For buildings including rooms that are not served by comfort cooling, a check against Criterion 3 is required.
The recommended procedure is to use method b, which is based on operative temperature statistics in these rooms.
Click on the button labelled ‘Summer temperature check (actual building)’. This displays an interface for performing summer temperature simulations. You will need to assign or check the settings, including the following:
Results file – the name you enter here (prefixed by ‘s_=’) will be used to store the results of the simulation, which can be viewed in Vista.

Note that the settings appearing here are shared, where appropriate, with other <VE> Compliance simulations. However, you will need to set the simulation period. A whole year’s simulation is normally appropriate, but there is some flexibility in the rules.
Document L2A should be consulted for the requirements governing summer temperature performance.
At the end of the simulation a report is generated on the incidence of high temperatures in the rooms without comfort cooling, which can form part of your Part L2 submission.
