Dear all, 


The VAV minimum set point for system 7 in Appendix G is calculated based on
(0.4 cfm/ft2). For some spaces this number is bigger than the calculated
design airflow based on 20F delta T. What should the VAV set points be in
this case? 




VAVmin = 131 l/s

Design Air Flow = 84 l/s 

Fresh Air = 108 l/s


Thank you for your input,
