[Equest-users] Baseline DOAS for LEED

[Paul Diglio]

Hi Folks:

I submitted a model to LEED of a 7 story apartment building.  In the proposed design a DOAS was specified because natural ventilation could not be provided per 62.1 due to the dimensions of the apartments.

Another issue is that the HVAC systems are Daikin VRF and they could not be supplied with directly ducted outside air due to the installation locations and the VRF cassettes do not have a fitting for an outside air duct.


The GBCI came back and said I could not include the DOAS in the baseline model.  The baseline HVAC system per 90.1 requirements are PTHP.  I responded to them twice with various reasons the DOAS needed to be included in the baseline but they won't budge.

Has anyone successfully addressed this type of design?

Thank you,

 
Paul Diglio
