What outside air ventilation rate would you use for plastics extruding?

Thanks

From the `09 IMC, Section 403.3:__"Ventilation rates for occupancies not

represented in Table 403.3 shall be those for a listed occupancy classification

that is most similar in terms of occupant density, activities and building

construction; or shall be determined by an approved engineering analysis."

Also, ...

From the `09 IECC, Section 503.2.1:__Calculation of heating and cooling loads:

"Design loads shall be determined in accordance with the procedures described in

the ASHRAE / ACCA Standard 183.......Heating and cooling loads shall be adjusted

to account for load reductions that are achieved when energy recovery systems

are utilized in the HVAC system in accordance with the ASHRAE HVAC Systems

and Equipment Handbook.......Alternatively, design loads shall be determined by

an approved equivalent computation procedure, using the design parameters

specified in :Next('./icod_iecc_2009_3_par001.htm')'>Chapter 3."

IMO, ...an engineered analysis & design will be required.
