In order to carry out a BB101:2018 performance analysis the model and data on target rooms need to be set-up in accordance with the requirements of standard.
This involves setting up weather, the background CO2 level plus importing and assigning prototype data to target rooms. The Navigator leads you through this process.
Importing prototype data adds room template data: profiles, gains and infiltration to the model.
The creation of a room group allows target rooms to be identified and the imported data changes to be applied to the target rooms quickly.

The changes applied to the target rooms are as follows:
Apsys methodology.
Room heating operation.
Room heating set-point variation profile.
Room cooling profile set to cooling operation.
Room occupancy profile.
Room lighting profile.
Room small power profile.
For template gains:
Occupancy gains 32 people 70/50W.
Lighting gains 7.2 W/m2.
Small power gains 10 W/m2.
Users can subsequently edit the gains as required within the limits of BB101:2018 if required.
Other changes made:
Infiltration 0.25 ACH continuously ON.
System o/a supply variation profile turned off.
Existing auxiliary ventilation air exchanges variation profile turned off.
Existing natural ventilation air exchange variation profile turned off.
