10.0pt;font-family:Arial;color:navy'>I agree with your sense of
disappointment. Although I’m not convinced 62.1 provides sufficient
OSA for ventilation in some cases and provides over ventilation at times, the
intent of 90.1 is to reduce energy consumption. Even though I generally
prefer to provide more than the minimum OSA mandated in 62.1, the intent of
LEED is to promote reducing energy consumption in buildings. Providing
OSA rates greater than the rates directed in 62.1 typically requires spending a
bit more time with design in order to minimize the impact of the additional
ventilation air. It is reasonable to assume that LEED should recognize
buildings provided with more than the minimum OSA required to meet 62.1 should
either require creative means to minimize the energy impact of additional ventilation
or be penalized for increasing the ventilation rate.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=blue face=Univers><span style='font-size:
10.0pt;font-family:Univers;color:blue'>This is a case of where LEED, IMHO,
should supersede 90.1. I’m very surprised, and quite frankly
disappointed, about Nathan’s comments that the USGBC has accepted 30%
over-ventilation in the baseline building. The intent of LEED, among
other things, is to promote low-energy building design. If a designer
chooses to over-ventilate a building by 30% over what is required by ASHRAE in
order to achieve better indoor air quality, the occupants are better off, the
environment is not. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=blue face=Univers><span style='font-size:
10.0pt;font-family:Univers;color:blue'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=blue face=Univers><span style='font-size:
10.0pt;font-family:Univers;color:blue'>The bottom-line is that the baseline
building “could” have been ventilated at ASHRAE rates, and the
proposed design should be penalized for not complying with accepted practice.
It’s no different than if the proposed chiller had a lower COP compared
to 90.1 baseline. 90.1 and ASHRAE define currently accepted practice and the
proposed design should be judged against the standard, not against itself. It’s
just that in this case there is a side-benefit of using more energy and 90.1
stipulates using the same ventilation rates, which muddies the issue.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=blue face=Univers><span style='font-size:
10.0pt;font-family:Univers;color:blue'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=blue face=Univers><span style='font-size:
10.0pt;font-family:Univers;color:blue'>I think the example of the hospital is a
red herring, since hospitals would not be designed to ASHRAE 90.1, rather more
stringent ventilation codes which would be applied to both the reference and
proposed buildings. The result is compliance-neutral. Choosing to
ventilate beyond governing standards, should be considered bad design practice
in terms of energy, even though it’s considered good design practice for
other reasons. We can’t have our cake and eat it too!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Calibri><span
style='font-size:11.0pt;color:black'>These are separate credits – the
modeling takes place based on the proposed design in comparison to a baseline
that is only restricted by 90.1. The OA requirement should be the same in
both models subject to any DCV or exceptional calcs or technologies. This
is not affected by other LEED credits. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Calibri><span
style='font-size:11.0pt;color:black'>The credit for increased ventilation takes
place “before” modeling starts. This is besides the many
cases for laboratories or hospitals where the local code ventilation
requirements are much greater than ASHRAE 62.1 already – the proposed
design is in effect already taking the EAC1 penalty but earning the credit for
increased ventilation under the best practice design. You wouldn’t
relax the baseline ventilation to less than 30% in these cases!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Calibri><span
style='font-size:11.0pt;color:black'>I’m sure there are some proposed
buildings out there that condition OA very effectively, and may gain EAC1 gross
energy cost savings by having increased ventilation, but even where that effect
occurs there is the question of percentage savings applying to a larger
energy consumption and cost.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Calibri><span
style='font-size:11.0pt;color:black'>Overall if you gain EAC1 points by
pursuing increased ventilation, I think you have worked well within the system
– good for you in designing a system to condition outside air so
effectively. For many projects (other than labs or hospitals which may
have to use that quantity of OA anyway) I would expect EQC2 could be trading
for an EAC1 credit, so you’ll have to prioritize. Both are rewarded
from USGBC, but EAC1 is also rewarded in lower utility bills.<o:p></o:p></span></font></p>
