We are currently working for a LEED project - industrial building creating petfood - under NC V4 scheme. We are facing some difficulties to understand wich rooms need fresh air and following which type of room according to ASHREA 62.1-2010. We have this kind of following areas, occupied according to LEED definition :
Grinder room ; bin washing ; thawing room ; dryer area ; bin storage ; raw material receiving ; ingredient preparation ; liquid production...
We would like to know if there are some rules to exclude some typical area which need some exausts, and if need to consider these areas only as general manufacturing areas.
Thanks in advance if you have some inputs for us !
