Thank you everyone for your inputs!

Hi lukaiENG, thank you for your inputs. 1. We're planning on using airflow measuring stations to control the relief fan. 2. We do have an airside economizer and yes, it looks like the unit was selected for 100% return air already. Will having all that static on the supply fan be a problem? It...

Hello Everyone! I was wondering if anyone here has used a relief fan on a ducted return system. We usually go with a return fan but due to budgetary and size constraints are contemplating on using a relief fan for the unit. I was wondering if anyone here has done this and could share their...

I would concur with what everyone is saying out here. Revit is slowly becoming a standard program for design at least, not sure how far it is being used to do load calculations.

I was thinking on the same lines. Thanks MintJulep!

No, the radiator itself is mounted on the roof. But we'd still need to handle the heat load from the generator. I'll look up the manufacturer's specs and see what they have to say. Thanks chicopee and willard3 for your advice.

Well, for the cooling air, can it be coming from a cooling coil? Because one of the concerns is that if we're using a cooling coil and if it failed at the same time that the generator was required, then you'd end up with inadequate cooling and so we're trying to see if there is any code...

Hello everyone, I was looking for requirements on ventilating a generator room. Does it have to only be naturally ventilated? I've looked at NFPA 110 (2008) but it seems ambiguous.

Hello Everyone, Thank you all for your comments, thoughts, experiences and suggestions. I really appreciate it and feel that I should probably postpone the idea of becoming a Registered Analyst till it gains recognition. But would you recommend that I get any kind of certification that would...

Hello Everyone, I was planning on taking the NAFEMS Registered Analyst Scheme. I have recently graduated and intend to build a career in FEA. I was looking for some advice on how recognized the Scheme is and any other experience from you that I should keep in mind? Thank you, Regards.

Thank you!......that was very helpful.....

Hi experts, Could someone tell me where are stresses and displacements calculated? Are they calculated at the nodes or at the integration points? Thanks and regards, Siddharth Premkumar.
