[Bldg-sim] About infiltration in a LEED analysis.....

[David GARCIA-SANCHEZ]

Hi all,

 

I'm modeling a building for a LEED certification (renovation) for a
building in France. 

 

Normally in my baseline and proposed models I put the same infiltration
(n50 = 0.14 ach) for both buildings. Even that this is an unreal case
(since the renovation leads to an improve in the permeability of the
building). 

 

I do that because, first 0.14 is the minimal infiltration allowed by
French regulations, and second because I have never seen in the ASHRAE
documentation about improve infiltration in current buildings. Even if
the improve of the infiltration rate can make me gain a lot of
improvement between baseline and proposed buildings energy
requeriements.

 

Anyone of you have already experience in this specific point? Any
justification is required from the USGBC if I want to change the
infiltration between baseline and proposed buildings?

 

Thanks in advance for any comments/help on this,

 

Regards,
David GARCIA-SANCHEZ
