Energy simulator

When we carry out heat gain calculations the fresh air volume does not appear to be correct. This room should have 50 people at 12 litres/sec therefore the fresh air should read 0.6m3/s however it reads 0.0322m3/s.

We have altered several settings yet this figure does not change. 

Please can you advise on how to change this figure as the heat gains will be incorrect if the fresh air volume is not correct.

Thanks

Steve
