I'm trying to input a student accommodation building into Part L - each apartment has a bedroom and ensuite with the overall apartment having a dedicated HRU, the results on the BRUKL document criterion 2 show the ventilation system as being type A and type D when surely the results should be just a type D. I've tried to find an answer but seem to be drawing a blank. Any ideas ?
Thanks for that Duncan, the only thing I don't understand is that the HRU we are using is supposed to be better than Part L requirements but the results in the BRUKL shows it failing on the type A. It just seems to me that the ability to input a local HRU to an apartment is limited, therefore I was wondering if I was inputting it incorrectly or is it just a function of the SBEM program.
Cheers

There's certainly some interesting things going on there. I note that the wording for the system types is slightly different - Type A being local supply OR extract ventilation. Type D being local supply AND extract ventilation. It also seems that the Supply SFP is deciding whether Type D is selected, and the Extract SFP is deciding whether Type A is selected.Your data is fine - you can use the data reflection report to check it - its definitely a vagary of the SBEM calculation engine.Regards,
