or freezers should not be included in the iSBEMie analysis.

The zone types in the previous version of the software, cold or chilled stores, are no longer included as an activity types in iSBEMie.

To enter a cold or a chilled store, select activity type “Warehouse storage” or “24x7 Warehouse storage” under the building type “Storage or Distribution”.

The “refrigeration aspect” for this space is a process load since it is designed/provided for the goods and not for the thermal comfort of the occupants in the space and is, therefore, outside the scope of the energy uses which can be accessed via iSBEMie. As such, this zone should be defined as a “Zone without HVAC system” in the iSBEMie model.

Furthermore for conditioned spaces which surround this zone, the envelopes which are adjacent to this zone should be defined as adjacent to a “Conditioned adjoining space” so that no heat loss is calculated by the software from the surrounding zones through them since the envelopes of walk-in fridges are usually very well-insulated.

Note spaces which accommodate a considerable number of fridges/ freezers, such as in a supermarket or food hall are modelled in iSBEMie using activities such as “Small Shop Unit Sales area - chilled”, “Dept Store Sales area - chilled”, or “Retail Warehouse Sales area - chilled” under the building type “Retail and Financial/Professional services”.
