[Equest-users] LEED Baseline - Apartments

[Seth P. Spangler]

Susan,

 

I think I can answer your question - by clarifying another piece of
information that you offered up. For your baseline design the DOAU
should NOT be modeled unless it complies with the exception of G3.1.1 a
(2004) - - which I don't think it does (greater than 20,000 SF - that's
a lot corridor space). If it is not modeled in the baseline design then
by default your fossil fuel service goes away.

 

Thanks

I'm working on an apartment building and trying to figure out what my
baseline should be.  For the residential units, the proposed building is
split system heat pumps and supplemental electrical.  So for the
baseline I'm using PTHPs.  For the retail and other non-residential
areas which are mostly on one floor, the heating is electric so I'm
using System #4.  

The confusing piece to me is an outside air unit serving the corridors
of the residential area.  It has a gas-fired furnace that is heating the
air to 70degF.  It is the only fossil fuel device in the building and
I'm not sure that the baseline should be hybrid for this.  I have a
feeling that a hybrid baseline will hurt me.

Has anyone done anything similar in the past?  What has worked for the
LEED reviewers?

Thanks in advance.
