I have a telemarketing account that has aproximately 100 computers in approx. 1600 sf. The client is adding 56 more computers in this area. My question is, "Is there a rule of thumb for calculating cfm per computer in the space?". The space was originally used by insurance company which didn't have this heat load in it. I know I could get all the data on the space (ie.# of people, windows etc.) and use a program or ask an engineer. Any help would be appreciated.

Thanks,

Advantage
