Hello everyone,
We have a C&S project: a logistics center in Netherlands. This center has a main warehouse area (406m*304m) and will have natural ventilation through openings in its roof (roof vents) and the building’s perimeter walls. According to LEED Reference Guide, we should review ASHRAE 60.1-2010 standard and CIBSE AM10. There will not be heating or cooling since it is intended as a storage area (no additional activities done by people), therefore this space’s internal environment will not have any temperature control. According to Figure 2.8 in CIBSE AM10, mechanical ventilation is required but this space is not intended to be regularly occupied. Futhermore, ASHRAE’s exception 2 in section 6.4 establishes that no mechanical ventilation is required if the zone is not served by heating or cooling equipment which in some way annuls what CIBSE’s Figure 2.8 mentions.
My questions are: Since the zone will not be regularly occupied and according to ASHRAE 62.1-2010 exception 2, is it acceptable to not install mechanical ventilation?
Also, can we use a CFD simulation of the warehouse’s natural ventilation behavior as an alternative methodology to demonstrate de prerrequisite’s compliance? We intend to prove there is air circulating through the warehouse’s openings. Or would additional calculations must be submitted? Any reference recommendations for this topic is really appreciated.
Thanks in advance.
