Hi.

I'm working with a building that has a VAV that supplies OA to a single room based on the numbers of people on that space. Is it acceptable to submit a regular excel spreadsheet with the Voz calculation instead of using the 62MZ spreadsheet?

Thanks in advance,

Is it a single zone VAV air handler or is your project scope only one VAV on a multizone variable system? If it's only a single zone VAV AHU then you should just use the template for ease. If it is a full system then you will probably have to model the whole system to show that your zone is getting the correct OA flow under all conditions.

I am sure that's not the answer you are looking for but it's the most correct answer in my opinion.

Hi Andrew,

It is a very small building, we have a single office space per floor, with a single VAV per floor, each VAV supplies air to it's floor office only.

What do you mean by "use the template"? Are you referring to the 62MZ spreadsheet?

Thank you!

Noriko, your description sounds like it is a multi-zone VAV system. You did not actually describe the air handling unit type so that is what I am inferring. If this is the case then simply use the 62MZ spreadsheet. If it is one zone per air handling unit then use the template. By template, I mean the credit form on leedonline.com.
