[Bldg-sim] Exhaust Fans in Baseline

[Vinay Devanathan]

Vikram,

Thanks for your reply.

So, does it mean I will have to model the exhaust fan in the baseline model
but in a fashion such that it consumes power proportionate to your proposed
design (supply, return and exhaust) but falls within the Allowable Fan
System bhp value of Appendix G. Am I right?

Thank you.

Regards,
Vinay
