[Equest-users] natural ventilation scenario and LEED

[Christian Stalberg]

Joe,

 

Okay let me elaborate further.

 

This high bay warehouse building has no HVAC whatsoever. Not even ventilation fans. Only fixed openings distributed across the walls and at the roof. I do not know if LEED specifies modeling only operable windows, but that is the example they give in their guidebook. Again, I do not know if this building would even qualify as enclosed space and therefore be eligible for modeling. I have looked everywhere including the LEEDuser forum and am unable to shed light on this issue. 

 

Regards,

Christian,

I'm still unclear what is the conundrum.  Is it that LEED modeling rules only specify operable natural ventilation, or that you're unclear how to model fixed, i.e., uncontrolled,  natural ventilation?

I’m getting no responses on the bldg-sim list so am trying here too. 

  

I have a factory/warehouse that is using natural ventilation for cooling. What is unusual is that the openings are fixed openings. 

  

At first glance it seems that it would not even qualify as an enclosed space and therefore would not be eligible for energy modeling for LEED. The project is registered at USGBC however, of course I realize that may mean nothing. 

  

If this project could be eligible for LEED certification, I am trying to come up with an approach and all I can think of is pretending the openings are operable and then following the guidelines as outlined in the Advanced Energy Modeling for LEED handbook. 

  

I would appreciate any guidance anyone can offer on this seeming conundrum!
