[Bldg-sim] warehouse ventilation design

[Cam Fitzgerald]

A work of caution


Technically LEED projects are required to use the VRP method (not the IAQ
method) to determine the minimum required ventilation airflows for projects.

Look at the IAQ procedure in ASHRAE 62.1, Wused it in a LEED certified
refrigerated warehouse, it did reduce by a large amount the outside air.

Take a look at ASHRAE 62.2, it establishes minimum ventilation rates for
various occupancies.

Dear All,
 
On a large warehouse (shipping & distribution center) project, we're told by
our consultant that the 650,000 square feet warehouse component is being
designed to be ventilated (OA) at 0.06 cfm/sf. There are small portions with
multiple levels, total ventilation CFM ends up being close to 60,000. (we're
told by our consultant that this is the code minimum). CO2 sensors are being
planned to bring the OA levels down, not yet sure what the thresholds are.
 
The office component that is a tenth in square footage but roughly equal
occupancy as the warehouse, results in around 15,000 CFM ventilation. 
 
While we generally trust our consultant's professional judgement, the design
team is concerned that the warehouse ventilation might be over designed. Is
anyone aware of workarounds that meet code but effectively optimize the
ventilation/OA rates in such large warehouse settings?
 
Thank you,
Ramana Koti.
